24LC21A/P Description

Short technical summary and product information.

The Microchip Technology 24LC21A/P is a 1Kbit dual-mode Electrically Erasable PROM (EEPROM) designed for serial transmission of configuration and control information. It operates with a single supply voltage ranging from 2.5V to 5.5V and utilizes the I2C compatible 2-wire serial interface bus.

 

This device supports a clock frequency of 400 kHz and has an access time of 900 ns. The memory organization is 128 x 8 bits, with a page write buffer supporting up to eight bytes. It ensures 1,000,000 erase/write cycles and offers data retention exceeding 200 years. The EEPROM operates within an industrial temperature range of -40°C to 85°C.

 

Packaged in an 8-pin PDIP, the 24LC21A/P is suitable for through-hole mounting. It features low-power CMOS technology with a typical active current of 1 mA and a standby current of 10 μA at 5.5V. ESD protection is rated at over 4000V.
