Hi, I want to replace my current Atmega128L project (running at 8MHz) with a LPC2114 (also to be run at 8MHz). My motive of doing this is that LPC2114 is more powerful and is better prepared for future upgrade. However, my project is battery operated. My concer

Hi all The LPC2114 datasheet explains that the VSSA and VSSA_PLL pins should nominally be the same voltage as VSS, but should be isolated to minimize noise and error, and likewise with V18A and V3A. Any examples of how such filtering is done? Since the LP

Can anyone tell me where to get an updated user manual of lpc2114/01? This new version, according to datasheet, has fractional baud generator in its uart. No address and information given though. If I assume it's similar to lpc2368 and initialize it accordingly, the uart receives many framing errors. Thanks, Kerem

I just read through the users manual for the LPC2114 and from what i can deduce the ETM output can be individually disabled simply by not tying a pull up resisitor to P1.20/TRACESYNC. I.e. you should be able to use the ETM port pins as normal IO pins while debugging through the J

Hi, i am working with a Development Board based on a LPC2114. We have made the port for FreeRTOS using the instructions available in FreeRTOS's web page, modifying the Demo for LPC2106 (because we use GCC compiler) and comparing with the Demo for LPC2129 (because there are only very little differences with this micro). The Demo seemed to worked just fine, but the problem comes when we use th...

Hello, Can anyone double check my understanding please. On LPC2114 you can enable JTAG or ETM or both. When enabeling JTAG only you can use the ETM pins as I/O; therefore, only 6 pins are needed to connect to the chip and debug and all the rest of the pins can be I/O

We have used Keil Uv2 (assemblers & C) and Ceibo emulators & programmers for the 87C554 family of chips for years. The 87C is great but it is becoming an antique.
