ADuCM362/ADuCM363, 32-Bit ARM® Cortex®-M3 Microcontrollers (MCUs)

Analog Devices offers its low power, precision MCUs with sigma-delta (Σ-Δ) analog-to-digital converters (ADCs)

Image of Analog Devices' ADuCM362/ADuCM363, 32-Bit ARM® Cortex™-M3 Microcontrollers (MCU)ADI’s ADuCM362/ADuCM363 are fully integrated, 3.9 kSPS, 24-bit data acquisition systems that incorporate dual, high performance, multichannel Σ-Δ ADCs, 32-bit ARM Cortex-M3 processors, and Flash/EE memory on a single chip. These devices are designed for direct interfacing to external precision sensors in both wired and battery-powered applications. ADuCM362/ADuCM363 sharel the same features, except the AduCM362 has dual 24-bit Σ-Δ ADCs whereas the AduCM363 has only one.

These devices contain an on-chip 32 kHz oscillator and an internal 16 MHz 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 16 MHz; this speed is not limited by operating voltage or temperature.

On-chip factory firmware supports in-circuit serial download via a serial wire interface (2-pin JTAG system) and UART; non-intrusive emulation is also supported via the serial wire interface. These features are incorporated into a low cost QuickStart™ development system that supports this precision analog micro-controller family. The ADuCM362/ADuCM363 operate from an external 1.8 V to 3.6 V voltage supply and are specified over an industrial temperature range of -40°C to 125°C and come in a 48-LFCSP package.
