Ramtron Introduces Mixed-Signal Microcontrollers For Embedded Data Acquisition Market

Colorado Springs, CO -- Ramtron International Corporation 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 8051-based drop-in MCUs with up to128KB ISP/IAP Flash.

The VMX51C1xxx (VMX51C1020/1016) is a mixed-signal 8051 with DSP capabilities, featuring a set of on-chip peripherals for a data acquisition SoC. The VMX51C1xxx features a single-cycle 8051 processor. The device integrates a 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 I²C 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 analog peripherals such as a programmable current source, two digital potentiometers, an analog switch and an uncommitted operational amplifier.
