I created a simple SAM7 based cpu box for a customer a while ago. You can view it at http://www.silicontkx.com/PECS.htm. It's interesting because it has a large CPLD connected to the SAM7 and an ethernet chip. It can speak JTAG and I2C externally and is designed to control a number of lines on a switch evaluation board. It might make a re

It's because of several reasons! Some of which are: 1) Ethernet PHY's are mixed-signal devices which - are difficult to build in 0,18um process (which SAM7 is manufactured in) - are difficult to integrate with other (maybe sensitive) circuitry; e.g. internal RC-osc in SAM7 ++ - use quite a lot of power in both transmit&receive (> 30mA typically) - both generate a lot of, an

Hi all, Might sound stupid, but it occured to me before to check if the size/pitch etc. of SAM7S128/256 fits into a QFP64 of a MSP430 P140 FET kit. It does, so one of these days - instead of replacing the S64 on my EK - I thought I'd try wiring on vero with the FET, wired for SAM7. There's a few cuts to make, but minor.

Does this mean that the SAM7 device would stop working? I'm not entierly satisfied with a flash mem with only 10 years retention, TI manages 100 years, the very old HC11 series had 20-30 years guaranteed at 25 deg C. So where does this put ATMEL?

AT91SAM7...nifty chip... but I have to admit to considerable frustration trying to get this thing to do what I want. Basically, I have the AT91SAM7S-EK board attached by ribbon cable to a vectorboard on which I've placed one of TI's TLV320AI23B codecs. The larger goal is to use the SSC controller in the Sam7 to talk to the codec. I intend to sample low freq audio and generate low-freq test

Has anyone taken any power consumption measurements for the SAM7S series at 1 or 2 Mhz? Most of the ARM's I am looking at (NXP, analog devices) have high bias currents (a high minimum, like 5-7mA plus a certain mA/Mhz adjustment for speed). The analog devices SAM7 micros bottoms out at around 10mA at 325Khz, for instance, but at 40Mhz, its around 40mA. I think the NXP's low end are arou...

Hello, First post to the list. I am in the process of redesigning an ATMega128 unit, and am thinking about the sam7s128 or s256. I was also looking at the LPC2106. From first impressions, it seems that the sam7s seems to have more, and better peripherals. Is this the group consensus? I have the Olimex 2106 dev board and wiggler with GNUARM and eclipse. I also have the SAM7-H64 module (
