24C01CT-E/ST Microchip

24C01C 2 1K 5.0V I C Serial EEPROM Features: Description: Single Supply with Operation from 4.5V to 5.5V The Microchip Technology Inc. 24C01C is a 1K bit Serial Electrically Erasable PROM with a voltage range Low-Power CMOS Technology: of 4.5V to 5.5V. The device is organized as a single - Read current 1 mA, max. block of 128x8-bit memory with a 2-wire serial - Standby current 5 A, max. interface. Low-current design permits operation with 2 2-Wire Serial Interface, I C 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 times of only 1 ms for both byte and page writes. Func- Output Slope Control to Eliminate Ground Bounce 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 packages. The 24C01C is also available in the 6-lead ESD Protection >4000V SOT-23 package. More than 1 Million Erase/Write Cycles Data Retention >200 Years Block Diagram Factory Programming Available Packages include 8-lead PDIP, SOIC, TSSOP, A0 A1 A2 DFN, TDFN, MSOP and 6-lead SOT-23 HV Generator Pb-Free and RoHS Compliant Temperature Ranges: I/O Memory Control - Industrial (I): -40 C to +85C Control EEPROM Logic Logic XDEC - Automotive (E): -40 C to +125 C Array SDA SCL VCC YDEC VSS Sense Amp.
