ADSP-2181 basic information

Hi!
1)I need to know the type of program memory in DSP i think SRAM but
why sram??
2) Have ADSP-2181 2 A/D and D/A or 1?
3) HAve ADSP-2181 eeprom??
4) have ADSP 2181 real time clock??
5) have 2181  PWM?? 


Thx.

1.  SRAM is faster, and with the process technology they used they 
couldn't get the speed with flash.  The TI TMS320F28xx DSPs use flash 
for program memory and it's about 8 times slower than the internal SRAM.

2, 3, 4, 5.  Go to http://www.analog.com, get a data sheet, take a look.

The data sheet will tell you about all that stuff.
