EZ-Host™ (CY7C67300) is Cypress Semiconductor’s first full-speed, low cost multiport host/peripheral controller. EZ-Host is designed to easily interface to most high performance CPUs to add USB host functionality. EZ-Host has its own 16-bit RISC processor to act as a coprocessor or operate in standalone mode. EZ-Host also has a programmable IO interface block allowing a wide range of interface options.

Features include: 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, 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, supports 12 MHz external crystal or clock, 3.3V operation, automotive AEC grade option (–40°C to 85°C),package option—100-pin TQFP
