■ DESCRIPTIONS
The S1C17801 is a high performance and compact 16-bit RISC application specific controller (ASC). It is suitable for
various products that require analog inputs, display and interfaces for connection, such as healthcare goods, sensor
systems, alarms, home electric appliance (rice cookers, microwave ovens and remote controllers).
The S1C17801 consists of a S1C17 16-bit compact RISC CPU Core, a 128K-byte Flash EEPROM, a 4K + 2K-byte RAM,
a 10-bit ADC with eight analog input channels, a USB FS-device controller, a PWM control capture timer/counter, an
infrared remote controller, serial interfaces (UART with IrDA 1.0, SPI, I²C, and I²S), an RTC driven with an independent
power supply, 16-bit and 8-bit timers, a watchdog timer, a NAND Flash card interface, an external bus with an SRAM
controller, GPIO ports and an STN LCD controller with built-in VRAM.
The LCD controller supports an external VRAM to display using a large size STN LCD panel. It also supports an LCD
driver DMA function to interface with an EPSON S1D15xxx built-in RAM LCD driver and a driver with an SPI.
The USB FS-device controller may be used not only for communication with PCs but also for on-board firmware update.
The S1C17801 provides a 16 bits × 16 bits + 32 bits MAC (multiply and accumulate) instruction to implement a DSP
function. Furthermore, an external audio ADC/DAC may be connected via the built-in I²S interface, this makes it possible
to input/output ADPCM sound/voice data.
The S1C17801 has adopted the EPSON SoC (System on Chip) design technology using 0.35 μm mixed analog low power
CMOS process.
