DESCRIPTION
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.
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.)
● Timers Timer 1 ................................. 8-bit timer with two reload registers Timer 2 ................................. 8-bit timer with two reload registers
● Interrupt ................................................................
