| Ramtron Announces VRS51L2xxx Microcontroller  Ramtron International Corporation has announced its new VRS51L2xxx, a fast and flexible 8051-based microcontroller. The VRS51L2xxx, which is the newest series in the Versa 8051 MCU family, is a fully integrated system-on-chip with an advanced 40-MIPS, single cycle 8051-core, a JTAG program/debug interface, digital signal processing (DSP) extensions and a robust digital peripheral set. Designed for embedded data acquisition, sensor and control applications in the industrial, medical, consumer, instrumentation and automotive markets, the VRS51L2xxx provides the processing power and speed to compete with a 16-bit MCU, without having to migrate from an 8-bit device.The VRS51L2xxx upgrades 8051-based systems without a costly investment in new architecture, code and development environment. Its features include an enhanced MULT/ACCU/DIV unit with 32-bit barrel shifter for quick DSP calculations 40 MHz precision internal oscillator, and communication peripherals such as a highly configurable serial port interface (SPI), 2 universal asynchronous receiver-transmitters (UARTs) with baud rate generators and micro baud adjustment, up to 14 timers/counters, an I?C, 8 pulse width modulators (PWM), 2 pulse width counter (PWC) modules and more. The VRS51L2xxx is expected to begin sampling in early May, 2006. write your comments about the article :: © 2006 Computing News :: home page |
