APPLICATION NOTE
ST7 SERIAL TEST CONTROLLER PROGRAMMING
by Microcontroller Division Applications
INTRODUCTION
This application note describes:
– The advantages of Serial Test Controller Programming (STCP) vs. programming using an
EPROM programming board (EPB) (see Section 2.1).
– How to implement Serial Test Controller Programming targeting most of the ST7 general pur-
pose microcontrollers (see Section 2.2). These devices include all parts supported by the
ST7 starter kits and ST7 EPBs in the MDT1, MDT2 and MDT4 tool families (see the support-
ed device list in APPENDIX 1).
Note: In this application note, the term “programming tool” refers to either the EPBs or the
starter kits.
1 PROGRAMMING TECHNIQUES
There are two possible ways of programming an ST7 device:
s Using a programming tool. In this case, the device is first plugged on the programming board
and then programmed. Then, the part is soldered or plugged into a socket on the user board.
This can be done using any of the following ST7 programming tools:
– ST7 Starter Kit
– ST7 EPB (EPROM Programming Board)
– ST7 Gang Programmer
For further details about the above tools, please refer to the user manual supplied with these
devices.
s Using a Serial Test Controller Programming (STCP) tool. This technique allows a device to
be directly programmed on the user board. This is a two-step procedure where first the
board is first manufactured with a blank ST7, and afterwards the chip is programmed using
a programming tool (Starter Kit or EPB).
This application note describes the STCP method only.
