93LC66A/P Description

Short technical summary and product information.

The Microchip Technology 93LC66A/P is a 4Kbit serial Electrically Erasable PROM (EEPROM) designed for low-power, nonvolatile memory applications. It utilizes advanced CMOS technology and features an industry-standard 3-wire serial I/O interface compatible with Microwire protocol. The device operates over a wide voltage range of 2.5V to 5.5V and supports a clock frequency of up to 2 MHz.

 

This EEPROM has a memory organization of 512 x 8 bits and a memory size of 4Kbit. It offers features such as self-timed erase/write cycles, power-on/off data protection circuitry, and a device status signal (Ready/Busy). The 93LC66A/P is rated for an operating temperature range of 0°C to 70°C (TA).

 

The component is available in an 8-DIP (0.300", 7.62mm) package, suitable for through-hole mounting. Its write cycle time is 6ms. The device is designed for reliability with data retention exceeding 200 years and 1,000,000 erase/write cycles.
