S1C33210 (Mobile Access Gateway IC)
32-bit Single Chip Microcomputer
● 32-bit RISC CPU
● HDLC Controller
● Three Serial I/O (SIO) Interfaces
● 8K Bytes of Built-in RAM
● Multiply-and-accumulate Instructions
■ DESCRIPTION
The S1C33210 single-chip microcomputer consists of the S1C33000 CMOS 32-bit RISC CPU core plus an HDLC
controller, three serial I/O (SIO) interfaces, 8K bytes 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.
