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
• V_CC=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
