Key Differentiators
- Higher 250 MHz speed grade vs 200 MHz sibling (vs PIC32MZ2048EFH064T-I/PT)
- Industrial temperature grade with tape-and-reel packaging (vs PIC32MZ2048EFH064-250I/PT)

- Graphics peripheral optimization not present in EF family (vs PIC32MZ2048EFG064T-I/PT)
Design Notes
The PIC32MZ2048EFH064T-250I/PT requires a 3.3V nominal supply (2.3V-3.6V operating range) with separate analog and digital supply pins (VDD/AVDD and VDDCORE). Decouple each VDD pin with 100 nF ceramic capacitors placed within 5 mm of the pin, plus a bulk 10 uF tantalum or ceramic capacitor near the package. Estimated: the part consumes approximately 70-90 mA active at 250 MHz plus 30-50 mA peripheral current when USB, Ethernet, and CAN are all active. Use an LDO with at least 200 mA capacity and low output noise to power VDDCORE for clean ADC performance.
High-speed USB and Ethernet signals require careful PCB layout. Route USB D+/D- as a 90-ohm differential pair with length matching within 2 mm, keep traces over a continuous ground plane, and place the 12 MHz crystal within 5 mm of the OSCI/OSCO pins with short traces and a ground guard ring. For Ethernet, route the MII/RMII signals with impedance control and isolate the PHY magnetics from noisy digital traces. The TQFP-64 exposed pad (if present, per package variant) should be soldered to a ground pad for thermal dissipation.
Estimated: The PIC32MZ EF family requires programming via ICSP (In-Circuit Serial Programming) using PGECx/PGEDx pins - do not tie these pins to ground or VDD in production designs, leave them accessible for firmware updates. The dual-panel Flash requires careful linker configuration to ensure code is placed in the correct panel for live updates. A common mistake is omitting a 32.768 kHz secondary crystal on SOSC/SOSCI pins for RTCC (Real-Time Clock Calendar) operation - if RTCC is used, both 12 MHz primary and 32.768 kHz secondary crystals are required.
At 250 MHz active CPU with all peripherals running, the TQFP-64 package with theta_JA of approximately 38 C/W can dissipate up to 2.6 W before reaching the +85C industrial limit (Estimated: power = 1.5 W typical active, junction temperature rise = 1.5 W * 38 C/W = 57C above ambient). For automotive applications using the E-grade variant (+125C max), provide adequate PCB copper pour connected to the exposed pad (if applicable to the TQFP variant) and consider airflow for sustained high-CPU-load applications. Use MPLAB X IDE power estimation tools to validate thermal budgets.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - choose the E-grade (PIC32MZ2048EFH064T-250E/PT) variant for automotive temperature range, though AEC-Q100 automotive qualification status for the EF family was not confirmed in the verified data and should be validated against the latest Microchip qualification reports.
