From Wikipedia, the free encyclopedia. Atmel has also created an LP low power series of these chips with a “Single Cycle Core”, making the execution speed of these chips considerably faster. This programmer is suitable for programming the three popular pin Atmel processors, the 89C, 89C and the new 89C with 4 k of program memory.

Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service. Email to a Friend. Elektor recommends its business partner Eurocircuits as the company of choice for its own prototypes and volume production in selected cases.
