The SST65P542R is a member of SST's 8-bit application specific microcontroller family targeted for IR remote controller applications.

The SST65P542R microcontroller provides high functionality 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.

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 system 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.

The SoftPartition architecture allows seamless flash memory 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 SST65P542R greatly decreases the time and power when altering the contents of the flash memory.

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.
