GENERAL DESCRIPTION

The ADuCM350 is a complete, coin cell powered, high

precision, meter-on-chip for portable device applications for

applications such as point-of-care diagnostics and body-worn

devices for monitoring vital signs. The ADuCM350 is designed

for high precision amperometric, voltametric, and impedometric

measurement capabilities.

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. 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 (AHB) slave interface on the advanced

microcontroller bus architecture (AMBA) matrix, as well as

direct memory access (DMA) and interrupt connections.
