Ramtron Introduces the Versa Mix 8051 Family of Highly Integrated Mixed-Signal Microcontrollers for the Embedded Data Acquisition Market
COLORADO SPRINGS, Colo.—(BUSINESS WIRE)—Dec. 13, 2005—
Ramtron International Corporation (Nasdaq:RMTR), the
leading supplier of nonvolatile ferroelectric semiconductor products,
today launched the Versa Mix 8051 Family (VMX51C1xxx) of mixed-signal
microcontrollers -- single-chip solutions for a diversity of signal
conditioning, data acquisition, processing and control applications in
the industrial, medical, consumer, instrumentation and automotive
markets. Ramtron also offers its Versa 8051 Family (VRS51x1xxx/5xx) of
low-cost, industry standard, 8051-based drop-in MCUs with up to 128KB
ISP/IAP Flash, designed to simplify device migration.

About the Versa Mix 8051 Family
The VMX51C1xxx (VMX51C1020/1016) is a highly integrated,
high-performance, mixed-signal 8051 with DSP capabilities, featuring a
comprehensive set of on-chip peripherals for a complete data
acquisition SoC. The VMX51C1xxx features a single-cycle 8051 processor
that provides an average of eight times more processing power than
standard 8051s for increased MIPS and efficiency. The device
integrates an enhanced MULT/ACCU unit with 32-bit barrel shifter, 56KB
of Flash and 1280 bytes of RAM. Peripherals include up to 28 general
purpose I/Os, 3 timers/counters, an SPI, 2 UARTs, an I(2)C and an
RS-485/RS-422/J1708 compatible transceiver, which enables data
transmission over long distances via a twisted pair cable. The
VMX51C1xxx operates at 5 volts and is available in QFP-64 (VMX51C1020)
and QFP-44 (VMX51C1016) packages.
Aimed at control applications that require signal conditioning,
the VMX51C1020 also incorporates an array of analog peripherals such
as a programmable current source, two digital potentiometers, an
analog switch and an uncommitted operational amplifier.
Features of the Versa Mix 8051
A/D Converter -- This 5/7-channel, 12-bit A/D converter can
operate at up to 10kHz in various modes: automatic, single channel, or
sequential conversion.
Complex DSP operations -- The enhanced hardware arithmetic unit
performs 16-bit x 16-bit multiplication and 32-bit addition in one
cycle. This enables major performance gain over typical 8051 devices
when executing mathematical and DSP operations -- an ideal feature for
applications that require digital filtering or other recursive
calculations.
Serial Port Interface -- This fully-configurable master/slave
interface can automatically address up to four slave devices and can
be configured to handle 1 to +32-bit data transactions.
UART with Baud Rate Generator -- UARTs operate at over 460kbps and
each incorporate a 10-bit baud rate generator freeing up the
timers/counters for other uses. UARTs can be connected to the
integrated differential transceiver.
Timers/CCU units -- The VMX51C1xxx includes three 16-bit timers
and 4 compare and capture units (CCUs). The CCUs can be configured as
PWM outputs with 8-bit or 16-bit resolution. The PWMs, when filtered,
can be used as D/A converters. Three of the CCUs provide a capture
input that can be used to trigger the Timer 2 Capture. Additionally,
the device includes input pins and an interrupt on the Port1 Change.
Power-saving features -- Power saving features include a clock
control unit, individual power controls for each peripheral and
processor IDLE and STOP modes.
About the Versa 8051 Family
Ramtron's Versa 8051 Family (VRS51x1xxx/5xxx) of low-cost, drop-in
replacement 8051s are ideal for a diversity of applications that
require small to large amounts of program/data memory with nonvolatile
data storage and/or code/field based firmware upgrade capability,
coupled with streamlined/comprehensive peripheral support. Versa 8051s
include up to 128KB Flash memory and 1KB RAM. Devices operate at
either 3.3 or 5 volts and are available in 44-pin PLCC/QFP and also
40-pin DIP packages.
Development/Programming Tools
Evaluation and prototype development of Versa Mix 8051 and Versa
8051 MCUs is facilitated through Ramtron's UVK (UniVersaKit)
development kit, which ships complete with Versa Ware programming
interface software, C compiler and assembler.
Pricing and Availability
Ramtron MCUs are available immediately with prices ranging from
$.80 to $5 for quantities of 10,000.
