ISP1512A
General description
The ISP1512A is a UTMI+ Low Pin Interface (ULPI) Hi-Speed Universal Serial Bus (USB) transceiver that is fully compliant with Universal Serial Bus Specification Rev. 2.0 and UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
The ISP1512A 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 controller with Single Data Rate (SDR) ULPI link. The ISP1512A can transparently transmit and receive UART signaling.
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) or any system chip set to interface with the physical layer of the USB through a 12-pin SDR interface.
The ISP1512A can interface to devices with digital I/O voltages in the range of 1.65 V to 1.95 V.
The ISP1512A is available in WLCSP25 package.
Features
- Fully complies with:
- USB: Universal Serial Bus Specification Rev. 2.0

- Interfaces to USB host or peripheral cores; optimized for portable devices or system ASICs with built-in ULPI link
- Complete Hi-Speed USB physical front-end solution that supports high-speed
(480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s)
- Integrated 45 Ohm +- 10 pct high-speed termination resistors, 1.5 kOhm +- 5 pct full-speed device pull-up resistor, and 15 kOhm +- 5 pct host termination resistors
- Integrated parallel-to-serial and serial-to-parallel converters to transmit and receive
- USB clock and data recovery to receive USB data up to +-500 ppm
- USB data synchronization from 60 MHz input to 480 MHz output during transmit
- Insertion of stuff bits during transmit and discarding of stuff bits during receive
- Non-Return-to-Zero Inverted (NRZI) encoding and decoding

- Integrated Phase-Locked Loop (PLL) supporting input clock frequency of 19.2 MHz
- Fully programmable ULPI-compliant register set
- 3-pin or 6-pin full-speed or low-speed serial mode
- Internal Power-On Reset (POR) circuit
- UART interface:
- Supports transparent UART signaling on the DP and DM pins for UART accessory applications
- 2.7 V UART signaling on the DP and DM pins
- Entering UART mode by register setting
- Exiting UART mode by asserting STP or by toggling the CHIP_SEL pin
- Full industrial grade operating temperature range from -40 Cel to +85 Cel
- ESD compliance:
