Improves frequency accuracy over temperature, age, process,
and initial offset.
Nonvolatile programming enables easy customization, fast
turnaround, performance tweaking, design timing margin
testing, inventory control, lower part count, and more secure
product supply. In addition, any part in the family can also be
programmed multiple times, which reduces programming
errors and provides an easy upgrade path for existing designs.
In-house programming of samples and prototype quantities is
available using the CY3672 development kit. Production
quantities are available through Cypress Semiconductor’s
value added distribution partners or by using third party
programmers from BP Microsystems, HiLo Systems, and
others.
Performance suitable for high-end multimedia,
communications, industrial, A/D Converters, and consumer
applications.
Supports numerous low power application schemes and
reduces EMI by enabling unused outputs to be turned off.
Adjusts crystal drive strength for compatibility with virtually all
crystals.3-bit external frequency select options for PLL1, CLKA,
and CLKB.
Industry-standard supply voltage.Industry-standard packaging
saves on board space.Easy to use software support for design
entry.
