The AM26C31IDBR is a high-performance, 8-bit, microprocessor-compatible, CMOS serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Texas Instruments. It is designed to provide reliable and non-volatile data storage for various applications. Here's a brief description, features, and applications of the AM26C31IDBR:

Description:

The AM26C31IDBR is a serial EEPROM with a memory capacity of 2,048 bits (256 x 8 bits) organized as 32 pages of 64 bytes each. It features a standard SPI (Serial Peripheral Interface) compatible interface, allowing for easy integration with microcontrollers and other SPI-compatible devices. The device operates over a wide supply voltage range of 2.7V to 5.5V and has a fast read cycle time of 70 ns (typical) with a 10 MHz SPI clock.

Features:

1. Memory Capacity: 2,048 bits (256 x 8 bits) organized in 32 pages of 64 bytes each.
2. Standard SPI-compatible interface for easy integration with microcontrollers.
3. Wide supply voltage range: 2.7V to 5.5V.
4. Fast read cycle time: 70 ns (typical) with a 10 MHz SPI clock.
5. Page Write mode: Allows for byte or page write operations.
6. Block Erase mode: Allows for erasing a 64-byte page at a time.
7. Software/Hardware selectable write protection for data protection.
8. Low power consumption: Active mode (Typ. 1 mA) and Standby mode (Typ. 1 µA).
9. Operating temperature range: -40°C to +85°C (Industrial) and -40°C to +125°C (Extended Industrial).
10. Small package options available: SOIC, TSSOP, and DFN.
