The ADuCM362/ADuCM363 of Analog Devices is a fully integrated, 3.9 kSPS, 24 bit data acquisition system, including dual, high-performance, multi-channel Sigma Delta adc, 32-bit ARM Cortex-M3 processor, and Flash/EE memory on a single chip. These devices are designed for direct connection to external precision sensors, whether wired or battery powered. The ADuCM362/ADuCM363 has the same characteristics, except that the ADuCM362 has a double 24 bit sigma delta adc, while the ADuCM363 has only one 24 bit sigma delta adc.
These devices include 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, which generates the operating frequency of the processor core clock. The maximum core clock speed is 16 MHz; This speed is not limited by operating voltage or temperature.
Factory on chip firmware supports online serial download through serial line interface (2-pin JTAG system) and UART; Non intrusive simulation is also supported through the serial line interface. These functions were combined into a low-cost rapid start development system to support this family of precision analog microcontrollers. The ADuCM362/ADuCM363 operates from an external 1.8 V to 3.6 V voltage supply, specified within the industrial temperature range of - 40 ° C to 125 ° C, and is packaged with 48 lfcsp.
