Allows advanced mathematical functions to be performed. Includes serial I/O support and NMEA sentence parsing.

The uM-FPU V3.1 chip easily interfaces to virtually any
microcontroller using a SPI™ or I2C™ interface.
Many microcontrollers used in embedded systems lack floating
point support, but a wide range of sensors available today
require additional computations or data transformation to
provide accurate results.
Advanced operations and fast execution allows the uM-FPU
V3.1 chip to outperform comparable software math libraries. It
also provides Flash memory and EEPROM for storing userdefined
functions and data, and 128 32-bit registers for floating
point and integer data.
