Description

The Microchip Technology Inc. 24AA01/24LC01B (24XX01*) is a 1 Kbit Electrically Erasable PROM. The device 24AA01 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 currents of only 1 A and 1 mA, respectively. The 24XX01 also has a page write capability for up to 8 bytes of data. The 24XX01 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 DFN and MSOP packages, and is also available in the 5-lead SOT-23 package.

The Microchip Technology Inc. 24AA01 and 24AA02 are 1K bit and 2K bit Electrically Erasable PROMs. The devices are organized as a single block of 128 x 8-bit or 256 x 8-bit memory with a two wire serial interface.Low-voltage design permits operation down to 1.8 volts with standby and active currents of only 3mA and 1 mA,respectively. The 24AA01 and 24AA02 also have pagewrite capability for up to 8 bytes of data. The 24AA01 and 24AA02 are available in the standard 8-pin DIP and 8-pin surface mount SOIC packages.
