CML Microcircuits Ltd has announced the enhancement of its facilities for it CMX850 low-power, single-chip communications controller IC line. The company claims that the communications processor is the first embedded microcontroller of its kind with an integrated V.22bis modem and comprehensive wireline signaling facilities.

For use in embedded systems, the CMX850 is an 80C51 microcontroller with 8K of on-chip RAM, an integral modem capable of working to V22bis, V.22, V.23, V.21, and up to 35 General Purpose I/O pins. It is capable of directly accessing up to 4MB of external memory through 'page-mode' addressing.

Other main features include a 16x8 keyboard encoder, an interface for an external LCD controller, CAS Tone detection and generation, and advanced power management. A dual clock operation, watch dog timer, real-time clock, two-input ADC, and two low-power PWM outputs are also included.

Fully functional in the range of 3V to 3.6V, the product requires 6.5mA at full operation, and is available in a 100-lead low-profile plastic quad-flat package.
