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.
S3C80A5B MICROCONTROLLER
The S3C80A5B single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process and is
based on Samsung's newest CPU architecture.
The S3C80A5B is the microcontroller which has mask-programmable ROM.
Using a proven modular design approach, Samsung engineers developed the S3C80A5B 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 S3C80A5B 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.
