µPD75048

4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The µPD75408 is a 4-bit single-chip microcomputer whose data processing capability is comparative to that

of an 8-bit microcomputer.

The µPD75048 employs a CPU whose minimum instruction execution time is 0.95 µs, and contains the

EEPROM, A/D converter, multi-function timer, and high performance hardware to provide high cost to

performance ratio.

Detailed functions are described in the following user's manual. Read this manual when designing your

system.

µPD75048 User's Manual: IEU-704

FEATURES

• Built-in EEPROM: 1024 x 4 bits (data memory area) • I/O ports: 48 pins

• Built-in 8-bit resolution A/D converter (successive

approximation): 8 channels

• Middle voltage N-ch open drain input/output

ports: 12 pins

• Capable of operating at low voltage: V^DD= 2.7 to

6.0 V

• 43 I/O lines can be provided with internal pull-

down resistors

• Reference voltage can be arbitrarily specified • PROM version is available:µPD75P048

between AV^REF+and AVREF- (One-time PROM)

• Built-in multi-function timer which can provide the

following functions:

• 8-bit timer

• PWM output

• 16-bit free running timer

• 16-bit integration type A/D converter counter

APPLICATIONS

• Consumerelectronicsproducts,telephones,cameras,automobileaudioequipment,electronicsmeasurement

equipment, etc.
