The FT313H is a USB2.0 compatible EHCI single port host controller which is mainly composed
of the following:
The functions for each block are briefly described in the following subsections.
4.1 Microcontroller Bus Interface
The FT313H has a fast advance general purpose interface to communicate with most types of
microcontrollers and microprocessors. This microcontroller interface is configured using pins
ALE/ADV_N and CLE to accommodate most types of interfaces. The bus interface supports 8-
bit and 16-bit, which can be configured using bit DATA_BUS_WIDTH. Three bus interface types
are selected using inputs ALE/ADV_N and CLE during power up, the RD_N /RE_N/OE_N and
CS_N/CE_N pins, or the RESET_N pin. Table 4.1 provides detail of bus configuration for each
mode. Table 4.2 shows pinout information of each bus interface.
