Hi All, Now, when my Linux C2 programmer (http://www.ise.pw.edu.pl/~wzab/cygnal) works fine, it would be nice to add debugging support. However Silabs (formerly Cygnal) does not provide any information regarding C2 debugging protocol...

Im a real begineer to microcontrollers and i have a project that I want to get off the ground. The project is basically to design a USB based ADC card. I have been looking around, and I have found a uC on the market from Cygnal (now Silicon Labs) that has a 17ch 10bit ADC and a USB controller in one package. The question I have is this: Is a Cygnal 8051 based chip (i have been looking a...


Is Cygnal JTAG/C2 Interface EMI Vulnerable

Hi I'm using a 80C51F302 Cygnal device and I have based the design on what I've read on the Cygnal site that C2 is the way to go for such a pin-limited device. Well in the forum on the site some have commented that the JTAG interface is vulnerable to noise and 4k7 pull-up/down are recommended. But using a low-power device and putting load resistors on the signals seems futile to me. If...

Greetings: Of course we haven't seen them yet, but when 25MHz MSP430s come along, with their fast 12-bit A/D and D/A capabilities, combined with the Cygnal 100MIPS 8051 derivatives with fast 12-bit A/D and D/A as well, the AVR with its 16MIPS and only 10-bit A/D slow 15ksps with no dedicated D/A hardware, is looking a bit on the meager side. Is Atmel going to try to compete with thes...

Hi all, Is there a good alternative for the cygnal processors? - In System Programmable - In Application Programmable - Small packages (footprints) available (like the MLP11) - Not to expansive development tools - Wide range family - Cheap (cheaper then the silabs) - Reliable (not the same flash problems as the Silabs) - It don't have to be 8051 cores.
