Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only. The functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe 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 VMX51C1016 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.
