PRODUCT OVERVIEW
1 PRODUCT OVERVIEW
OVERVIEW
Samsung's S3C8-series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range
of integrated peripherals, and various mask-programmable ROM sizes. Important CPU features include:
— Efficient register-oriented architecture
— Selectable CPU clock sources
— Idle and Stop power-down mode release by interrupt
— Built-in basic timer with watchdog function
A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more
interrupt sources and vectors. Fast interrupt processing (within a minimum six CPU clocks) can be assigned to
specific interrupt levels.
S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 MICROCONTROLLER
The S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 single-chip CMOS microcontroller is fabricated using a
highly advanced CMOS process and is based on Samsung's newest CPU architecture.
The S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 is the microcontroller which has mask-programmable ROM.
The S3P80A4/P80A8/P80A5/P80B4/P80B8/P80B5 is the microcontroller which has one-time-programmable
EPROM.
Using a proven modular design approach, Samsung engineers developed the
S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 by integrating the following peripheral modules with the powerful
SAM87 RC core:
— Three programmable I/O ports, including two 8-bit ports and one 3-bit port, for a total of 19 pins.
— Internal LVD circuit and eight bit-programmable pins for external interrupts.
— One 8-bit basic timer for oscillation stabilization and watchdog functions (system reset).
— One 8-bit timer/counter and one 16-bit timer/counter with selectable operating modes.
— One 8-bit counter with auto-reload function and one-shot or repeat control.
The S3C80A4/C80A8/C80A5/C80B4/C80B8/C80B5 is a versatile general-purpose microcontroller which is
especially suitable for use as remote transmitter controller. It is currently available in a 24-pin SOP and SDIP
package.

Description
Circuit
Type
I/O port with bit-programmable pins.
Configurable to input or push-pull output
mode. Pull-up resistors are assignable by
software. Pins can be assigned individually
as external interrupt inputs with noise filters,
interrupt enable/ disable, and interrupt
pending control. Interrupt with Reset(INTR)
is assigned to Port 0.
1
I/O I/O port with bit-programmable pins.
Configurable to input mode or output mode.
Pin circuits are either push-pull or n-
channel open-drain type. Pull-up resistors
are assignable by software.
2
I/O 3-bit I/O port with bit-programmable pins.
Configurable to input mode, push-pull
output mode, or n-channel open-drain
output mode. Input mode with pull-up
resistors are assignable by software. The
two pins of port 2 have high current drive
capability.
