Features

Full-speed USB node device

Integrated USB transceiver

Supports 24 MHz oscillator circuit with internal 48

MHz clock generation circuit

Programmable clock generator

Serial Interface Engine (SIE) consisting of Physical

Layer Interface (PHY) and Media Access Controller

(MAC), USB Speciﬁcation 1.0 and 1.1 compliant

Control/Status register ﬁle

USB Function Controller with seven FIFO-based End-

points:

— One bidirectional Control Endpoint 0 (8 bytes)

— Three Transmit Endpoints (64 bytes each)

— Three Receive Endpoints (64 bytes each)

8-bit parallel interface with two selectable modes:

— Non-multiplexed

— Multiplexed (Intel compatible)

Enhanced DMA support

— Automatic DMA (ADMA) mode for fully CPU-inde-

pendent transfer of large bulk or ISO packets

— DMA controller, together with the ADMA logic, can

transfer a large block of data in 64-byte packets via

the USB

— Automatic Data PID toggling/checking and NAK

packet recovery (maximum 256x64 bytes of data =

16K bytes)

MICROWIRE/PLUS interface
