1. Description
The AT45DCB008D, AT45DCB004D and AT45DCB002D are 2.7-volt only SPI com-
patible serial interface DataFlash
®
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:
• AT45DCB008D reference AT45DB642D
• AT45DCB004D reference AT45DB321D
• AT45DCB002D reference AT45DB161D

上周五坐在北大英杰交流中心，感受了一场“关乎未来”的辩论风暴。一时间脑洞大开，千万个思绪涌出脑海。假使 AI 全面地取代记者的工作，我应该换个什么职业？是否也会抱怨和怜惜手中被夺走的“鸡”？是否会成为人类迈入人工智能那个被牺牲的一代？嗯，当时的我的确有那么几分担忧。 但此刻坐在电脑前，我一心只求AI附体，助我“四两拨千斤”，快速撸完这一稿。让我把剩下的时间留给星辰大海，留给诗和远方，...[详细]
