Data Acquisition MCU

with Zooming ADC and DACs

XE8805/05A – SX8805R Sensing

Machine – Data Acquisition with 16+10 bit

ZoomingADC™ and buffered DACs

General Description

The XE8805A is a data acquisition ultra low-

power low-voltage system on a chip (SoC) with a

high efficiency microcontroller unit embedded

(MCU), allowing for 1 MIPS at 300uA and 2.4 V,

and multiplying in one clock cycle.

The XE8805A includes a high resolution

acquisition path with the 16+10 bits ZoomingADC

and two buffered DACs.

The XE8805A is available with on chip ROM (the

SX8805) or Multiple-Time-Programmable (MTP)

program memory.
