PRODUCT DESCRIPTION

The SST65P542R is a member of SST’s 8-bit application

specific microcontroller family targeted for IR remote con-

troller applications.

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.

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.

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 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.
