Some of the ST's supports IEEE-1588 http://www.embeddedstar.com/weblog/2011/09/21/stm32-f4-mcu/ www.mouser.com/pdfdocs/BRSTM32F4_v7final.pdf I'd suggest a $20 STM32-F4-Discovery (Digikey etc) http://parts.digikey.com/1/parts/2484058-eval-kit-stm32f-discovery- stm32f4discovery.html And a Phy (The mac is in the F4) $10 http://www.ebay.de/itm/DP83848-Ethernet-Physical-Transceiver-RJ45- connector-control-interface-Board-Kit-/260868624339 Some www-sw is here (German use google translate) http://www.mikrocontroller.net/topic/237223#2491080 The F4 even supports "Single precision" Floats in HW , and has both ADC & DAC (with the ADC/DAC vref pin on external pin). 1G flash , 192k Ram , and it runs 168Mhz. I think there is 2 x 32bit timers (Fclock/2) , and a fair amount of 16bit timers. It comes with build in debugger (proprietarary) , but the debug protocol has been reversed ... (see texane project) , and afaik it is now suported in openocd. So arm-gcc & arm-gdb can be used (ie codesourcery). ST suggests Atollic as "gcc" toolchain , but that's imho "handicapped" in the free version. I have earlier suggested the F4-Discovery , as a "Tnut" GPSDO/OCXO/RBXO controller board.
