MDT10P157
1. General Description
This EPROM-Based 8-bit micro-controller
uses a fully static CMOS design
technology combines higher speed and
smaller size with the low power and high
noise immunity of CMOS.
On chip memory system includes 2.0 K
words of ROM, and 80 bytes of static
RAM.
4 types of power edge-detector reset:
1.8v , 2.1v , always enable 1.8v and
Disable
Sleep mode for power saving
2 oscillator start-up time can be
selected by programming option：
150
μ
s,20ms
