F-RAM-enhanced MCU drops into standard 8051-compatible sockets

The VRS51L3174 from Ramtron International is an 8051-based MCU featuring 8 kbytes of non-volatile Ferroelectric Random Access Memory (F-RAM), which can be deployed directly in embedded designs using industry-standard 44-pin Quad Flat Package (QFP) sockets.

With the added advantage of F-RAM’s high write speeds, low power consumption and high endurance, the VRS51L3174 combines 40MIPS performance at 40MHz CPU speed, DSP extensions incorporating a 32-bit barrel shifter, 64 kbyte Flash with in-system/in-application programming, and 4 kbyte on-chip SRAM.

Integrated peripherals include a hardware-based arithmetic unit, a JTAG interface for Flash programming and non-intrusive in-circuit debugging and emulation, a 40MHz internal oscillator, and a watchdog timer. Rich digital peripherals, including an enhanced and fully-configurable SPI bus, I²C interface, dual UARTs with dedicated baud-rate generators, three 16-bit timers, 8 PWM controllers each with a 16-bit timer, and two pulse-width counter modules, support communication and control of external devices.

Development support is via the VersaKit-30xx plug-and-play evaluation and development kit, which includes a development board, USB-JTAG programming/debugging interface, and supporting software and documentation.
