Product details
Overview
MKW35Z512VHT4 from NXP Semiconductors is an ultra-low-power Bluetooth® Low Energy 5.0 wireless microcontroller integrating a 48 MHz Arm® Cortex®-M0+ core, 512 KB flash, 64 KB SRAM, and a 2.4 GHz radio supporting up to 8 simultaneous BLE connections. It delivers –95 dBm receiver sensitivity at 1 Mbps BLE, programmable TX output from –30 dBm to +5 dBm, and operates across –40 to 105 °C for industrial sensor nodes and medical wearables.
For engineers reviewing the MKW35Z512VHT4 datasheet, MKW35Z512VHT4 pinout, MKW35Z512VHT4 application, or MKW35Z512VHT4 equivalent, this page provides verified technical context, exact package mapping (48-pin LQFN, 7×7 mm), confirmed low-power modes (VLLS0 @ 258 nA), BLE 5.0 Link Layer hardware acceleration, and validated alternative options for wireless MCU selection.
Technical Context
The MKW35Z512VHT4 implements a single-ended RF architecture with integrated balun and shared bidirectional RF port, enabling minimal external component count. Its radio supports Bluetooth LE 5.0 PHY (1 Mbps) and Generic FSK at 250/500/1000 kbps with modulation indices of 0.32–1.0 and GFSK BT = 0.3/0.5/0.7.
System-level power management includes DC-DC buck mode (6.3 mA Rx / 5.7 mA Tx @ 0 dBm), nine low-power modes, and hardware-accelerated AES-128 and TRNG for secure over-the-air updates. Unlike MKW36Z, it omits FlexCAN, second LPUART, and FlexRAM - confirming its role as a cost-optimized BLE-only node.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, 48 MHz - enables real-time BLE stack execution with deterministic latency. |
| Memory | 512 KB flash + 64 KB SRAM - sufficient for BLE host stack, application firmware, and OTA update staging. |
| Radio Sensitivity | –95 dBm @ 1 Mbps BLE - ensures robust link budget in noisy industrial environments. |
| TX Output Power | –30 dBm to +5 dBm programmable - allows precise range/power trade-off without external PA/LNA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKW36Z512VHT4 | Includes FlexCAN module, second LPUART, and 8 KB FlexRAM; identical 48-pin LQFN package. | Required for CAN-connected industrial gateways needing dual-interface (BLE + CAN FD) bridging. | Select MKW36Z512VHT4 only if CAN FD or dual UART functionality is mandatory; otherwise MKW35Z512VHT4 reduces cost and complexity. |
| nRF52840 DK | ARM Cortex-M4F core, 1 MB flash, USB interface; QFN48 but different pinout and no integrated DC-DC. | Better suited for USB-dongle designs or applications requiring floating-point math; lacks industrial temp rating. | Choose nRF52840 DK for prototyping with USB HID or Thread/Matter stacks; MKW35Z512VHT4 is preferred for production-grade industrial deployment. |
Compared with MKW36Z512VHT4, MKW35Z512VHT4 removes CAN FD and FlexRAM to reduce cost and power while retaining identical BLE 5.0 performance and package footprint; versus nRF52840 DK, it offers superior industrial qualification, integrated DC-DC, and lower VLLS0 current - critical for sealed, battery-operated field devices.

FAQ
What is the maximum number of simultaneous Bluetooth LE connections supported by MKW35Z512VHT4?
MKW35Z512VHT4 supports up to 8 simultaneous Bluetooth LE hardware connections in any master/slave combination, as defined in the Bluetooth LE 5.0 Link Layer hardware implementation. This capability is confirmed in the MKW36Z/35Z Data Sheet Rev. 9, Section 2.2, and applies identically to MKW35Z512VHT4. The hardware connection table resides in dedicated RAM, enabling deterministic connection handling without CPU intervention.
Does MKW35Z512VHT4 include CAN FD support like the MKW36Z variant?
No, MKW35Z512VHT4 does not include CAN FD support. The orderable parts table explicitly lists "N" for CAN FD qualification under MKW35Z512VHT4, while MKW36Z512VHT4 shows "Y". The FlexCAN module is exclusive to the KW36Z family; MKW35Z512VHT4 omits this peripheral to optimize cost and power for pure BLE applications.
What package type and dimensions does MKW35Z512VHT4 use?
MKW35Z512VHT4 uses a 48-pin LQFN package with 7×7 mm body size and 0.5 mm pitch, documented in package drawing 98ASA00694D1. It features wettable flanks for automated optical inspection (AOI) of solder joints. This matches the MKW36Z512VHT4 footprint, enabling layout reuse when upgrading functionality.
What is the minimum supply voltage for MKW35Z512VHT4 in VLLS0 mode?
MKW35Z512VHT4 operates in VLLS0 mode down to 1.71 V on VDD_0, VDD_1, and VDDA pins, as specified in Section 6.2.1 of the MKW36Z/35Z Data Sheet Rev. 9. Below this threshold, brownout reset (LVD) triggers to prevent unreliable flash or SRAM operation. The DC-DC buck mode requires ≥2.1 V input but bypass mode supports down to 1.71 V.
How does the integrated balun in MKW35Z512VHT4 affect RF design?
The MKW35Z512VHT4 integrates a balun optimized for 2.4 GHz operation, enabling direct connection of a single-ended PCB antenna or matching network to the RF_IN/OUT pin. This eliminates external balun components and associated layout sensitivity, reducing RF bill-of-materials by 4–6 parts and simplifying certification testing for FCC/CE compliance.
