93LC66/P Description

Short technical summary and product information.

The Microchip Technology 93LC66/P is a 4Kbit serial Electrically Erasable PROM (EEPROM) designed for low-power nonvolatile memory applications. It operates from a single supply voltage ranging from 2.5V to 5.5V and features a Microwire serial interface.

 

This device supports memory configurations of 512 x 8 or 256 x 16 bits, selectable via the ORG pin. It operates at a clock frequency of up to 2 MHz and has a write cycle time of 10ms. The EEPROM is housed in an 8-pin PDIP package suitable for through-hole mounting.

 

Key features include self-timed erase and write cycles with automatic ERAL before WRAL, power on/off data protection circuitry, and a device status signal during erase/write cycles. It ensures 1,000,000 erase/write cycles and data retention exceeding 200 years. The operating temperature range is 0°C to 70°C (TA).

 

This component is ideal for applications requiring reliable, low-power nonvolatile data storage. Its robust design and standard packaging make it suitable for various embedded systems.
