 Only 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.
