Infrared Remote Tx/Rx Reference Designs

Simplify the addition of remote control capability – Lattice Infrared (IR) reference designs simplify and speed the addition of remote control capabilities to mobile devices and consumer electronics products.

In-built hardware interfacing – The reference designs perform all the necessary hardware interfacing for IR receive and/or IR transmit. This includes PWM (pulse width modulation) timing and protocol conversion to an SPI /I2C bus for connection with an applications processor.

Customizable to meet application needs – Each reference design can be used as is or can be customized to meet specific application requirements. Current reference designs incorporate Sony IR codes, Philips IR codes and a self-learning IR remote reference design.
