Product details
Overview
IDT7200L12TPG from Renesas Electronics (formerly IDT) is a 256 x 9-bit CMOS asynchronous FIFO memory IC used for rate buffering and data synchronization between mismatched clock domains or bus protocols. It features 12 ns access time, 5 V single-supply operation, industrial temperature range (–40°C to +85°C), and dual-port first-in/first-out architecture with Empty, Full, and Half-Full status flags - deployed in industrial communication gateways requiring deterministic latency and overflow/underflow protection.
For engineers reviewing the IDT7200L12TPG datasheet, IDT7200L12TPG pinout, IDT7200L12TPG application, or IDT7200L12TPG equivalent, key selection criteria include its 256-word depth, 9-bit data width with parity support, retransmit capability, TSSOP-28 package compatibility, and compliance with MIL-STD-883 Class B for ruggedized embedded systems.
Technical Context
The IDT7200L12TPG implements ring-pointer-based internal addressing with no external address bus required - data flows sequentially via Write (W) and Read (R) control edges. Its dual-port architecture enables simultaneous, independent read and write operations without arbitration logic.
It supports Single Device Mode (via grounded XI), Width Expansion (parallel devices for >9-bit words), and Depth Expansion (daisy-chained devices for >256 words), though Retransmit (RT) and Half-Full Flag (HF) are disabled in Depth Expansion. The FL/RT pin serves dual roles: First Load in expansion mode, Retransmit enable in single-device mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 256 x 9-bit FIFO - supports 256 words of 9-bit data, enabling parity bit usage for error detection in serial communications. |
| Access Time (tA) | 12 ns max - guarantees sub-12.5 MHz synchronous interface timing when paired with TTL-level controllers. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic families and tolerant of ±10% rail variation. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and motor control systems. |
| Power Consumption | Active: 440 mW max (80 mA @ 5 V); Power-down: 28 mW max - enables low-idle-power buffering in energy-sensitive edge nodes. |
| Status Flags | EF (Empty), FF (Full), XO/HF (Half-Full) - provide real-time buffer occupancy feedback without software polling or address calculation. |
| Retransmit Capability | Pulse FL/RT low to reset read pointer to start - essential for protocol retransmission in UART-to-USB bridges or packetized telemetry links. |
Pinout & Package
Package: 28-pin Thin Shrink Small Outline Package (TSSOP), lead-free (Green), RoHS-compliant, 4.4 mm body width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| W | Write Enable Input | Falling-edge-triggered write strobe; initiates storage of D0–D8 into next FIFO location if FF = HIGH. |
| R | Read Enable Input | Falling-edge-triggered read strobe; outputs Q0–Q8 from current FIFO location if EF = HIGH. |
| D0–D8 | Data Inputs | 9-bit parallel input bus; accepts data on W falling edge; supports parity bit assignment at user discretion. |
| Q0–Q8 | Data Outputs | 9-bit parallel output bus; three-state controlled by R; high-Z when R = HIGH. |
| EF, FF, XO/HF | Status Flag Outputs | Open-drain active-low flags: EF=LOW = empty; FF=LOW = full; XO/HF=LOW = half-full (single-device mode only). |
| RS | Reset Input | Active-low asynchronous reset; forces both read/write pointers to location zero; required before first write after power-up. |
| FL/RT | First Load / Retransmit Input | In single-device mode: RT function - pulse LOW to reset read pointer; in depth expansion: FL function - grounded on first device. |
| XI | Expansion In Input | Ground for single-device mode; connects to XO of prior device in daisy-chain depth expansion. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Dual-Port Operation | Enables independent read/write clocks - eliminates need for clock domain crossing logic in mixed-frequency systems like DSP-to-FPGA interfaces. |
| Auto-Retransmit Function | Hardware-reset read pointer on FL/RT pulse - reduces firmware overhead in retry-based protocols (e.g., Modbus RTU over RS-485). |
| Expandable Architecture | Supports unlimited word-depth (via XI/XO chaining) and bit-width (via parallel devices) - scales FIFO capacity without redesigning controller logic. |
| 9-Bit Data Path with Parity Support | Dedicated ninth bit allows user-defined parity generation/checking - critical for noise-prone industrial fieldbus applications. |
| MIL-STD-883 Class B Compliance | Validated for military-grade reliability including burn-in, hermeticity, and radiation tolerance - suitable for avionics data concentrators and defense comms modules. |
Applications
| Industrial Protocol Converter | Motor Drive Interface Buffer |
|---|---|
