Embedded Flash

Flash Overview
The Flash of the AT91SAM7XC512 is organized in two banks (dual plane) 0f 1254 pages of
256 bytes. The 524, 288 bytes are organized in 32-bit words.
The Flash of the AT91SAM7XC256 is organized in 1024 pages of 256 bytes (single plane). It
reads as 65,536 32-bit words.
The Flash of the AT91SAM7XC128 is organized in 512 pages of 256 bytes (single plane). It
reads as 32,768 32-bit words.
The Flash contains a 256-byte write buffer, accessible through a 32-bit interface.
The Flash benefits from the integration of a power reset cell and from the brownout detector.
This prevents code corruption during power supply changes, even in the worst conditions.
When Flash is not used (read or write access), it is automatically placed into standby mode.
8.5.2
Embedded Flash Controller
The Embedded Flash Controller (EFC) manages accesses performed by the masters of the sys-
tem. It enables reading the Flash and writing the write buffer. It also contains a User Interface,
mapped within the Memory Controller on the APB. The User Interface allows:
programming of the access parameters of the Flash (number of wait states, timings, etc.)
starting commands such as full erase, page erase, page program, NVM bit set, NVM bit
clear, etc.
getting the end status of the last command
getting error status
programming interrupts on the end of the last commands or on errors
The Embedded Flash Controller also provides a dual 32-bit Prefetch Buffer that optimizes 16-bit
access to the Flash. This is particularly efficient when the processor is running in Thumb mode.
Two EFCs are embedded in the AT91SAM7XC512 to control each bank of 256 KBytes. Dual-
plane organization allows concurrent read and program functionality. Read from one memory
