93LC46-I/P Description

Short technical summary and product information.

The Microchip Technology 93LC46/56/66 series, including the 93LC46-I/P, are 1K, 2K, and 4K low voltage serial Electrically Erasable PROMs (EEPROM). These devices utilize advanced CMOS technology, making them suitable for low-power nonvolatile memory applications. The 93LC46-I/P specifically offers 1Kbit of memory capacity, configurable as 128 x 8 or 64 x 16 bits via the ORG pin.

 

Key electrical characteristics include a wide operating voltage range of 2.5V to 5.5V and a clock frequency of up to 2 MHz. Power consumption is minimal, with a typical active read current of 100 µA and a standby current of 3 µA at 2.5V. The device ensures data integrity with 1,000,000 erase/write cycles and data retention exceeding 200 years.

 

This EEPROM is designed for easy integration, featuring an industry-standard 3-wire serial I/O (Microwire) interface. It supports self-timed erase and write cycles with automatic ERAL before WRAL, along with power on/off data protection circuitry. The 93LC46-I/P is housed in an 8-pin PDIP package, suitable for through-hole mounting, and operates within an industrial temperature range of -40°C to +85°C.
