RISEIC — Hong Kong Chenshengwei Electronics

Microcontrollers & Processors

Microcontrollers are the highest-turnover category in our Hong Kong stock. We hold 24,000+ MCU, MPU and SoC part numbers across ST, NXP, Renesas, Microchip, TI and Infineon — from mainstream Cortex-M0 lines down to obsolete 8/16-bit devices that franchise channels no longer list.

Whether you need production reels of current STM32 parts, a small lot of end-of-life Freescale-era silicon to keep a legacy product alive, or allocation-period spot buys, we quote from real stock with batch/date-code photos before you commit.

MCU families we cover

Our deepest lines are ARM Cortex-M (STM32F/G/H/L, NXP LPC and Kinetis, Renesas RA), 8/16-bit workhorses (PIC, AVR, HC08/HCS08, RL78) and application processors (i.MX 6/7/8, Sitara AM335x, Zynq SoC variants).

Automotive-grade and industrial-temperature suffixes are stocked separately — tell us the exact ordering code including package, temperature and reel suffix and we will match it character for character.

Buying MCUs from the open market safely

Every MCU lot we ship is photographed (top marking, label, reel) and can be tested on request: X-ray, decapsulation, solderability and functional screening through partner labs in Shenzhen.

For allocation lines we give you a live offer validity window — typically 24 to 48 hours — so you know exactly how long a quoted price and quantity hold.

Frequently Asked Questions

Do you stock obsolete or EOL microcontrollers?

Yes. EOL MCU sourcing is one of our specialties — we hold Freescale-era, legacy PIC/AVR and discontinued STM32 lines that franchise no longer carries.

Can you match an exact ordering code?

Yes. Quote us the full part number including package, temperature and tape-and-reel suffix and we confirm the exact code from stock.

What is the minimum order quantity?

One piece for sampling. Production volumes ship on tape-and-reel or tray as per the original packing.

How fast is delivery?

In-stock parts ship from Hong Kong in 1–3 working days via DHL/FedEx/UPS.

Can you test the parts before shipping?

Yes — visual, X-ray and functional testing through certified partner labs are available on request.

Do you support BOM and kitting?

Yes. Send your BOM and we quote all MCU and companion parts in one consolidated offer.

Start an RFQ or upload your BOM — our Hong Kong desk replies within 2 working hours.
