There are more chips in NXP’s LPC8xx ARM µC family. We’ve seen the delightful 8-DIP LPC810, which packs a lot of power and is an interesting way to get started with ARM, and we’ve seen the LPC812 which is available in a tiny TSSOP-16 package, yet has 4 times the flash and RAM memory of the LPC810.
But there’s one more interesting member in this family: the LPC824, which can easily compare (and exceed) the specification of that workhorse of the Arduino world, the venerable ATmega328. This week’s episode is about getting familiar with the LPC824:
The LPC824 could make a really nice foundation for remote sensor nodes: loads of modern hardware peripherals, ultra-low sleep mode power consumption, and plenty of I/O pins.
I’m really excited about this chip. As with all the LPC8xx chips, there’s a “switch matrix” to connect (nearly) any h/w function to any pin. This means that you don’t really have to care much about pinouts and figuring out up front which pins to use for which tasks. This offers a lot of flexibility when designing general-purpose boards with a bunch of headers on them.
