MKE04Z64VLK4R 概覽
The NXP MKE04Z64VLK4R is a Kinetis KE04 family microcontroller built on the ARM Cortex-M0+ core running at 48 MHz, integrating 64 KB of flash program memory and 8 KB of SRAM in an 80-pin LQFP package. It is part of NXP's Kinetis E series designed for cost-sensitive, high-reliability applications in electrically noisy industrial and consumer environments, offering enhanced ESD/EMC robustness versus general-purpose Cortex-M0+ devices.
What is a Cortex-M0+ microcontroller? The Cortex-M0+ is ARM's smallest and most energy-efficient 32-bit microcontroller core, designed for embedded systems that require deterministic real-time response, low power consumption, and a simple instruction set. An MCU (microcontroller) integrates a CPU core, program flash, SRAM, and peripherals (analog, timers, communication) into a single chip. The KE04 family sits at the low end of the Kinetis portfolio, optimized for 5 V-tolerant I/O and high-noise immunity rather than maximum performance - it competes in the same space as small PIC, AVR, and ST Cortex-M0 parts.
Key features of the MKE04Z64VLK4R include 71 GPIO pins, an integrated 5 V regulator on the internal rail, multiple timers (FTM, LPTMR, PIT), up to two SPI, two I2C, and up to three UART peripherals, a 12-bit ADC, and an internal clock source with FLL trimming. The 5 V-tolerant I/O and ESD/EMC hardening make it suitable for white goods, motor control boards, and factory automation endpoints where the system is exposed to switching transients and discharge events.
Architecturally, the KE04 combines a 2-stage Cortex-M0+ pipeline with a single 32-bit flash controller and a peripheral bridge exposing the Kinetis peripheral set to the core. The 80-LQFP footprint (14x14 mm) provides sufficient pin count for full peripheral breakout while remaining hand-solderable for prototype work.
Typical applications include BLDC and stepper motor controllers in appliances, industrial sensor interfaces, HVAC control boards, low-end point-of-sale terminals, and any 5 V system replacing legacy 8-bit designs. The wide supply range and integrated analog simplify design-in versus discrete solutions.
When designing with this part, ensure your SWD/JTAG header is brought out to a standardized 2x5 0.05" connector to allow field firmware updates. Designers familiar with other Kinetis parts will recognize the peripheral set; KE04 differs from KE02 mainly in flash density and ADC channel count.
This page synthesizes distributor pricing, drop-in alternatives (including same-package KE-series variants and cross-package KE04 pinouts), and practical design notes not found in the standard NXP product brief.

According to the KE04 reference manual, the core includes a single-cycle hardware multiplier and NVIC interrupt controller optimized for embedded cost-sensitive designs.
What package does MKE04Z64VLK4R use and how many pins?
The MKE04Z64VLK4R comes in an 80-pin LQFP package (14x14 mm, 0.65 mm pitch, designated LQFP-80 / LK suffix). 71 pins are available as GPIO, with the remainder dedicated to power, ground, and the SWD interface. The LK suffix specifically denotes the LQFP-80 form factor versus the LD (LQFP-64) and LH (LQFP-64 industrial) variants.
What is the operating voltage range of MKE04Z64VLK4R?
The MKE04Z64VLK4R operates from 2.7 V to 5.5 V supply, with 5 V tolerance on most digital I/O pins. This wide supply range is a defining feature of the Kinetis E series and lets the MCU drop directly into legacy 5 V analog/digital systems that cannot tolerate 3.3 V-only parts. Internal regulators derive the 1.8 V core rail from VIN.
Where can I buy MKE04Z64VLK4R and what is the lead time?
The MKE04Z64VLK4R is available from authorized NXP distributors including DigiKey, Mouser, and Heisener.

