TH6503

USB Low-Speed Interface

Description

The TH6503 is an integrated circuit which enables

the Universal Serial Bus (USB) to be connected to

a microcontroller. The interface module contains

all the components required to transmit data via

the USB.

The TH6503 has been developed for applications

requiring a low speed interface to the USB. Any

microcontroller can be used for control purposes.

In addition to the default endpoint 0 for control

transfer up to two endpoints can be supported by

TH6503. The TH6503 has been developed in

conformity with USB Specifications 1.1.

Figure 1. Typical TH6503 Sample Application

Figure 1 demonstrates a typical TH6503 applica-

tion. The TH6503 translates the data and control

signals received from the USB in a serial format

which can be read by the microcontroller. The data

is stored in a FIFO buffer and can be called up from

a standard microcontroller via a register program-

mable serial interface at any time and processed

further. Data generated by peripheries is passed

to the TH6503 with the same protocol and stored

in a FIFO buffer until it is collected by the USB. The

TH6503 translates all the data in the USB-specific

format and generates the necessary control sig-

nals. The TH6503 requires a minimum number of

external elements and can easily be implemented

in a circuitry. It provides an external clock which

can be used to activate a microcontroller.
