Product details
Overview
MKW41Z512VHT4R from NXP Semiconductors is a Bluetooth Low Energy v4.2 and IEEE 802.15.4–compliant multi-standard SoC featuring an ARM Cortex-M0+ core running at up to 48 MHz, 512 KB on-chip Flash, 128 KB SRAM, and integrated 2.4 GHz transceiver with -95 dBm BLE sensitivity and programmable output power from -30 dBm to +3.5 dBm - deployed in portable health monitors, smart home sensors, and battery-powered remote controls.
For engineers reviewing the MKW41Z512VHT4R datasheet, MKW41Z512VHT4R pinout, MKW41Z512VHT4R application, or MKW41Z512VHT4R equivalent, key selection criteria include dual-protocol radio support (BLE + 802.15.4), ultra-low-power VLLS0 mode (182 nA), integrated DC-DC buck/boost, hardware AES-128 acceleration, and 48-pin LQFN package with on-chip balun for minimal external RF components.
Technical Context
The MKW41Z512VHT4R integrates a single-chip 2.4 GHz transceiver supporting three concurrent physical-layer modes: BLE v4.2 (GFSK, 1 Mbps), IEEE 802.15.4 (O-QPSK, 250 kbps), and generic FSK (250/500/1000 kbps) - each with dedicated hardware accelerators for link-layer processing and dual-PAN address matching. Its radio subsystem uses a shared single-ended RF port with integrated balun and supports 26 MHz or 32 MHz crystal references depending on active protocol.
System-level timing relies on multiple clock domains: 32.768 kHz XTAL for RTC and BLE timing accuracy in low-power modes; 26/32 MHz XTAL for radio operation; and FLL-synthesized 48 MHz for MCU execution. Power management includes nine low-power modes, with VLLS0 enabling wake-up via GPIO or RTC while consuming only 182 nA - enabled by internal LPO and retained SRAM state across deep sleep.

FAQ
What radio standards does the MKW41Z512VHT4R support?
The MKW41Z512VHT4R supports Bluetooth Low Energy v4.2 (GFSK, 1 Mbps), IEEE Std. 802.15.4-2011 (O-QPSK, 250 kbps), and generic FSK (250/500/1000 kbps) - all with dedicated hardware accelerators. It does not support BLE 5.0, Sub-1 GHz, or Wi-Fi. Each standard operates independently with its own timing reference: 26 MHz for BLE/FSK and 32 MHz for 802.15.4.
Does the MKW41Z512VHT4R include an integrated DC-DC converter?
Yes, the MKW41Z512VHT4R includes an integrated DC-DC converter supporting Buck (2.1–4.2 V), Boost (0.9–1.795 V), and Bypass modes. In Buck mode, it reduces typical Rx current to 6.8 mA at 3.6 V; in Boost mode, it enables single alkaline cell operation across its full voltage range. An external inductor is required for Buck/Boost operation.
What is the lowest power consumption mode of the MKW41Z512VHT4R?
The MKW41Z512VHT4R achieves 182 nA in Very-Low-Leakage Stop (VLLS0) mode - the deepest sleep state retaining SRAM content and waking in under 1 µs via GPIO or RTC. This mode uses the internal 1 kHz LPO oscillator and requires no external crystal, making it ideal for multi-year battery operation in intermittent-sensing applications.
How many simultaneous BLE connections does the MKW41Z512VHT4R support?
The MKW41Z512VHT4R supports up to two simultaneous hardware BLE connections - configurable as master-slave, master-master, or slave-slave - using dedicated BLE Link Layer engines. This enables concurrent communication with a smartphone and a peripheral device without CPU scheduling overhead or protocol stack arbitration.
What security features are implemented in hardware on the MKW41Z512VHT4R?
The MKW41Z512VHT4R implements AES-128 hardware acceleration, True Random Number Generator (TRNG), 80-bit unique chip identifier, 40-bit unique MAC sub-address, flash memory protection with execute-only sectors, and Bluetooth LE v4.2 Secure Connections - all verified in NXP's certified protocol stacks. These features enable FIPS-compliant cryptographic operations without software-based entropy or key derivation bottlenecks.
