Wrong rail order, wrong results. ⚡

In multi-rail designs, the order your voltage rails power up (and down) matters. Get it wrong and you risk latch-up, stressed silicon, and boards that won’t boot.

Our new Power Sequencing 101 guide covers:
🔹 What goes wrong when sequencing is ignored
🔹 Discrete RC delays vs. PGOOD daisy chains vs. power sequencing ICs
🔹 Why shutdown order deserves as much attention as startup
🔹 A design checklist for your next multi-rail board

🎉 Happy 18th Workiversary to the legendary Ryan Berger! 🎉

Eighteen years is an incredible achievement! Even though he recently traded his local spot for Idaho (and yes, we miss him around the office!), Ryan is still a huge part of the Suntsu family. He’s known for his deep industry knowledge AND his ability to keep us all smiling with a perfectly timed dad joke 😂.

Thanks for always going above and beyond and for being such an awesome mentor. Here's to many more years of success (and more jokes across state lines)! Congratulations, Ryan! 🙌

🎉 Seventeen years for the one and only Robert Rangel! 🎉

Robert brings the energy every single day—whether he's dominating at the foosball table ⚽, dropping a quick, hilarious one-liner, or just generally being a legend! Thanks for always pushing us to be our best and for the non-stop laughs over the last 17 years, Robert! Here's to many more years of wins and wisdom! 🙌

Is hidden DRAM refresh power draining your battery budget? 🔋

While active read and write operations get all the attention during power modeling, background refresh cycles quietly draw continuous baseline current. At higher operating temperatures, dynamic memory cells leak charge exponentially faster, forcing refresh rates to double and driving standby power through the roof.

See how auto-refresh, self-refresh, and Partial-Array Self-Refresh (PASR) compare, and read our full technical breakdown at the link in our bio!

When a critical memory IC goes end-of-life, finding drop-in replacements quickly is essential to keep production moving.

Fab capacity shifts are forcing mature memory chips into obsolescence faster than ever. Check out our newest article to learn how engineering and procurement teams identify warning signs early, qualify Form-Fit-Function equivalents, and verify legacy inventory.

Built for speed. Rated for extremes. 🚗⚡

The SK hynix H58G66BK8QX105N packs 64Gb of LPDDR5X memory into a compact 14mm × 14mm package, delivering up to 8533 Mbps per pin and roughly 68 GB/s of peak bandwidth.

With a -40°C to +105°C operating range, it's made for automotive ADAS and cockpit systems, edge AI, robotics, and rugged industrial designs.

Our latest blog covers the key specs, power-saving features, and how LPDDR5X stacks up against LPDDR5 and DDR5.

Is an MLCC shortage threatening your assembly line?

Extended lead times of 32 to 52 weeks and rising prices are straining passive component inventories across the electronics industry.

Surging demand from AI servers and automotive electronics is shifting factory capacity away from standard components.

To protect your production schedule, engineering and purchasing teams need a clear cross-referencing strategy for drop-in replacements.

DRAM vs. Flash vs. eMMC vs. MCP: Which memory IC actually belongs in your design?

Picking the wrong memory architecture can mean pin-count bottlenecks, wasted PCB space, or excessive power draw. Here is how they stack up:

▪️ DRAM: Ultra-fast, volatile working memory.
▪️ Flash: Non-volatile storage (NOR for code ex*****on, NAND for mass data).
▪️ eMMC: Managed NAND that handles wear leveling & bad blocks on-chip.
▪️ MCP: Vertically stacked DRAM + Flash in 1 package to save ~49% board space!

Stop guessing on your BOM. Head over to the link in our bio to read the complete engineering guide on the Suntsu blog! 🔗
