MICROCHIP 93C46 1Kbit Serial EEPROM SOIC8

The MICROCHIP 93C46B/SN is a 1 kilobit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for compatibility with the MICROWIRE serial interface. This advanced, non-volatile memory solution utilises low-power CMOS technology, making it an ideal choice for applications where reliable data storage with minimal power consumption is critical.

A key feature is its flexible architecture, capable of operating in either an 8-bit or 16-bit word organisation. Word-selectable devices like the 93AA46C, 93LC46C, or 93C46C depend on external logic levels applied to the ORG pin to configure the word size, while the 93C46B variant provides a dedicated 16-bit communication interface.

Robust Features for Reliable Operation

Engineered for endurance and data integrity, this EEPROM offers a remarkable one million erase/write cycles and boasts a data retention period exceeding 200 years. It incorporates sophisticated protection circuitry to safeguard data during power transitions. The device supports sequential read operations for efficient data access and provides a clear ready/busy status signal to indicate its operational state.

The self-timed erase and write cycles simplify the programming process, while dedicated commands for 'Erase All' (ERAL) and 'Write All' (WRAL) allow for bulk memory management. Communication is handled via a compact, industry-standard 3-wire serial I/O interface, supporting clock frequencies up to 3 MHz.

Technical Specifications

This surface-mount device is supplied in an 8-pin SOIC package, designed for straightforward integration into modern electronic assemblies. It operates from a single 5V supply, with a voltage range from 4.5V to 5.5V, and is specified for a commercial operating temperature range of 0°C to 70°C.

With its combination of high reliability, low power consumption, and industry-standard interfacing, the MICROCHIP 93C46 is a trusted
