1 Outline

The S1C33210 is a Seiko Epson original 32-bit microcomputer. It features high speed, low power consumption,
and low-voltage operation, and is ideal for portable products that require high-speed data processing.
The S1C33210 consists of an S1C33000 32-bit RISC type CPU as its core, peripheral circuits including a bus control
unit, DMA controller, interrupt controller, timers, serial interface, and A/D converter, and also mobile access
interface and RAM. A high-speed oscillation circuit and PLL, and a low-speed clock input circuit, are also included,
supporting advanced operation, power-saving operation, and high-speed realtime clock functions. Use of the internal
MAC (multiplication and accumulation) function in combination with the A/D converter also facilitates the design of
systems requiring DSP functions, such as speech recognition and synthesis applications.
Table 1.1 shows the various models. The package and data bus interface vary according to the model.
