The XE88LC05 includes usual microcontroller peripherals and some other blocks more spe-
cific to low-voltage or mixed-signal operation. There are 3 parallel ports, one input port (A), one
IO and analog port (B) with analog switching capabilities and one general purpose IO port (C).
A watchdog is available, connected to a prescaler. Four 8-bit counters, with capture, PWM and
chaining capabilities are available. The UART can handle transmission speeds as high as
115kbaud.
Low-power low-voltage blocks include a voltage level detector, two oscillators (one internal
0.1-2 MHz RC oscillator and a 32 kHz crystal oscillator) and a specific regulation scheme that
largely uncouples current requirement from external power supply (usual CMOS ASICs re-
quire much more current at 5.5 V than they need at 2.4 V. This is not the case for the
XE88LC05).
Analog blocks (ZoomingADC (acquisition path), bias DAC and signal DAC) are defined below.
All these blocks operate on 2.4 - 5.5 V power supply range.
