S3C8835/C8837/P8837 PRODUCT OVERVIEW 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 timer function - One 8-bit timer/counter (T0) with interval timer - One 8-bit general-purpose timer/counter (TA) with prescalers - On-screen display (OSD) with a wide range of programmable Features including halftone control signal output The S3C8835/C8837 are available in a versatile 42-pin SDIP package. The S3C8835/C8837 microcontroller is also available in OTP (One Time Programmable) version, S3P8837. S3P8837 microcontroller has an on-chip 24K-byte one-time-programmable EPROM instead of...
