OKI’s CMOS 32-Bit Single-Chip Microcontroller with Built-in USB Device Controller
GENERAL DESCRIPTION
The ML671000 is a high-performance CMOS 32-bit microcontroller combining a RISC based, 32-bit CPU core -
the ARM7TDMI^TM - with USB device controller, memory and peripherals.
The built-in USB device controller which is based on USB1.1 Full-speed (12 Mbps) makes interface with PCs or
other devices by USB. The ML671000, which provides the 32-bit data processing capability and built-in
peripheral functions performed by UART, serial ports, 16-bit timers, a DMA controller, and a memory controller,
is a single-chip microcontroller idealy suited to PC peripheral equipment and communication terminal control
applications.
