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.
