TDA9950

CEC/I²C-bus translator

Rev. 02 — 22 October 2009

Product data sheet

1. 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.

2. Features

2.1 Principal features

I Receive and transmit CEC messages with compliant Signal Free Time handling

I I²C-bus interface to host supporting 100 kbit/s and 400 kbit/s communication

I Supports multiple CEC logical addresses

I Supports CEC messages up to 16 bytes in length

I Programmable retry count

I Comprehensive arbitration and collision handling

I 3.0 V to 3.6 V V_DDoperating range

I Automatic Idle mode to reduce power consumption when there is no message on CEC

line and I²C-bus

I I/O pins are 5 V tolerant

2.2 Additional features

I Processor with embedded software to control the interface between CEC line and

I²C-bus

I 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.

I On-chip oscillator for 12 MHz crystal

I Schmitt trigger port inputs
