XE88LC05/05A Sensing Machine
Data Acquisition with 16+10 bit ZoomingADC™
and buffered 16 and 8 bit DACs
General Description
The XE88LC05A 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 XE88LC05A includes a high resolution
acquisition path with the 16+10 bits ZoomingADC
and two buffered DACs.
The XE88LC05A is available with on chip ROM or
Multiple-Time-Programmable (MTP) program
memory.

2.5 Operating speed
2.5.1
Flash version
The speed of the devices is not highly dependent upon the supply voltage. However, by limiting the
temperature range, the speed can be increased. The minimal guaranteed speed as a function of the
supply voltage and maximal temperature operating temperature is given in Figure 2-5.
