Product details
Overview
72V06L25JGI from Renesas Electronics (formerly IDT) is a 3.3 V CMOS asynchronous FIFO memory with 16,384 × 9-bit depth and width, supporting simultaneous read/write operations in multiprocessing and rate-buffering systems. It features 15 ns access time, industrial temperature range (–40°C to +85°C), 32-pin PLCC package, and status flags (Empty, Full, Half-Full) for overflow/underflow protection.
For engineers reviewing the 72V06L25JGI datasheet, 72V06L25JGI pinout, 72V06L25JGI application, or 72V06L25JGI equivalent, this device serves as a drop-in upgrade path from legacy 5 V 7206 FIFOs while enabling low-power, high-reliability buffering in serial communication interfaces, data acquisition front-ends, and real-time protocol bridges where deterministic latency and flag-controlled handshaking are critical.
Technical Context
The 72V06L25JGI implements dual-port asynchronous FIFO architecture using ring-pointer logic-no external address bus required-and supports auto-retransmit via FL/RT pin to reset read pointer without affecting write pointer. Its 9-bit data path accommodates parity or control bits, making it suitable for error-checked data links.
It operates across 3.0–3.6 V supply, delivers 25 ns access time (tA), and maintains functional compatibility with the 720x family while reducing active power to ≤60 mA (ICC1) and standby current to ≤5 mA (ICC2). The device supports single-device, width-expansion, and depth-expansion modes via XI/XO daisy-chaining.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Depth × Width | 16,384 × 9 bits - supports large burst buffering without external addressing logic |

Pinout & Package
72V06L25JGI is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC, J32-1) package with standard footprint and lead finish (SnPb, EOL per PDN# SP-17-02).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D8 | Data Input Bus | 9-bit parallel input path; accepts data on falling edge of W |
| Q0–Q8 | Data Output Bus | 9-bit tristate output; driven only during active R cycle |
| W | Write Enable | Falling-edge triggered write; blocked when FF = LOW to prevent overflow |
| R | Read Enable | Falling-edge triggered read; blocked when EF = LOW to prevent underflow |
| RS | Reset | Active-Low synchronous reset of both read/write pointers to location zero |
| FL/RT | First Load / Retransmit | In single-device mode: retransmit trigger; in depth expansion: first-load indicator |
| XI | Expansion In | GND = single-device mode; tied to XO of prior device in daisy-chain configuration |
| XO/HF | Expansion Out / Half-Full Flag | Single-device: HF output; depth expansion: pulse signal to next device at memory wrap |
| FF | Full Flag | Active-Low; asserts when write pointer = read pointer – 1 (full condition) |
| EF | Empty Flag | Active-Low; asserts when read pointer = write pointer (empty condition) |
| VCC | Power Supply | 3.3 V nominal supply; decoupling required per high-speed CMOS layout guidelines |
| GND | Ground | Reference plane for all I/O and internal logic; separate analog/digital grounding not required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FIFO memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 72V06L15JGI | 15 ns access time (vs. 25 ns); higher ICC1 (75 mA max) and fS (40 MHz) | Better suited for ultra-low-latency control loops where <15 ns tA is mandatory | Select when system timing budget requires tighter access window; verify thermal margin due to higher power draw |
| 72V06L35JGI | 35 ns access time (vs. 25 ns); lower ICC1 (60 mA max) and fS (22.2 MHz) | Optimized for cost-sensitive industrial designs where 35 ns tA meets timing slack | Select when board space and BOM cost outweigh marginal speed gain; same pinout and flag behavior |
Compared with 72V06L25JGI, the L15 variant trades higher power for faster response in time-critical control, while the L35 variant reduces cost and power at the expense of latency headroom-both retain identical pinout, flag logic, and expansion capability.

FAQ
What is the memory organization of the 72V06L25JGI?
The 72V06L25JGI implements a 16,384 × 9-bit asynchronous FIFO structure, meaning it holds up to 16,384 words of 9-bit data. This organization supports parity bit insertion or control signaling alongside 8-bit payload data, and is confirmed in the IDT72V06 datasheet section "DESCRIPTION" and ordering information table. The 72V06L25JGI uses ring-pointer addressing internally-no external address lines are needed.
Does the 72V06L25JGI support industrial temperature operation?
Yes, the 72V06L25JGI is rated for industrial temperature range (–40°C to +85°C), as explicitly stated in the "COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES" header and confirmed in the DC Electrical Characteristics table footnote: "Industrial temperature range product for the 25ns speed grade is available as a standard device." This makes the 72V06L25JGI suitable for deployment in factory automation, motor drives, and outdoor instrumentation.
What package type does the 72V06L25JGI use?
The 72V06L25JGI uses a 32-pin Plastic Leaded Chip Carrier (PLCC) package, designated J32-1 in the ordering information. This is verified in the PIN CONFIGURATION diagram (page 2), the "ORDERING INFORMATION" table (where 'J' = PLCC), and the absolute maximum ratings section listing PLCC-specific mechanical dimensions. The part suffix 'JGI' confirms this package variant.
Can the 72V06L25JGI be used in depth-expansion configurations?
Yes, the 72V06L25JGI supports depth expansion via its XI (Expansion In) and XO/HF (Expansion Out) pins, as detailed in the "OPERATING MODES" section and Figure 14. In depth-expansion mode, multiple 72V06L25JGI devices are daisy-chained to increase total word depth, with external logic required to OR composite EF and FF signals. Note that HF and RT functions are disabled in this mode.
Is the 72V06L25JGI pin-compatible with older 5 V FIFOs?
The 72V06L25JGI is functionally compatible with the 720x family (e.g., 7206), but not pin-compatible due to voltage-level differences: the 72V06L25JGI operates at 3.3 V and requires 3.3 V logic levels, whereas the 7206 uses 5 V. Direct replacement would require level-shifting or redesign. The datasheet states "Functionally compatible with 720x family", not pin-compatible-this distinction is critical for migration planning.
