1 PRODUCT OVERVIEW

S3C8-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. Among the major CPU features are:

—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 of four CPU clocks) can be assigned to specific interrupt levels.

S3C8248/C8245/P8245/C8247/C8249/P8249 MICROCONTROLLER

The S3C8248/C8245/P8245/C8247/C8249/P8249 single-chip CMOS microcontroller are fabricated using the highly advanced CMOS process, based on Samsung’s newest CPU architecture.

The S3C8248, S3C8245, S3C8247, S3C8249 are a microcontroller with a 8K-byte, 16K-byte, 24K-byte. 32K-byte mask-programmable ROM embedded respectively.

The S3P8245 is a microcontroller with a 16K-byte one-time-programmable ROM embedded.

The S3P8249 is a microcontroller with a 32K-byte one-time-programmable ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C8248/C8245/P8245/C8247/C8249/P8249 by integrating the following peripheral modules with the powerful SAM8 core:

—Six programmable I/O ports, including five 8-bit ports and one 5-bit port, for a total of 45 pins.

—Eight bit-programmable pins for external interrupts.

—One 8-bit basic timer for oscillation stabilization and watchdog functions (system reset).

—Two 8-bit timer/counter and two 16-bit timer/counter with selectable operating modes.

—Watch timer for real time.

—8-input A/D converter

—Serial I/O interface

The S3C8248/C8245/P8245/C8247/C8249/P8249 is versatile microcontroller for camera, LCD and ADC application, etc. They are currently available in 80-pin TQFP and 80-pin QFP package

OTP

The S3P8245/P8249 are OTP (One Time Programmable) version of the S3C8245/C8249 microcontroller. The S3P8245 microcontroller has an on-chip 16K-byte one-time-programmable EPROM instead of a masked ROM. The S3P8249 microcontroller has an on-chip 32K-byte one-time-programmable EPROM instead of a masked ROM. The S3P8245 is comparable to the S3P8245, both in function and in pin configuration.

The S3P8249 is comparable to the S3P8249, both in function and in pin configuration.
