XE88LC08
12 bit Data Acquisition
Ultra Low-Power Microcontroller
General Description
The XE88LC08 is an ultra low-power microcontroller unit
(MCU) associated with a versatile analog-to-digital con-
verter (ADC).
XE88LC08 is available with on chip Multiple-Time-Pro-
grammable (MTP) Flash program memory and ROM.
Applications

1) Power supply: 2.4 V - 5.5 V, temperature is 27°C.
2) < 10 erase cycles.
3) Output not loaded.
4) Current requirement can be divided by a factor of 2 or 4 by reducing the speed accordingly.
5) More cycles possible during development, with restraint retention
6) Power supply: 3.0V, at 27°C; see chapter Power Consumption on page 23 for variation of
current with voltage and clock speed variation
7) With 2 MHz clock, all instructions are using exactly 1 clock cycle
8) Longer erase time may degrade retention
