Preliminary specification
Shock absorbing RAM addresser
SAA7346
FEATURES
Absorbs shocks from x, y and z directions
Absorbs rotational shocks
Absorbs multiple shocks per second
Interfaces directly to compact disc decoders SAA7345,
SAA7347 and SAA7370
Multi-speed I

S-bus output
Controls 1 or 4 MBit of external Dynamic Random
Access Memory (DRAM)
Easy serial interface for communication with common
microcontrollers
Software selectable shock detectors
By-pass/power-down mode
Kill interface for DAC deactivation
Can be used for:
– ‘sampling’ part of a disc
– to reduce access pauses between jumps
– to deliver a programmable delay
– to generate a fixed audio rate from Constant Angular
Velocity (CAV) discs.
GENERAL DESCRIPTION
The SAA7346 can be used to make a CD player
insensitive to shocks. To do this, SAA7346 operates
closely with a standard 1 Mbit or 4 Mbit DRAM. Audio data
is stored inside the DRAM and during shocks the data of
the DRAM can be played. The SAA7346 functions as a
customized DRAM controller with serial I/O and on-board
shock detectors.
