Ramtron VMX1C1020
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. 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.| Part No. | VMX1C1020 |
