Hello, I use a LPC2138 microcontroller with a 25MHz xtal. I set the pll multiplier at 2 and de devider =2 (in the startup code of KEIL). This gives 50MHZ CPU clock. This works out fine, in determining the speed for the UART (baud rate is ok). But when I run a very small program, toggeling the LED's, I only get 16 MIPS out of the controller. The

Hi all, We have been trying to use the SSP controller on the LPC2148 (master) and LPC2138 (slave) as SPI. The hardware design is such that LPC2148 and LPC2138 are connected over the SSP interface.

I'm working on a design with an LPC2148. However, the LPC2148 has a long lead-time in the US. So I'm going to use a LPC2138 until the LPC2148 is ready. The obvious difference is the loss of the USB interface. The rest of the device appears to be electrically and software wise the same. (The LPC2138 does have two 10-bit DACs instead of one on the LPC2148). Any other problems or issues ...
