Features - - - - - Multi Media Card (MMC) Form Factor Single 2.7V to 3.6V Supply 20 MHz Max Clock Frequency Serial Peripheral Interface (SPI) patible Low Power Dissipation - 4 m A Active Read Current Typical - 2 µA CMOS Standby Current Typical - Industrial Temperature Range - Pb-free/Ro HS-pliant Package 1. Description The AT45DCB008, AT45DCB004 and AT45DCB002 are 2.7-volt only SPI patible serial interface Data Flash® Cards. They are offered in 8-megabyte (64-Mbit), 4-megabyte (32-Mbit) and 2-megabyte (16-Mbit) densities. These 7-pin cards are form factor patible to the Multi Media Card standard leveraging on a wide range of low cost connectors that are mercially available. Additionally, the Data Flash Card is pinout patible to the SPI version of the MMC card. The small form factor and simple interface make the Data Flash Card ideal for a wide variety of data- and program code-storage applications where a removable storage medium is required. Applications range from voice/audio, text or image storage to software applications, system upgrades and software patches.
