Features, Applications

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 six CPU clocks) can be assigned to specific interrupt levels.

The S3C821A/P821A single-chip CMOS microcontroller is fabricated using the highly advanced CMOS process, based on Samsung's newest CPU architecture. The is a microcontroller with a 48-Kbyte mask-programmable ROM embedded. The is a microcontroller with a 48-Kbyte one-time-programmable ROM embedded. Using a proven modular design approach, Samsung engineers have successfully developed the S3C821A/P821A by integrating the following peripheral modules with the powerful SAM8 core: Six programmable I/O ports, including five 8-bit ports and one 7-bit port, for a total of 47 pins. Twelve 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. Watch timer for real time. 4-input A/D converter Serial I/O interface The S3C821A/P821A is versatile microcontroller for cordless phone, pager, etc. They are currently available in 80-pin TQFP and 80-pin QFP package.

The is an OTP (One Time Programmable) version of the S3C821A microcontroller. The S3P821A microcontroller has an on-chip 48-Kbyte one-time-programmable EPROM instead of a masked ROM. The S3P821A is comparable to the S3C821A, both in function and in pin configuration.
