ADSP-2181 basic information

Started by June 14, 2006
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. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com Posting from Google?

The data sheet will tell you about all that stuff. Leon
