The VRS550 and the VRS560 are both low cost 8-bit
microcontrollers
based
on
microcontroller family architecture. They are pin-to-pin
compatible and drop-in replacements for most 8051
MCUs. The VRS550 and VRS560 have 8kB and 16kB,
respectively of Flash memory. Both devices have 256
bytes of RAM memory.
the
standard
80C51
The hardware features of these devices and their re-
programmability make them suitable for a wide range of
applications.
These VRS550 and VRS560 are both available in
PLCC-44 and QFP-44 packages in the Industrial
temperature range. The Flash memory can be
programmed using programmers available from Goal
Semiconductor
or
other
programmers.
