The Microchip Technology Inc. 24AA01/24LC01B
(24XX01*) is a 1 Kbit Electrically Erasable PROM. The
device is organized as one block of 128 x 8-bit memory
with a 2-wire serial interface. Low-voltage design
permits operation down to 1.7V with standby and active
Note 1:
100 kHz for V CC <2.5V.
currents of only 1 μ A and 1 mA, respectively. The
24XX01 also has a page write capability for up to 8
Features:
? Single Supply with Operation down to 1.7V for
24AAXX Devices, 2.5V for 24LCXX Devices
? Low-Power CMOS Technology:
