24AA014H/24LC014H 2 1K I C Serial EEPROM with Half-Array Write-Protect Device Selection Table Description: Part VCC Max. Temp. The Microchip Technology Inc. 24AA014H/24LC014H Number Range Clock Range is a 1Kbit Serial Electrically Erasable PROM with operation down to 1.7V. The device is organized as a (1) I 24AA014H 1.7V-5.5V 400 kHz single block of 128 x 8-bit memory with a 2-wire serial interface. Low-current design permits operation with 24LC014H 2.5V-5.5V 1 MHz I, E maximum standby and active currents of only 1 A and Note 1: 100 kHz for VCC < 1.8V 400 A, respectively. The device has a page write capability for up to 16 bytes of data. Functional address lines allow the connection of up to eight 24AA014H/ Features: 24LC014H devices on the same bus for up to 8 Kbits of Single-Supply with Operation down to 1.7V contiguous EEPROM memory. The device is available Low-Power CMOS Technology: in the standard 8-pin PDIP, 8-pin SOIC (150 mil), TSSOP, 2x3 TDFN and MSOP packages. - 400 A active current, maximum -1 A standby current, maximum (I-temp) Package Types Organized as a Single Block of 128 Bytes (128 x 8) PDIP, MSOP SOIC, TSSOP 2 2-Wire Serial Interface Bus, I C Compatible A0 1 8 VCC A0 1 8 VCC Schmitt Trigger Inputs for Noise Suppression A1 2 7 WP 2 7 A1 WP Output Slope Control to Eliminate Ground Bounce A2 3 6 SCL 3 6 A2 SCL 100 kHz and 400 kHz Compatibility VSS 4 5 SDA 4 5 1 MHz Compatibility (LC) VSS SDA Page Write Buffer for up to 16 Bytes TDFN Self-Timed Write Cycle (including Auto-Erase) Hardware Write Protection for Half Array 1 VCC A0 8 (40h-7Fh) 7 WP A1 2 Address Lines Allow up to Eight Devices on Bus 6 SCL A2 3 1 Million Erase/Write Cycles VSS 4 5 SDA ESD Protection > 4,000V Data Retention > 200 Years Block Diagram Factory Programming (QTP) Available Pb-Free and RoHS Compliant WP A0 A1 A2 HV Generator 8-pin PDIP, SOIC, TSSOP, TDFN and MSOP Packages I/O Memory Available for Extended Temperature Ranges: Control Control EEPROM Logic - Industrial (I): -40C to +85C XDEC Logic Array - Automotive (E): -40C to +125C SDA SCL Write-Protect Circuitry VCC YDEC VSS Sense Amp.
