Microchip 1 kB Serial EEPROM 200 ns 8-Pin PDIP Microwire 93C46B/P

Microchip 93C46B/P is a 1 kB serial EEPROM designed for industrial and electronic applications requiring reliable non-volatile memory storage. Featuring a 64 x 16-bit organisation and a fast access time of 200 ns, this EEPROM enables efficient serial data transfer via the Microwire interface.

This device is built into an 8-Pin PDIP package for easy through-hole mounting on printed circuit boards. It maintains operation over a broad supply voltage range from 4.5V up to 5.5V and sustains functionality within harsh operating temperatures from -40°C to 85°C, suitable for automotive and industrial environments.

Key features include self-timed erase and write cycles with auto-erase before write, power-on/off data protection circuitry, a device status signal for read/write readiness, and sequential read functions. The EEPROM supports up to 1 million erase/write cycles and ensures data retention exceeding 200 years, making it highly durable for long-term applications.

Compact physical dimensions (9.4mm x 6.35mm x 3.3mm) facilitate integration into space-constrained electronic assemblies. The device's 2 MHz maximum clock frequency optimizes data throughput for demanding industrial and laboratory equipment, HVAC systems, embedded controls, and manufacturing automation.
