8 0 C3 2 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 personal

computer, displays the output data.

The Ma xim 80C32 mic roc ontrolle r (µC) mod ule is

intended for use with this and other Maxim evaluation

kits (EV kits). It contains the 80C32 µC, RS-232 inter-

face, 8kbytes of EPROM, 32kbytes of static RAM, and

address decoding logic. A 40-pin connector mates with

a connector found on Maxim EV kits designed to inter-

face with the 80C32 module.

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 avail-

able 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

me mory c ontrol. The fourth p ort (P1) is a va ila b le

through the data connector.

The 80C32 communicates with the PC over a serial RS-

232 link. A MAX233 acts as a level shifter between the

±15V RS-232 signals and the TTL levels of the 80C32.
