Overview
The ADUC7025BCPZ62 from Analog Devices Inc. is a precision analog microcontroller that integrates high-performance multichannel analog-to-digital converters (ADCs), a powerful 16-bit/32-bit ARM7TDMI microcontroller, and Flash/EE memory on a single chip. This device is part of the ADuC7xxx MicroConverter family, designed for real-time monitoring and analysis of diverse signals with high precision.
The microcontroller features a 12-bit ADC capable of operating at 1 MSPS, with up to 16 ADC input channels, and supports both single-ended and differential input modes. It also includes up to four buffered voltage output digital-to-analog converters (DACs) and various on-chip peripherals such as a temperature sensor, voltage comparator, and a low drift band gap reference.
The device operates from an on-chip oscillator and a phase-lock loop (PLL) generating a high-frequency clock of 41.78 MHz. It has 62 kB of Flash/EE memory and 8 kB of SRAM, and supports in-circuit serial download and JTAG-based debug capabilities.
