Post by thread:16c55x voltage/freq

I'm considering using the 16C554 in an app. that will run on 3 Ni-Cd's (3.6V) with a high (16-20Mhz) clock. In reading the documentation, I have not seen any reference to clock speed in relation to supply voltage. Am I missing something, or can you indeed run a 16C554 up to 20Mhz on 3.6 volts? John

Adding another cell would probably double the life you'd get. -- Friendly Regards Tjaart van der Walt spam_OUTtjaartTakeThisOuTwasp.co.za |--------------------------------------------------| | WASP International | |R&D Engineer : GSM peripheral services development| |--------------------------------------------------| |SMS +.....27832123443KILLspam@spam@sms.co.za (160 chars max)| | http://www.wasp.co.za/~tjaart/index.html | | Voice : +27-(0)11-622-8686 | | Fax : +27-(0)11-622-8973 | | WGS-84 : 26¡10.52'S 28¡06.19'E | |--------------------------------------------------|
