The EPSON S1C17W18F101100 is a low-power 16-bit microcontroller featuring an S1C17 core running at 4.2MHz. It integrates an LCD controller, PWM, RFC, and watchdog timer, making it a versatile choice for display-centric embedded systems. With 96KB flash and 8KB RAM, it supports complex firmware in a 128-TQFP package, operating from 1.2V to 3.6V.

  • Ultra-low voltage operation (1.2V) – Enables direct battery operation with minimal power conversion losses.
  • Integrated LCD driver – Reduces external components and simplifies display interface design.
  • Rich peripheral set (PWM, RFC, WDT) – Provides flexibility for motor control, wireless triggering, and system supervision.
  • Wide temperature range (-40°C to 85°C) – Suitable for industrial and automotive environments.

Portable Medical Devices

The low 1.2V operation and LCD driver enable compact glucose meters and thermometers with direct display readouts.

Battery-Powered Sensors

With 96KB flash and 8KB RAM, it can log sensor data while the PWM and RFC modules handle periodic wake-ups and wireless triggers.

Industrial Control Panels

The 128-TQFP package provides enough I/O for keypads and indicators, while the WDT ensures reliable operation in noisy environments.

Smart Home Thermostats

LCD output and low power consumption allow always-on temperature display with minimal battery drain.

Wearable Fitness Trackers

The small footprint and 1.2V operation support slim designs, and the RFC module enables simple wireless communication.

Automotive Aftermarket Gauges

Operating from -40°C to 85°C, it can drive segmented LCDs in dashboards with PWM for backlight control.
