Detailed Description

4Mbit (512K x 8) asynchronous CMOS SRAM

3.0 V to 3.6 V supply, 15 ns access time, 15 ns write cycle

Parallel interface, commercial operating range 0°C to 70°C (TA)

Package: 44‑lead TSOP II, shipped in tubes

RoHS status: non-compliant (leaded finish)

Base product number: IDT71V424

Key Features

4Mbit capacity organized as 512K x 8

3.3 V nominal operation (3.0 V to 3.6 V)

Fast 15 ns read access

15 ns write cycle time

Asynchronous SRAM, simple parallel interface

Surface-mount TSOP II 44-lead package

Commercial temperature range 0°C to 70°C

Volatile memory (data lost when power is removed)

Key Advantages

Low latency and deterministic timing for time-critical tasks

Simple interface (address, data, and control signals) reduces design effort

Mature, widely used architecture with broad ecosystem support

Compact TSOP II footprint saves PCB space

Ideal drop-in for legacy 3.3 V SRAM designs needing 15 ns speed

Stable performance across commercial temperature range

Packaging

Type: 44‑lead TSOP II (Thin Small Outline Package, Type II)

Material: molded epoxy plastic body, gull‑wing leads

Size: body width 0.400 inch (10.16 mm). Refer to datasheet for full mechanical drawing and height/length.

Mounting: surface mount

Pin configuration (typical for 512K x 8 SRAM): address pins (A0–A18), data I/O (DQ0–DQ7), control pins (CE, OE, WE), power pins (VCC, VSS). Verify exact pinout in the datasheet.

Thermal characteristics: commercial operating temperature 0°C to 70°C (TA). Use good PCB layout for heat spreading.

Electrical properties: 3.0–3.6 V supply, LVTTL/CMOS‑compatible interface, 15 ns read/write timing. See datasheet for currents and detailed AC/DC specs.

Supplier device package: 44‑TSOP II

Shipment packaging: Tube

RoHS: non‑compliant

Lifecycle

Current lifecycle may vary by region and finish due to RoHS status. Availability can be limited for older leaded variants. Contact Y-IC for up-to-date status.
