CY7C67300

EZ-Host™ Programmable Embedded USB Host and

Peripheral Controller with Automotive AEC Grade Support

EZ-Host Features

Single chip programmable USB dual-role (Host/Peripheral) controller with two configurable Serial Interface Engines (SIEs) and four USB ports

Support for USB On-The-Go (OTG) protocol

On-chip 48 MHz 16-bit processor with dynamically switchable clock speed

Configurable IO block supporting a variety of IO options or up to 32 bits of General Purpose IO (GPIO)

4K x 16 internal masked ROM containing built in BIOS that supports a communication ready state with access to I2C™ EEPROM Interface, external ROM, UART, or USB

8K x 16 internal RAM for code and data buffering

Extended memory interface port for external SRAM and ROM

16-bit parallel Host Port Interface (HPI) with a DMA/mailbox data path for an external processor to directly access all of the on-chip memory and control on-chip SIEs

Fast serial port supports from 9600 baud to 2.0M baud

SPI support in both master and slave

On-chip 16-bit DMA/mailbox data path interface

Supports 12 MHz external crystal or clock

3.3V operation

Automotive AEC grade option (–40°C to 85°C)

Package option—100-pin TQFP

Typical Applications

EZ-Host is a very powerful and flexible dual role USB controller that supports a wide variety of applications. It is primarily intended to enable host capability in applications such as:

Set top boxes

Printers

KVM switches

Kiosks

Automotive applications

Wireless access points
