With features such as, LCD direct drive capability, 8-bit timer/counter, and watch timer, the KS57C2302/C2304 offers an excellent design solution for a wide variety of applications that require LCD functions. Up to 16 pins of the 64-pin QFP package, it can be dedicated to I/O. Four vectored interrupts provide fast response to internal and external events. In addition, the KS57C2302/C2304 's advanced CMOS technology provides for low power consumption and a wide operating voltage range. OTP The KS57C2302/C2304 microcontroller is also available in OTP (One Time Programmable) version, KS57P2304 . The KS57P2304 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The KS57P2304 is comparable to KS57C2302/C2304, both in function and in pin configuration. www.DataSheet4U.com 1-1 DataSheet 4 U .com www.DataSheet4U www.DataSheet4U.com 4U.com www.DataSheet4U.com PRODUCT OVERVIEW KS57C2302/C2304/P2304 MICROCONTROLLER FEATURES Memory — 288 × 4-bit RAM — 2048 × 8-bit ROM (KS57C2302) — 4096 × 8-bit ROM (KS57C2304) I/O Pins — Input only: 4 pins — I/O: 12 pins — Output: 8 pins sharing with segment driver outputs LCD Controller/Driver — Maximum 16-digit LCD direct drive capability — 32 segment, 4 common pins — Display modes: Static, 1/2 duty (1/2 bias) 1/3 duty (1/2 or 1/3 bias), 1/4 duty (1/3 bias) 8-Bit Basic Timer — Programmable interval timer — Watchdog timer 8-Bit Timer/Counter — Programmable 8-bit timer — External event counter — Arbitrary clock frequency output Watch Timer — Real-time and interval time measurement — Four frequency outputs to BUZ pin — Clock source generation for LCD Bit Sequential Carrier — Support 16-bit serial data transfer in arbitrary format Package Type — 64-pin QFP Oscillation Sources — Crystal, ceramic, or RC for main system clock — Crystal or external oscillator for subsystem clock — Main system clock frequency: 4.19 MHz (typical) — Subsystem clock frequency: 32.768 kHz — CPU clock divider circuit (by 4, 8, or 64) Interrupts — Two internal vectored interrupts — Two external vectored interrupts — Two quasi-interrupts Memory-Mapped I/O Structure — Data memory bank 15 Two Power-Down Modes — Idle mode (only CPU clock stops) — Stop mode (main or sub system oscillation stops) www.DataSheet4U.com Instruction Execution Times Operating Temperature — – 40 °C to 85 °C Operating Voltage Range — 0.95, 1.91, 15.3 µs at 4.19 MHz (main) — 122 µs at 32.768 kHz (subsystem) — 2.0 V to 5.5 V at 4.19 MHz — 1.8 V to 5.5 V at 3 MHz 1-2 DataSheet 4 U .com www.DataSheet4U www.DataSheet4U.com 4U.com www.DataSheet4U.com KS57C2302/C2304/P2304 MICROCONTROLLER PRODUCT OVERVIEW BLOCK DIAGRAM BASIC TIMER INT0, INT1,INT2 RESET WATCH TIMER P2.3/BUZ Xin XTin Xout XTout P1.3/TCL0 P2.0/TCLO0 8-BIT TIMER/ COUNTER 0 INTERRUPT CONTROL BLOCK CLOCK INSTRUCTION REGISTER LCD DRIVER/ CONTROLLER P6.0–P6.3 / KS0–KS3 I/O PORT 6 INTERNAL INTERRUPTS INSTRUCTION DECODER ARITHMETIC AND LOGIC UNIT PROGRAM COUNTER BIAS VLC0-VLC2 LCDCK/P3.0 LCDSY/P3.1 COM0-COM3 SEG0-SEG23 P8.0-P8.7/ SEG24-SEG31 PROGRAM STATUS WORD INPUT PORT 1 STACK POINTER I/O PORT 2 P8.0–P8.7 SEG24–SEG31 OUTPUT PORT 8 P1.0 / INT0 P1.1 / INT1 P1.2 / INT2 P1.3 / TCL0 P2.0 / TCLO0 P2.1 P2.2 / CLO P2.3 / BUZ P3.0 / LCDCK P3.1 / LCDSY P3.2 P3.3 www.DataSheet4U.com 288 x 4-BIT DATA MEMORY 2/4 K BYTE PROGRAM MEMORY I/O PORT 3 Figure 1-1.
