Intel JS28F320C3BD90 32Mb 3V Flash Memory Chip: Datasheet and Technical Overview

The Intel JS28F320C3BD90 is a high-performance 32-megabit (4MB) 3-volt flash memory chip designed for embedded systems, telecommunications, networking equipment, and industrial applications. Manufactured using Intel's advanced multi-level cell (MLC) technology, this device offers a reliable non-volatile storage solution with robust performance and low power consumption.

A key feature of this memory chip is its 3.0-volt single power supply, which simplifies system design and reduces overall power requirements. Organized as 4,194,304 words of 8 bits each (32Mbit), it supports both uniform 64KB blocks and asymmetric sector architectures, providing flexibility for code and data storage. The device offers fast access times, with a 70ns maximum random access time, making it suitable for demanding applications where rapid data retrieval is critical.

The JS28F320C3BD90 incorporates the Advanced Boot Block architecture, which enhances system integration by allowing flexible placement of boot code. This architecture supports both top and bottom boot block configurations, enabling compatibility with various microprocessor and microcontroller requirements. The chip also features a Write State Machine (WSM) that automates program and erase operations, reducing software overhead and improving reliability.

With a 100,000 program/erase cycles per block endurance rating and a data retention capability of up to 20 years, this flash memory ensures long-term reliability. It supports common flash memory interfaces, including asynchronous read and write operations, and is compatible with the JEDEC standard command set. Additionally, the device includes hardware and software write protection mechanisms to prevent accidental data corruption.

Operating within an industrial temperature range (-40°C to +85°C), the Intel JS28F320C3BD90 is engineered for harsh environments. Its durability, combined with Intel's reputation for quality, makes it a preferred choice for critical applications.

ICGOODFIND: The Intel JS28F320C3BD90 stands out for its 3V operation, Advanced Boot Block architecture, and high endurance, making it ideal for embedded and industrial systems requiring reliable non-volatile memory.
