24XX32X 24XX32 24AA32A/24LC32A 2 32K I C Serial EEPROM Device Selection Table Description The Microchip Technology Inc. 24AA32A/24LC32A Part VCC Max Clock Temp (24XX32A*) is a 32 Kbit Electrically Erasable PROM. Number Range Frequency Ranges The device is organized as four blocks of 8K x 8-bit (1) 24AA32A 1.8-5.5 400 kHz I memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.8V, with standby 24LC32A 2.5-5.5 400 kHz I, E and active currents of only 1 A and 1mA, Note 1: 100 kHz for VCC <2.5V 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 capability for up to 32 bytes of data. Functional address Single supply with operation down to 1.8V lines allow up to eight devices on the same bus, for up Low-power CMOS technology to 256 Kbits address space. The 24XX32A is available - 1 mA active current typical in the standard 8-pin PDIP, surface mount SOIC, -1 A standby current (max.) (I-temp) TSSOP and MSOP packages.
