TDA8261TW

PROGRAMMING

Programming of the TDA8261TW is performed via the

I2C-bus. The read or write selection is made with bit R/W

(address LSB). The TDA8261TW fulfils the I2C-bus fast

mode, according to the Philips I2C-bus specification.

I2C-bus voltage

The I2C-bus lines SCL and SDA can be connected to an

I2C-bus system tied to either 2.5, 3.3 or 5.0 V, that will

allow direct connection to most of the existing

microcontrollers. The choice of the threshold voltage for

the I2C-bus lines is made with pin BVS that needs to be

connected to the supply voltage, to ground or needs an

open-circuit; see Table 1.

Table 1

I2C-bus voltage selection

I2C-bus write mode

I2C-bus write mode: bit R/W = 0; see Table 2.

After the transmission of the address (first byte), four data

bytes can be sent to fully program the TDA8261TW. The

bus transceiver has an auto-increment facility that permits

to program the TDA8261TW with a single transmission:

one address byte followed by four data bytes (PD1, PD2,

CD1 and CD2).

The TDA8261TW can be partly programmed provided that

the first data byte following the address is PD1 or CD1.

The first bit of the first data byte transmitted indicates

whether PD1 (first bit = 0) or CD1 (first bit = 1) will follow.

Until an I2C-bus STOP condition is sent by the controller,

additional data bytes can be entered without the need to

re-address the device. Each byte is loaded after the

corresponding 8th clock pulse. Programmable divider data

(contents of PD1 and PD2) becomes valid only after the

8th clock pulse of PD2, or after a STOP condition if only

PD1 needs to be programmed.
