S3P8837

S3C8835/C8837/P8837 PRODUCT OVERVIEW 1 PRODUCT OVERVIEW SAM87 PRODUCT FAMILY Samsung's SAM87 family 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 — Release by interrupt of Idle and Stop power-down modes — 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 six CPU clocks) can be assigned to specific interrupt levels. S3C8835/C8837/P8837 The S3C8835 microcontroller has 16 K bytes of on-chip program memory and the S3C8837 has 24 K bytes. Both chips have a 272-byte general-purpose internal register file. The interrupt structure has seven interrupt sources with six interrupt vectors. The CPU recognizes six interrupt priority levels. Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the S3C8835/C8837/P8837 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; 8 n-channel, open-drain output pins) — 2 channel A/D converter (4-bit resolution) — 14-bit PWM output (one channels: push-pull type) — Basic timer (BT) with watchdog time...
