ADUCM361BCPZ128 Description

The ADuCM360 is a fully integrated, 32-bit ARM CortexTM-M3 CPU, dual high performance, multichannel sigma-delta (-) analog-to-digital converters (ADCs), and Flash/EE memory system that supports 24-bit, 3.9 kSPS data capture. Both wired and battery-powered applications can directly interface with external precision sensors using the ADuCM360. All of the functionality of the ADuCM360 are included in the ADuCM361, but there is only one 24-bit -ADC (ADC1) available.

An internal 16 MHz high frequency oscillator and an on-chip 32 kHz oscillator are both present in the ADuCM360/ADuCM361. The operational frequency of the CPU core clock is produced by passing the high frequency oscillator through a configurable clock divider. The maximum core clock speed is 16 MHz; operating voltage or temperature have no bearing on this speed.
