MDT1010
1. General Description
This ROM-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 1.0 K
bytes of ROM, and 32 bytes of static RAM.
LFXT－Low frequency crystal oscillator
XTAL－Standard crystal oscillator
HFXT－High frequency crystal oscillator
u
4 oscillator start-up time can be
selected by programming option:
150
µs,
