DESCRIPTIONS
The SIC33210 single-chip microcomputer consists of the S1C33000 CMOS 32-bit RISC CPU core plus an HDLC controller,
three serial I/O (SIO) interfaces, 8 Kbytes of built-in RAM, a direct memory access (DMA) controller, timers, an analog
to-digital converter, and other components. The device features both high-speed operation and low power consumption. The
HDLC controller, serial I/O (SIO) interfaces, and other components necessary for mobile access make this device ideal for
data communications adapters, PDAs, and other portable information equipment. The multiply-and-accumulate instructions
and analog-to-digital converter support voice recognition, voice synthesis, and other forms of digital signal processing for use
in portable multimedia terminals.
