• Manufacturer Part Number: CY8C5487LTI-007
• Manufacturer: Cypress Semiconductor Corp

Specifications of CY8C5487LTI-007

• Lead Free Status / RoHS Status: Compliant

The user can write the key into the WOL to lock out external
access only if no flash protection is set (see
section on page 15). However, after setting the values in the
WOL, a user still has access to the part until it is reset. Therefore,
a user can write the key into the WOL, program the flash
protection data, and then reset the part to lock it.
If the device is protected with a WOL setting, Cypress cannot
perform failure analysis and, therefore, cannot accept RMAs
from customers. The WOL can be read out via Serial Wire Debug
(SWD) port to electrically identify protected parts. The user can
write the key in WOL to lock out external access only if no flash
protection is set. For more information on how to take full
advantage of the security features in PSoC see the PSoC 5
TRM.
Disclaimer
Note the following details of the flash code protection features on
Cypress devices.
Cypress products meet the specifications contained in their
particular Cypress data sheets. Cypress believes that its family
of products is one of the most secure families of its kind on the
market today, regardless of how they are used. There may be
methods, unknown to Cypress, that can breach the code
protection features. Any of these methods, to our knowledge,
would be dishonest and possibly illegal. Neither Cypress nor any
other semiconductor manufacturer can guarantee the security of
their code. Code protection does not mean that we are guaran-
teeing the product as “unbreakable.”
Cypress is willing to work with the customer who is concerned
about the integrity of their code. Code protection is constantly
evolving. We at Cypress are committed to continuously
improving the code protection features of our products.

10. Development Support
The CY8C54 family has a rich set of documentation, devel-
opment tools, and online resources to assist you during your
development process. Visit
find out more.
10.1 Documentation
A suite of documentation, to ensure that you can find answers to
your questions quickly, supports the CY8C54 family. This section
contains a list of some of the key documents.
Software User Guide : A step-by-step guide for using PSoC
Creator. The software user guide shows you how the PSoC
Creator build process works in detail, how to use source control
with PSoC Creator, and much more.
Component Data Sheets : The flexibility of PSoC allows the
creation of new peripherals (components) long after the device
has gone into production. Component data sheets provide all of
the information needed to select and use a particular component,
including a functional description, API documentation, example
code, and AC/DC specifications.
Application Notes : PSoC application notes discuss a particular
application of PSoC in depth; examples include brushless DC
motor control and on-chip filtering. Application notes often
include example projects in addition to the application note
document.
Technical Reference Manual : PSoC Creator makes designing
with PSoC as easy as dragging a peripheral onto a schematic,
but, when low level details of the PSoC device are required, use
the technical reference manual (TRM) as your guide.

10.2 Online
In addition to print documentation, the Cypress PSoC forums
connect you with fellow PSoC users and experts in PSoC from
around the world, 24 hours a day, 7 days a week.
10.3 Tools
With industry standard cores, programming, and debugging
interfaces, the CY8C54 family is part of a development tool
ecosystem. Visit us at
latest information on the revolutionary, easy to use CyDesign
IDE, supported third party compilers, programmers, debuggers,
and development kits.
