Features

  • Small, compact housing
  • Easy to use windows program
  • Serial (in target) programming supported
  • Programming / Verifying / Read back supported
  • OPTION BYTE Programming supported
  • 512 KByte internal Flash memory to store target program
  • High speed programming: app 12 sec for 60 kb in serial mode with 16 MHz target clock for programming and verification
  • Can be used in a production environment
  • PC program allows batch mode processing for usage in automated test systems.
  • Once set up, Flasher can be controlled without the use of PC program

New features

May, the 24th 2005:
ST7Lite3 devices supported by Flasher ST7 software version 1.92d.

May, the 20th 2005:
ST7FMC devices supported by Flasher ST7.
Blank check of ST7 CPUs optimized, runs 10 times faster.
These features are supported by software version 1.92c.

May, the 4th 2005:
Up to 20 COM ports supported by FLASHER PC program.
Additional options and commandline parameter added.
Multiple individual setups can be controlled with command line to support multiple Flasher on one PC.
Readout protection of ST7 devices can now be removed automatically.
Option bytes may be programmed before other FLASH sectors are programmed. This enables fast programming when internal clock of ST7 CPU has to be used.
These features are supported by software version 1.90b.

January 2004:
ASCII command interface implemented to control Flasher from any application without the need of Flasher PC program.
A manual which describes ASCII command interface can be downloaded from our downloadpage.

Supported microcontrollers

The following microcontrollers are supported:

Target system interface

The target system interface from FLASHER ST7 to target system has to be connected to the 10 pin connector, (pin 1 is marked at the connector) as shown in the diagram.

Pin no. Signal Function Specification/remarks
1 GND Common signal ground ---
2 ICCDATA Data signal for ICC protocol communication Open collector output with active pull up
3 GND Common signal ground ---
4 ICCCLK Clock signal for ICC protocol communication Open collector output with active pull up
5 GND Common signal ground ---
6 RESET Target CPU reset FLASHER output (Note 1)
7 VDD Target supply voltage Supplies FLASHERs target interface
8 ICCSEL/VPP Programming voltage for target CPU 12V programming voltage, also used to enter ICC mode
9 OSC_CLK Target CPU clock Supplies system clock to target
10 -- -- Not used for ST7, leave open

Note 1:
If RESET of target system is driven by a reset circuitry with active high driver, RESET output of FLASHER must not be connected directly to CPU reset of target.


Working environment

General
Flasher has been designed for use in a lab or production environment.

Host System
IBM PC/AT or compatible. CPU: 486 (or better) with at least 8Mb of RAM, running Windows 95 / 98 /NT.
It needs to have an RS232 interface available for communication with FLASHER.

Power supply
Flasher ST7 requires 14 - 18V DC, min. 40mA. Please use the power supply which comes with the tool. Flasher is protected against polarity reversion. Please avoid excess volatage.

Installing the FLASHER PC-software

The PC software FLASHER.EXE is distributed on the accommodating 3.5" floppy disk; In order to use the software, install it onto your hard drive and start the executable.

Connecting FLASHER to the PC

PC<-> FLASHER interface cable
A standard serial interface cable (null modem) can be used to connect FLASHER to the PC.
The pin assignment of the 9 pin SUB-D male RS-232 interface connector is as follows:

Pin no. Signal Function Host Signal
2 RxD Serial asynchronous (RS232) data input Serial data output (TxD)
3 TxD Serial asynchronous (RS232) data output Serial data input (RxD)
5 GND Signal ground Signal ground

RS 232 cable

Getting started

   1. Connect FLASHER to a PC running Windows 95/98/2000 or NT using the NULL-modem cable and run the FLASHER software
       FLASHER.EXE
   2. Connect FLASHER to the power supply.
   3. Set up the device via Options menu of PC program
   4. For in-circuit programming: Connect FLASHER to target system via customized interface cable.

Using the FLASHER PC program

General
Flasher comes with an easy to use Windows program. It allows reading of program files in Motorola or Intel hex format. The following is a screen shot of the FLASHER.EXE with loaded target program Flasher.exe main window
