Connectivity includes I²C, SPI, UART/USART, and FlexIO for custom serial protocols, plus a USB 2.0 FS OTG controller. The DMA engine offloads data movement from the core — useful for streaming ADC readings to RAM without CPU intervention.
Yes, the MKL27Z64VFM4 is pin-compatible and shares the same 32-QFN footprint and peripheral set, offering 64 KB Flash instead of 32 KB — a direct drop-in upgrade for firmware that needs more code space.
The datasheet is available from NXP under the base product number MKL27Z32; it covers the full KL2x family electrical specifications, timing, and package drawings.
The MKL27Z32VFM4 is rated at 48 MHz, which is the maximum core clock for this Cortex-M0+ device.
