Microchip | 24LC32AT-I/SN

The 24LC32AT-I/SN is a 32 K serial EEPROM, organized as a single block of 4K x 8-bit memory with a 2-wire serial interface.

The low-voltage design permits operation down to 2.5 V, with standby and active currents of only 1 µA and 1 mA, respectively. It has been developed for advanced, lowpower applications.

Features:

• Single supply with operation:
  • 1.7 V for 24AA32A
  • 2.5 V for 24LC32A
• Low-Power CMOS Technology:
