Frequently asked questions
What package does the MK20DN32VMP5 use — is it the same as a 64-LFBGA variant?
The confirmed package is 64-MAPBGA (5x5mm). The 64-LFBGA suffix is a different BGA variant — same pin count but different ball pitch and thermal characteristics. They are not drop-in interchangeable for reflow or rework.
How does the 8KB RAM / 32KB Flash split on this part compare to the higher-memory K20 variants for data-logging at 115200 baud?
The 8KB RAM is the constraint — Modbus-RTU at 115200 with DMA ping-pong buffers, protocol stack, and application variables will consume most of it before user data lands. Higher-memory K20 variants (128KB Flash / 16KB RAM) offer more Flash headroom but the same RAM floor, so memory footprint planning is a firmware decision regardless of which K20 variant is selected.
