Floating Point Co-Processor uM-FPU v3.1 SOIC

Description: 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.

Features:

• 18-pin Wide SOIC
• Supports both I²C, SPI, and serial interfaces
• 256 byte instruction buffer
• 128 general purpose 32-bit registers for storing floating point or long integer values
• 8 temporary 32-bit registers to support parentheses in calculations
• 2048 bytes Flash memory for user-defined functions
• 1024 bytes EEPROM for data storage or user-defined functions
• 10 to 20 times faster than uM-FPU V2 for all floating point operations
• Up to 70 times faster for advanced instructions
• Supports 2.7V, 3.3V and 5V supply voltage
• I²C compatible interface up to 400 kHz
• SPI compatible interface up to 15 MHz
• Expanded instruction set, matrix operations, A/D conversion, string handling
• Easy migration from uM-FPU V2
• See What's New in V3 for more details on new features
