21-S3-C831B/P831B-062003 USER'S MANUAL www.DataSheet4U.com S3C831B/P831B 8-Bit CMOS Microcontroller Revision 1 S3C831B/P831B 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. Among the major CPU features are: — 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 of four CPU clocks) can be assigned to specific interrupt levels. S3C831B MICROCONTROLLER www.DataSheet4U.com The S3C831B single-chip microcontroller are fabricated using the highly advanced CMOS process. Its design is based on the powerful SAM88RC CPU core. Stop and idle (power-down) modes were implemented to reduce power consumption. The S3C831B is a microcontroller with a 64K-byte mask-programmable ROM embedded. The S3P831B is a microcontroller with a 64K-byte one-time-programmable ROM embedded. Using the SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC CPU core: — Large number of programable I/O ports (Total 72 pins) — PLL frequency synthesizer — 16-bits intermediate frequency counter — Two synchronous SIO modules — Two 8-bit timer/counters — One 16-bit timer/counter — Low voltage reset — A/D converter with 8 selectable input pins OTP The S3C831B microcontroller is also available in OTP (One Time Programmable) version, S3P831B. The S3P831B microcontroller has an on-chip 64K-byte one-time-programmable EPROM instead of masked ROM. The S3P831B is comparable to S3C831B, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW S3C831B/P831B FEATURES CPU • SAM88RC CPU core Two 8-bit Serial I/O Interface • • • 8-bit transmit/receive mode 8-bit receive mode Selectable baud rate or external clock source Memory • • 2576-byte internal register file (including LCD display RAM) 64K-byte internal program memory area PLL Frequency Synthesizer • VIN level: 300mVpp (minimum) • • AMVCO range: 0.5 MHz–30 MHz (3-bit counter added) FMVCO range: 30 MHz–150 MHz Instruction Set • • 78 instructions Idle and Stop instructions 72 I/O Pins • • 32 normal I/O pins 40 pins sharing with LCD segment signals 16-Bit Intermediate Frequency (IF) Counter • VIN level: 300mVPP (minimum) • • AMIF range: 100 kHz–1 MHz FMIF range: 5 MHz–15 MHz Interrupts • • 8 interrupt levels and 17 internal sources Fast interrupt processing feature LCD Controller/Driver • • • 40 segments and 4 common terminals 4/3/2 common and static selectable Internal or external resistor circuit for LCD bias 8-Bit Basic Timer • Watchdog timer function • www.DataSheet4U.com 4 kinds of clock source Timer/Counter 0 • • • Programmable 8-bit internal timer External event counter function PWM and capture function Low Voltage Reset (LVR) • • Low voltage check to make system reset VLVR: 2.4V, 3.7 V selectable Two Power-Down Modes • • Idle mode: only CPU clock stops Stop mode: system clock and CPU clock stop Timer/Counter 1 • • Programmable 8-bit interval timer External event counter function Oscillation Source • Crystal or ceramic for system clock (fx) Timer/Counter 2 • • Programmable 16-bit interval timer External event counter function Instruction Execution Time • 444 ns at 9.0 MHz (minimum) Operating Temperature Range • –25 °C to +85 °C Watch Timer • • Interval Time: 50ms, 0.5s, 1.0s at 4.5 MHz 1/1.5/3/6 kHz buzzer output selectable Operating Voltage Range • • • 2.2V to 5.5V at 0.4 MHz – 4.5 MHz 4.0 V to 5.5 V at 0.4 MHz–9.0 MHz 2.5V to 3.5V, 4.5 V to 5.5 V in PLL/IFC block Analog to Digital Converter • • 8-channel analog input 8-bit conversion resolution Package Type • 100-QFP-1420C, 100-TQFP-1414 1-2 S3C831B/P831B PRODUCT OVERVIEW BLOCK DIAGRAM P1.0-P1.7/ RESET INT0-INT7 XIN XOUT P0.2/T0CAP P0.1/T0CLK P0.3/T0OUT/T0PWM P0.4/T1CLK P0.5/T1OUT P0.6/T2CLK P0.7/T2OUT P3.1/SCK0 P3.2/SO0 P3.3/SI0 P3.4/SCK1 P3.5/SO1 P3.6/SI1 Watchdog Timer P3.0/BUZ COM0-3 P8.7-P4.0/SEG0-39 BIAS VLC0 -VLC2 VCOAM VCOFM EO0/EO1 AMIF FMIF P2.0-P2.7/AD0-AD7 CE P0.0 P0.1/T0CLK P0.2/T0CAP P0.3/T0OUT/T0PWM P0.4/T1CLK P0.5/T1OUT P0.6/T2CLK P0.7/T2OUT P1.0/INT0 P1.1/INT1 P1.2/INT2 P1.3/INT3 P1.4/INT4 P1.5/INT5 P1.6/INT6 P1.7/INT7 P2.0/AD0 P2.1/AD1 P2.2/AD2 P2.3/AD3 P2.4/AD4 P2.5/AD5 P2.6/AD6 P2.7/AD7 P3.0/BUZ P3.1/SCK0 P3.2/SO0 P3.3/SI0 P3.4/SCK1 P3.5/SO1 P3.6/SI1 P3.7 P4.0/SEG39 P4.1/SEG38 P4.2/SEG37 P4.3/SEG36 P4.4/SEG35 P4.5/SEG34 P4.6/SEG33 P4.7/SEG32 P5.0/SEG31 P5.1/SEG30 P5.2/SEG29 P5.3/SEG28 P5.4/SEG27 P5.5/SEG26 P5.6/SEG25 P5.7/SEG24 P6.0/SEG23 P6.1/SEG22 P6.2/SEG21 P6.3/SEG20 P6.4/SEG19 P6.5/SEG18 P6.6/SEG17 P6.7/SEG16 P7.0/SEG15 P7.1/SEG14 P7.2/SEG13 P7.3/SEG12 P7.4/SEG11 P7.5/SEG10 P7.6/SEG9 P7.7/SEG8 OSC 8-Bit Timer/ Counter0 8-Bit Timer/ Counter1 Port 1 16-Bit Timer/ Counter2 SIO 0 Port 2 SIO 1 Port 0 I/O Port and Interrupt Control Basic Timer Port 3 Watch Timer SAM88RC Core www.DataSheet4U.com LCD Driver/ Controller Port 4 PLL Synthesizer IF Counter Port 5 8-Bit ADC AVDD P8.0/SEG7 P8.1/SEG6 P8.2/SEG5 P8.3/SEG4 P8.4/SEG3 P8.5/SEG2 P8.6/SEG1 P8.7/SEG0 LVREN LVRSEL 64K-byte ROM 2576-byte Register File Port 6 Port 8 Port 7 Low Voltage Reset TEST1 TEST2 VDD VDDPLL0 VDDPLL1 VSS VSSPLL Figure 1-1.
