MDT2005(JG)
1. General Description
This EPROM-Based 8-bit micro-controller
uses a fully static CMOS design
technology combines higher speeds and
smaller size with the low power and high
noise immunity of CMOS.
On chip memory system includes 0.5 K(for
MDT2005) bytes of ROM, and 32 bytes of
static RAM.
Power-on Reset (POR), only available
while PED is Disable
Power edge-detector Reset (PED)
Sleep Mode for power saving
8-bit real time clock/counter(RTCC)
with 8-bit programmable prescaler
4 types of oscillator can be selected
by programming option:
RC－Low cost RC oscillator
LFXT－Low frequency crystal
oscillator
XTAL－Standard crystal oscillator
HFXT－High frequency crystal
oscillator
4 oscillator start-up time can be
selected by programming option:
150
µs,
20 ms, 40 ms, 80 ms
On-chip RC oscillator based
Watchdog Timer(WDT) can be operated
freely
12 I/O pins with their own independent
direction control
