If you after horsepower they still look expensive compared to Philips LPC r=
ange of ARM micros.  I'm just looking to move from PIC/AVR to these as they=
 offer an incredible amount of perhipherals and performance for the cost of=
 a 18F PIC e.g. quoting from an email a disty recently sent:

        Memories - 128k -> 512k Flash (128b wide) / 16k -> 58k RAM (Full Au=
tomatic Bootloader + ISP/IAP) =

        External Memory controller (LPC2378) =

        10/100 Ethernet with its own dedicated DMA + 16k Independent RAM (F=
ree Stack online) =

        USB 2.0+ PHY Again with its own DMA + 4k RAM (Free HID online) =

        Many improved Sleep and Power Down Modes =

        1x GP DMA =

        3x SPI (2xSSP 1xSPI) =

        4x 32Bit Independent Timers (Capture/Compare) =

        1x RTC with 2k battery RAM =

        2x PWM (both able for double edge allowing full motor control) =

        4x UARTs (all 16C550 + one enhanced for modem control) =

        SD and MMC Interface =

        3x I2C (Full Speed 400kHz) =

        1x I2S =

        1x 10bit ADC =

        1x 10Bit DAC =

        And on......PLL, Osc, VIC, JTAG-ICE, ETM, POR, BOD..... =

        70x I/O (all 5V tolerant) =

        Packages - Single family package LQFP100 - Allows you to move up or=
 down the memory keeping the same PCB layout.

DS/UM/SW: http://www.standardics.nxp.com/support/documents/microcontrollers=
/all/?scope=3DLPC2368 =


Standard Cost for the LPC2366 (User Memory 256k Flash / 32k RAM) =A33.10 (a=
bout ~$6)

The lower memory/feature parts start from $1.47 in quantity.

Is there anything like the Piclist for the ARM?  I know...nothing will EVER=
 be like the Piclist, but am hoping there are some decent resources out the=
re.
