Hello embedded people! We have a new project that may require operation at perhaps 105`C. This is well above what I am used to working with, so I have not paid much attention to "extended" temperature range parts. Now I need to find some! I am looking for suggestions for microcontrollers. Would prefer something modern and C (gcc) friendly, like e.g. the LPC2100 series I was going to use...

I want to connect the UART of the micro (LPC2100) to a cell phone serial port. Both devices should probably have short circuit protection but neither use +-15V true RS232 specs. Do I need a line driver chip between or is there a simpler (less cost/parts) way of making the connection? Thanks.

Hello Folks, The Philips ARM series had been out of my price range but the LPC2101 finally seems to be in reach, meaning under $2 in quantity. Now if one wants to try it out which kit would work? I'd have no problem if it was for another one of the ARM chips as they seem to be quite compatible. The only kit for the lower number parts I found at Digikey was the KS2106 LPC210x Kickstar...

I'm looking for the lowest power ARM7 MCU out there... one with the best mips/watt ratio. Its hard to compare the benchmarks used by various manufacturers since they measure active Idd in various ways, but the process technology (130nm, 90nm etc) is almost never specified. I've been looking at the LPC2101 which I believe is built with a 90nm process, but Ive heard there are intel parts that...

Hi everybody, I am looking for an ARM MCU with the following constraints (in the order of importance): - 4 channel ADC with > = 500 k samples/s - Price in 1k units < $1.50 - Frequency "as high as possible" but at least 32 MHz - 1 UART - RAM and Flash negligeable (1k RAM and 4k Flash would be largely enough). I found the LPC2102 from NXP which almost hit the price mark. I also got the im

Hi, Has anyone successfully programmed an LPC2103 using Rowley Associates CrossWorks for ARM and the ARM USB CrossConnect? It does explicitly support LPC2104, but it doesn't say anything about 2103. I know the LPC2103 is newer, but it also has less memory, and I don't know if that makes it impossible to support it. Any experience? Thanks in advance,

Hello. I've a problem with LPC2103. I've two boards. The first-one is a Silica Demo Board with a Philips (with Philips logo) LPC2103.

Hi Gurus, I am switching from AVR to ARM. Currently, I use an ATmega162 which is running out of code space (16kB) and performance. But I find it difficult to choose between Atmel's ARM (looking at the SAM7S series) and thePhilips LPC2104/5/6 series. I don't need many peripherals (yet). My current design uses an FTDI chip for USB, I could save that by using Atmel (Philips has no USB), but o...
