72 MHz Cortex-M0+ with USB and analog muscle
The NXP MKL82Z128VMP7 is a 32-bit ARM Cortex-M0+ MCU from the Kinetis KL8 series, clocked at 72 MHz. It carries 128 KB of Flash and 96 KB of RAM — the RAM allocation is notably deep for an M0+ part, which helps when buffering USB audio or handling multiple sensor data streams without external memory. On the analog side, an 11-channel 16-bit ADC and a 12-bit DAC sit on-chip, alongside a separate 6-bit DAC for lower-resolution auxiliary outputs. The 72 MHz core speed is the practical ceiling for the Cortex-M0+ architecture; at this frequency the part can service a USB OTG link, run a modest RTOS tick, and still leave headroom for peripheral DMA transfers without stalling.
Industrial temperature reach and package
Supply range spans 1.71 to 3.6 V.
NXP lists the MKL82Z128VMP7 as Active. No last-time-buy window has been announced, and the part is still in normal production. For a BOM that needs a Kinetis KL8 MCU with USB and 96 KB RAM, this is a current-generation choice — not an end-of-life cross-ship.
