Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

What are the key design constraints when integrating the Nuvoton EZ1116 into a mixed-voltage system where I/O signals operate at 3.3V while the core logic runs at 5V?
The EZ1116 operates with a supply voltage range of 4.5V to 5.5V, making it inherently compatible with 5V systems but not directly tolerant of 3.3V I/O levels. If interfacing 3.3V signals, level-shifting circuitry or bidirectional voltage translators must be used to prevent damage or undefined states. Direct connection of 3.3V inputs may result in logic threshold mismatches and unreliable operation due to the device’s input high-level minimum of 0.7 × VCC (typically ~3.15V at 4.5V). This design consideration is critical for signal integrity and long-term reliability in industrial environments.
Can the EZ1116 be safely powered from a 5V unregulated line with transient spikes up to 6V during power-up?
No, the EZ1116 has an absolute maximum supply voltage rating of 5.5V. Transient spikes exceeding this limit—even briefly—can compromise internal protection diodes and lead to permanent device failure. A TVS diode or Zener clamp should be implemented at the supply input to suppress overvoltage events, especially in automotive or industrial applications where load dump or switching transients are common.
Is the EZ1116 suitable for battery-powered portable devices due to its power consumption characteristics?
The EZ1116 consumes typical active current in the tens of mA range under normal operation, which may exceed acceptable limits for low-power portable applications. While it supports a standby mode with reduced power, continuous use without sleep cycles would drain batteries rapidly. For battery-operated systems requiring µA-level sleep currents, alternative ultra-low-power microcontrollers would be more appropriate.
How does the EZ1116 compare to the Microchip ATmega8 in terms of clock source options and configuration flexibility for embedded timing applications?
Unlike the ATmega8, which supports multiple internal oscillators (1MHz, 8MHz) and external crystal/capacitor configurations, the EZ1116 relies solely on an external crystal oscillator or ceramic resonator. This simplifies design but eliminates the benefit of internal clock calibration, requiring precise frequency control. Migration from ATmega8 to EZ1116 necessitates careful evaluation of startup time, jitter tolerance, and whether internal RC oscillators are sufficient for the target application’s timing accuracy.
Are there known reliability concerns with the DIP8 package of the EZ1116 in high-vibration industrial environments?
The DIP8 package uses through-hole leads that provide mechanical strength but lack the solder joint robustness of surface-mount alternatives like QFN or SOIC. In high-vibration settings—such as factory automation or transportation systems—thermal cycling and mechanical stress can fatigue solder joints between the PCB and component header pins. For such environments, conformal coating and strain relief measures are recommended, though migration to a more rugged SMD package may be preferable if board space allows.
What precautions should be taken when replacing legacy 8-bit MCUs like the EZ1116 in existing DIP sockets?
Replacing the EZ1116 in a socketed design requires verifying compatibility of pinout, interrupt structure, and peripheral mapping with the new part. Since many replacement candidates have different register layouts or instruction sets, firmware may require significant rework. Additionally, socket contact resistance and oxidation over time can degrade signal integrity; periodic cleaning or using gold-plated sockets is advisable for long-term field deployments.
Can the EZ1116 drive capacitive loads directly on GPIO pins without additional buffering?
The EZ1116’s GPIO drivers are not designed for heavy capacitive loads. Driving loads exceeding 50pF without series termination can cause excessive rise/fall times, EMI issues, and potential latch-up during fast transitions. For driving LEDs, relays, or long traces, an external buffer transistor or dedicated driver IC should be used to maintain signal integrity and protect the microcontroller.
Does the EZ1116 support brown-out detection (BOD) and at what voltage threshold?
Yes, the EZ1116 includes a configurable brown-out detection circuit with thresholds typically available at 4.3V, 4.0V, and 3.7V relative to VCC. Enabling BOD prevents erratic behavior during power-down events by triggering a reset if the supply drops below the selected level. However, this feature must be enabled via software and cannot be disabled once configured, so firmware initialization must account for it early in the boot sequence.
Is it possible to use the EZ1116 in a hot-swappable power system without risking latch-up or reset loops?
Hot-swapping with the EZ1116 carries risk due to its 5V-only supply domain and sensitive input protection structures. Without reverse-current protection and soft-start sequencing, plugging in a powered system could trigger parasitic thyristor-like latch-up in CMOS inputs. A current-limiting resistor or hot-swap controller with controlled inrush is strongly advised to mitigate this risk in systems supporting live insertion.
What are the implications of using the EZ1116 with a slow-rising power supply (e.g., from a boost converter)?
The EZ1116 requires VCC to reach at least 4.5V before stable operation begins. With very slow ramp rates (<1V/ms), the internal power-on reset (POR) may timeout or fail to generate a clean reset pulse, leading to unpredictable startup behavior. Adding a capacitor to the RESET pin or ensuring adequate ramp speed ensures reliable initialization, particularly when sourcing power from dynamic regulators like DC-DC converters.
