24C01C 1K 5.0V I2C™ Serial EEPROM Features: Description:
• Single Supply with Operation from 4.5V to 5.5V The Microchip Technology Inc. 24C01C is a 1K bit • Low-Power CMOS Technology: Serial Electrically Erasable PROM with a voltage range - Read current 1 mA, max. of 4.5V to 5.5V. The device is organized as a single block of 128 x 8-bit memory with a 2-wire serial - Standby current 5 A, max. interface. Low-current design permits operation with • 2-Wire Serial Interface, I2C™ Compatible max. standby and active currents of only 5 A and 1 • Cascadable up to Eight Devices mA, respectively. The device has a page write capabil- • Schmitt Trigger Inputs for Noise Suppression ity for up to 16 bytes of data and has fast write cycle • Output Slope Control to Eliminate Ground Bounce times of only 1 ms for both byte and page writes. Func- tional address lines allow the connection of up to eight • 100 kHz and 400 kHz Clock Compatibility 24C01C devices on the same bus for up to 8K bits of • Page Write Time 1 ms max. contiguous EEPROM memory. The device is available • Self-Timed Erase/Write Cycle in the standard 8-pin PDIP, 8-pin SOIC (3.90 mm), • 16-Byte Page Write Buffer 8-pin 2x3 DFN and TDFN, 8-pin MSOP and TSSOP • ESD Protection >4000V packages. The 24C01C is also available in the 6-lead • More than 1 Million Erase/Write Cycles SOT-23 package. • Data Retention >200 Years
