The EPSON S1C17W15D001000 is a low-power 16-bit MCU designed for compact embedded systems. It operates from 1.2V to 3.6V and runs at 4.2MHz, featuring 64KB flash and 4K x 8 RAM. This die-form controller integrates LCD drive, PWM, RFC, and watchdog timer functions, making it ideal for portable instrumentation and battery-operated devices.

  • Ultra-low voltage operation (1.2V) – enables single-cell battery designs.
  • Integrated LCD driver – reduces external components and PCB space.
  • Bare die package – flexible for custom hybrid assemblies.
  • Wide temperature range (-40°C to 85°C) – reliable in harsh environments.

Battery-Powered Sensor Nodes

The 1.2V minimum supply voltage allows direct operation from a single-cell battery, extending runtime in IoT sensors.

LCD Display Controllers

Integrated LCD driver circuitry simplifies bill of materials for portable meters and medical devices.

Low-Frequency PWM Control

The 4.2MHz clock with PWM and RFC modules enables precise motor speed control in small appliances.

Watchdog-Safe Industrial Timers
