The Microchip Technology Inc. 24AA512/24LC512/ Number Range Frequency Ranges 24FC512 (24XX512*) is a 64K x 8 (512 Kbit) Serial (1) Electrically Erasable PROM, capable of operation 24AA512 1.7-5.5V 400 kHz I across a broad voltage range (1.7V to 5.5V). It has 24LC512 2.5-5.5V 400 kHz I, E been developed for advanced, low-power applications (2) 24FC512 1.7-5.5V 1 MHz I such as personal communications and data acquisi- tion. This device also has a page write capability of up Note 1: 100 kHz for VCC < 2.5V to 128 bytes of data. This device is capable of both 2: 400 kHz for VCC < 2.5V random and sequential reads up to the 512K boundary. Functional address lines allow up to eight devices on Features: the same bus, for up to 4 Mbit address space. This device is available in the standard 8-pin plastic DIP, Single Supply with Operation down to 1.7V for SOIJ, SOIC, TSSOP, DFN, and 14-lead TSSOP 24AA512 and 24FC512 Devices, 2.5V for packages. The 24AA512 is also available in the 8-lead 24LC512 Devices Chip Scale package.
