1 Outline
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.
