XE8801A – SX8801R Sensing Machine
Data Acquisition with ZoomingADC™
XE8801A – SX8801R
Sensing Machine
Data Acquisition with 16+10 bit ZoomingADC™
General Description
The XE8801A 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 XE8801A includes a high resolution
acquisition path with16+10 bits.
The XE8801A is available with on chip ROM (this
is called the SX8801R) or Multiple-Time-Program-
mable (MTP) program memory.

The counters/timers/PWM can take its clocks from internal or external sources (on Port A) and can generate
interrupts or events. The PWM is output on Port B.
The VLD (voltage level detector) detects the battery end of life with respect to a programmable threshold.
