The 48 MHz core runs a Modbus RTU stack, polls 20 analog channels, and refreshes a segment LCD in the same loop without external SDRAM or a multi-layer PCB.
NXP is the manufacturer. The MKL33Z32VLK4 is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time. No minimum order quantity is imposed for standard procurement.
The core runs at 48 MHz. This is the maximum clock for the ARM Cortex-M0+ core in the Kinetis KL3 series, sufficient for real-time control loops, Modbus communication, and segment LCD refresh without external memory.
The MKL36Z64VLK4 (64 KB Flash) is the pin-compatible step-up within the same 80-LQFP footprint and industrial temperature range. It shares the same peripheral set and supply voltage range, making it a drop-in replacement for designs that outgrow 32 KB of code space.
The MKL33Z32VLK4 is available through independent distribution. Submit an RFQ for current pricing and availability; the part is quoted to order with no minimum quantity restriction.
