The ADUCM360BCPZ128 is a fully integrated, 3.9 kSPS 32-bit Precision Analog Microcontroller incorporates dual high performance, multichannel sigma-delta (Σ-Δ) (Σ-Δ) ADCs, a 32-bit ARM Cortex™-M3 processor and flash/EE memory on a single chip. The ADuCM360 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.