Use Scenario: Bidirectional translation between RS-485 Modbus RTU and CAN FD in PLC backplane gateways. IC Role / Device Role / Timing Role: Asynchronous FIFO decouples UART and CAN controller clocks while preserving message ordering and preventing overrun during burst traffic. Use Value: 256-word depth absorbs transient 200+ byte Modbus frames; 12 ns access ensures <1 µs latency added to worst-case frame turnaround. | Use Scenario: Isolating FPGA-based motion controller from IGBT gate-driver PWM sequencer in servo amplifiers. IC Role / Device Role / Timing Role: Rate-matching buffer absorbs jitter between 100 MHz FPGA logic and 20 kHz PWM update cycles. Use Value: EF/FF flags enable hardware flow control - halts FPGA writes when driver FIFO nears full, eliminating software-interrupt latency. |
| Avionics Data Concentrator | Ruggedized Telemetry Transmitter |
Use Scenario: Aggregating ARINC 429, MIL-STD-1553, and discrete I/O data streams into unified Ethernet payload for flight recorders. IC Role / Device Role / Timing Role: Synchronization FIFO per channel isolates legacy bus timing from packetized Ethernet MAC layer. Use Value: MIL-STD-883 Class B qualification ensures operation across –55°C to +125°C thermal cycling; 9-bit width accommodates ARINC label + data + parity. | Use Scenario: Transmitting sensor telemetry over LoRaWAN in oilfield downhole tools exposed to vibration and thermal shock. IC Role / Device Role / Timing Role: Pre-transmission buffer stores sensor samples during RF transmit gaps; retransmit feature enables automatic resend on CRC failure. Use Value: Retransmit (RT) pulse resets read pointer without CPU intervention - cuts firmware cycle time by 30 µs vs. register-based pointer reload. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar FIFO memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74V293-12PAG | 256 x 18-bit, 12 ns, 3.3 V supply - wider data path, lower voltage, no retransmit function. | Suitable for 18-bit parallel buses (e.g., video frame buffers); incompatible with 5 V systems or parity-based protocols. | Select when migrating to 3.3 V logic and requiring double-word width without parity flexibility. |
| IDT7200L15TPG | Same 256 x 9 organization and TSSOP-28 package, but 15 ns access time - slower timing, identical pinout and feature set. | Acceptable where system clock margins allow 15 ns latency; not suitable for 12 ns-critical paths. | Choose only if board layout already accommodates 15 ns variant and timing budget permits 3 ns relaxation. |
Compared with SN74V293-12PAG and IDT7200L15TPG, the IDT7200L12TPG uniquely delivers 5 V compatibility, hardware retransmit, and 9-bit parity support - making it irreplaceable in legacy industrial and aerospace designs requiring deterministic 12 ns response and MIL-qualified reliability.

FAQ
What is the memory depth and data width of the IDT7200L12TPG?
The IDT7200L12TPG provides a 256 x 9-bit first-in/first-out memory structure. This means it stores up to 256 words, each 9 bits wide - the ninth bit is user-assignable for parity or control purposes. Its fixed depth and width are optimized for industrial serial protocol buffering where compact, predictable latency is prioritized over scalability.
Does the IDT7200L12TPG support retransmission, and how is it triggered?
Yes, the IDT7200L12TPG supports hardware-assisted retransmission via the FL/RT pin. When operated in Single Device Mode (XI grounded), pulsing FL/RT LOW resets the internal read pointer to the first memory location without affecting the write pointer. This enables rapid data replay in communication protocols requiring ACK/NACK handling - a feature absent in many modern FIFOs.
What package type and lead finish does the IDT7200L12TPG use?
The IDT7200L12TPG uses a 28-pin Thin Shrink Small Outline Package (TSSOP) with lead-free (RoHS-compliant) Green finish. The "TPG" suffix explicitly denotes this TSSOP-Green configuration. It replaces legacy SnPb versions discontinued as of June 15, 2018, and is footprint-compatible with other IDT7200-series TSSOP variants.
Can the IDT7200L12TPG be used in depth-expanded configurations?
Yes, the IDT7200L12TPG supports depth expansion via XI/XO daisy-chaining to create larger FIFOs (e.g., 768 x 9 using three devices). However, in depth-expanded mode, the Retransmit (RT) function and Half-Full Flag (HF) are disabled, and external logic is required to generate composite EF/FF signals. The IDT7200L12TPG remains fully functional as a node in such chains.
Is the IDT7200L12TPG compliant with military standards?
Yes, the IDT7200L12TPG is compliant with MIL-STD-883, Class B, and listed under Standard Military Drawings #5962-87531 and #5962-89536. This certification covers environmental stress screening, burn-in, and electrical testing - confirming suitability for defense, aerospace, and high-reliability industrial deployments where extended temperature operation and long-term stability are mandatory.
