• High-speed In-system Programming of all Atmel AT45D Serial DataFLASH memory devices
• Fastest possible programming times due to local data storage of 'Target AT45D Programming Image'
• Support for both 264 / 528 / 1056 byte and also 256 / 512 / 1024 (Power of 2) FLASH Page sizes
• Support for programming the 'Power-of-2' FLASH Page Configuration Fuse
• Supports both fast 'Chip Erase' and also 'Erase page before write' algorithm
• Supports all AT45D silicon revisions from 'A' to 'D' using separately selectable devices
• Supports resetting of target AT45D device to recover from any error state during programming
• Supports programming from a 'Standalone Project' which contains the entire data image of the target AT45DB device.
• Supports programming from a Binary / S-RECORD / Hex file stored on a PC
• Supports programming of unique data such as calibration data, serial numbers etc into specified ranges in the FLASH.
• to minimise the opverall device programming time, it is possible to program non-contiguous blocks / sectors of the FLASH using 'Chained Projects'
• AT45D Serial DataFLASH algorithm available on ISPnano Series 3, ISPnano Series 3 ATE, ISPnano Series 4, ISPnano-MUX 2/4/8 and ISPjuno programmers
• ISPnano-MUX2 programmer is capable of programming a microcontroller and then a AT45DB device sequentially on the same Target Board
• All target I/O lines are fully ESD and over-voltage protected

The programming interface comprises a 3-wire SPI bus (MOSI, MISO, SCK) and an SPI Chip Select signal. This allows multiple SPI devices to use the same SPI bus.

Programmer Signal Name	Signal description	Signal direction (from Programmer)	Target AT45Dxxx Pin name
MOSI	Master OUT, Slave In	Output	SI
MISO	Master IN, Slave OUT	Input	SO
SCK	Serial Clock	Output	SCK
SDF_RESET	SDF - Reset	Output	/RESET
SDF_CS	SDF - Chip Select	Output	/CS
Not connected	SDF – Write Protect	Not connected	/WP
