Flash program memory
4.1
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.
4.2
Main features
●
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
4.3
Programming modes
The ST7 can be programmed in three different ways:
●
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.
4.3.1
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:
1.
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.
2.
Download ICP driver code in RAM from the ICCDATA pin
3.
Execute ICP driver code in RAM to program the Flash memory
