The Versa Mix 8051 family (VMX51C1xxx) of mixed-signal microcontrollers includes single-chip solutions for signal conditioning, data acquisition, processing, and control applications in the industrial, medical, consumer, instrumentation, and automotive markets. 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.

It features a single-cycle 8051 processor for increased MIPS and efficiency. The device integrates an enhanced MULT/ACCU unit with a 32-bit barrel shifter, 56 KB of flash memory, and 1,280 bytes of RAM. Peripherals include up to 28 general-purpose I/Os, three timers/counters, a SPI, two 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 Versa Mix 8051 also features a five/seven-channel, 12-bit ADC that can operate at up to 10 kHz in various modes (Automatic, Single Channel, or Sequential Conversion). Also included are three 16-bit timers and four compare and capture units (CCUs). The CCUs can be configured as PWM outputs with 8- or 16-bit resolution. When filtered, the PWMs can be used as DACs. 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 Port 1 Change.

Evaluation and prototype development of the controller is facilitated through the UniVersaKit (UVK) development kit, which ships complete with Versa Ware programming interface software, a C compiler, and an assembler.

Pricing ranges from $0.80 to $5 for quantities of 10,000.
