4 BIT SINGLE-CHIP MICROCONTROLLER

The µPD750108 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 µPD750108 is produced by replacing the main system clock oscillator of the µPD750008 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 µPD750108(A) has a higher reliability than the µPD750108.

A built-in one-time PROM product, µPD75P0116, 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 µPD750108. Be sure to read it

before designing application systems.

µPD750108 User’s Manual: U11330E

FEATURES

• Built-in RC oscillator

• Enables the immediate start of processing after the

release of standby mode

• Capable of low-voltage operation: VDD = 1.8 to 5.5 V

• Internal memory

Program memory (ROM)

: 4,096 × 8 bits (µPD750104 and µPD750104(A))

: 6,144 × 8 bits (µPD750106 and µPD750106(A))

: 8,192 × 8 bits (µPD750108 and µPD750108(A))

Data memory (RAM)

: 512 × 4 bits

• Function for specifying the instruction execution time

(useful for saving power)

4 µs, 8 µs, 16 µs, 64 µs (when operating at 1.0 MHz)

2 µs, 4 µs, 8 µs, 32 µs (when operating at 2.0 MHz)

122 µs (when operating at 32.768 kHz)

• Enhanced timer function (4 channels)

• Can be easily substituted for the µPD750008 because

this product succeeds to the functions and instructions

of the µPD750008.

APPLICATIONS

• µPD750104, µPD750106, and µPD750108

Cameras, meters, and pagers

• µPD750104(A), µPD750106(A), and µPD750108(A)

Electrical equipment for automobiles

The µPD750104, µPD750106, µPD750108, µPD750104(A), µPD750106(A), and µPD750108(A) differ only in

quality grade. In this manual, the µPD750108 is described unless otherwise specified. Users of other than the

µPD750108 should read µPD750108 as referring to the pertinent product.

When the description differs among µPD750104, µPD750106, and µPD750108, they also refer to the pertinent

(A) products.
