S1C17W18 (rev1.2) 16-bit Single Chip Microcontroller ■ DESCRIPTIONS ● Low voltage operation from 1.2 V with a single alkaline or silver oxide button battery. ● Ultra low standby power consumption (0.3 µA during HALT state in super economy mode) ● Embedded A/D converter to support various sensing applications The S1C17W18 is a 16-bit MCU that features low-voltage operation from 1.2 V even though Flash memory is included. The embedded high-efficiency DC-DC converter generates the constant-voltage to drive the IC with lower power consumption than 4-bit MCUs. This IC includes a real-time clock, a stopwatch, an LCD driver, a temperature sensor, an A/ D converter, and a PWM timer capable of being used to generate drive waveforms for a motor driver as well as a highperformance 16-bit CPU. It is suitable for battery-driven applications that require an LCD display and a temperature measurement function. ■ FEATURES Model CPU CPU core Other Embedded Flash memory Capacity Erase/program count Other Embedded RAM Capacity Embedded display RAM Capacity Clock generator (CLG) System clock source System clock frequency (operating frequency) IOSC oscillator circuit (boot clock source) OSC1 oscillator circuit OSC3 oscillator circuit EXOSC clock input Other I/O port (PPORT) Number of general-purpose I/O ports Number of input interrupt ports Number of ports that support universal port multiplexer (UPMUX) Timers Watchdog timer (WDT) Real-time clock (RTCA) 16-bit timer (T16) S1C17W18 Seiko Epson original 16-bit RISC CPU core S1C17 On-chip debugger 128K bytes (for both instructions and data) 1,000 times (min.) * Programming by the debugging tool ICDmini Security function to protect from reading/programming by ICDmini On-board programming function using ICDmini Flash programming voltage can be generated internally. 8K bytes 96 bytes 4 sources (IOSC/OSC1/OSC3/EXOSC) 1.1 MHz (max.)

The pin function must be switched via software to assign another signal (see the “I/O Ports” chapter). I/O: I = Input O = Output I/O = Input/output P = Power supply A = Analog signal Hi-Z = High impedance state Initial state: I (Pull-up) = Input with pulled up I (Pull-down) = Input with pulled down Hi-Z = High impedance state O (H) = High level output O (L) = Low level output Tolerant fail-safe structure: ✓ = Over voltage tolerant fail-safe type I/O cell included (see the “I/O Ports” chapter) The over voltage tolerant fail-safe type I/O cell allows interfacing without passing unnecessary current even if a voltage exceeding VDD is applied to the port. Also unnecessary current is not consumed when the port is externally biased without supplying VDD. ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ – – ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓
