DESCRIPTIONS
The S1C33205 is a CMOS 32-bit microcomputer composed of a CMOS 32-bit RISC core, RAM, DMA, timers, SIO, PLL and
other circuits. Featuring high-speed operation, low current consumption, and including a SDRAM controller, this
microcomputer allows direct connection of external SDRAM, making it ideal for use with PDAs and other portable devices. In
addition, since the microcomputer incorporates an A/D converter and PWM and is capable of multiply-accumulate operations,
digital signal processing such as speech synthesis processing can be accomplished with a single chip.
