The VRS51L2070 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 VRS51L2070’s memory sub-system features 64KB of Flashand 4352 bytes of SRAM.Support peripherals include a hardware based arithmeTIc unitcapable of performing complex mathemaTIcal operaTIons, JTAGinterface used for Flash programming and non-intrusive in-circuitdebugging/emulation, a precision internal oscillator (2% accuracy)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, 8 PWM controllers, 3 16-bit timers and 2 pulsewidth counter modules.The VRS51L2070 is powered by a 3.3 volt supply, can functionover the industrial temperature range, and is available in aQFP-64 package (See VRS51L2170 datasheet for PLCC/QFP-44packages - pin compatible with the industry standard 8051microcontroller footprint/pin-out).
