Feature 1: IrSimple-4M utilized for high-speed communication
|
High speed data transmission is achieved using IrSimple, a high-speed infrared communication protocol 50 times faster than IrDA SIR (115.2Kbps) and 4-10 faster than IrDA FIR (4Mbps). High quality images can be transmitted almost instantaneously. |
 |
Feature 2: Easy to add onto existing systems
 |
|
 |
|
| ROHM’s IrDA controller ICs feature a general-purpose CPU interface that allows virtually any CPU to be used, making it possible to add IrDA communication functionality to sets without worrying about the CPU compatibility.. |
| |
Feature 3: Built-in 5kbyte FIFO and 16bit data bus width lightens CPU load
|
The internal 5kbyte high capacity FIFO stores 2 frames worth of data, reducing the number of CPU interrupts. This, combined with a 16bit data bus width, significantly lightens the load on the CPU. |
