Product details
Overview
72V03L25JGI8 from Renesas Electronics (formerly IDT) is a 3.3 V CMOS asynchronous FIFO memory with 2,048 × 9-bit depth and width, supporting simultaneous independent read/write operations, 25 ns access time, industrial temperature range (–40°C to +85°C), and status flags (Empty, Full, Half-Full) for data flow control in rate-mismatch buffering applications.
For engineers reviewing the 72V03L25JGI8 datasheet, 72V03L25JGI8 pinout, 72V03L25JGI8 application, or 72V03L25JGI8 equivalent, this device serves as a low-power, pin-compatible upgrade path from legacy 5 V FIFOs in industrial communications, multiprocessing interfaces, and protocol bridging where deterministic latency and flag-driven handshaking are required.
Technical Context
The 72V03L25JGI8 implements a dual-port ring-buffer architecture using high-speed CMOS, with independent write and read pointers managed entirely internally-no external address bus or control sequencing required. It supports single-device mode (with XI grounded) and depth/width expansion via XO/HF and FL/RT pins.
Its asynchronous operation enables seamless interfacing between clock domains; the 9-bit data path accommodates parity or control bits, and the auto-retransmit (RT) function resets the read pointer without affecting write state-critical for re-sending burst data after error detection in serial protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2,048 × 9-bit (18,432 bits total); supports 9-bit data words with optional parity/control bit handling. |
| Access Time (tA) | 25 ns max; guarantees deterministic read latency for real-time buffering in industrial controllers. |
| Supply Voltage | 3.0 V to 3.6 V; compatible with modern 3.3 V logic families and reduces power vs. legacy 5 V FIFOs. |
| Power Consumption | Active: ≤60 mA (≤198 mW at 3.3 V); Power-down: ≤5 mA (≤16.5 mW); enables low-idle-state system design. |
| Operating Temperature | –40°C to +85°C (industrial grade); validated for deployment in factory automation and outdoor telecom equipment. |
| Status Flags | EF (Empty), FF (Full), XO/HF (Half-Full or Expansion Out); enables hardware handshaking without software polling. |
| Retransmit Function | RT pulse resets read pointer to start-of-buffer; preserves write pointer state-essential for repeatable packet retransmission. |
Pinout & Package
72V03L25JGI8 is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC, J32-1) package with standard lead finish (SnPb), compliant with industrial thermal cycling requirements and surface-mount assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D8 | Data Input Bus | 9-bit parallel input path; accepts data on falling edge of W; supports parity or control bit insertion. |
| Q0–Q8 | Data Output Bus | 9-bit three-state output; driven only during active read (R = LOW); high-Z when R = HIGH. |
| W | Write Enable | Falling-edge-triggered write strobe; initiates storage into next sequential location if FF = HIGH. |
| R | Read Enable | Falling-edge-triggered read strobe; outputs next sequential word if EF = HIGH; blocks reads when EF = LOW. |
| RS | Reset | Active-LOW synchronous reset; forces both read/write pointers to location zero; required before first write. |
| FL/RT | First Load / Retransmit | In single-device mode (XI = GND): RT input; pulse LOW to reset read pointer to start without affecting write pointer. |
| XI | Expansion In | Grounded for single-device mode; tied to XO of prior device in depth-expansion daisy chain. |
| XO/HF | Expansion Out / Half-Full Flag | In single-device mode: HF output goes LOW when ≥1,024 words stored; in expansion mode: signals end-of-buffer to next device. |
| EF | Empty Flag | Open-drain output; LOW indicates no valid data available for read; used to gate R strobes in hardware handshaking. |
| FF | Full Flag | Open-drain output; LOW indicates no space for new write; used to gate W strobes to prevent overflow. |
| VCC, GND | Power Supply | 3.3 V supply (3.0–3.6 V) and ground; decoupling required per high-speed CMOS layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Asynchronous Dual-Port Operation | Independent read/write clocks not required; eliminates clock-domain crossing logic and simplifies interface design. |
| Hardware Flow Control Flags | EF, FF, and HF provide real-time buffer status without CPU intervention-reducing firmware overhead in embedded systems. |
| Retransmit Capability | RT pulse restores read pointer to origin while preserving write position-enables deterministic retransmission in UART/RS-485 protocols. |
| Expandable Architecture | Supports unlimited depth expansion (daisy-chain via XI/XO) and width expansion (parallel devices)-scalable from 2K×9 to multi-Mbit buffers. |
| Industrial Temperature Rating | Qualified from –40°C to +85°C; meets reliability requirements for industrial PLCs, motor drives, and base station backplanes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar FIFO memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 72V03L15JGI8 | 15 ns access time (vs. 25 ns); higher ICC1 (75 mA max vs. 60 mA); same package and pinout. | Suitable for tighter timing budgets in high-throughput data acquisition; requires additional power budgeting. | Select when system timing margin demands sub-25 ns latency and power increase is acceptable. |
| 72V03L25PGI8 | Same speed grade and organization, but in 32-pin PDIP (plastic DIP) instead of PLCC. | Used in through-hole prototyping or legacy board repair; incompatible with surface-mount production lines. | Choose only for manual assembly, lab validation, or backward-compatible DIP socket replacement. |
Compared with 72V03L25JGI8, the 15 ns variant trades higher power for lower latency, while the PDIP version sacrifices surface-mount compatibility for mechanical interchangeability in legacy systems-neither offers pin-to-pin or functional drop-in replacement without layout or thermal review.

The 72V03L25JGI8 provides a 2,048-word deep × 9-bit wide memory array (18,432 bits total). This configuration supports 9-bit parallel data paths, allowing one bit to be reserved for parity or control signaling-commonly used in industrial serial communication and protocol bridging applications where error detection is essential.
Does the 72V03L25JGI8 support industrial temperature operation?
Yes, the 72V03L25JGI8 is qualified for industrial temperature operation from –40°C to +85°C. This rating is explicitly specified in the datasheet's DC Electrical Characteristics table and applies to the 25 ns speed grade as a standard offering-making it suitable for deployment in factory automation, motor control, and outdoor telecom infrastructure.
What is the purpose of the FL/RT pin on the 72V03L25JGI8?
On the 72V03L25JGI8, the FL/RT pin serves dual functions depending on configuration: when Expansion In (XI) is grounded (single-device mode), it acts as Retransmit (RT), resetting the read pointer to location zero upon a LOW pulse while preserving the write pointer position. In depth-expansion mode, it functions as First Load (FL) to designate the initial device in a daisy chain.
Can the 72V03L25JGI8 be used in width-expansion configurations?
Yes, the 72V03L25JGI8 supports width expansion by connecting multiple devices in parallel with shared control signals (W, R, RS). For example, two 72V03L25JGI8 units can form a 2,048 × 18-bit FIFO. Status flags (EF, FF, HF) remain valid from any one device, simplifying monitoring in wide-bus systems such as video frame buffering or multi-channel data acquisition.
