Features
Description
• Single Supply with Operation down to 1.7V for
24AA02 and 24FC02 Devices, 2.5V for 24LC02B
Devices
The Microchip Technology Inc. 24XX02(1) is a 2-Kbit
Electrically Erasable PROM. The device is organized
as one block of 256 x 8-bit memory with a 2-wire serial
interface. Its low-voltage design permits operation
down to 1.7V with standby and active currents of only
1 μA and 1 mA, respectively. The 24XX02 also has a
page write capability for up to 8 bytes of data.
• Low-Power CMOS Technology:
- Read current 1 mA, maximum
- Standby current 1 μA, maximum (I-temp.)
• 2-Wire Serial Interface, I2C Compatible
• Schmitt Trigger Inputs for Noise Suppression
• Output Slope Control to Eliminate Ground Bounce
• 100 kHz, 400 kHz and 1 MHz Compatibility
• Page Write Time: 5 ms, Maximum
• Self-Timed Erase/Write Cycle
• 8-Byte Page Write Buffer
