XE88LC01/01A Sensing Machine
Data Acquisition with 16+10 bit ZoomingADC™
General Description
The XE88LC01A is a data acquisition ultra low-
power low-voltage system on a chip (SoC) with a
high efficiency embedded microcontroller unit
(MCU), allowing for 1 MIPS at 300uA and 2.4 V,
and multiplying in one clock cycle.
The XE88LC01A includes a high resolution
acquisition path with16+10 bits.
The XE88LC01A is available with on chip ROM or
Multiple-Time-Programmable (MTP) program
memory.
