General Description
The IP403 is a dual-functional controller chip, the serial-to-parallel LED driver and GPIO controller. The serial-to-parallel LED driver can replace up to 7 74LV164 glue logic chips.
The GPIO controller is similar to the commonly used 8255 I/O controller. Furthermore IP403 provides the programmable input stable timer, allowing the designer to set the input de-bounce time. IP403 also provides the flexibility for the designer to program the interrupt source of individual input change.
When set to LED driver mode, IP403 can directly drive 56 LEDs or 48 LEDs, depending on either single serial input or triple serial input. If set to single serial input mode, all LED driver pins are linked internally with the internal shift registers. If set to triple serial input mode, each serial input corresponds to 16 LED driver pins, meaning that 48 LEDs driver pins in total. In GPIO mode provide 52 GPIO.
Application
• Serial-to-parallel LED Driver
- High port count switch LED driver
- Bi-color or mono-color LED driver
- Static (non-scan method) 7 digit 7-segment LED driver
- LED matrix driver
• General Purpose Input Output(GPIO)
- Factory/Office security system
- Keyboard scanning
