The MPAA020 is a field programmable analog array based on a general purpose analog cell that may be configured, either alone or in combinations, as any of a wide range of analog functions from simple comparators to complex filters. These cells are arranged in a 4 x 5 array with supporting circuitry to provide input/output signal buffering, programmable reference voltages, cell to cell interconnections, etc. Each cell’s function may be programmed to connect with any of the other cells in the array. Unused cells are powered down individually to minimize power dissipation. Digital interface circuitry is provided to write the analog circuit configuration data to on–chip SRAM in the same manner as Motorola’s digital FPGAs (serial & parallel PROM, and microprocessor mode).

Analog circuit design is simplified with EasyAnalog™ Design Software, which handles bit level circuit configuration details, allowing the user to do analog design using functional macros in an easy to use point–and–click graphical environment.
