ML671000

FEDL671000-02 1 Semiconductor ML671000 GENERAL DESCRIPTION This version: Jul. 2001 Previous version: Jul. 2001 OKI’s CMOS 32-Bit Single-Chip Microcontroller with Built-in USB Device Controller The ML671000 is a high-performance CMOS 32-bit microcontroller combining a RISC based, 32-bit CPU core the ARM7TDMITM - 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. FEATURES (1) RISC 32-bit CPU (ARM7TDMI) Executable 32-bit instructions and 16-bit instructions General registers: 32-bit × 31 registers Built-in multiplier Little-endian format Internal RAM : 4K bytes External ROM, RAM, I/O : 26M bytes External DRAM : 32M bytes I/O pins: 64 pins (I/O directions are specified at the bit level) 16-bit flexible timer × 2ch (auto-reload, compare-output, PWM, capture modes) 16-bit auto-reload timer × 2ch 12-bit watchdog timer UART (16550A equivalent) × 1ch, UART/synchronous serial × 1ch USB1.1 compliant, support full-speed (12 Mbps) Transmission type: control, bulk, isochronous, interrupt Remote wakeup function Adaptable to USB bus powered devices...
