'[EE] An ARM chip that can satisfy me'

What I really like about the PIC is that I can literally take a chip,
stick it into a breadboard, attach it to a PICKIT2 and program it in a
few seconds. From start to finish (blinking an LED) in a few minutes.
Literally. I also like the price range (under $10), the fact that they
can be obtained in DIP packages, require few external components, easy
to program and use, and have enough flash, RAM, and peripherals.

Can anyone recommend an ARM chip that can do all that? More specifically:
* Very easy to prototype with
* Easy to program
* Requires few support components
* Low price
* DIP package
* A good amount of flash and RAM - above 32 K flash and 8 K RA

Forget about the DIP package. the world has moved on.

I'd suggest  the NXP LPC1313

DIP module available - uk.farnell.com/nxp/om11048/kit-dev-lpcxpresso-lpc1343/dp/1777673
2 wire debug interface
On-chip 1% oscillator
32K flash, 8K RAM
Good selection of peripherals, including FIFOs on SPI and UART, PWM on timers etc.
Free commercial quality compiler/debug environment (IAR EWARM Kickstart version, code-limit 32K)

Only minor downside is no on-chip EEPROM, though you can use the self-programming flash for
infrequently chnaged stuff.

Define Easy.

All yes.

> * DIP package
None, forget about DIP for ARM.

> * A good amount of flash and RAM - above 32 K flash and 8 K RAM

No problem with ARM.

There are lots of ARM with embedded FLASH and RAM now, some under USD3.00.

Because you are used to PICs already, you could try a PIC32 device, they
are good also, although they use MIPS architecture. I'm using the
PIC32MX575F256H-80I/PT.
USD8.68 @ units, USD6.82 @ 10 units. 80MIPS, 64K RAM 256K FLASH, 6
USART, 2 SPI and much more. There are smaller devices also.

The greatest advantage for PIC users is that their peripherals are 90%
(or more) compatible with the peripherals on the other PIC families.
