16-bit Single Chip Microcontroller with RTCH

The S7C17M11, from Epson is a low-power 16-bit microcontroller with on-chip Flash memory, a crystal unit, and a highly accurate real-time clock (RTC) with a temperature compensation function. Epson integrated a crystal unit into the S7C17M11 microcontroller package that allows to develop accurate timekeeping efficiently even under harsh environmental conditions, such as in outdoor meters.


  • Built-in high precision RTC with temperature compensation function (RTCH) (comes with a 32.768 kHz crystal resonator stacked into the package)
  • 128KB Flash ROM with read/write protection function, 8KB RAM
  • Equipped with a 30-segment × 8-common LCD driver
  • Achieve ultra-low current consumption, 2.25 μA when RTCH is running
  • Built-in smart card interface conforming to ISO7816-3 specification
  • Supports various serial interfaces (UART, SPI, I2C)
  • Built-in power supply switching circuit
