General-purpose microcontrollers support 5 V operation

Epson’s 16-bit microcontrollers with built-in Flash memory have proved to be a popular choice not only for small home applications but for mobile devices owing to their exceptionally low power consumption. Epson has been expanding and enhancing its S1C17 family of MCUs, which support operating voltages from 1.8 V to 5.5 V.

Key product features
1. Built-in circuits that will reduce the number of components in customers’ products, save board space, and shrink software development times

  • The built-in oscillator circuit is user selectable. In addition to 12 MHz and 16 MHz, customers can choose a 20 MHz circuit, the fastest in the S1C17 family.
  • 16 kB of self-programmable Flash memory and 2 kB of RAM
  • A universal port multiplexer (UPMUX) enables I/O pin assignments to be changed with software.
  • Fault tolerant/failsafe I/Os* prevent circuit failures and increases in current consumption from occurring when unnecessary current is flowing from another
    connected device with a higher supply voltage.
  • Analog-digital converter
  • Three types of serial interface
  • Infrared remote control output signal generator

 

2. Low-voltage and low-current consumption that extend battery life.
The S1C17M20 consumes a mere 0.5 μA of current in Sleep mode and supports supply voltages from 1.8 V to 5.5 V. It can be used for a wide range of applications in industrial products as well as in battery-operated consumer electronics and IoT devices.
