Key Advantages

High throughput at 3.3 V with simple, predictable timing

Flexible scaling using depth/width expansion to meet larger buffer needs

Clear status via programmable flags simplifies flow control

Bi-directional design reduces glue logic and eases system interfacing

Retransmit helps with error recovery and data re-read

Mature TI logic family with broad ecosystem and design references

Packaging

Type: 120-HLQFP (LQFP), surface-mount

Body size: 14 x 14 mm nominal

Pin count: 120 leads; typical fine-pitch (refer to datasheet for exact pitch)

Finish/material: Leadframe with epoxy mold compound; non-RoHS (leaded finish)

Height/profile: Low-profile QFP form factor (see datasheet for exact Z-height)

Pin configuration: 36-bit data bus pins, control pins (clock, write/read enables, reset), programmable flag pins, and expansion interface pins for width/depth scaling

Thermal characteristics: No exposed thermal pad; designed for ambient 0°C–70°C operation; thermal resistance values depend on PCB and airflow (see datasheet for exact ThetaJA/ThetaJC)

Electrical properties: 3.0–3.6 V supply, 50 MHz operation, 11.5 ns access time, max supply current listed as 350A in provided spec (verify exact current in the datasheet), bi-directional bus behavior

Lifecycle

Status: Mature device family. Availability can vary by region and compliance requirements due to non-RoHS finish.

Nearing discontinuation: Not explicitly flagged in the provided data; check current stock and lead times.

Equivalent/alternative models to evaluate (verify pin compatibility, timing, and package before use):

- Renesas/IDT 72V362 (512 x 36, 3.3 V synchronous FIFO family)

- Renesas/IDT 72V361 (256 x 36, 3.3 V synchronous FIFO; lower depth alternative)

- Infineon (Cypress legacy) CY7C4366x/4363x families (3.3 V synchronous FIFO, x36 width variants)

If you need a pin-to-pin or drop-in equivalent, or RoHS-compliant alternatives, please contact our sales team via the Y-IC website for a detailed cross-reference and availability.
