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:
●
●
●
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
Read-out and write protection
Insertion in a programming tool. In this mode, Flash sectors 0 and 1, option byte row
and data EEPROM (if present) can be programmed or erased.
In-circuit programming. In this mode, Flash sectors 0 and 1, option byte row and data
EEPROM (if present) can be programmed or erased without removing the device from
the application board.
In-application programming. In this mode, sector 1 and data EEPROM (if present) can
be programmed or erased without removing the device from the application board and
while the application is running.
