PT6991 Overview
Description
The PT6991 is designed to integrate the LED driver, key-scan matrix, infrared (IR) remote control decoding and into one integrated solution. All functions are programmable using I2C interface.
Key Features
- IC front panel LED controller driver
- Standby power management to the host
- 5.0V (VDD) supply and 3.3V interface for the IC
- IR remote control decoder (Philips, NEC, Thomson, Sony, Matsushita)
- Multiple display modes ( 10 segments and 6 digits to 12 segments and 4 digits )
- External resistors necessary for all logic outputs (N-CH. Open drain)
- Key scanning (up to 10 x 1 matrix = 10 keys)
- I2C serial interface (SCL, SDA) communication protocol
- Programmable hotkeys for IR remote control command
- Programmable hotkeys for KEYSCAN command
