DS FT312D USB ANDROID HOST IC Datasheet Version 1.2 Document No.: FT 000816 Clearance No.: FTDI 331 Future Technology Devices International Ltd. DS FT312D (USB Android Host IC) The FT312D is a USB 2.0 Full Speed host IC specifically targeted at providing access to peripheral hardware from an Android platform with a USB device port. The device will bridge the USB port to a UART interface via the Android Open Accessory protocol and has the following advanced features: Single chip USB to UART interface. 12MHz oscillator using external crystal. Entire USB protocol handled on the chip. No Integrated power-on-reset circuit. USB specific firmware programming required. +3V3Single Supply Operation with 5V tolerant Supports USB bulk transfer mode inputs. Basic UART interface with RXD, TXD, RTS , USB 2.0 Full Speed compatible. CTS pins. Extended operating temperature range -40 C TX ACTIVE signal for controlling transceivers to 85 C. on RS485 interfaces. Available in compact Pb-free 32 Pin LQFP and UART RX buffer size is 5512 bytes QFN packages (both RoHS compliant). UART TX buffer size is 256 bytes USB ERROR indicator pin Suitable for use on any Android platform supporting Android Open Accessory Mode (Typically 3.1 onwards, however some platforms may port Open Accessory Mode to version 2.3.4) Neither the whole nor any part of the information contained in, or the product described in this manual, may be adapted or reproduced in any material or electronic form without the prior written consent of the copyright holder.
