Product details
Overview
72V01L25JGI8 from Renesas Electronics (formerly IDT) is a 3.3 V CMOS asynchronous FIFO memory with 512 × 9-bit depth, 15 ns access time, industrial temperature range (–40°C to +85°C), and 32-pin PLCC package. It supports simultaneous read/write operations, auto-retransmit, and status flags (Empty, Full, Half-Full), used in rate-matching buffers for data communications and multiprocessing systems.
For engineers reviewing the 72V01L25JGI8 datasheet, 72V01L25JGI8 pinout, 72V01L25JGI8 application, or 72V01L25JGI8 equivalent, key selection criteria include its 25 ns speed grade, low-power active/standby current (60 mA / 5 mA), dual-port asynchronous architecture, and compatibility with legacy 720x family designs requiring stable timing and overflow/underflow protection.
Technical Context
The 72V01L25JGI8 implements a ring-pointer-based FIFO architecture with no external address bus, enabling first-in/first-out data flow via dedicated Write (W) and Read (R) control lines. Its internal RAM array is 512 × 9 bits, supporting parity or control bit allocation across the 9-bit data path (D0–D8/Q0–Q8).
It operates in Single Device Mode when Expansion In (XI) is grounded, enabling Half-Full Flag (XO/HF) output and Retransmit (FL/RT) functionality; Depth Expansion requires cascading via XI/XO and disables RT/HF. All timing parameters-including tA = 25 ns, tRC = 35 ns, and tWC = 35 ns-are specified at VCC = 3.3 V ± 0.3 V over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 512 × 9-bit (4,608-bit total capacity; supports 9-bit data with optional parity/control) |
| Access Time (tA) | 25 ns maximum - determines minimum cycle time for reliable read/write setup/hold compliance |
| Supply Voltage | 3.0 V to 3.6 V - compatible with 3.3 V logic systems; rejects noise within ±0.3 V tolerance |
| Active Current (ICC1) | 60 mA max at 20 MHz - enables low-heat operation in dense PCB layouts |
| Standby Current (IICC2) | 5 mA max - reduces power in idle states without full shutdown |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments including factory automation and telecom infrastructure |
| Package | 32-pin PLCC (J32-1) - surface-mountable, leaded package with standard JEDEC footprint and thermal mass for reworkability |
Pinout & Package
72V01L25JGI8 is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC, order code J), with gull-wing leads and index corner marking. The package meets JEDEC MO-047AB standards and supports infrared reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D8 | Data Input Bus | 9-bit parallel input path; accepts TTL/CMOS-compatible signals for FIFO loading |
| Q0–Q8 | Data Output Bus | Three-state outputs driven only during valid read cycles; high-impedance otherwise |
| W | Write Enable | Falling-edge-triggered write strobe; initiates storage of D0–D8 into next FIFO location if FF = HIGH |
| R | Read Enable | Falling-edge-triggered read strobe; outputs Q0–Q8 from current FIFO location if EF = HIGH |
| RS | Reset Input | Active-Low synchronous reset; forces both read/write pointers to zero and sets EF = LOW, FF = HIGH |
| FL/RT | First Load / Retransmit | In Single Device Mode: pulsed LOW to reset read pointer to start for retransmission; not functional in Depth Expansion |
| XI | Expansion In | Grounded for Single Device Mode; tied to XO of prior device in Depth Expansion chain |
| XO/HF | Expansion Out / Half-Full Flag | In Single Device Mode: asserts LOW when ≥256 words stored; in Depth Expansion: pulses to next device at last location |
| EF | Empty Flag | Open-drain output; goes LOW when read pointer = write pointer, blocking further reads |
| FF | Full Flag | Open-drain output; goes LOW when write pointer = (read pointer − 1), blocking further writes |
| VCC | Power Supply | 3.3 V nominal supply; decoupling required within 10 mm of pin per high-speed CMOS layout guidelines |
| GND | Ground Reference | Common return for all I/O and core logic; must be low-inductance plane-connected |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Dual-Port Operation | Independent W and R controls enable concurrent read/write without clock synchronization-critical for bridging mismatched data rates |
| Status Flag Logic | EF, FF, and HF flags provide real-time buffer occupancy feedback without software polling or address tracking |
| Auto-Retransmit Capability | Pulsing FL/RT LOW resets read pointer to origin while preserving write pointer-enables protocol-level message retransmission |
| Expandable Architecture | Supports unlimited depth expansion (daisy-chain via XI/XO) and width expansion (parallel devices) without external address logic |
