The VRS51L3xxx is ideal for real-time data collection and storage: The high-performance core controls peripherals and gathers data, and its on board digital signal processing (DSP) functions process the data, which is then stored in the F-RAM.
- VRS51L3074: 8KB of F-RAM for easy access, fast writes, and essentially unlimited endurance. Comes in an RoHS-compliant QFP-64 package.
- VRS51L3174: 8KB of F-RAM in an RoHS-compliant QFP-44 package that is compatible with industry-standard 8051 MCUs for easy device migration.
- VRS51L3072 - 2KB F-RAM in an RoHS-compliant QFP-64 package.
Plus:
- 40MHz, Single-Cycle 8051 Processor: Advanced core delivers up to 40 MIPS throughput. Instruction-compatible with standard 8051s for smooth device migration.
- MULT/ACCU/DIV Unit with 32-bit Barrel Shifter: Outperforms 8-bit processors on DSP operations.
- 40MHz Internal Oscillator: No need for an external crystal oscillator.
- USB-JTAG Interface: For user-friendly, quick device programming and real-time in-circuit debugging/emulation.
- Dual UARTs with Baud Rate Generator: Operate at up to 1.25 Mbps and incorporates a dedicated baud rate generator with 20-bit equivalent resolution.
- Enhanced SPI: Speed can be configured up to 20 Mbps and transactions are adjustable from 1 to 32 bits.
- PWCs: For advanced timer control, simplifying event duration measurement.
- PWMs: With 16-bit adjustable resolution and timers that can be used as a general purpose timers.
- Operates at 3.3 volts over the entire industrial temperature range.
The VRS51L3xxx is ideal for saving system status, data logging, and storing nonvolatile
variables in a range of applications from sensors and meters to industrial
controls, instrumentation and medical devices.
