SERIAL ACCESS CMOS 8K (1024*8) EEPROM ST24C08
The ST24C08 is a 8Kbit electrically erasable programmable memory (EEPROM), organised as 4 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.

TDA8885:
16.1.1.
GENERAL DESCRIPTION
The TDA 8885 is I
2
C-bus controlled singlechip TV processors, which are intended to be applied in
PAL/NTSC and multi-standard television receivers. These ICs are largely compatible with the TDA
884X/5X series. Also in this IC family we have versions with a mono intercarrier FM sound channel and
versions with a QSS IF amplifier.
The main difference between the TDA 884X/5X series and the TDA 886X/7X/8X series is that the latter
contains integrated sound band-pass (in mono FM versions) and trap circuits, a switchable group delay
correction circuit and a multi-standard colour decoder which needs only one inexpensive (12 MHz) reference
crystal for all standards.
Furthermore various picture improvement features have been included.

FEATURES
•
Multi-standard vision IF circuit with an alignment-free PLL demodulator without external components
•
Internal (switchable) time-constant for the IF-AGC circuit
•
Switchable sound trap and group delay correction circuit for the demodulated CVBS signal
•
Flexible source selection with CVBS switch and a Y (CVBS)/C input so that a comb filter can be
applied
•
Integrated chrominance trap circuit
•
Integrated luminance delay line with adjustable delay time
•
Integrated chroma band-pass filter with switchable centre frequency