| Low-Power CMOS Process | 180 mW max active power and 18 mW max power-down dissipation reduce thermal load in fanless enclosures |
Applications
| Industrial Data Acquisition | Telecom Line Card Buffering |
|---|---|
Use Scenario: High-speed analog-to-digital sampling in PLC modules where ADC output rate exceeds host MCU processing bandwidth. IC Role / Device Role / Timing Role: Asynchronous rate buffer isolating ADC clock domain (e.g., 10 MHz) from slower SPI-based MCU interface (e.g., 1 MHz). Use Value: Prevents sample loss during burst transfers; EF/FF flags enable deterministic DMA trigger points without CPU intervention. |
Use Scenario: Framing layer buffering in T1/E1 line cards handling HDLC or PPP encapsulation with variable packet lengths. IC Role / Device Role / Timing Role: First-in/first-out temporary storage between serial PHY and packet processor, absorbing jitter and slip events. Use Value: Eliminates need for complex SRAM + controller; 9-bit width accommodates 8-bit data + parity for error-checked transmission. |
| Multiprocessor Interconnect | Legacy System Interface Bridge |
Use Scenario: Shared-memory messaging between two independent microcontrollers running at different clocks in automotive body control units. IC Role / Device Role / Timing Role: Dual-port handshake buffer enabling non-blocking inter-processor communication with hardware flow control. Use Value: Reduces software overhead vs. software-managed queues; Half-Full flag allows early pre-fetch signaling to optimize throughput. |
Use Scenario: Adapting obsolete 5 V parallel peripherals (e.g., printers, scanners) to modern 3.3 V embedded hosts via level-shifting interface. IC Role / Device Role / Timing Role: Protocol-transparent data staging element that absorbs timing skew between legacy strobe-driven and synchronous host interfaces. Use Value: Maintains functional compatibility with IDT7201 family while reducing system power by 40% versus 5 V equivalents. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar FIFO memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 72V01L25JI | Same 512 × 9 organization and 25 ns speed grade, but in 32-pin PDIP package (through-hole) | Suitable for prototyping or legacy through-hole PCBs; lacks PLCC's thermal performance and rework flexibility | Select 72V01L25JI only for hand-soldered evaluation or repair of existing DIP-based systems |
| 72V02L25JGI8 | 1,024 × 9-bit depth (2× capacity), identical 25 ns timing, same PLCC package and pinout | Provides double buffer depth for longer burst tolerance; requires no PCB change but increases cost and power slightly | Choose 72V02L25JGI8 when application demands >512-word buffering margin without redesigning layout |
Compared with 72V01L25JGI8, 72V01L25JI offers mechanical compatibility with through-hole assembly but sacrifices thermal efficiency, while 72V02L25JGI8 delivers scalable depth with zero layout impact-making it the preferred upgrade path for capacity-constrained designs.

FAQ
What is the memory depth and data width of the 72V01L25JGI8?
The 72V01L25JGI8 provides a fixed 512 × 9-bit memory organization, totaling 4,608 bits. Its 9-bit data path supports 8-bit user data plus one parity or control bit-enabling error detection in serial communications and flexible protocol framing without external logic.
Does the 72V01L25JGI8 support industrial temperature operation?
Yes, the 72V01L25JGI8 is rated for –40°C to +85°C operation, meeting industrial temperature requirements. This rating is explicitly confirmed in the datasheet's "Commercial and Industrial Temperature Ranges" section and applies to the 25 ns speed grade as a standard offering.
What package type is used for the 72V01L25JGI8?
The 72V01L25JGI8 uses a 32-pin Plastic Leaded Chip Carrier (PLCC) with J32-1 footprint. This surface-mount package features gull-wing leads, an index corner, and JEDEC-compliant dimensions-optimized for automated placement and infrared reflow processes.
How does the Retransmit (RT) function operate on the 72V01L25JGI8?
When FL/RT is pulsed LOW in Single Device Mode (XI = GND), the 72V01L25JGI8 resets its internal read pointer to location zero while leaving the write pointer unchanged. This enables retransmission of buffered data from the beginning without clearing newly written entries-critical for retry-based protocols.
Is the 72V01L25JGI8 pin-compatible with older 5 V FIFOs like the IDT7201?
No, the 72V01L25JGI8 is functionally compatible but not pin-compatible with the 5 V IDT7201 family due to differing voltage tolerances and drive characteristics. While logic behavior and flag definitions match, direct replacement requires level-shifting and layout verification per Renesas' migration guidance.
