1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The S3C72H8 single-chip CMOS microcontroller has been designed for very high performance using Samsung's
state-of-the-art 4-bit product development approach, SAM47 (Samsung Arrangeable Microcontrollers). Its main
features are an up-to-13-digit LCD direct drive capability, 2-channel comparator inputs and outputs, and versatile
8-counter/ timers and 16-bit frequency counter. The S3C72H8 gives you an excellent design solution for a variety
of LCD-related applications, specially thermostat control application.
Up to 21 pins of the available 64-pin QFP packages can be dedicated to I/O. And six vectored interrupts provide
fast response to internal and external events.
In addition, the S3C72H8's advanced CMOS technology provides for low power consumption and a wide oper-
ating voltage range.

Description
3-bit I/O port.
1-bit and 4-bit read/write and test is possible.
Port 0 is software configurable as input or output. 3-bit
pull-up resistors are software assignable.
4-bit I/O port.
1-bit and 4-bit read/write and test is possible.
Individual pins are software configurable as input or
output. 4-bit pull-up resistors are software assignable.
Same as port 2.
Ports 2 and 3 can be addressed by 1, 4, and 8-bit
read/write and test instruction.
4/2-bit I/O ports. N-channel open-drain or push-pull
output. 1, 4, and 8-bit read/write and test is possible.
Ports 4 and 5 can be paired to support 8-bit data
transfer. Pull-up resistors are assignable to port unit by
software control.

I/O 4-bit I/O ports. Port 6 pins are individually software
configurable as input or output. 1-bit and 4-bit read/write
and test is possible. 4-bit pull-up resistors are software
assignable.
BTCO
I/O Basic timer clock output
CLO
I/O CPU clock output
BUZ
I/O 2, 4, 8 or 16 kHz frequency output for buzzer sound with
4.19MHz main-system clock or 32.768 kHz sub-system
clock.
XOUT, XIN
– Crystal, ceramic, or RC oscillator signal for main-
system clock. (For external clock input, use XIN and
input XIN’s reverse phase to XOUT)
XTOUT,
XTIN
– Crystal oscillator signal for sub-system clock.
(For external clock input, use XTIN and input XTIN’s
reverse phase to XTOUT)
INT0, INT1 I/O External interrupts. The triggering edge for INT0 and
Int1 is selectable. Only INT0 is synchronized with the
system clock.
