M29F040B-90N1 Description

Short technical summary and product information.

The STMicroelectronics M29F040B-90N1 is a 4 Megabit NOR Flash memory integrated circuit. It utilizes a parallel interface for data access and is housed in a 32-pin PLCC surface-mount package.

 

This non-volatile memory chip provides random access and erase/write capabilities, making it suitable for code storage in embedded systems. It supports rapid read/write cycles with a maximum access time of 45 nanoseconds and a write cycle time of 45ns per word/page.

 

The device operates within a supply voltage range of 4.5V to 5.5V and has an operating temperature range of 0°C to 70°C (TA). The memory is organized as 512K x 8 bits and uses NOR architecture for in-place read/write operations.

 

Designed for embedded systems, microcontroller-based designs, telecommunications, industrial controllers, and consumer electronics, the M29F040B-90N1 is ideal for applications requiring fast boot memory and in-system code updates.
