1.2 Step 1: Installing the Programmer Board
The programmer board (shown in figure 1-1) is designed to accept five types
of integrated circuits (ICs):
- 40-pin dual inline packages (DIPs)
- 28-pin DIPs
- 28-pin plastic leaded chip carriers (PLCCs)
- 68-pin PLCCs
- 44-pin PLCCs
These types of ICs fit the following ’370 devices:
TMS370C702 TMS370C712 TMS370C722 TMS370C732
TMS370C742 TMS370C250 TMS370C256 TMS370C756
TMS370C758 TMS370C768 TMS370C777
TheprogrammerboardalsoprogramstheEEPROMfortheROMdevicesthat
the one-time programmable (OTP) devices above support. Prototyping de-
vices (devices with SE prefixes) are also supported.
The locations of the different ICs in the programmer board are represented in
Figure 1–1 as IC1 to IC5.
A slide switch (S1) applies power to the IC to be programmed.

Step 1: Installing the Programmer Board
1-5 Installing the Programming Tool With Windows
Improper connection of the programmer board can damage your
programmer and/or your PC.
Do not attempt to plug in multiple devices. Plugging in multiple
devices can damage your PC and/or programmer.
To install the programmer board, follow these steps:
1) Turn the powerswitch(S1) ontheprogrammerboard totheOFF position.
2) Connect the programmer to the PC. In order to use the ’370 programmer
board, you must use a “straight-through” RS-232 cable with the connec-
tions between the programmer board and a full-duplex communications
(serial) port on your PC, as shown in Table 1–1.
Table 1–1. Host Cable Pin and Signal Assignments

reljack (P1). Alternatively,you canconnect thepowersupply to thescrew
power socket (P2). The + and – input lines are labeled on the printed
board. Be sure that the power to the programmer board is off.
Inserting or removing ICs while power is applied to the socket can
damage your ICs.
5) Insert the integrated circuit (IC).
6) Turn on the programmer by sliding switch S1 to the POWER position. If
necessary, youcanreset the programmerboard via thereset push button
(R1).
