Analog MCU with on-chip data conversion simplify optical module design

Analog Devices Inc.’s ADuC7023 and ADuC7122 precision analog microcontrollers (MCUs) use an ARM7 processor with up to 126kB of flash memory to ensure the accurate control of optical drivers and diagnostics.

The MCUs feature on-chip 12-bit ADCs and DACs, which reduce the size of the overall solution by up to 75 percent compared to competing discrete solutions. The devices support interrupt nesting and up to 16 levels of interrupt priority, and retain DAC and GPIO outputs during a software or watchdog reset. The devices come in a 7x7mm 108-ball BGA package.
