ADUCM350BBCZ-RL
ARM Cortex-M3 16MHz 闪存：384K@x8bit
Product Details
The ADuCM350 is a configurable Impedance Converter and Potentiostat with current and voltage measurement capability for both Electrochemical sensors and Biosensors. It is a complete, coin cell powered, high precision, MCU integrated solution for portable device applications such as point-of-care diagnostics and body-worn devices for monitoring vital signs.
The ADuCM350 analog front end AFE features a 16-bit, precision, 160 kSPS analog-to-digital converter ADC; 0.17% precision voltage reference; 12-bit, no missing codes digital-to-analog converter DAC; and a reconfigurable ultralow leakage switch matrix. It has 4 voltage measurement channels, up to 8 current measurement channels and an impedance measurement DFT engine. 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 is available in a 120-lead, 8 mm × 8 mm CSP_BGA and operates from −40°C to +85°C.
To support extremely low dynamic and hibernate power management, 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 AHPB slave interface on the advanced microcontroller bus architecture AMBA matrix, as well as direct memory access DMA and interrupt connections.
