Overview
The Stamp Pak I is a 32-bit floating-point math
coprocessor with a versatile interface that makes it
easy to interface it with a variety of
microcontrollers including the Basic Stamp from
Parallax. However, you can easily interface the
Pak I with practically any modern microprocessor.
The Pak I can add, subtract, multiply, and divide
numbers between +/- 6.80564693 x 10
38. The
smallest number the Pak I can represent is +/-
1.17549435 x 10
-38. Here are some of the Pak I's
major features:
• Robust, speed independent serial interface
• Uses as few as 2 pins to connect to the host
• Can connect multiple devices to the same 2
pins with one additional pin per device
• Can work with IEEE754 floating point
numbers
• Works with Stamp II's ShiftOut and ShiftIn
commands
• Synchronous operation – read results when you
are ready for them
• Adds 8-bits of general-purpose digital I/O pins
• Fast 10Mhz speed (can be reduced to save
power)
• Easy to use
The Pak I 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 I
