PRODUCT OVERVIEW
S3C8-SERIES MICROCONTROLLES
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.
S3C821A/P821A MICROCONTROLLER
The S3C821A/P821A single-chip CMOS microcontroller is fabricated using the highly advanced CMOS process, based on Samsung's newest CPU architecture. The S3C821A is a microcontroller with a 48-Kbyte mask-programmable ROM embedded. The S3P821A 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.
OTP
The S3P821A 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.
