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.

9.8 CSP Package Bootloader

A factory-installed bootloader program is included in all devices

with CSP packages. The bootloader is compatible with PSoC

Creator 3.0 bootloadable project files, and has the following

features:



I2C-based



SCLK and SDAT available at P1[6] and P1[7], respectively



External pull-up resistors required



I2C slave, address 4, data rate = 100 kbps



Single application



Wait 2 seconds for bootload command



Other bootloader options are as set by the PSoC Creator 3.0

Bootloader Component default



Occupies the bottom 9 Kbytes of flash

For more information on this bootloader, see the following

Cypress application notes:



AN73854, PSoC 3 and PSoC 5 LP Introduction to Bootloaders



AN60317, PSoC 3 and PSoC 5 LP I2C Bootloader

Note that a PSoC Creator bootloadable project must be

associated with .hex and .elf files for a bootloader project that is

configured for the target device. Bootloader .hex and .elf files

can be found at www.cypress.com/go/PSoC5LPdatasheet.

The factory-installed bootloader can be overwritten using JTAG

or SWD programming.

10. Development Support

The CY8C52LP family has a rich set of documentation,

development tools, and online resources to assist you during

your development process. Visit

psoc.cypress.com/getting-started to find out more.

10.1 Documentation

A suite of documentation, to ensure that you can find answers to

your questions quickly, supports the CY8C52LP 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 Datasheets

: The flexibility of PSoC allows the

creation of new peripherals (components) long after the device

has gone into production. Component datasheets 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.

Note

Visit www.arm.com for detailed documentation about the

Cortex-M3 CPU.

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 CY8C52LP family is part of a development tool

ecosystem. Visit us at www.cypress.com/go/psoccreator for the

latest information on the revolutionary, easy to use PSoC Creator

IDE, supported third party compilers, programmers, debuggers,

and development kits.
