At 48 MHz the Cortex-M0+ core executes most single-cycle instructions, so a tight control loop fits within the interrupt latency budget. The 4 KB RAM is the real constraint: keep your state machine lean and avoid large lookup tables.
Yes, the MKL04Z32VLC4 and MKL05Z32VLC4 share the same 32-LQFP footprint and pinout, so you can drop in the MKL05 part for additional features like a 16-bit ADC without a board revision.
Yes, the MKL04Z32VLC4 is a direct drop-in replacement for the MKL04Z16VLC4 — same package, pinout, and peripheral set — with double the Flash (32 KB vs 16 KB). No board changes needed.
The MKL04Z32VLC4 datasheet is available from NXP's website under the Kinetis KL0 series documentation. The base product number is MKL04Z32.
The MKL04Z32VLC4 runs at 48 MHz on its ARM Cortex-M0+ core, which is the maximum clock speed for this device.
