FAQ

What is the maximum operating frequency and core architecture of the MKE18F512VLL16?

The MKE18F512VLL16 features an ARM Cortex-M4 core capable of running at up to 168 MHz with Thumb-2 instruction set, single-precision floating-point unit (FPU), and DSP extensions. Its 1.25 DMIPS/MHz performance rating and integrated cache deliver deterministic real-time execution for motor control and signal processing tasks. The MKE18F512VLL16 uses ARMv7-M architecture and supports full interrupt nesting via NVIC.

Does the MKE18F512VLL16 support error-correcting code (ECC) for memory reliability?

Yes, the MKE18F512VLL16 implements ECC on both its 512 KB program flash and 64 KB SRAM, enabling automatic correction of single-bit errors and detection of multi-bit errors. This feature supports functional safety requirements in industrial and automotive applications, aligning with ASIL-B readiness. ECC is hardware-enforced and requires no software overhead to maintain data integrity during operation or power transitions.

How many CAN interfaces does the MKE18F512VLL16 include, and what version do they support?

The MKE18F512VLL16 integrates two independent FlexCAN 2.0B modules compliant with ISO 11898-1, supporting bit rates up to 1 Mbps and featuring 64 configurable message buffers, flexible ID filtering, and bus-off recovery. Each module operates autonomously with dedicated mailboxes and can be configured for loopback, self-test, or normal network operation-making the MKE18F512VLL16 suitable for redundant or multi-bus automotive and industrial networks.

What low-power modes are supported by the MKE18F512VLL16, and which peripherals remain active in Stop mode?

The MKE18F512VLL16 supports seven power modes: HSRUN, Run, VLPR, Wait, VLPW, Stop, and VLPS. In Stop mode, the MCU core and most peripherals halt-but ADC, DAC, CMP, LPTMR, RTC, GPIO interrupts, and FlexIO remain operational using SIRC or OSC32 clocks. Wake-up is managed by AWIC, allowing deterministic latency under 10 µs. This enables battery-powered applications to achieve sub-10 µA quiescent current while retaining sensor responsiveness.

What is the GPIO count and high-drive capability of the MKE18F512VLL16?

The MKE18F512VLL16 provides 89 general-purpose I/O pins in its 100-pin LQFP package, all supporting interrupt generation and digital filtering. Of these, 8 pins are designated as high-drive outputs capable of sourcing or sinking up to 20 mA-enabling direct interface with LEDs, relays, and small solenoids without external driver circuitry. This reduces BOM cost and PCB area in applications such as automotive body controllers and smart lighting modules.
