DESCRIPTION
address decoding logic. A 40-pin connector mates
with a connector found on Maxim EV kits designed to
interface with the 80C32 module.
The module is connected to an IBM-compatible per-
sonal computer over a serial communications port.
Software provided with each EV kit runs on the comput-
er and controls the unit consisting of the 80C32 module
and EV kit. The program uses a routine stored in the
27C64 EPROM to download special 80C32 code for
each kit. The downloaded code controls the EV kit
and, together with the program running on the person-
al computer, displays the output data.
The board operates from a single 8V to 22V supply.
Both the pre-regulated and regulated +5V levels are
available to the EV kit through the 40-pin connector.
The Maxim 80C32 module requires an input of 8V to 22V
for normal operation. An on-board 78M05 power regula-
tor supplies the 5V required for the logic on the module,
and any 5V requirements for the EV kit attached to the
40-pin connector. The pre-regulated voltage is also
available on the data connector. The source must be
capable of supplying 100mA for the module and meeting
the load requirements of the EV kit.
A MAX707 on the module monitors the 5V logic supply,
generates the power-on reset, and produces a reset
pulse whenever the reset button is pressed. A watch-
dog function was not included because they frequently
interfere while debugging programs, and debugging is
a prime function of this board.
The 80C32 is a member of the popular Intel 8051 family
of µCs. It is a low-power CMOS version that requires
external ROM for program storage, 256 bytes of inter-
nal RAM, and four 8-bit I/O ports. Three of the ports
are required by the system for serial communications
and memory control. The fourth port (P1) is available
through the data connector.
