  R104 Impala Microcontroller

Low cost embedded controller with 40 I/O


R104 Impala MicrocontrollerWe are sorry that at this moment we can not guarantee further supply of this R101 controller. The R104 Impala Microcontroller is a compact high performance, low-cost embedded controller built around the Cygnal™ 8051 system-on-chip processor. This C-programmable high-speed microcontroller has digital and analog I/O and serial capability in a small footprint. The R104 Impala's compact design enables ease of use and versatile integration into any in-house or OEM application.

The standard Impala is a low-power device that can be put into sleep mode to conserve power in remote field applications. A serial expansion port is available for additional I/O and communications.
