Ramtron International Corporation launched the VRS51L3174, an 8051-based microcontroller with 8 KB of nonvolatile FRAM memory that drops into industry standard 44-pin QFP sockets for easy device migration. The device’s features include an advanced 40-MIPS, single-cycle 8051-core, 64KB Flash with in-system/in-application programming, 4KB SRAM, digital signal processing (DSP) extensions and a robust digital peripheral set. Operating at 3.3V over the entire industrial temperature range, it targets a wide array of advanced applications from sensors and metering to industrial control, instrumentation and medical devices. Other support peripherals include an I²C interface, three 16-bit general purpose timers/counters with three timer capture inputs, a watchdog timer, and 49 interrupts that share 16 interrupt vectors. The device is available in a QFP-44 package that is pin-compatible with standard 8051 MCUs. The VRS51L3174 is currently sampling and costs under $5 for quantities of 10,000.
