Preliminary Technical Brief

Rev 1.1

FRAM Enhanced High Performance 8051 MCU

General Description ____________________

Features ______________________________

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.

•

8051 High Performance Single Cycle Processor

(Operation up to 40 MIPS)

8KB Nonvolatile FRAM (Ferroelectric Random

Access Data Memory, In-System/ln-Application

Programmable)

Based on

powerful 40-MIPS, single-cycle, 8051

•

64KB Flash (Program Memory, In-System/ln-

Application Programmable)

4K + 256 Bytes of SRAM (4K Bytes - Program Or

Data Memory)

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

JTAG Interface for FRAM/Flash Programming &

Non-Intrusive Debugging/In-Circuit Emulation

MULT/DIV/ACCU Unit including Barrel Shifter

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.
