Description
The AT87LV51 is a low-voltage, high-performance CMOS 8-bit microcontroller with
4K bytes of QuickFlash One-Time Programmable (OTP) Read Only 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 the program memory to be user programmed by a conven-
tional nonvolatile memory programmer. By combining a versatile 8-bit CPU with
QuickFlash on a monolithic chip, the Atmel AT87LV51 is a powerful microcontroller
that provides a highly flexible and cost-effective solution to many embedded control
applications.
