F81535 is the ideal bridge between USB to Octa (8) UART controller and which is complies with USB 2.0 as well as the standard serial port specification. Each UART includes 128-byte send/receive FIFO, a baud rate generator, complete modem control capability an interrupt system.
The F81535 will enter suspend mode when suspend signaling is detected on the bus. Upon entering suspend mode, the F81535 asserts the SUSPEND and SUSPEND# signals. The SUSPEND and SUSPEND# signals are also asserted after the F81535 reset until device configuration during USB enumeration is complete. The F81535 exits the suspend mode when any of the following occur: resume signaling is detected or generated, a USB Reset signal is detected, or a device reset occurs. On exit of suspend mode, the SUSPEND and SUSPEND# signals are de-asserted.
The device built in +1.8V & +3.3V LDO regulators.
