KS57C2916/P2916 MICROCONTROLLER 1 PRODUCT OVERVIEW PRODUCT OVERVIEW OVERVIEW The KS57C2916 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With an up-to-704-dot LCD direct drive capability, and flexible 8-bit timer/counter, the KS57C2916 offers an excellent design solution for a mid-end LCD game. Up to 8 pins of the 80-pin QFP package can be dedicated to I/O. Six vectored interrupts provide fast response to internal and external events. In addition, the KS57C2916's advanced CMOS technology provides for low power consumption. OTP The KS57C2916 microcontroller is also available in OTP (One Time Programmable) version, KS57P2916. KS57P2916 microcontroller has an on-chip 16K-byte one-time-programable EPROM instead of masked ROM. The KS57P2916 is comparable to KS57C2916, both in function and in pin configuration. 1-1 PRODUCT OVERVIEW KS57C2916/P2916 MICROCONTROLLER FEATURES Memory • 256 × 4-bit RAM (excluding LCD display RAM) • 16,384 × 8-bit ROM Memory-Mapped I/O Structure • Data memory bank 15 Power-Down Modes 8 I/O Pins • Idle mode (only CPU clock stops) • • Stop mode (main system oscillation stops) • Sub system clock stop mode I/O: 8 pins LCD Controller/Driver 44 segments and 16 common terminals Oscillation Sources (8, 12 and 16 common selectable) • Crystal, ceramic, or RC for main system clock • Internal resistor circuit for LCD bias • Crystal oscillator for subsystem clock • Voltage doubler • • All dot can be switched on/off Main system clock frequency: 4.19 MHz (typical) • Subsystem clock frequency: 32.768 kHz • CPU clock divider circuit (by 4, 8, or 64) • 8-bit Basic Timer • 4 interval timer functions • Watch-dog timer 8-bit Timer/Counter • Programmable 8-bit timer • Arbitrary clock output (TCLO0) • Inverted clock output (TCLO0) Instruction Execution Times • 0.95, 1.91, 15.3 µs at 4.19 MHz (main) • 122 µs at 32.768 kHz (subsystem) Operating Temperature • – 40 °C to 85 °C Watch Timer Operating Voltage Range • Time interval generation: 0.5 s, 3.9 ms at 32768 Hz • • Four frequency outputs to BUZ pin and BUZ pin • Clock source generation for LCD Interrupts • Two internal vectored interrupts • Four external vectored interrupts • Two quasi-interrupts 1-2 2.2 V to 3.4 V (0.4 MHz to 4.19 MHz) Package Type • 80-pin QFP or pellet KS57C2916/P2916 MICROCONTROLLER PRODUCT OVERVIEW BLOCK DIAGRAM RESET P0.3/BUZ/K3 P0.2/CLO/ BUZ /K2 P0.1/TCLO0 /K1 I/O PORT 0 INTERRUPT CONTROL BLOCK Xin XTin Xout XTout CLOCK INSTRUCTION REGISTER P0.0/TCLO0/K0 INTERNAL INTERRUPT P1.3/INT P1.2/INT2 P1.1/INT1 I/O PORT 1 INSTRUCTION DECODER P1.0/INT0 8-BIT TIMER/ COUNTER ARITHMETIC AND LOGIC UNIT 256 x 4-BIT DATA MEMORY PROGRAM COUNTER PROGRAM STATUS WORD STACK POINTER BASIC TIMER WATCH-DOG TIMER WATCH TIMER VOLTAGE DOUBLER LCD DRIVER/ CONTROLLER BIAS CA CB SEG0-SEG43 COM0-COM15 VLC0 16K BYTES PROGRAM MEMORY Figure 1-1.

Because of its simple programming requirements, the KS57P2916 is ideal for use as an evaluation chip for the KS57C2916. 15-1 KS57C2916/P2916 MICROCONTROLLER 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 SEG40 SEG39 SEG38 SEG37 SEG36 SEG35 SEG34 SEG33 SEG32 SEG31 SEG30 SEG29 SEG28 SEG27 SEG26 SEG25 KS57P2916 OTP SEG41 SEG42 SEG43 P1.3/INT4 P1.2/INT2 P1.1/INT1 P1.0/INT0 P0.3/BUZ/K3 P0.2/CLO/ BUZ /K2 SDAT /P0.1/TCLO 0 /K1 SCLK /P0.0/TCLO0/K0 VDD/VDD VSS/VSS Xout Xin VPP/TEST XTin XTout RESET / RESET KS57P2916 (TOP VIEW) 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 COM14 COM13 COM12 COM11 COM10 COM9 COM8 COM7 COM6 COM5 COM4 COM3 COM2 COM1 COM0 SEG0 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 CA CB VLC0 BIAS COM15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Figure 15-1.
