Ramtron Launches Versa Mix 8051 Mixed-Signal Microcontrollers

12/15/2005 - Ramtron International Corporation (Nasdaq: RMTR), the leading supplier of non-volatile ferroelectric semiconductor products, has launched the Versa Mix 8051 family (VMX51C1xxx) of mixed-signal microcontrollers - single-chip solutions for a diverse range of signal conditioning, data acquisition, processing and control applications in the industrial, medical, consumer, instrumentation and automotive markets.

Ramtron is also introducing its Versa 8051 Family (VRS51x1xxx/5xx) of low-cost, industry standard, 8051-based drop-in MCUs with up to128KB ISP/IAP Flash, designed to simplify device migration.

About the Versa Mix 8051 family
The Versa Mix (VMX51C1020/1016) is a highly integrated, high-performance family of mixed-signal 8051 microcontrollers 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˛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.

The features of the Versa Mix 8051 include:

About the Versa 8051 family
Ramtron has also introduced the Versa 8051 family (VRS51x1xxx/5xxx) of low-cost, drop-in replacement 8051s that 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 the Versa Ware programming interface software, C compiler and assembler.

Pricing and availability
Ramtron MCUs are available immediately with prices ranging from $0.80 to $5.00 for quantities of 10,000.
