The VRS51L3074 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 VRS51L3074’s memory sub-system features 64KB of Flash
and 4352 bytes of SRAM and 8192 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, a precision 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, 8 PWM controllers, three 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 QFP-44 package - pin
compatible with the industry standard 8051 microcontroller footprint.)
