VRS51L3072

The VRS51L3072 is a 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 VRS51L3072's memory sub-system features 64KB of Flash and 4352 bytes of SRAM and 2048 Bytes of nonvolatile FRAM (ferroelectric random access memory) memory.

Support peripherals include a hardware based arithmetic unit capable of performing complex mathematical operations, a JTAG interface for Flash programming and non-intrusive in-circuit debugging/emulation, an internal oscillator, and a watchdog timer. Communication and control of external devices is facilitated via an assortment of digital peripherals such as an enhanced, fully configurable SPI bus, an I²C interface, dual UARTs with dedicated baud rate generators, three 16-bit timers, 8 PWM controllers each with a 16-bit timer, and 2 pulse width counter modules.

The VRS51L3072 operates from 3.0 to 3.6 volts over the industrial temperature range and is available in a QFP-64 package.
