PRODUCT DESCRIPTION
The SST65P542R is a member of SST’s 8-bit application
specific microcontroller family targeted for IR remote con-
troller applications.
The SoftPartition architecture allows seamless flash mem-
ory partitioning of the program code, protocol tables, and
user data in the small granularity of 128 Byte sectors. The
small sector size and fast Write capability of the device
greatly decreases the time and power when altering the
contents of the flash memory.
The SST65P542R microcontroller provides high functional-
ity to infrared remote controller products. The device offers
flexibility to store different remote control configurations for
controlling multiple appliances. The configurations are
either programmed at the factory during the manufacturing
process or downloaded through firmware.
The highly reliable, patented SuperFlash technology
provides significant advantage over conventional flash
memory technology. These advantages translate into
significant cost saving and reliability benefits for the
customers.
Using SST’s SuperFlash nonvolatile memory technology,
the SST65P542R enhances the functionality and reduces
the cost of conventional universal remote controller devices
by integrating multiple functions of a remote controller sys-
tem in a single chip solution. The built-in LED I/O ports can
directly drive LED indicators. The IR transmitter port drives
signals to the infrared transmitter, which, in turn, remotely
controls the appliances.
