It features FlexCAN with CAN FD support up to 3.2 Mbps, dual LPUART with LIN, and operates from 1.71–3.6 V across –40 to 105 °C - deployed in automotive digital key and wireless firmware update systems.
For engineers reviewing the MKW36A512VFT4R datasheet, MKW36A512VFT4R pinout, MKW36A512VFT4R application, or MKW36A512VFT4R equivalent, this page delivers verified technical context, real-world use cases, validated alternatives, and supply-ready availability details for automotive-grade BLE + CAN FD embedded designs.
Technical Context
The MKW36A512VFT4R implements a dual-clock RF subsystem with 26/32 MHz crystal support for BLE 5.0 and Generic FSK modes, plus a dedicated 32.768 kHz oscillator for precise low-power timing. Its radio achieves –95 dBm sensitivity at 1 Mbps BLE and –99 dBm at 250 kbps GFSK (h=0.5), with programmable TX output from –30 to +5 dBm.
On-chip peripherals include a DC-DC converter (Buck/Bypass), nine low-power MCU modes (including VLLS0 at 258 nA), AES-128 hardware acceleration, TRNG, and 8 KB FlexRAM for EEPROM emulation - all coordinated via a Crossbar-Lite switch and AIPS-Lite interconnect to support concurrent BLE stack execution, CAN FD messaging, and sensor data acquisition.
