The S1C33L03 is a Seiko Epson original 32-bit microcomputer with a built-in LCD controller. It features high speed, low power and low-voltage operation and is most suitable for portable equipment that needs display function, such as information terminals, E-mail terminals, electronic dictionaries.

The S1C33L03 consists of the S1C33000 32-bit RISC type CPU as the core, a bus control unit, a DMA controller, an interrupt controller, an LCD controller, an SDRAM controller, timers, serial interface circuits, an A/D converter, ROM and RAM.

The S1C33L03 provides a DSP function, by using the internal MAC (multiplication and accumulation) operation function with the A/D converter, it makes it possible to design simply speech recognition and voice synthesis systems.
