Description
The AT80F52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K
bytes of QuickFlash memory. The device is manufactured using Atmel’s high density
nonvolatile memory technology and is compatible with the industry standard 80C51
and 80C52 instruction set and pinout. The on-chip QuickFlash allows custom codes to
be quickly programmed in the factory. By combining a versatile 8-bit CPU with Quick-
Flash on a monolithic chip, the Atmel AT80F52 is a powerful microcomputer which
provides a highly flexible and cost effective solution to many embedded control appli-
cations.
