Programming the Atmel
AT91SAM7 Families
The 16/32-bit Atmel AT91SAM7 family is based on the ARM7TDMI processor. It provides the optimal combination of processor power, on-chip peripherals and memory blocks for demanding real-time applications that require high performance on a tight power budget and is an ideal design solution for
8-bit microcontrollers get a quantum jump over real time performance. With a rich set of peripherals and
a complete set of system functions, these controllers are designed for using in a range of applications
including industrial control, automotive, medical, connectivity and any
other general purpose embedded application requiring high performance and
low power consumption in a cost-effective package.

AT91SAM families include AT91SAM7AX series and AT91SAM7SXX series, so far have totally 7 microcontroller members. Most of these microcontrollers have
on-chip flash. Some of these microcontrollers can not add external flash
chip. We summarize it here:
With on-chip flash: AT91SAM7S32/64/128/256, AT91SAM7A3.
Capable of adding external flash chip: AT91SAM7A1/A2.
Embest Flash Programmer supports programming these on-chip flashs and
external flash chips of the AT91SAM7 families via jtag interface. This is very useful for customers. Embest Flash Programmer can be released as a powerful tool for Embest IDE for ARM package, it also can be released as an individual tool for customers used for programming flash chip.This software must be applied together with ARM emulator made by Embest or a JTAG cable made by yourself which we describe in our document. When purchase this tool individually, you should make a JTAG cable by yourself or buy an Embest Jtag emulator(PowerICE or Emulator or UNetICE). We have offered detail document about how to make a JTAG cable by yourself.
The software interface of Embest Flash Programmer is showed below:
