VRS51L3074

The VRS51L3074 is a FRAM enhanced, high performance, 8051-based microcontroller coupled with a fully integrated array of peripherals for addressing a broad range of embedded design applications.

Based on a powerful 40-MIPS, single-cycle, 8051 microprocessor, the VRS51L3074's memory sub-system includes 8KB of FRAM (high endurance, nonvolatile RAM), 64KB of Flash and 4352 bytes of SRAM.

Support peripherals include a hardware based arithmetic unit capable of performing complex mathematical operations, a JTAG interface used for FRAM/Flash Programming and non-intrusive in-circuit debugging/emulation, a precision internal oscillator (2% accuracy) and a watchdog timer.

Communication and control of external devices is facilitated via an assortment of digital peripherals which include an enhanced fully configurable SPI bus, an I2C interface, dual UARTs with dedicated baud rate generators, 8 PWM controllers, 3 16-bit timers and 2 pulse width counter modules.

The VRS51L3074 is powered by a 3.3 volt supply, can function over the industrial temperature range, and is available in a QFP-64 package (see VRS51L3174 for PLCC44 and QFP-44 packages pin-compatible with the industry standard 8051 microcontroller footprint).
