■ DESCRIPTIONS
The S1C17501 is a high performance and compact 16-bit RISC application specific controller (ASC). It is suitable for
various products that require analog inputs and interfaces for connection, such as healthcare goods, sensor systems,
alarms, home electric appliance (rice cookers, microwave ovens and remote controllers).
The S1C17501 consists of a S1C17 16-bit compact RISC CPU Core, a 128K- or 96K-byte Flash EEPROM, a 4K-byte
RAM, a 2K-byte battery backup 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 and GPIO ports.
The USB FS-device controller may be used not only for communication with PCs but also for on-board firmware update.
The S1C17501 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 S1C17501 has adopted the EPSON SoC (System on Chip) design technology using 0.35 μm mixed analog low power
CMOS process.
