- Low Current Consumption
- High Speed Operation in Low Voltage DESCRIPTION The S1C63656 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU, ROM (6,144 words × 13 bits), RAM (1,024 words × 4 bits), mult iply-divide circuit, serial interface, watchdog timer, programmable timer, time base counters (2 systems), an LCD driver that can drive a maximum 38 segments × 4 commons, sound generator, R/f converter and stepping mo tor driver built-in. The S1C63656 features low current consumption, this makes it suitable for battery driven clocks and watches with temperature and humidity measurement functions. FEATURES OSC1 oscillation circuit 32.768 kHz (Typ.) crystal oscillation circuit OSC3 oscillation circuit 4 MHz (Max.) ceramic (2 MHz Max. when OSC3 is used as the R/f converter operating clock), 1.1 MHz (Typ.) CR oscillation circuit or not used (*1) Instruction set Basic instruction: 46 types (411 instructions with all) Addressing mode: 8 types Instruction execution time During operation at 32.768 kHz: 61 μsec 122 μsec 183 μsec During operation at 4 MHz: 0.5 μsec 1 μsec 1.5 μsec ROM capacity Code ROM: 6,144 words × 13 bits Data ROM: 1,024 words × 4 bits RAM capacity Data memory: 1,024 words × 4 bits Display memory: 48 words × 4 bits Input port 8 bits (Pull-down resistors may be supplemented *1) Output port 4 bits (It is possible to switch the 2 bits to special output *2) I/O port 8 bits (It is possible to switch the 4 bits to serial I/F input/output *2) Serial interface 1 port (8 -bit clock synchronous system) LCD driver 38 segments × 4 or 3 commons (*2) Time base counter Clock timer Stopwatch timer (1/1000 sec, with direct key input function) Programmable timer 8-bit PWM × 2 ch. or 16-bit PWM × 1 ch. (*2) Watchdog timer Built-in Sound generator With envelope and 1-shot output functions R/f converter 2 ch., CR oscillation type, 20-bit counter Supports resistive humidity sensors Multiply-divide circuit 8-bit accumulator × 1 ch. Multiplication: 8 bits × 8 bits -> 16-bit product Division: 16 bits ÷ 8 bits -> 8-bit quotient and 8-bit remainder Stepping motor driver 2 ch., a clock or watch controller can be implemented Supply voltage detection (SVD) Criteria voltages: 1.85–2.90 V (1.13–1.64 V when OSC3 is not used) are selectable (*2) External interrupt Input port interrupt: 2 systems Internal interrupt Clock timer interrupt: 5 systems Stopwatch timer interrupt: 4 systems Programmable timer interrupt: 4 systems Serial interface interrupt: 1 system R/f converter interrupt: 2 systems Motor driver interrupt: 2 systems Power supply voltage 2.4 to 3.6 V: Max. 4 MHz operation (when OSC3 is used) 1.1 to 3.6 V: 32 kHz operation (when OSC3 is not used) Operating temperature range -20 to 70°C
Current consumption (Typ.) Low-speed operation (OSC1 = 32 kHz crystal oscillation): During HALT 3.0 V (LCD ON) 0.60 µA During operation 3.0 V (LCD ON) 2.50 µA High-speed operation (OSC3 ceramic oscillation): During operation 3.0 V (LCD ON) 1.0 mA Shipment form QFP20-144pin (plastic) or chip *1: Can be selected with mask option *2: Can be selected with software
