Radio communication evaluation / development kit CML Microcircuits

The CMX850 combines a dual-port V.22bis modem with an 8051 microcontroller including 8k of RAM to form a powerful communications processor. Extended addressing offers page-mode access to 4Mbytes of external FLASH memory. The 8051 runs from the ~12MHz oscillator with a choice of sub-multiple frequencies down to ~12kHz giving a range of low power operating modes.
