PRODUCT OVERVIEW
S3C-SERIES MICROCONTROLLERS
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.
S3C820B MICROCONTROLLER
The S3C820B single-chip CMOS microcontroller is
fabricated using a highly advanced CMOS process
and is based on Samsung’s newest CPU
architecture.
The S3C820B is the microcontroller which has
64K-byte mask-programmable ROM and 192K-byte
mask ROM for font data.
Using a proven modular design approach, Samsung
engineers developed the S3C820B by integrating
the following peripheral modules with the powerful
SAM87 core:
— Four programmable I/O ports, excluding one
BUZ
pin, for a total of 32 pins.
— 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.
— Watch timer for real time.
The S3C820B is a versatile microcontroller for data
bank or dictionary. It is currently available in a 128-
pin QFP package.
