12 Versa Mix 8051 Mixed-Signal MCU Overview The VMX51C1020 is a fully integrated mixed-signal microcontroller that provides a “one-chip solution” for a broad range of signal conditioning, data acquisition, processing, and control applications.
The VMX51C1020 is based on a powerful single-cycle, RISC-based, 8051 microprocessor with an enhanced MULT/ACCU unit that can be used to perform complex mathematical operations.
On-chip analog peripherals such as: an A/D converter, PWM outputs (that can be used as D/A converters), a voltage reference, a programmable current source, an uncommitted operational amplifier, digital potentiometers and an analog switch makes 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 interface, UARTs and a J1708/RS-485/RS-422 compatible differential transceiver, enables total system integration.
