Flash program memory
Introduction
The ST7 single voltage extended Flash (XFlash) is a non-volatile memory that can be
electrically erased and programmed either on a byte-by-byte basis or up to 32 bytes in
parallel.
The XFlash devices can be programmed off-board (plugged in a programming tool) or on-
board using in-circuit programming or in-application programming.
The array matrix organization allows each sector to be erased and reprogrammed without
affecting other sectors.

Programming modes
The ST7 can be programmed in three different ways:
●
●
●
In-circuit programming (ICP)
ICP uses a protocol called I
printed circuit board (PCB) to communicate with an external programming device connected
via cable. ICP is performed in three steps:
●
ICP (in-circuit programming)
IAP (in-application programming)
ICT (in-circuit testing) for downloading and executing user application test patterns in
RAM
Sector 0 size configurable by option byte
Readout and write protection
Insertion in a programming tool
In this mode, FLASH sectors 0 and 1 and option byte row can be programmed or
erased.
In-circuit programming
In this mode, FLASH sectors 0 and 1 and option byte row can be programmed or
erased without removing the device from the application board.
In-application programming
In this mode, sector 1 can be programmed or erased without removing the device from
the application board and while the application is running.
Switch the ST7 to I
ICCCLK/DATA pins while the RESET pin is pulled low. When the ST7 enters I
it fetches a specific RESET vector which points to the ST7 system memory containing
2
C mode. This is done by driving a specific signal sequence on the
2
C (in-circuit communication) which allows an ST7 plugged on a
