The ADuCM361 is a fully integrated, 4 kSPS, 24-bit data acquisition system incorporating high performance multi-channel sigma-delta (Σ-Δ) analog-to-digital converter (ADC), 32-bit ARM Cortex M3? MCU, and Flash/EE memory on a single chip allowing direct interfacing to external precision sensors in both wired and battery powered applications.
The ADuCM361 contains all the features of the ADuCM360 except that one of the AFE’s is removed.
The device contains an on-chip 32 KHz oscillator and an internal 16MHz high-frequency oscillator. This clock is routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The maximum core clock speed is 16MHz, not limited by operating voltage or temperature.
The microcontroller core is a low power ARM Cortex-M3, 32-bit RISC machine, offering up to 20 MIPS peak performance, incorporating a flexible 11-channel DMA controller supporting SPI, UART, I2C communication peripherals. 128k Bytes Flash/EE and 8k Bytes SRAM are integrated on-chip.
