8051 microcontroller delivers the power and speed of a 16-bit MCU without migrating from an 8-bit device

“The VRS51L2070 meets the current market demand for a high performance MCU, without a costly investment in new architecture and code,” explains Irv Lustigman, General Manager of Ramtron Canada. “This optimizes system performance, but keeps development costs to a minimum.”

The VRS51L2070 is the newest product in Ramtron’s Versa 8051 MCU family. This fully integrated, high performance system-on-chip incorporates an advanced 40-MIPS, single-cycle 8051-core, 64KB Flash with In-System/In-Application Programming, 4KB SRAM, a JTAG program/debug interface, digital signal processing (DSP) extensions and a robust digital peripheral set. Operating at 3.3 volts over the entire industrial temperature range, the VRS51L2070 is ideal for embedded data acquisition, sensor and control applications in the industrial, medical, consumer, instrumentation and automotive markets.

VRS51L2070 features include 40MHz, Single-Cycle 8051 Processor - one of the fastest 8-bit processors on the market. Its advanced core can deliver up to 40 MIPS throughput and is instruction-compatible with standard 8051s, for smooth device migration.

The VRS51L2070 incorporates eight pulse width modulators with up to 16-bit adjustable resolution. Each PWM includes its own timer, which can also be used as general purpose timers. Other support peripherals include an I²C interface, three 16-bit general purpose timers/counters with three timer capture inputs, a watchdog timer, and 49 interrupts that share 16 interrupt vectors. The VRS51L2070 is available in a QFP-64 package.
