NXP Semiconductors MKW41Z512VHT4

Overview

MKW41Z512VHT4 from NXP Semiconductors is a Bluetooth Low Energy v4.2 and IEEE 802.15.4–compliant SoC integrating an ARM Cortex-M0+ core, 512 KB Flash, 128 KB SRAM, and a multi-standard 2.4 GHz transceiver with -95 dBm BLE sensitivity and programmable -30 dBm to +3.5 dBm output power. It operates across 0.9–4.2 V and supports dual-PAN 802.15.4 in wearable health monitors and smart home sensors.

For engineers reviewing the MKW41Z512VHT4 datasheet, MKW41Z512VHT4 pinout, MKW41Z512VHT4 application, or MKW41Z512VHT4 equivalent, this page delivers verified radio performance specs, MCU clocking options (26/32 MHz crystal support), low-power mode current (182 nA in VLLS0), integrated AES-128 acceleration, and confirmed 48-pin LQFN package mapping - all tied explicitly to MKW41Z512VHT4.

Technical Context

The MKW41Z512VHT4 implements a hardware-accelerated BLE Link Layer with two independent connection engines and dedicated IEEE 802.15.4 packet processing logic - enabling concurrent dual-PAN operation without host CPU intervention. Its RF section integrates an on-chip balun and single-ended bidirectional RF port, supporting GFSK (BT=0.3/0.5/0.7) and O-QPSK modulations at 250/500/1000 kbps data rates.

System-level power optimization includes a configurable DC-DC converter operating in Buck (2.1–4.2 V), Boost (0.9–1.795 V), or Bypass modes, plus nine MCU low-power states - with VLLS0 consuming only 182 nA and full-run current at 6.8 mA (Rx) / 6.1 mA (Tx @ 0 dBm). Clock architecture supports 26 MHz and 32 MHz crystals for BLE/FSK, and 32 MHz exclusively for 802.15.4.

FAQ

What radio standards does the MKW41Z512VHT4 support, and are they hardware-accelerated?

The MKW41Z512VHT4 supports Bluetooth Low Energy v4.2 (with two simultaneous hardware connections), IEEE 802.15.4-2011 (O-QPSK, dual-PAN), and Generic FSK (250/500/1000 kbps). All three are hardware-accelerated: BLE Link Layer uses dedicated connection engines, 802.15.4 employs packet processor logic, and FSK modulation is handled in RF baseband - freeing the Cortex-M0+ core for application tasks. This is confirmed in the MKW41Z/31Z/21Z Data Sheet Rev. 4, Sections 3.2 and 4.3.

Does the MKW41Z512VHT4 include an integrated balun, and what RF interface does it use?

Yes, the MKW41Z512VHT4 integrates an on-chip balun and uses a single-ended bidirectional RF port (labeled RF_IN/OUT). This eliminates the need for external baluns, matching networks, and harmonic filters - reducing RF bill-of-materials by 6–8 components and PCB area. The port requires only a 50 Ω controlled-impedance trace to the antenna, as specified in Section 3.2 and Figure 1 of the MKW41Z/31Z/21Z Data Sheet Rev. 4.

What is the operating temperature range and package type for the MKW41Z512VHT4?

The MKW41Z512VHT4 uses a 48-pin Laminate QFN package (7 × 7 × 0.98 mm, 0.5 mm pitch) and is rated for -40 °C to +105 °C operation. This extended temperature range is explicitly stated for the "Laminate-QFN" variant in Section "Operating Characteristics" of the MKW41Z/31Z/21Z Data Sheet Rev. 4, distinguishing it from the WLCSP variant (MKW41Z512CAT4), which is limited to -40 °C to +85 °C.

How much Flash and SRAM memory does the MKW41Z512VHT4 provide, and is it partitioned?

The MKW41Z512VHT4 provides 512 KB of on-chip Flash memory and 128 KB of SRAM. Flash is implemented as two equal 256 KB blocks, enabling execute-while-program (EWP) operation - code can run from one block while the other is erased or programmed. Both memory types are accessible to the Cortex-M0+ core and protocol stacks, with flash sector-level execute-only protection to prevent unauthorized readout, as detailed in Section 3.3 of the MKW41Z/31Z/21Z Data Sheet Rev. 4.

What low-power modes and current consumption values are guaranteed for the MKW41Z512VHT4?

The MKW41Z512VHT4 supports nine low-power modes, including VLLS0 (Very-Low-Leakage Stop) with a guaranteed 182 nA current draw at 3.0 V and 25 °C. In active modes, typical Rx current is 6.8 mA (DC-DC buck, 3.6 V), and Tx current is 6.1 mA at 0 dBm output. These values are measured under defined conditions and documented in Sections 6.2.1 and 7.2.5 of the MKW41Z/31Z/21Z Data Sheet Rev. 4 - confirming suitability for multi-year battery operation.
