Memory IC datasheet and documents for JS28F640J3F75A

JS28F640J3F75A

Memory IC Overview

The JS28F640J3F75A is a 64 Mbit NOR Flash memory device manufactured by Alliance Memory, Inc. It features a parallel asynchronous interface with an access time of 75 ns. The component supports dual data bus widths of 8-bit and 16-bit, organized as 8M x 8 or 4M x 16. It operates within a voltage range of 2.7 V to 3.6 V and includes an active read current maximum of 70 mA. The device is housed in a 56-pin TSOP package and is rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

Supports flexible 8-bit and 16-bit data bus configurations for system compatibility
Provides fast asynchronous random access performance suitable for code execution
Operates on a single low-voltage power supply for efficient energy usage

Memory IC Applications

Embedded systems requiring direct code execution (XIP)
Industrial control hardware storage
Consumer electronics firmware retention

Memory IC Procurement Notes

Verify the manufacturer origin carefully, as this part number appears under both Micron Technology and Alliance Memory branding in public databases due to historical corporate acquisitions. Confirm the specific datasheet revision and pinout compatibility with your design before procurement. Ensure the ordering suffix matches the required speed grade and package variant exactly.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with 75 ns access speed is required in a TSOP-56 form factor. It is appropriate for designs needing simultaneous 8-bit and 16-bit bus flexibility. Consider the -40°C to +85°C operating range for industrial environments. Verify that the 3.6 V maximum voltage aligns with the target system's power rails.

Memory IC Part Context

This part belongs to the J3 series of NOR Flash memories. The series is characterized by high reliability and support for standard flash commands. The 64 Mbit density positions it between smaller 32 Mbit and larger 128 Mbit variants like the JS28F128J3F75A, offering a balance of storage and speed for mid-range embedded applications.
