DataFlash is a low pin-count serial interface for flash memory. It was developed as an Atmel proprietary interface, compatible with the SPI standard. In October 2012, the AT45 series DataFlash product lines, related intellectual property, and supporting employee teams were purchased by Adesto Technologies. Information is written and read from a DataFlash device using any microcontroller, such as the Atmel AVR, the Microchip PIC or the ARM. The boot ROM of numerous Atmel ARM microcontrollers support downloading code from DataFlash chips after reset. == Examples == The AT45DB161D Integrated circuit (chip) is an example of a 2 MB (16 Mbit) dataflash product. This comes in a 8x5 mm SOIC 8-pin package. This chip is used in a huge number of consumer electronic products. Any microcontroller can use this chip to store data. The AT45DCB008D card is an 8 MB (64 Mbit) flash memory card, which could be mistaken for an MMC or SD card. This DataFlash card packages an AT45DB642D flash chip, which is also available in 8x6 mm CASON 8-pin packages. The AT26 series DataFlash chips are software-incompatible with the original AT45 series chips. They use a simpler command set, supported by other vendors of serial flash but omitting SRAM buffers and other features that make AT45 chips simpler to support. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DataFlash」の詳細全文を読む スポンサード リンク
