| Features * * * * * MultiMediaCard (MMC) Form Factor Single 2.7V to 3.6V Supply 20 MHz Max Clock Frequency Serial Peripheral Interface (SPI) Compatible Low Power Dissipation - 4 mA Active Read Current Typical - 2 A CMOS Standby Current Typical * Industrial Temperature Range Description The AT45DCB008, AT45DCB004 and AT45DCB002 are 2.7-volt only SPI compatible serial interface DataFlash(R) 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 compatible to the MultiMediaCard standard leveraging on a wide range of low cost connectors that are commercially available. Additionally, the DataFlash Card is pinout compatible to the SPI version of the MMC card. The small form factor and simple interface make the DataFlash 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. For detailed device specifications, please refer to the corresponding DataFlash datasheets: * * * AT45DCB008 reference AT45DB642 AT45DCB004 reference AT45DB321B AT45DCB002 reference AT45DB161B 8-megabyte, 4-megabyte, and 2-megabyte 2.7-volt Only DataFlash(R) Cards AT45DCB008 AT45DCB004 AT45DCB002 Pin Configuration Pin # 1 2 3 4 5 6 7 Pin Name CS SI GND VCC SCK NC SO Function Chip Select Serial Input 7654321 DataFlash Card Top View Ground Supply Serial Clock No Connect Serial Output Rev. 3257A-11/01 1 Ordering Information fSCK (MHz) 20 ICC (mA) Active 10 Standby 0.01 Ordering Code AT45DCB008 AT45DCB004 AT45DCB002 Package 7DF1 Operation Range Industrial (-40C to 85C) Package Type 7DF1 7-lead, 2.5 mm Pitch 24 x 32 x 1.4 mm Body DataFlash Card 2 AT45DCB002/B004/B008 3257A-11/01 AT45DCB002/B004/B008 Packaging Information 7DF1 - DataFlash Card E2 LABEL AREA A D D1 3XR1.0 E1 SIDE VIEW R0.25 ALL AROUND E TOP VIEW E3 e B G 1234567 SYMBOL A B C D D1 E COMMON DIMENSIONS (Unit of Measure = mm) MIN 1.30 NOM 1.40 2.40 TYP 4.00 TYP 31.90 32.00 28.00 REF 23.90 24.00 22.00 REF 20.00 REF 15.00 TYP 20.00 REF 15.00 TYP 2.50 TYP 24.10 32.10 MAX 1.50 NOTE C F E1 E2 BOTTOM VIEW E3 F G e 10/09/01 2325 Orchard Parkway San Jose, CA 95131 TITLE 7DF1, 7-pad, 2.5 mm Pitch 24 x 32 x 1.4 mm Body DataFlash Card DRAWING NO. 7DF1 REV.
