Atmel

Atmel microcontrollers and memory in stock at YILUDA TECH. Eight Atmel lines are held as 100% original, new and unused material — 8051 and AVR microcontrollers, serial EEPROM, data flash and parallel flash.

What is on the shelf

8051 microcontrollers — AT89C52 in DIP-40 and AT89C5224JC in PLCC-44.
AVR microcontrollers — ATMEGA16A in TQFP-44.
Serial EEPROM — AT24C64CN-SH-T in SOP-8.
Data flash — AT45DB011D-SSH-T in SOP-8.
Parallel flash — AT29C020-70JU in PLCC-32.

DIP, PLCC, SOP and TQFP mounting are all represented — useful when a board was designed for a through-hole part and the socket is still there.

Why these particular parts

The 8051 and classic AVR lines are still designed into industrial timers, vending equipment, lighting control and instrumentation. They are also among the first parts to go allocation-only when a fab moves on. Keeping PLCC and DIP variants available matters because those packages are rarely second-sourced.

Ordering notes

Speed grade and package are part of the Atmel code — AT89C52 at 24 MHz is not the same device as the 12 MHz version.
For EEPROM and flash, state the density and interface you need if the exact suffix is not listed.
Worldwide shipping from Shenzhen by DHL, FedEx or UPS.

Buyer questions

Are the DIP parts old stock?

They are new and unused. Where a part has been in the channel for years the date code reflects manufacture, not resale — we will state it on request.

Can you supply a programmed MCU?

Parts ship blank. Programming and firmware loading are handled by the customer.
