Keywords:cml microcircuits? cmx850? communications controller ic?
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. |
