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.
