Versa Mix 8051 Mixed-Signal MCU
Overview
The VMX51C1016 is a fully integrated mixed-signal
microcontroller that provides a “one-chip” solution for
a broad range of control, data acquisition and
processing applications. The VXM1016 is based on a
powerful, single-cycle, RISC-based 8051 processor
with an enhanced MULT/ACCU unit that can be used
to perform complex mathematical operations. The
device includes 56KB of Flash memory and 1280
bytes of RAM.
On-chip analog peripherals such as: an A/D
converter, PWM outputs (that can be used as D/A
converters), a voltage reference and an analog switch
make the VMX51C1020 ideal for analog data
acquisition applications.
The inclusion of a full set of digital interfaces such as
an enhanced, fully configurable SPI, an I²C, UARTs
and a J1708/RS-485 compatible differential
transceiver, enables total system integration.
The VMX51C1016 operates on a 5 volt supply and is
available in a QFP-44 package.
