The ADUCM350BBCZ is a coin cell powered, high precision, Meter-on-Chip Microcontroller. The ADuCM350 is designed for high precision amperometric, voltametric and impedometric measurement capabilities. The ADuCM350 analog front end (AFE) features a 16-bit, precision, 160kSPS ADC, 0.17% precision voltage reference, 12-bit, no missing codes DAC and a reconfigurable ultralow leakage switch matrix. The ADuCM350 also includes an ARM Cortex-M3-based processor, memory and all I/O connectivity to support portable meters with display, USB communication and active sensors. The ADuCM350 provides a collection of power modes and features, such as dynamic and software controlled clock gating and power gating. The AFE is connected to the ARM Cortex-M3 via an advanced high performance bus slave interface on the advanced microcontroller bus architecture matrix, as well as direct memory access and interrupt connections.
