4 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 Program-
ming.
The array matrix organisation allows each sector
to be erased and reprogrammed without affecting
other sectors.

4.3 PROGRAMMING MODES
The ST7 can be programmed in three different
ways:
12/173
1
– Insertion in a programming tool. In this mode,
– In-Circuit Programming. In this mode, FLASH
– In-Application Programming. In this mode,
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
FLASH sectors 0 and 1, option byte row and
data EEPROM (if present) can be pro-
grammed or erased.
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.
sector 1 and data EEPROM (if present) can
be programmed or erased without removing
4.3.1 In-Circuit Programming (ICP)
ICP uses a protocol called ICC (In-Circuit Commu-
nication) which allows an ST7 plugged on a print-
ed circuit board (PCB) to communicate with an ex-
ternal programming device connected via cable.
ICP is performed in three steps:
Switch the ST7 to ICC mode (In-Circuit Communi-
cations). 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 contain-
ing the ICC protocol routine. This routine enables
the ST7 to receive bytes from the ICC interface.
Depending on the ICP Driver code downloaded in
RAM, FLASH memory programming can be fully
customized (number of bytes to program, program
locations, or selection of the serial communication
interface for downloading).
4.3.2 In Application Programming (IAP)
This mode uses an IAP Driver program previously
programmed in Sector 0 by the user (in ICP
mode).
This mode is fully controlled by user software. This
allows it to be adapted to the user application, (us-
er-defined strategy for entering programming
mode, choice of communications protocol used to
fetch the data to be stored etc.)
IAP mode can be used to program any memory ar-
eas except Sector 0, which is write/erase protect-
ed to allow recovery in case errors occur during
the programming operation.
– Download ICP Driver code in RAM from the
– Execute ICP Driver code in RAM to program
the device from the application board and
while the application is running.
