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 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:
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.

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, 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.
