Ramtron International has previewed its new VRS51L2xxx at the Embedded Systems Conference in San Jose, California. The VRS51L2xxx, which is the newest series in the Versa 8051 MCU family, is a fully integrated, high performance 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 Embedded Systems Conference is the ideal forum to preview our new high performance 8051s to design engineers and journalists,” said Irv Lustigman, General Manager of Ramtron Canada. “The VRS51L2xxx is the first in a series of exciting developments we have planned for our Versa 8051 and Versa Mix 8051 MCU product lines.”

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, a cost-cutting, 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 I²C, 8 pulse width modulators (PWM), 2 pulse width counter (PWC) modules and more.

The VRS51L2xxx is expected to begin sampling in early May.
