XE8802 Sensing Machine

Data Acquisition SoC with 16+10 bit ZoomingADC™

Embedded RISC controller and LCD driver

General Description

The XE8802 includes a high resolution acquisition

path with the 16+10 bits ZoomingADC™ and an

LCD driver for up to 120 segments. The LCD lines

can be used as additional I/Os.

The embedded core of the XE8802 is an ultra

low-power low-voltage microcontroller unit (MCU)

with a strict 1 instruction per clock processing and

branch speed, allowing for a sustained 4MIPS at

1200µA under 2.4 to 5.5 V.

The XE8802 is available with on chip ROM or

Multiple-Time-Programmable (MTP) program

memory.
