Technical Context

The MKE04Z64VLH4 implements an Arm Cortex-M0+ core with single-cycle 32×32 multiplier and single-cycle I/O port access. Its clock system combines a 32.768 kHz crystal oscillator, 4–24 MHz external resonator support, and internal FLL with 37.5 kHz pre-trimmed reference for stable 48 MHz system clock generation.

Power management includes Run/Wait/Stop modes with sub-100 µA Stop current (5 V), LVD with selectable thresholds (2.56–4.4 V), and RTC powered by 1 kHz LPO. Analog subsystem comprises one 16-channel 12-bit SAR ADC (hardware-triggered, Stop-mode capable) and two ACMPs each with 6-bit DAC and programmable reference input.

FAQ

What is the maximum operating frequency of the MKE04Z64VLH4?

The MKE04Z64VLH4 operates at up to 48 MHz system clock frequency, derived from its internal FLL locked to either an external crystal (4–24 MHz) or the 37.5 kHz internal reference. This frequency is fully supported across the –40 to 105°C temperature range and 2.7–5.5 V supply voltage, with timing compliance verified per Table 7 of the KE04 Sub-Family Data Sheet Rev. 6.

Does the MKE04Z64VLH4 support hardware debugging?

Yes, the MKE04Z64VLH4 includes a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards. It supports full-speed debugging, flash programming, and real-time trace at up to 24 MHz SWD_CLK frequency, with defined setup/hold timing (J9/J10) and signal integrity requirements per Table 11 in the official datasheet.

What analog peripherals are integrated into the MKE04Z64VLH4?

The MKE04Z64VLH4 integrates one 16-channel 12-bit SAR ADC with hardware triggering and Stop-mode operation, two analog comparators (ACMP) each featuring a 6-bit DAC and programmable reference input, and a buffered bandgap reference (VBG = 1.16 V ±20 mV). These are fully characterized from –40 to 105°C per Tables 4 and 6.4.1–6.4.2.

What is the minimum supply current in Stop mode for the MKE04Z64VLH4?

In Stop mode with no peripherals enabled, the MKE04Z64VLH4 draws 2 µA typical (105 µA max) at 5 V and –40 to 105°C ambient, as specified in Table 5. With ADC active in Stop, current rises to 86 µA typical; with ACMP enabled, it adds only 12 µA - enabling ultra-low-power sensor wake-up architectures.

Is the MKE04Z64VLH4 pin-compatible with other KE04 family members?

Yes, the MKE04Z64VLH4 shares identical 64-pin LQFP (10 mm × 10 mm) mechanical and electrical pinout with MKE04Z128VLH4 and MKE04Z64VQH4, as confirmed in Section 8.2 "Device pin assignment" of the KE04 Sub-Family Data Sheet Rev. 6. Signal multiplexing and voltage tolerances match across these variants.
