Preliminary

GENERAL DESCRIPTION

The ML60852 is a general purpose Universal Serial Bus (USB) device controller.

The ML60852 provde a USB serial interface engine, USB transceiver, FIFOs, control/status registers, application

interface circuit, and oscillation circuit thereby easily realizing a USB system. The ML60852 supports four types

of data transfer such as control transfer, bulk transfer, interrupt transfer and isochronous transfer, and also supports

five or six endpoints.

FEATURES

• USB1.1 compliant

• Supports full-speed (12 Mbps).

• Supports four types of transfer; control transfer, bulk transfer, interrupt transfer, and isochronous transfer.

• Endpoints: 5 to 6 endpoints

Control EP

Isochronous/bulk/interrupt EP 1 or 2

• Built-in FIFO for data storage

• A two-layer configuration of FIFO for each of EP1, EP2, EP4, and EP5

• DMA transfer is possible (EP1, EP2, EP4, and EP5).

• Supports bus-powered device.

The suspend condition is automatically detected and the low-power mode is activated. Normal operation is

automatically restarted when the resume condition is detected.

• Built-in USB transceiver circuit

• VCC=3.0 to 3.6 V

• Interface with 5 V circuit is possible. (Input: 5 V tolerant, output: TTL)

• Built-in 12 MHz oscillation circuit

• Package options:

44-pin plastic QFP or TQFP

56-pin plastic LGA
