24AA01/24LC01B 1K I2C™ Serial EEPROM Device Selection Table Part Number 24AA01 24LC01B Note 1: VCC Range 1.7-5.5 2.5-5.5 Max. Clock Frequency 400 kHz(1) 400 kHz Temp. Ranges I I, E Description: The Microchip Technology Inc. 24AA01/24LC01B (24XX01*) is a 1 Kbit Electrically Erasable PROM. The device is organized as one block of 128 x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.7V with standby and active currents of only 1 μA and 1 mA, respectively. The 24XX01 also has a page write capability for up to 8 bytes of data. The 24XX01 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 DFN and MSOP packages, and is also available in the 5-lead SOT-23 package. 100 kHz for VCC 4,000V • More than 1 million erase/write cycles • Data retention >200 years • Factory programmable available • Packages include 8-lead PDIP, SOIC, TSSOP, DFN, MSOP and 5-lead SOT-23 • Pb-free and RoHS compliant • Temperature ranges: - Industrial (I): -40°C to +85°C - Automotive (E): -40°C to +125°C Package Types PDIP, MSOP A0 A1 A2 VSS 1 2 3 4 SOT-23-5 SCL Vss SDA Note: 1 2 3 4 Vcc 5 WP A0 1 A1 2 A2 3 VSS 4 8 7 6 5 VCC WP SCL A0 A1 A2 SOIC, TSSOP 1 2 3 4 DFN 8 VCC 7 WP 6 SCL 5 SDA 8 7 6 5 VCC WP SCL SDA SDA VSS Pins A0, A1 and A2 are not used by the 24XX01 (no internal connections).
