Floating Point Co-Processor uM-FPU v3.1
From bildr
The new uM-FPU v3.1 by Micromega has all the proven features of the v3 with some interesting new GPS NMEA string parsing features. The uM-FPU v3.1 chip interfaces to virtually any microcontroller using a SPI, I2C, or serial interface, making it ideal for applications requiring floating point math, including sensor readings, robotic control, GPS, data transformations and other embedded control applications. The uM-FPU v3.1 chip supports 32-bit IEEE 754 compatible floating point and 32-bit integer operations. The uM-FPU v3.1 is RoHS compliant, operates from a 2.7V, 3.3V or 5V supply, and is available in 18-pin DIP, SOIC-18 or QFN-44 packages. Interface examples are available for BASIC Stamp, Javelin, PICAXE, 16F87x, ARMmite, and ARMexpress controllers.Floating Point Operations:
