The VRS51L3072 is a high performance, 8051-based microcontrollercoupled with a fully integrated array of peripherals for addressing abroad range of embedded design applicaTIons.Based on a powerful 40-MIPS, single-cycle, 8051 microprocessor,the VRS51L3072’s memory sub-system features 64KB of Flashand 4352 bytes of SRAM and 2048 Bytes of nonvolaTIle FRAM(ferroelectric random access memory) memory.Support peripherals include a hardware based arithmeTIc unit capableof performing complex mathemaTIcal operations, a JTAG interface forFlash programming and non-intrusive in-circuit debugging/emulation,an internal oscillator, and a watchdog timer.Communication and control of external devices is facilitated via anassortment of digital peripherals such as an enhanced, fullyconfigurable SPI bus, an I²C interface, dual UARTs with dedicatedbaud rate generators, three 16-bit timers, 8 PWM controllers eachwith a 16-bit timer, and 2 pulse width counter modules.The VRS51L3072 operates from 3.0 to 3.6 volts over the industrialtemperature range and is available in a QFP-64 package.
