Ramtron Introduces the First FRAM-Enhanced 8051 MCU; Groundbreaking Nonvolatile Data Storage/Processing System.COLORADO SPRINGS, Colo. -- Ramtron International Corporation (Nasdaq:RMTR RMTR Redesigned Missile Tracking Radar ), a leading developer and supplier of nonvolatile ferroelectric random access memory (storage) Ferroelectric Random Access Memory - (FRAM) A type of non-volatile read/write random access semiconductor memory. FRAM combines the advantages of SRAM - writing is roughly as fast as reading, and EPROM - non-volatility and in-circuit programmability. (FRAM (1) (Ferroelectric RAM) See FeRAM.
(2) (Ferromagnetic RAM) A non-volatile memory that records microscopic bits on a magnetic surface. See MRAM.
FRAM - Ferroelectric Random Access Memory ) and integrated semiconductor products, today launched the VRS51L3074, the market's first 8051-based microcontroller with nonvolatile FRAM memory. Ramtron has added FRAM into its fast and flexible Versa 8051s for a quick and reliable nonvolatile data storage and processing system that only a FRAM-enhanced MCU can provide.
"The VRS51L3074 represents an advance that could fundamentally alter the microcontroller landscape by providing all the advantages of FRAM on an MCU," explains Irv Lustigman, General Manager of Ramtron Canada. "This is the first in a series of planned products leading to a microcontroller based entirely on FRAM, where FRAM will be used for program, data and register memory, eliminating the need for Flash and SRAM See static RAM.
SRAM - static random-access memory altogether."
FRAM instead of Flash/EEPROM for nonvolatile data storage
FRAM simplifies the design cycle by eliminating the code overhead accompanying Flash data storage, and the limited endurance and drawn out write cycles of Flash/EEPROM. Unlike Flash, FRAM bytes can be modified without first erasing an entire sector, rendering it easier to use. And unlike Flash/EEPROM, FRAM provides virtually unlimited read/write cycles and fast data writes.
The VRS51L3074 combines 8KB of FRAM memory with a fully-integrated, high-performance system-on-chip. Features include an advanced 40-MIPS, single-cycle 8051-core, 64KB Flash with In-System/In-Application Programming, 4KB SRAM, a JTAG (Joint Test Action Group) An IEEE standard for boundary scan technology. See scan technology.
JTAG - Joint Test Action Group program/debug interface, digital signal processing See DSP.
Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). (DSP) extensions and a robust digital peripheral set. Operating at 3.3 volts over the entire industrial temperature range, the VRS51L3074 offers the ideal embedded data acquisition solution, targeting a wide array of applications from sensors and metering to industrial control, instrumentation and medical devices.

40MHz, Single-Cycle 8051 Processor: This is one of the fastest 8-bit processors on the market. Its advanced core can deliver up to 40 MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. throughput and is instruction-compatible with standard 8051s, for smooth device migration.
MULT/ACCU/DIV Unit with 32-bit Barrel Shifter: This hardware calculation engine significantly outperforms 8-bit processors when executing DSP operations (FIR filtering, sensor output linearization In mathematics and its applications, linearization refers to finding the linear approximation to a function at a given point. In the study of dynamical systems, linearization is a method for assessing the local stability of an equilibrium point of a system of nonlinear differential , multiple-byte arithmetic operations, etc). It performs 16-bit signed multiplication and 32-bit addition in one cycle (at 40 MHz) and 16-bit signed division in five cycles (at 40 MHz). The barrel shifter enables logic/arithmetic shift operations.
40MHz Precision Internal Oscillator: The VRS51L3074's internal oscillator provides better than 2% accuracy and cuts system costs by eliminating the need for an external crystal oscillator.
JTAG Interface: For user-friendly and quick device programming and real-time, in-circuit debugging/emulation of the user application without the need for a costly emulator.
Dual UARTs with Baud Rate Generator: The universal asynchronous receiver/transmitters operate at up to 1.25 Mbps. Each UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice incorporates a dedicated baud rate generator with 16-bit resolution and 4-bit micro baud rate adjustment.
Enhanced SPI: The communication speed on the serial peripheral interface (communications, hardware) Serial Peripheral Interface - (SPI) A serial interface in which a master device supplies clock pulses to exchanges data serially with a slave over two data wires (Master-Slave and Slave-Master). can be configured up to 20 Mbps and transactions are adjustable from 1 to 32 bits.
PWCs: Two pulse width counter modules provide advanced timer control, simplifying event duration measurement.
PWMs: The VRS51L3074 incorporates eight pulse width modulators with up to 16-bit adjustable resolution. Each PWM includes its own timer, which can also be used as general purpose timers.
Other support peripherals include an I2C interface, three 16-bit general purpose timers/counters with three timer capture inputs, a watchdog timer, and 49 interrupts that share 16 interrupt vectors. The VRS51L3074 is available in a QFP-64 package.
Pricing and Availability
The VRS51L3074 is currently sampling and costs under $5 in volume.
