| S3C8248/C8245/P8245/C8247/C8249/P8249 PRODUCT OVERVIEW 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. 1-1 PRODUCT OVERVIEW S3C8248/C8245/P8245/C8247/C8249/P8249 FEATURES Memory * * * * * * * * * * * * * * ROM: 32K-byte (S3C8249/P8249) ROM: 16K-byte (S3C8245/P8245) RAM: 1056-Byte (S3C8249/P8249, S3C8247) RAM: 544-Byte (S3C8245/P8245, S3C8248) Data memory mapped I/O Crystal, ceramic, RC (main) Crystal for subsystem clock Main system clock frequency 1-10 MHz (3 MHz at 1.8 V, 10 MHz at 2.7 V) Subsystem clock frequency: 32.768 kHz CPU clock divider (1/1, 1/2, 1/8, 1/16) Idle (only CPU clock stops) Stop (System clock stops) 6 level 8 vector 8 internal interrupt 2 level 8 vector 8 external interrupt 45 I/O Pins * * * * * * * * * * 45 configurable I/O pins Overflow signal makes a system reset.

It has an on-chip OTP ROM instead of a masked ROM. The EPROM is accessed by serial data format. The S3P8245/P8249 is fully compatible with the S3C8248/C8245/C8247/C8249, both in function and in pin configuration. Because of its simple programming requirements, the S3P8245/P8249 is ideal as an evaluation chip for the S3C8248/C8245/C8247/C8249. 21-1 S3P8245/P8249 OTP S3C8248/C8245/P8245/C8247/C8249/P8249 Figure 21-1.
