S3P80E5

S3C80E5/P80E5/C80E7/P80E7 (Preliminary Spec) 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. Important CPU features include: — 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 six CPU clocks) can be assigned to specific interrupt levels. S3C80E5/C80E7 MICROCONTROLLER The S3C80E5/C80E7 single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process, based on Samsung’s newest CPU architecture. The S3C80E5/C80E7 is the microcontroller which has 16/24-Kbyte mask-programmable ROM. The S3P80E5/P80E7 is the microcontroller which has 16/24-Kbyte one-time-programmable EPROM. Using a proven modular design approach, Samsung engineers developed the S3C80E5/C80E7 by integrating the following peripheral modules with the powerful SAM87 core: — Four programmable I/O ports, including three 8-bit ports and one 2-bit port, for a total of 26 pins. — Internal LVD circuit and twelve bitprogrammable pins for external interrupts. — One 8-bit basic timer for oscillation stabilization ...
