µ
PD75036
4 BIT SINGLE-CHIP MICROCOMPUTER
The
µ
PD75036 is a 75X series 4-bit single-chip microcomputer.
The
µ
PD75036 is an expanded version of the
µ
PD75028. It has ROM and RAM with a larger capacity.
The minimum instruction execution time of the
µ
PD75036 is 0.95
µ
s. In addition to this high-speed capability, it
contains an A/D converter and furnishes high-performance functions such as the serial bus interface (SBI) function
that follows the NEC standard format, providing powerful features and high cost performance.
A built-in PROM product,
µ
PD75P036, is also available. The
µ
PD75P036 is suitable for small-scale production
or experimental production in system development.
The following user’s manual describes the details of functions. Be sure to read it before design.
