This document details the features of the ISP1507, which is a USB OTG transceiver produced by ST-NXP Wireless.
The ISP1507A and ISP1507B are ULPI‑compliant USB On‑The‑Go transceivers that support high‑speed (480 Mbit/s), full‑speed (12 Mbit/s) and low‑speed (1.5 Mbit/s) operation. They are designed for portable devices such as mobile phones, digital cameras, PDAs and audio players, providing a 12‑pin interface to the USB link.
The device is offered in an HVQFN32 package and includes integrated charge‑pump regulators, voltage comparators, ESD protection, and programmable registers. It operates over a wide input voltage range (3.0 V‑3.6 V) and temperature range (‑40 °C to +85 °C).
