ISP1507A Datasheet, PDF (2/81 Pages) List of Unclassifed Manufacturers – ULPI Hi-Speed USB On-The-Go transceiver

ISP1507A; ISP1507B
ULPI HS USB OTG transceiver
‹ Integrated 5 V charge pump; also supports external charge pump or 5 V V_BUS
switch
‹ Complete control over bus resistors
‹ Data line and V_BUS pulsing session request methods
‹ Integrated V_BUS voltage comparators
‹ Integrated cable (ID) detector
„ Highly optimized ULPI-compliant
‹ 60 MHz, 12-bit interface between the core and the transceiver
‹ Supports 60 MHz output clock configuration
‹ Integrated Phase-Locked Loop (PLL) supporting one crystal or clock frequency:
19.2 MHz (ISP1507A) and 26 MHz (ISP1507B)
‹ Fully programmable ULPI-compliant register set
‹ Internal Power-On Reset (POR) circuit
„ Flexible system integration and very low current consumption, optimized for portable
devices
‹ Power-supply input range is 3.0 V to 3.6 V
‹ Internal voltage regulator supplies 3.3 V and 1.8 V
‹ Charge pump regulator outputs 4.65 V to 5.25 V at a current of up to 50 mA,
tunable using an external capacitor
‹ Supports external V_BUS charge pump or 5 V V_BUS switch:
External V_BUS source is controlled using the PSW_N pin; open-drain PSW_N
allows per-port or ganged power control
Digital FAULT input to monitor the external V_BUS supply status
‹ Pin CHIP_SELECT_N 3-states the ULPI interface, allowing bus reuse for other
applications
‹ Supports wide range interfacing I/O voltage of 1.65 V to 3.6 V; separate I/O voltage
pins minimize crosstalk
‹ Typical operating current of 11 mA to 48 mA, depending on the USB speed and
bus utilization; not including the charge pump
‹ Typical suspend current of 35 μA
„ Full industrial grade operating temperature range from −40 °C to +85 °C
„ 4 kV ElectroStatic Discharge (ESD) protection at pins DP, DM, ID, V_BUS and GND
„ Available in a small HVQFN32 (5 mm × 5 mm) Restriction of Hazardous Substances
(RoHS) compliant, halogen-free and lead-free package
