Overview
The Stamp PAK VI allows you to use an ordinary
PS/2 or AT-style keyboard with any computing
device capable of handling RS232
communications. The PAK VI is the perfect
solution for microcontrollers that need real input.
It provides a raw mode for ultimate control or a
cooked mode that makes interfacing with the
keyboard simple.
Here are some of the PAK V's major features:
Serial interface uses TTL level RS232 at 9600
Uses as few as 1 pin to connect to the host
Buffers up to 16 keystrokes or scan codes
Easy to use
The PAK VI is a standard 18-pin IC. In order to
operate it must have a regulated supply of 5V and
connection to a clock element. The Stamp PAK VI
includes a 50MHz ceramic resonator that you can
use to clock the chip.
Other than the power and clock connections, the
Pak VI requires at least one wire to connect
between your microcontroller (the host) and itself.
Depending on the host's capabilities and your
application, you may want to use a few additional
pins to control the PAK

Registering Your PAK-VI
Please take a moment to register your e-mail
address with AWC. Simply send an e-mail
message to pakreg@al-williams.com. AWC will
not make your address available to other
companies, but we may periodically send you
updated technical notes. You'll also receive
information about new microcontroller products
and specials.
WARNING: The PAK VI is a static-sensitive,
CMOS device. Observe static precautions
when handling. Operating the device without
both Vss pins grounded or with RES1 or RES2
disconnected may damage the chip.
