11 / 112 page CY7C67300 Document Number: 38-08015 Rev. *L Page 11 of 112 IDE Features ■ Programmable IO mode 0–4 ■ Block mode transfers ■ Direct memory access to/from internal memory through the IDE data register IDE Pins Charge Pump Interface VBUS for the USB OTG port can be produced by EZ-Host using its built in charge pump and some external components. Ensure the circuit connections look similar to the following diagram. Component details: ■ D1 and D2: Schottky diodes with a current rating greater than 60 mA ■ C1: Ceramic capacitor with a capacitance of 0.1 µF ■ C2: Make capacitor value no more that 6.5 µF since that is the maximum capacitance allowed by the USB OTG specifications for a dual role device. The minimum value of C2 is 1 µF. There are no restrictions on the type of capacitor for C2. If the VBUS charge pump circuit is not to be used, CSWITCHA, CSWITCHB, and OTGVBUS can be left unconnected. Charge Pump Features ■ Meets OTG Supplement Requirements, see Table 134 on page 85 for details. Charge Pump Pins Table 14.
