Overview
The ADUC7022BCPZ62-RL7 is a precision analog microcontroller from Analog Devices Inc., part of the ADuC7xxx family. This device integrates a high-performance multichannel analog-to-digital converter (ADC), a 16-bit/32-bit ARM7TDMI microcontroller, and nonvolatile Flash/EE memory on a single chip. It is designed for applications requiring precise analog data acquisition and processing. The microcontroller features an ARM7TDMI core, which offers up to 41 MIPS peak performance, and operates from an on-chip oscillator and a phase-locked loop (PLL) generating a 41.78 MHz internal clock. The device is available in a 40-lead LFCSP (Lead Frame Chip Scale Package) with an exposed pad, suitable for surface mount applications.
