CY7C67300
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 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.
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.
Functional Overview
An overview of the processor core components are presented in
this section.
Power Management
EZ-Host has one main power saving mode, Sleep. Sleep mode
pauses all operations and provides the lowest power state.
Processor Core
EZ-Host has a general purpose 16-bit embedded RISC
processor that runs at 48 MHz.
Interface Descriptions
EZ-Host has a wide variety of interface options for connectivity.
With several interface options available, EZ-Host can act as a
seamless data transport between many different types of
devices.
See
Table 1
and
Table 2 on page 4
to understand how the inter-
faces share pins and which can coexist. Note that some inter-
faces have more then one possible port location selectable
through the GPIO control register [0xC006]. General guidelines
for interfaces are as follows:
■
■
■
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.

USB Interface
EZ-Host has two built in Host/Peripheral SIEs and four USB transceivers that meet the USB 2.0 specification requirements for full and
low speed (high speed is not supported). In Host mode, EZ-Host supports four downstream ports, each support control, interrupt, bulk,
and isochronous transfers. In Peripheral mode, EZ-Host supports one peripheral port with eight endpoints for each of the two SIEs.
Endpoint 0 is dedicated as the control endpoint and only supports control transfers. Endpoints 1 though 7 support interrupt, bulk (up
to 64 bytes/packet), or isochronous transfers (up to 1023 Bytes/packet size). EZ-Host also supports a combination of Host and
Peripheral ports simultaneously as shown in
Table 3.
