Post by thread:[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

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.

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.
