I know this chip. He has
- Interrupt in 8bit mode
- 16K SRAM on board
- lower price
However, he has also
- only available in 5V, not 3.3V, so in today systems, an interface is needed
(SystemCosts++)
- nobody knows how long realtek will manufacture the chip. Cirrus Logic
has made a comittment that the CS8900A was especially redesigned to
3.3V for the embedded market and will be available for long time.
- Realtek needs a special filter transformer (SystemCosts++)
- Cirrus has a larger user base and more free sourcecode available.
- Cirrus has more documentation.
So, for me as a system designer, it is VERY difficult to select the
"right" chip.
