24AA32A/24LC32A 2 32K I C Serial EEPROM Device Selection Table Description: Part VCC Max. Clock Temp. The Microchip Technology Inc. 24AA32A/24LC32A Number Range Frequency Ranges (24XX32A*) is a 32 Kbit Electrically Erasable PROM. The device is organized as a single block of 4K x 8-bit (1) 24AA32A 1.7-5.5 400 kHz I memory with a 2-wire serial interface. Low-voltage 24LC32A 2.5-5.5 400 kHz I, E design permits operation down to 1.7V, with standby Note 1: 100 kHz for VCC <2.5V. and active currents of only 1 A and 1 mA, respectively. It has been developed for advanced, low- power applications such as personal communications Features: or data acquisition. The 24XX32A also has a page write Single Supply with Operation down to 1.7V for capability for up to 32 bytes of data. Functional address 24AA32A Devices, 2.5V for 24LC32A Devices lines allow up to eight devices on the same bus, for up to 256 Kbits address space. The 24XX32A is available Low-Power CMOS Technology: in the standard 8-pin PDIP, surface mount SOIC, SOIJ, - Active current 1 mA, typical TSSOP, DFN, TDFN and MSOP packages. The - Standby current 1 A, typical 24XX32A is also available in the 5-lead SOT-23 and 2 2-Wire Serial Interface, I C Compatible Chip Scale packages.