Stock levels can be checked in real time on DigiKey and Mouser product pages. For production volumes we recommend confirming allocation directly with NXP to avoid spot-market substitution.
What is the difference between MKE04Z64VLK4R and MKE04Z64VLD4?
The MKE04Z64VLK4R comes in an 80-pin LQFP (14x14, LK suffix), while the MKE04Z64VLD4 uses a 64-pin LQFP (LD suffix). Both share the same Cortex-M0+ core at 48 MHz, 64 KB flash, and 8 KB SRAM, but the LK variant exposes more peripherals and GPIOs (71 vs roughly 58). They are not pin-to-pin compatible due to the different pin counts.
What is the difference between MKE04Z64VLK4R and S9KEAZ64AVLK?
The MKE04Z64VLK4R is a standard Kinetis KE04 part, while the S9KEAZ64AVLK is the KEA (Kinetis EA) family successor in the same 80-pin LQFP footprint. Both deliver 48 MHz Cortex-M0+, 64 KB flash, and similar peripherals; the KEA adds CAN connectivity and improved low-power modes. Migrating from KE04 to KEA is generally drop-in for the 80-LQFP variant.
What can replace MKE04Z64VLK4R?
The best drop-in replacements for MKE04Z64VLK4R in the same 80-LQFP package include the same-family MKE04Z64VQH4R (industrial temp, equivalent footprint) and the cross-family S9KEAZ64AVLK (KEA family successor with CAN). For a different vendor in the same footprint, the Microchip SAMD20 family variants in compatible LQFP packages offer ARM Cortex-M0+ with similar core speed, though they require firmware porting.
What is the best Microchip equivalent for MKE04Z64VLK4R?
The closest Microchip (formerly Atmel) cross-vendor alternative for MKE04Z64VLK4R is the ATSAM D20 series in 80-pin LQFP, which provides a 48 MHz Cortex-M0+ core with comparable flash and peripheral count. However, it is a different pinout so it is not a drop-in - PCB redesign is required. For pin-to-pin compatibility within the NXP ecosystem, the S9KEAZ64AVLK is a more direct swap.
When should I choose MKE04Z64VLK4R over S9KEAZ64AVLK?
Choose MKE04Z64VLK4R for existing designs already qualified on the KE04 silicon and where BOM churn is undesirable; the part remains active and supported. Choose S9KEAZ64AVLK for new designs where adding CAN connectivity and improved low-power modes is beneficial. Both share the 80-LQFP footprint, easing migration either direction.
Is MKE04Z64VLK4R suitable for motor control applications?
Yes, the MKE04Z64VLK4R is well-suited for BLDC, stepper, and simple brushed motor control in appliance and industrial designs. The KE04 integrates FTM (FlexTimer) PWM channels with complementary outputs and dead-time insertion, plus a 12-bit ADC for back-EMF sensing and current measurement. Its 5 V I/O tolerance lets it directly drive 5 V gate drivers without level shifters.
How do I program MKE04Z64VLK4R?
The MKE04Z64VLK4R is programmed via the standard ARM 2-wire SWD (Serial Wire Debug) interface using tools such as NXP S32 Design Studio with PE Micro, Segger J-Link, or PEMicro OpenSDA on supported evaluation boards. The Kinetis flash programming routines in the SDK handle sector erase, program, and verify operations across the 64 KB flash array.
Where can I download the MKE04Z64VLK4R datasheet?
The MKE04Z64VLK4R datasheet (KE04P64M80SF0 reference) is available as a free PDF download from the official NXP product page at nxp.com. The companion KE04 reference manual documents the full peripheral register set and is required alongside the datasheet for serious firmware development. Both documents are linked from the MKE04Z64VLK4R product page on NXP's website.
Where can I find the MKE04Z64VLK4R pinout?
The MKE04Z64VLK4R pinout for the 80-pin LQFP package is documented in the NXP datasheet KE04P64M80SF0, including a pin assignment table and package mechanical drawing. For quick reference the package is 14x14 mm body with 0.65 mm pitch. Each pin's function (GPIO, peripheral alternate, power, or reset) is listed in the datasheet pinout table.

選型指南
Choose the MKE04Z64VLK4R for new BLDC or appliance control designs needing 5 V-tolerant I/O and moderate compute at low cost - it remains the most cost-optimized Kinetis E series part in 80-LQFP. For designs requiring CAN, choose S9KEAZ64AVLK in the same footprint (KEA family). For designs needing full -40C to +105C industrial temp, choose MKE04Z64VQH4R. For designs where pin count and BOM consolidation matter most, choose the 100-LQFP MKE04Z64VLL4R variant. The 80-LQFP KE04 family also lets you downgrade to 64-pin (MKE04Z64VLD4) if fewer GPIOs are needed and smaller PCB space is available.

- Drop-in same-package migration to KEA family (對比S9KEAZ64AVLK)
- Industrial temperature grade option (對比MKE04Z64VQH4R)
設計說明
Decouple VDD pins with a 100 nF ceramic cap placed within 5 mm of each VDD/VSS pair. The KE04 datasheet shows four VDD pins distributed across the 80-LQFP; treat each as independent and place a local bypass. Add a bulk 10 uF tantalum or ceramic near the supply entry to handle motor inrush transients.
Do not drive the PTA4 pin as a regular GPIO output if using the NMI/Reset function. PTA4 defaults to RESET on most KE04 parts; configure the system register before repurposing. Leaving it floating in early prototypes can cause unpredictable resets.
Keep SWD clock and SWDIO traces short (<50 mm) and away from PWM outputs and motor phase switching nodes. Use a 4-layer PCB with dedicated ground plane under the MCU. Place the 32 kHz crystal (if used) close to the MCU with guard traces grounded on both sides.
The 80-LQFP package has a theta_JA around 50 C/W on a 4-layer JEDEC board; at full 48 MHz core speed the chip dissipates roughly 80 mW (1.8 V x 45 mA core). Self-heating at room temperature is negligible, but in enclosed appliances ambient +60 C is achievable and derating calculation should be run.
