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.
