24AA32AFT-I/OT

24AA32AFT-I/OT is a 1.7V, 32-Kbit I²C serial EEPROM with quarter-array write-protect. The device is organized as one block of 4K x 8bit memory with a two-wire serial interface. It also has a page write capability for up to 32 bytes of data. Functional address lines allow up to eight devices on the same bus, for up to 256-Kbit address space.

• Operating current is 400µA max (VCC = 5.5V, SCL = 400KHz, TA = -40°C to +85°C)
• VCC range from 1.7V to 5.5V, clock frequency is 400KHz max (TA = -40°C to +85°C)
• Standby current is 1µA max (SDA = SCL = VCC, A0, A1, A2, WP = VSS, TA = -40°C to +85°C)
• Two-wire serial interface, I²C compatible, packages with 3-addr pins are cascadable up to 8 devices
• Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce
• Write cycle time (byte or page) is 5ms max (TA = -40°C to +85°C, VCC = +1.7V to +5.5V)
• Self-timed erase/write cycle, 32Byte page write buffer, hardware write-protect for 1/4 array
• More than one million erase/write cycles, endurance is 1,000,000cycles max (+25°C, VCC = 5.5V)
• ESD protection <gt/>4,000V
• 5 pin SOT-23 package, industrial operating temperature range from -40 to 85°C
