Overview
The Stamp Pak II 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 II with practically any modern
microprocessor. The Pak II can add, subtract,
multiply, and divide numbers between +/-
6.80564693 x 10³⁸. The smallest number the Pak II
can represent is +/- 1.17549435 x 10^-38. Here are
some of the Pak II'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 16-bits of general-purpose digital I/O
pins
• Fast 20Mhz speed (can be reduced to save
power)
• Easy to use
The Pak II is a standard 28-pin .3” IC. In order to
operate it must have a regulated supply of 5V and
