DESCRIPTION
ꢀKey-on wakeup function pins ................................................... 12
ꢀInput/Output port ...................................................................... 14
ꢀA/D converter
The 4508 Group is a 4-bit single-chip microcomputer designed with
CMOS technology. Its CPU is that of the 4500 series using a simple,
high-speed instruction set. The computer is equipped with two 8-bit
timers (each timer has two reload registers), interrupts, 10-bit A/D
converter, Serial interface and oscillation circuit switch function.
10-bit successive comparison method ........................ 4 channel
ꢀSerial intereface ............................................................. 8-bit ꢀ 1
ꢀVoltage drop detection circuit (only for H version)
Reset occurrence .................................... Typ. 2.6 V (Ta = 25 °C)
Reset release .......................................... Typ. 2.7 V (Ta = 25 °C)
ꢀPower-on reset circuit (only for H version)
FEATURES
ꢀMinimum instruction execution time .................................. 0.5 µs
(at 6 MHz oscillation frequency, in through-mode)
ꢀSupply voltage .......................................................... 1.8 V to 5.5 V
(It depends on operation source clock, oscillation frequency and
operating mode.)
ꢀWatchdog timer
ꢀClock generating circuit (on-chip oscillator/ceramic resonator/RC
oscillation)
ꢀLED drive directly enabled (port D)
ꢀTimers
Timer 1................................. 8-bit timer with two reload registers
Timer 2................................. 8-bit timer with two reload registers
ꢀInterrupt ........................................................................ 5 sources
