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 • Middle voltage N-ch open drain input/output
approximation): 8 channels

• Capable of operating at low voltage: VDD = 2.7 to • 43 I/O lines can be provided with internal pull-
6.0 V
down resistors
• Reference voltage can be arbitrarily specified • PROM version is available: µPD75P048
between AVREF+ 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
