MDT1010 Datasheet, PDF (1/20 Pages) Micon Design Technology Corporation – 8-bit micro-controller

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.
2. Features

registers)
u 36 single word instructions
u 14-bit instructions
u 2-level stacks
u Operating voltage : 2.3V ~ 6.3 V
u Operating frequency : 0 ~ 20 MHz
u The most fast execution time is 200 ns
under 20 MHz in all single cycle
instructions except the branch
instruction
u Addressing modes include direct,
indirect and relative addressing modes
u Power-on Reset
u Power edge-detector Reset
u Sleep Mode for power saving
u 8-bit real time clock/counter(RTCC) with
8-bit programmable prescaler
u 4 types of oscillator can be selected by
programming option:
RC Low cost RC oscillator
