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
Single chip USB to UART interface.
Entire USB protocol handled on the chip. No
USB specific firmware programming required.
Supports USB bulk transfer mode
Basic UART interface with RXD, TXD, RTS#,
CTS# pins.
TX_ACTIVE signal for controlling transceivers
on RS485 interfaces.
UART RX buffer size is 5512 bytes
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)
12MHz oscillator using external crystal.
Integrated power-on-reset circuit.
+3V3Single Supply Operation with 5V tolerant
USB 2.0 Full Speed compatible.
Extended operating temperature range; -40C
to 85C.
