FUNCTIONAL DESCRIPTION

Table 1

Note

1. S = START condition; A2 to A0 = programmable address bits; A = Acknowledge; I3 to I0 = Instruction bits;

SD to SA = subaddress bits; X = don’t care; D5 to D0 = data bits; P = STOP condition.

Valid addresses are:

TDA8444 and TDA8444AT: 40H, 42H, 44H, 46H, 48H, 4AH, 4CH and 4EH

TDA8444T: 48H, 4AH, 4CH and 4EH (A2 is always logic 1).

All other addresses cannot be acknowledged by the circuit. The actual slave address depends on the programmable

Valid instructions are: 00H to 0FH; F0H to FFH.
