Packaging

Type: 132-BQFP bumpered (Supplier Device Package: 132-BQFP, 24.13 x 24.13 mm)

Material: Molded plastic, gull-wing leads

Size: 24.13 mm x 24.13 mm body; 132 pins

Mounting: Surface mount (SMT), tray packaging

Pin configuration: 36-bit data I/O with separate read/write controls, clocks, status flag pins, and expansion interface (depth/width)

Thermal characteristics: Commercial grade (0°C to 70°C); use standard SMT reflow profile and ensure adequate airflow for sustained high-speed operation

Electrical properties: 3.0–3.6 V supply, 100 MHz data rate, 7.5 ns access time, bi-directional bus, programmable flags, retransmit; Max supply current listed as 350A (this value appears atypical—verify against the datasheet)

Compliance: RoHS non-compliant

Lifecycle

Status: Mature product; availability can vary by region due to RoHS non-compliance. No confirmed EOL notice in our current records.

Direct TI pin-for-pin replacements: Not confirmed.

Equivalent/alternative models: Exact pin-compatible matches are not confirmed. Similar 3.3 V synchronous FIFO families exist in the market (Renesas/IDT and Infineon/Cypress), but pinouts, timing, and features differ. For a correct, risk-free cross, contact our sales team.

Action: For the most suitable alternatives and up-to-date lifecycle info, please contact our sales team via the Y-IC website. We will propose drop-in or near-drop-in options based on your board constraints, speed, and compliance needs.

Key Application Areas

High-speed data buffering between mismatched clock domains

DSP/FPGA/MCU interfacing and pipeline decoupling

Telecom and networking line cards (packet buffering, rate adaptation)

Video/audio streaming buffers and frame/line FIFOs

Bus bridging and protocol conversion

Industrial control systems needing deterministic data queues
