Hi Experts, I am about to change my controller from Philips 87C591 to DS89C450 for speed, memory and flash. Anybody has experience with this chip and any difficulties in porting to this chip. Thanks in advance, Prem

For any device specific issues look at the errata at http://www.maxim-ic.com/qa/info/errata/ suggests the A2 step has 3 issues, whilst the A4 step is fine.... On a general porting basis, the 450 is, of course, faster -jg
