Toto nové MCU, pinovo kompatibilné s nadupanejšou radou LPC5410x/LPC5411x (ARM Cortex-M4/M0+), dostalo do vienka nielen slušnú pamäť (96 KB SRAM/256 KB Flash), ale aj USB, I2S, SCTimer a 12-bitový 5 Msps AD prevodník, pričom jeho cena sa pohybuje okolo 3.20 Eur.
Čím je tento mikrokontrolér zaujímavý?
V NXP konečne začali harmonizovať pinout mikrokontrolérov*. Táto M0 dostala vylepšené periférie, ktoré boli už použité aj u LPC5410x/LPC5411x. Napríklad UART schopný komunikovať až 6.25 Mbps v asynchrónnom režime a 20 Mbps v synchrónnom (staršie verzie periférie šli iba do 4.5/15 Mbps), ADC schopné ísť až do 5.0 Msps (oproti 2 Msps), I2C zvládajúce až 3.4 Mbps (staršie verzie iba do 1 Mbps), SPI zvládajúce až 71 Mbps oproti 17 Mbps....
Bohužiaľ, ani v tomto mikrokontroléri (ani u LPC5410x/LPC5411x) nenájdeme Switch Matrix - funkcia, umožňujúca prepojiť IO periférie na (skoro) ľubovolný I/O pin púzdra.
Tak isto absentujú analógové komparátory a DA prevodník.
... všetky periférie sú ako cez kopirák s LPC5410x/LPC5411x.
