XE8802 Sensing Machine Data Acquisition MCU
with ZoomingADC™ and LCD driver
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.
