The ADUCM361BCPZ128 is a fully integrated, 3.9 kSPS 32-bit Precision Analog Microcontroller incorporates dual high performance, multichannel sigma-delta (Σ-Δ) (Σ-Δ) ADCs, an ARM Cortex-M3 processor and flash/EE memory on a single chip. The ADuCM361 contain an on-chip 32kHz oscillator and an internal 16MHz high frequency oscillator. The high frequency oscillator is routed through a programmable clock divider from which the operating frequency of the processor core clock is generated. The maximum core clock speed is 16MHz, this speed is not limited by operating voltage or temperature. The microcontroller core is a low power ARM Cortex-M3 processor, a 32-bit RISC machine that offers up to 20MIPS peak performance. The Cortex-M3 processor incorporates a flexible, 11-channel DMA controller that supports all wired communication peripherals (SPI, UART and I²C). Also integrated on chip are 128kB of nonvolatile flash/EE memory and 8kB of SRAM.
