DESCRIPTION
The 4552 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 one or two reload registers), a 16-
bit timer for clock count, interrupts, and oscillation circuit switch
function.
The various microcomputers in the 4552 Group include variations
of the built-in memory size as shown in the table below.
FEATURES
qMinimum instruction execution time
Mask ROM version .............................................................. 0.5 µs
(at 6 MHz oscillation frequency, in high-speed through-mode)
One Time PROM version ................................................... 0.68 µs

qSupply voltage
Mask ROM version ...................................................... 1.8 to 5.5 V
One Time PROM version ............................................. 1.8 to 3.6 V
(It depends on operation source clock, oscillation frequency and op-
eration mode)
