24AA32AF/24LC32AF 2 32K I C Serial EEPROM with Quarter-Array Write-Protect Device Selection Table Description: Part VCC Max. Clock Temp. The Microchip Technology Inc. 24AA32AF/24LC32AF Number Range Frequency Ranges (24XX32AF*) is a 32 Kbit Electrically Erasable PROM. The device is organized as a single block of 4K x 8-bit (1) 24AA32AF 1.7-5.5 400 kHz I memory with a 2-wire serial interface. Low-voltage 24LC32AF 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 read currents of only 1 A and 400 A, respectively. It has been developed for advanced, low- power applications such as personal communications Features: or data acquisition. The 24XX32AF also has a page Single Supply with Operation down to 1.7V for write capability for up to 32 bytes of data. Functional 24AA32AF devices, 2.5V for 24LC32AF devices address lines allow up to eight devices on the same bus, for up to 256 Kbits address space. The 24XX32AF Low-Power CMOS Technology: is available in the standard 8-pin PDIP, surface mount - Read current 400 A, max. SOIC, TSSOP, TDFN and MSOP packages. The - Standby current 1 A, max. (I-temp) 24XX32AF is also available in the 5-lead SOT-23 2 2-Wire Serial Interface, I C Compatible package.
