4 BIT SINGLE-CHIP MICROCONTROLLER
The
μ
PD750108 is one of the 75XL series 4-bit single-chip microcontrollers, which provide data processing
capability equal to that of an 8-bit microcontroller.
The
μ
PD750108 is produced by replacing the main system clock oscillator of the
μ
PD750008 with an RC oscillator,
enabling operation at a relatively low voltage of 1.8 V. In addition, it is best suited to applications using batteries.
The
μ
PD750108(A) has a higher reliability than the
μ
PD750108.
A built-in one-time PROM product,
μ
PD75P0116, is also available. It is suitable for small-scale production and
evaluation of application systems.
The following user’s manual describes the details of the functions of the
μ
PD750108. Be sure to read it
before designing application systems.

Electrical equipment for automobiles
The
μ
PD750104,
μ
PD750106,
μ
PD750108,
μ
PD750104(A),
μ
PD750106(A), and
μ
PD750108(A) differ only in
quality grade. In this manual, the
μ
PD750108 is described unless otherwise specified. Users of other than the
μ
PD750108 should read
μ
PD750108 as referring to the pertinent product.
When the description differs among
μ
PD750104,
μ
PD750106, and
μ
PD750108, they also refer to the pertinent
(A) products.
