A Bench Built for Embedded Design

Applying a microcontroller and a serial EEPROM correctly is as important as choosing the right part, and because the performance depends on the power, the bus timing and the write scheme, the integration decides whether the board boots reliably and keeps its data. To support customers more effectively, BeiLuo has opened an FAE verification bench dedicated to Microchip PIC and AVR microcontrollers and serial EEPROM. The bench lets our engineers measure the MCU power, the EEPROM endurance and the bus timing before a customer commits to a design, turning advice into evidence.

The bench complements the stock program announced in July. Where the stocking program answers the question of whether a part is available, the new bench answers the question of whether the part will perform in a specific application. Together they let BeiLuo support a design from selection through validation, rather than only at the point of sale.

What We Measure

The bench is equipped with a programmable power supply, a precision current meter, a high-bandwidth oscilloscope with a differential probe, a logic analyzer and an environmental chamber. Engineers measure the current of an MCU in each low-power mode and the wake time, the read and the write timing of the EEPROM on the I2C and the SPI bus, the erase and program times and the stand-by current, and they run an endurance test to confirm the write-cycle life. For a boot design the bench confirms the read timing and the in-place execution, and for a data design it confirms the power-loss recovery.

MCU Power and Timing

The bench measures the current in each power mode and the wake time, which matters for a battery design, and it confirms the clock, the timer and the ADC behavior of the chosen part. For a migration it checks the peripheral and the timing against the original, which turns a porting question into a measured answer.

EEPROM Endurance and Bus Timing

A logic analyzer and a scope capture the I2C or the SPI waveform, so the bench can confirm the timing and the setup and hold margins across the temperature and the supply. An endurance test runs the erase and program cycle to confirm the write-cycle life, and a power-loss test confirms that the write scheme keeps the data safe.

From Selection to Validation

When a customer asks which device suits their design, our FAE team can now validate the recommendation on the bench. We measure the MCU power and the bus timing, or the EEPROM endurance, compare the result with the datasheet expectation and confirm the margin. The result is a design path backed by measured data, which reduces the risk of a late-stage surprise and shortens the path to a reliable design.

Boot and Data Validation

The bench can bring up a customer's board or a reference board, confirm the boot from the memory, and check the power-loss recovery of the data. That turns a boot or a data-retention question into a measured answer rather than a guess, and it supports a long warranty.

Supporting a Design End to End

The bench is a support tool, not a test house, and it is strongest when used early. A typical engagement starts with a selection question, moves to a bench check of the chosen device under the customer's conditions, and ends with a validated recommendation for the part and the layout. Because BeiLuo holds the devices in regional stock, the validated part can then move quickly to a sample and a production order.

How to Use the Bench

Customers can request a bench evaluation by sending their MCU requirements, their EEPROM bus and density, their power budget and their timing needs to the BeiLuo team. Our engineers will set up the test, measure the key parameters and share the results with a design recommendation. Because the bench and the stock program work together, a customer can validate a device on the bench and then hold production stock within the same week. The bench is one more reason to treat BeiLuo as a technical partner for Microchip devices rather than a simple parts supplier.

Results are shared as a short report with the measured power, timing and endurance, so the design team can keep the evidence with the design file and compare a later revision against it.
