9. SERIAL ACCESS CMOS 16K (2048*8) EEPROM ST24C16
The ST24C16 is a 16Kbit electrically erasable programmable memory (EEPROM), organised as 8 blocks
of 256*8 bits. The memory is compatible with the I²C standard, two wire serial interface, which uses a bi-
directional data bus and serial clock. The memory carries a built-in 4 bit, unique device identification code
(1010) corresponding to the I²C bus definition. This is used together with 1 chip enable input (E) so that up
to 2*8K devices may be attached to the I²C bus and selected individually.
10. CLASS AB STEREO HEADPHONE DRIVER TDA1308
The TDA1308 is an integrated class AB stereo headphone driver contained in a DIP8 plastic package. The
device is fabricated in a 1 mm CMOS process and has been primarily developed for portable digital audio
applications.
