Product details
Overview
MKW36A512VHT4R from NXP Semiconductors is an AEC Q100 Grade 2 qualified Bluetooth® Low Energy 5.0 wireless microcontroller integrating an Arm® Cortex®-M0+ core (up to 48 MHz), 512 KB flash, 64 KB SRAM, and a 2.4 GHz radio supporting up to 8 simultaneous BLE connections. 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 MKW36A512VHT4R datasheet, MKW36A512VHT4R pinout, MKW36A512VHT4R application, or MKW36A512VHT4R equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options for automotive-grade BLE + CAN FD system design.
Technical Context
The MKW36A512VHT4R implements a tightly integrated SoC architecture where the Arm Cortex-M0+ core executes application firmware while the hardware-accelerated BLE 5.0 Link Layer handles packet processing, connection management, and DSM (Deep Sleep Mode) timing. Its radio supports both Bluetooth LE 5.0 (1 Mbps PHY) and Generic FSK (250/500/1000 kbps) with programmable output power (–30 to +5 dBm) and on-chip balun.
System-level integration includes a DC-DC buck converter (reducing Rx current to 6.3 mA at 3.6 V), nine low-power modes (including VLLS0 at 258 nA), FlexCAN module with 32 configurable message buffers, and dual LPUART with hardware LIN break detection - all synchronized via a shared 32.768 kHz RTC oscillator and 26/32 MHz RF reference clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKW36A512VFT4 | Same core, memory, and radio specs; uses 48-pin "wettable" HVQFN (7×7 mm) instead of LQFN - identical thermal and electrical performance but different reflow profile. | Preferred for AOI-critical automotive production lines requiring wettable flank inspection capability. | Select MKW36A512VFT4 when board-level AOI validation is mandated; otherwise MKW36A512VHT4R offers identical functionality in standard LQFN. |
| MKW35A512VFT4 | Omits FlexCAN and second LPUART; retains BLE 5.0, 512 KB flash, and AEC Q100 Grade 2 - no CAN FD or LIN support. | Suitable for pure BLE sensor nodes without vehicle bus integration, e.g., tire pressure monitors or HVAC sensors. | Choose MKW35A512VFT4 only when CAN FD and dual UART are unnecessary - avoids paying for unused IP blocks. |
Compared with MKW36A512VHT4R, MKW36A512VFT4 provides identical functionality in a wettable-flank package for enhanced solder-joint inspection, while MKW35A512VFT4 removes FlexCAN and second LPUART to reduce cost for non-automotive BLE-only applications - neither is pin-compatible, but both share the same software SDK and toolchain.
