'[EE]: Parallax drops prices on all SX chips'

Looks like Parallax dropped the pricing on SX chips in single quantities
quite significantly -- SX-20/28//48 are now US$2.79 in single quantity.

They supposedly have 407,000 SX-28/SS-Gs in stock -- maybe Maxim could learn
from them ;-)

looks like a smart move for them

If you after horsepower they still look expensive compared to Philips LPC range 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 Automatic Bootloader + ISP/IAP)
       External Memory controller (LPC2378)
       10/100 Ethernet with its own dedicated DMA + 16k Independent RAM (Free 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=LPC2368

Standard Cost for the LPC2366 (User Memory 256k Flash / 32k RAM) £3.10 (about ~$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 there.

PIClist is unique because of [OT] and [WOT] ;-) For technical topics
on PIC, Microchip Forum is the best but PIClist is also good.

GNUARM resource page (http://www.gnuarm.com/resources.html)
is a good summary of ARM MCU related resources.

There are many good Yahoo lists on ARM. I do not like the Yahoo
group interfaces though. The best is of course LPC2100 Yahoo group.
http://tech.groups.yahoo.com/group/lpc2000/. It is also archived by
Gmane (gmane.comp.hardware.arm.lpc2100 on
news.gmane.org) along with the Atmel AT91SAM list
(gamne.comp.hardware.arm.at91sam).

The news group comp.sys.arm is also quite good. It is also
accessible from Google groups:
http://groups.google.co.uk/group/comp.sys.arm/topics

Xiaofan

Xiaofan,

Thank you for the links, very helpful.  Do you use the Philips devices?

At home, I have one Olimex LPC-P2148 demo board but not playing with
it so much recently. I am tyring to learn USB stuff and ARM-GCC with
this board.

At work, we are using TI TMS470 MCU. The TI part is not as good
(need 3.3V/1.8V dual LDO and the I/O is not 5V tolerant) but they can
guarantee to work at 105 degree C.

Anyone buying this:

Propeller Proto Board - PRE-ORDER
Looks like a bargain.

Thought about it...but then it'll just be something else cluttering up my
gadget box ;)
