Description
The AT80F51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K
bytes of QuickFlash Memory. The device is manufactured using Atmel’s high density
nonvolatile memory technology and is compatible with the industry standard MCS-
51™ 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 AT80F51 is a powerful microcomputer which
provides a highly flexible and cost effective solution to many embedded control appli-
cations.
