Microchip 4 kB Serial EEPROM 200 ns 2 MHz 8-Pin SOIC Serial-Microwire 93LC66B-I/SN

Microchip 93LC66B-I/SN is a 4 kB Serial EEPROM designed for reliable and efficient non-volatile memory storage. Featuring a fast 200 ns maximum random access time and a 2 MHz maximum clock frequency, this EEPROM operates using the Serial-Microwire interface protocol on a compact 8-pin SOIC surface-mount package. Its 256 x 16 bit organisation provides 4 kB of memory capacity suitable for a variety of embedded applications.

Operating voltage ranges from 2.5 V minimum to 5.5 V maximum, accommodating flexible power supply environments. The device guarantees data retention exceeding 200 years and supports up to 1,000,000 erase/write cycles, offering long-term durability and endurance for industrial and consumer electronics. Its operating temperature range from -40°C to 85°C makes it suitable for harsh environmental conditions.

Key features include self-timed erase and write cycles with auto-erase before write capability, power-on/off data protection circuitry to prevent data corruption during power fluctuations, and sequential read functionality for efficient data access. The device’s low supply current of 2 mA ensures suitability for power-sensitive electronic systems.
