4 BIT SINGLE-CHIP MICROCONTROLLER
The
μ
PD750008 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
PD750008 is an advanced model of the
μ
PD75008. It features an enhanced CPU function and enables high-
speed operation at a low voltage of 2.2 V. It can be substituted for the
μ
PD75008. In addition, it is best suited to
applications using batteries. The
μ
PD750008(A) has a higher reliability than the
μ
PD750008.
A built-in one-time PROM product,
μ
PD75P0016, 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
PD750008. Be sure to read it
before designing application systems.

PD750004,
μ
PD750006, and
μ
PD750008
Cordless telephones, radio devices, audio products, and home electric appliances
μ
PD750004(A),
μ
PD750006(A), and
μ
PD750008(A)
Electrical equipment for automobiles
The
μ
PD750004,
μ
PD750006,
μ
PD750008,
μ
PD750004(A),
μ
PD750006(A), and
μ
PD750008(A) differ only in
quality grade. In this manual, the
μ
PD750008 is described unless otherwise specified. Users of other than the
μ
PD750008 should read
μ
PD750008 as referring to the pertinent product.
When the description differs among
μ
PD750004,
μ
PD750006, and
μ
PD750008, they also refer to the pertinent
(A) products.
