General description
The TDA9950 is a single-chip CEC/I2C-bus translator with a processor, dedicated to the control and interfacing of the Consumer Electronics Control (CEC), a feature of the High-Definition Multimedia Interface (HDMI).
The TDA9950 is an interface between the CEC protocol and timings and the standard I2C-bus. A message received on the I2C-bus interface is written in a buffer and sent on the CEC line. A message received from the CEC line is stored in a buffer, and an interrupt is generated indicating that a message can be read via the I2C-bus. To reduce its power consumption the TDA9950 sets itself to Idle mode when there is no message on the CEC line nor on the I2C-bus.
Features
Principal features
- Receive and transmit CEC messages with compliant Signal Free Time handling
- I2C-bus interface to host supporting 100 kbit/s and 400 kbit/s communication
- Supports multiple CEC logical addresses
- Supports CEC messages up to 16 bytes in length
- Programmable retry count
- Comprehensive arbitration and collision handling
- 3.0 V to 3.6 V VDD operating range
- Automatic Idle mode to reduce power consumption when there is no message on CEC line and I2C-bus
- I/O pins are 5 V tolerant
Additional features
- Processor with embedded software to control the interface between CEC line and I2C-bus
- Active-LOW reset input and on-chip power-on reset allows operation without external reset components. A reset counter and reset glitch suppression circuitry prevent spurious and incomplete resets.
- On-chip oscillator for 12 MHz crystal
- Schmitt trigger port inputs
