Introduction
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-perfor-
mance 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 I/O
interface block allowing a wide range of interface options.
Functional Overview
An overview of the processor core components are presented
in this section.
Processor Core
EZ-Host has a general-purpose 16-bit embedded RISC
processor that runs at 48 MHz.
Clocking
EZ-Host requires a 12-MHz source for clocking. Either an
external crystal or TTL level oscillator may be used. EZ-Host
has an internal PLL that produces a 48-MHz internal clock
from the 12-MHz source.
Memory
EZ-Host has a built-in 4K × 16 masked ROM and an 8K × 16
internal RAM. The masked ROM contains the EZ-Host BIOS.
The internal RAM can be used for program code or data.

Interrupts
EZ-Host provides 128 interrupt vectors. The first 48 vectors
are hardware interrupts and the following 80 vectors are
software interrupts.
General Timers and Watchdog Timer
EZ-Host has two built-in programmable timers and a
Watchdog timer. All three timers can generate an interrupt to
the EZ-Host.
Power Management
EZ-Host has one main power saving mode, Sleep. Sleep
mode pauses all operations and provides the lowest power
state.
Interface Descriptions
EZ-Host has a wide variety of interface options for connec-
tivity. With several interface options available, EZ-Host can act
as a seamless data transport between many different types of
devices.

share pins and which can coexist. It should be noted that some
interfaces have more then one possible port location
selectable through the GPIO Control Register [0xC006].
Below are some general guidelines:
• HPI and IDE interfaces are mutually exclusive.
• If 16-bit external memory is required, then HSS and SPI
• I
default locations must be used.
