Re_ [lpc2000] Re_ IAP_Flash Programming Time

2005-04-29 by Ralf Knorr

Ok,
I've just remeasured the following times on an LPC2106:

Erase sector 1-14: 100ms
Program 512 bytes starting from adress 0x2200: 250\ufffds

My xtal is 14.7456MHz and I use PLL with  multiplying factor 4, and Pll 
devider 2. VPBdivder is set to CPU clock /4.

If you want to programm whole flash (0x0-0x1DFFFF) it should take about ~1s.
