Overview
I.1 Overview
The S1C33L17 is a high cost performance 32-bit RISC controller for specific applications that require a lot of
general-purpose I/O, a powerful PWM Timer/Counter function, several serial interfaces including USB-FS device
controller, an ADC and a LCD display system, such as middle-low range electronic dictionaries and label writers/
printers.
The S1C33L17 consists of a 32-bit RISC CPU-Core, generic DMA controller, USB-FS device controller, PWM
control Timer/Counter, several interfaces (SIO including IrDA1.0 and ISO7816-3 protocol, SPI and I2S), ADC,
RAM/Shared IVRAM and RTC implemented by EPSON SoC design technology using 0.18 m Mixed Analog
Low CMOS Process.

oscillatorCircuit/PLL
osC3oscillatorCircuit
Crystal oscillation:
5 MHz min. to 48 MHz max.
Ceramic oscillation:
5 MHz min. to 48 MHz max.
External clock input: 5 MHz min. to 48 MHz max.
A 48 MHz clock source with 0.25% of accuracy should be connected for using the USB function.
