Data Sheet

OXU140CM

USB On-The-Go Full Speed Host, High Speed Peripheral

with Multi-Storage Interface

Features

Single‐chip USB OTG full‐speed host and high‐speed peripheral

controller

Reduces system cost and board space

Minimizes system design complexity and power

Simultaneous USB host, peripheral, and

CE‐ATA/MMC/SD interface operation

USB peripheral to CE‐ATA/MMC/SD bridging

Compatible with the USB 2.0 and OTG specifications

CE‐ATA 1.1 command support with built‐in flow control

MMC 4.1 compatible

Configurable 1‐/4‐/8‐bit data bus at up to 48 MHz clock

frequency

Dual‐voltage (3.3 V and 1.8 V) I/O support

Integrated smart clock control for reduced power

consumption

3.3 V power supply, flexible I/O voltage of 1.65 V to 3.6 V

(LVCMOS/TTL) to interface to a wide range of MCUs

Low‐power sleep mode to minimize power consumption when

not in use

Integrated on‐chip charge pump, supports up to 100 mA of

current, enables support for broad range of USB devices

Packaging

8 × 8 mm BGA, 100 ball, RoHS compliant

14 × 14 mm LQFP, 128 pin, RoHS compliant

16‐bit memory mapped interface can gluelessly interface to most

popular microprocessors and DSPs

Fast microprocessor access cycle and double/multi buffering

support for all four types of USB transfers

Two DMA (slave) channel support for peripheral controller and

CE‐ATA/MMC/SD controller lowers CPU utilization

Integrated PLL supports external crystal or crystal oscillators of

12 MHz or 30 MHz, for system flexibility
