| 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 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. OTP 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 masked ROM. The S3P8837 is comparable to S3C8835/C8837, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW S3C8835/C8837/P8837 FEATURES CPU * SAM87 CPU core Pulse Width Modulation Module * * * 14-bit PWM with one-channel output (push-pull type) PWM counter and data capture input pin Frequency: 5.859 kHz to 23.437 kHz with a 6-MHz CPU clock Memory * * 16-K byte (S3C8835) or 24K- byte (S3C8837) internal program memory 272-byte general-purpose register area On-Screen Display (OSD) Instruction Set * * 78 instructions IDLE and STOP instructions added for powerdown modes * * * * * * Interrupts * * * 7 interrupt sources with 6 vectors 6 interrupt levels Fast interrupt processing for select levels * General I/O * * * Four I/O ports (26 pins total) Six open-drain pins for up to 6-volt loads Two open-drain pins for up to 5-volt loads * * * Video RAM: 252 x 12 bits Character generator ROM: 256 x 18 x 16 bits (256 display characters: fixed: 2, variable: 254) 252 display positions (12 rows x 21 columns) 16-dot x 18-dot character resolution 16 different character sizes Eight character colors Vertical direction fade-in/fade-out control Eight colors for character and frame background Halftone control signal output; selectable for individual characters Synchronous polarity selector for H-sync and V-sync input Instruction Execution Time * 750 ns (minimum) with an 8-MHz CPU clock Oscillator Frequency * * 5-MHz to 8-MHz external crystal oscillator Maximum 8-MHz CPU clock 8-Bit Basic Timer * * Three selectable internal clock frequencies Watchdog or oscillation stabilization function Operating Temperature Range * - 20C to + 85C Timer/Counters * * One 8-bit timer/counter (T0) with three internal clocks and interval timer mode.
