The ISP1504A1; ISP1504C1 (ISP1504x1) is a Universal Serial Bus (USB) On-The-Go
(OTG) transceiver that is fully compliant with Universal Serial Bus Specification Rev. 2.0,
On-The-Go Supplement to the USB 2.0 Specification Rev. 1.2 and UTMI+ Low Pin
Interface (ULPI) Specification Rev. 1.1.
The ISP1504x1 can transmit and receive USB data at high-speed (480 Mbit/s), full-speed
(12 Mbit/s) and low-speed (1.5 Mbit/s), and provides a pin-optimized, physical layer
front-end attachment to the USB host, peripheral and OTG devices.
It is ideal for use in portable electronic devices, such as mobile phones, digital still
cameras, digital video cameras, Personal Digital Assistants (PDAs) and digital audio
players. It allows USB Application-Specific Integrated Circuits (ASICs), Programmable
Logic Devices (PLDs) and any system chip set to interface with the physical layer of the
USB through a 12-pin interface.
The ISP1504x1 can interface to devices with digital I/O voltages in the range of 1.65 V to
3.6 V. The ISP1504x1 is available in TFBGA36 package.

UM10079:ISP1504A1; ISP1504C1 ULPI transceiver evaluation board, supporting Hi-Speed USB host, peripheral and OTG


The ISP1504A1; ISP1504C1 (ISP1504x1) is an 8-bit bidirectional UTMI+ Low Pin
Interface (ULPI) transceiver, which provides a Hi-Speed Universal Serial Bus (USB)
analog front-end solution to Application-Specific Integrated Circuits (ASICs) and Field
Programmable Gate Arrays (FPGAs) to implement as a Hi-Speed USB host, peripheral
or OTG device.
The ISP1504x1 evaluation (eval) board allows designers to evaluate the features of the
ISP1504x1, and conduct system-level validation and testing. The eval board interfaces to
the link through a 100-pin Transceiver and Macrocell Tester (T&MT) connector that
complies with USB 2.0 Transceiver and Macrocell Tester (T&MT) Interface Specification
Ver. 1.2.
