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 organisation 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 ICC (in-circuit communication) which allows an ST7 plugged on a
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 ICC mode (in-circuit communications). This is done by driving a
specific signal sequence on the ICCCLK/DATA pins while the RESET pin is pulled low.
When the ST7 enters ICC mode, it fetches a specific RESET vector which points to the
ST7 system memory containing the ICC protocol routine. This routine enables the ST7
to receive bytes from the ICC interface.
