The uM-FPU V2 floating point coprocessor is easily interfaced with virtually any microcontroller to provide support for 32-bit IEEE 754 compatible floating point and 32-bit long integer calculations. It can be connected using either an I2C or SPI compatible interface. The uM-FPU uses an internal oscillator and requires no external components. It is available in an 8-pin DIP or SSOP-20 SMT package. Documentation and support software is available for a variety of microcontrollers.
