S3P8849

m o .c U 4 t e e h S a at PRODUCT OVERVIEW .D w SAM87 w PRODUCT FAMILY wSamsung's SAM87 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide S3C8847/C8849/P8849 PRODUCT OVERVIEW 1 range of integrated peripherals, and various mask-programmable ROM sizes. Important CPU features include: — Efficient register-oriented architecture — Selectable CPU clock sources — Release of Idle and Stop power-down modes by interrupt — Built-in basic timer circuit 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. S3C8847/C8849/P8849 MICROCONTROLLERS The S3C8847 microcontroller has a 24-Kbyte on-chip program memory and the S3C8849 has a 32-Kbyte. Both chips have a 272-byte general-purpose internal register file. The interrupt structure has nine interrupt sources with nine interrupt vectors. The CPU recognizes seven interrupt priority levels. Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the S3C8847/C8849/P8849 microcontrollers suitable for use in color television and other types of screen display applications: — Four programmable I/O ports (26 pins total: 16 general-purpose I/O pins; 10 n-channel, open-drain output pins) — 4-bit resolution A/D converter (4 channels) — 14-bit PWM o...
