Low cost embedded controller 16 Inputs + 14 Outputs + Analog I/O


R103 Gazelle CPOnly limited stock of this R103 is still available. We are sorry that at this moment we can not guarantee further supply of this R103 controller.  The R103 Gazelle-CP Microcontroller is a compact, high performance, low-cost operator interface built around the new Cygnal™ 8051 system-on-chip processor. This C-programmable high-speed controller has digital, analog, and serial capabilities. The R103 Gazelle-CP's compact design enables ease of use and versatile integration into any in-house or OEM application.

Available interfaces include, digital inputs, analog inputs/outputs, serial communications and high-current drivers. The standard Gazelle-CP is packaged in a metal enclosure with a Nema 4 bezel for the 4x20 LCD and 3x4 tactile keypad. The Gazelle-CP also has a serial expansion port for additional I/O and communications.

Sample programs with the Keil C compiler are supplied.
