Ramtron Launches Fast and Flexible Versa 8051 MCU: A Cost-Efficient Alternative to the 16-Bit MCU
COLORADO SPRINGS, Colo.—(BUSINESS WIRE)—May 2, 2006—
Ramtron International Corporation (Nasdaq:RMTR), a
leading developer and supplier of nonvolatile ferroelectric random
access memory (FRAM) and integrated semiconductor products, today
introduced the VRS51L2070, a fast and flexible 8051-based
microcontroller that delivers the power and speed of a 16-bit MCU
without migrating from an 8-bit device.
"The VRS51L2070 meets the current market demand for a high
performance MCU, without a costly investment in new architecture and
code," explains Irv Lustigman, General Manager of Ramtron Canada.
"This optimizes system performance, but keeps development costs to a
minimum."
Upgrade 8-bit designs with a high performance Versa 8051 MCU
The VRS51L2070 is the newest series in Ramtron's Versa 8051 MCU
family. This fully integrated, high performance system-on-chip
incorporates an advanced 40-MIPS, single-cycle 8051-core, 64KB Flash
with In-System/In-Application Programming, 4KB SRAM, a JTAG
program/debug interface, digital signal processing (DSP) extensions
and a robust digital peripheral set. Operating at 3.3 volts over the
entire industrial temperature range, the VRS51L2070 is ideal for
embedded data acquisition, sensor and control applications in the
industrial, medical, consumer, instrumentation and automotive markets.
VRS51L2070 Features
-- 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 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, 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 5 cycles
(at 40 MHz). The barrel shifter enables logic/arithmetic shift
operations.
-- 40MHz Precision Internal Oscillator: The VRS51L2070's internal
oscillator provides 2% accuracy and cuts system costs by
eliminating the need for an external 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.
The VRS51L2070 incorporates an array of highly configurable
digital peripherals that enable full integration and ease the load on
the processor. These include:
-- Dual UARTs with Baud Rate Generator: The universal
asynchronous receiver/transmitters operate at up to 1.25 Mbps.
Each UART 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 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 VRS51L2070 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
VRS51L2070 is available in a QFP-64 package.
Pricing and Availability
The VRS51L2070 is currently sampling and costs under $4 in volume.
