Microchip 93C46B-I/SN 1Kbit Serial EEPROM SOIC-8 Package

The Microchip 93C46B-I/SN 1Kbit Serial EEPROM is a 1 kilobit (1Kbit) serial Electrically Erasable Programmable Read-Only Memory designed for non-volatile data storage in a compact SOIC-8 surface-mount package.

Overview

Utilising CMOS technology, this device is designed for applications that require low power consumption. It is compatible with the MICROWIRE serial interface, providing a simple three-wire connection for communication with microcontrollers and other logic devices. The memory is organised as 64 words by 16 bits and supports a maximum clock frequency of 3 MHz.

Key Features

• Self-timed erase and write cycles, which simplify programming
• Automatic 'erase all' (ERAL) function that precedes a 'write all' (WRAL) operation for batch programming
• Built-in power-on and power-off data protection circuitry to help safeguard stored information during voltage transitions
• Ready/busy status signal, allowing the host system to manage write operations
• Sequential read operation for faster data access
• Rated for 1,000,000 erase/write cycles
• Data retention specified for over 200 years
• Low-power CMOS technology suitable for battery-powered and energy-sensitive devices
• Compact SOIC-8 surface-mount package designed for automated PCB assembly
• Industrial temperature range
