Great new line of Cortex-M0+ microcontrollers, I can't wait to get mine!!

http://www.nxp.com/news/press-releases/2012/11/nxp-revolutionizes-simplicity-with-lpc800.html

Does anyone knows why NXP doesn't offer 16 and 20 DIP packages in any of its microcontrollers families? There is LPC1114 in 28 DIP package, but it would be nice to have 16 and 20 DIP packages.

With 2 USARTs, it's perfect to make a protocol converter.
For instance, I use a weighing scale which sends unconditionally bursts of strings with weight information and I must interface it with a modbus RTU network.
What I need more than the chip ?:D

analogue periphery seems not to be one of NXP's strength, at least compared to other Cortex M0/M3 vendors...

Cool product. Innovative peripherals..:). But wait. where is my ADC...:eek:
Atleast a four channel 10-bit ADC is needed to kill those 8-bitters. Thanks...;)

Apart from PIC-bashing, I believe analogue blocks consume some more silicon, often require some
factory-trimming on the die, and pull in other blocks (like Vdd decoupling, band-gap voltage references, etc.).

And, to be honest, analogue periphery seems not to be one of NXP's strength, at least compared
to other Cortex M0/M3 vendors...

And what I miss most on Cortex M0 devices is a DIV/IDIV instruction.

Make it 4 ... :p

This does look like a very nice chip, now I have to think of an application for one.

And in case anyone missed our earlier announcement with regards to LPC800 and LPCXpresso...

Beta support for LPC800 Cortex-M0+ parts

Awesome. 32bit cpu in a 8pin package.
Just need some eeprom and ADC and then itll kill everything. ;)

Some weak points:
- only 4 timer outputs

---

There is only one timer, and historically each timer in any NXP uC only has only four outputs

---

Quote:

- lack of ADC

---

I do agree, but there must be a reason why there isn't an ADC in this new family

Quote:

- no low-power UART (but some form of wakeup is probably implemented)

[I]15.3.2 Configure the USART for wake-up
The USART can wake up the system from sleep mode in asynchronous or synchronous mode on any enabled USART interrupt. [/I]

- no 6-pin SOT23-6 version :) - I want one!

You just said you want more than four timer outputs, didn't you? You'll run out of pins!! :D

This uC will rock!!

8-pin one is clearly an ATtiny killer.

And I hope it kills the ineffable PIC1X devices, too.

Strong points:
- 2 UARTs in 8-pin case and < 16 KiB chips, 3 UARTs in bigger models
- switch matrix - assign any pin to any peripheral function
- Flash with 64-byte erasable pages, may be easily used for data
- timer with advanced state machine
- capability to implement any logic function on 8 pins in hardware - may be used also for synthesizing strange logic gates
- wakeup timer for easy waking up from power-saving modes
- new UART without all bad features of historic 16C550

Some weak points:
- only 4 timer outputs
- lack of ADC
- no low-power UART (but some form of wakeup is probably implemented)
- no 8-pin SO-8 or SOT23-8 version
- no 6-pin SOT23-6 version :) - I want one!

Anyway, LPC800 looks like an attractive descendant of LPC111x, esp. considering the 3 UARTs

Well done, NXP. Can't waith to get my hands on the new LPCxpresso board and the chips.

8-pin one is clearly an ATtiny killer.
