uM-FPU64 Floating Point Coprocessor

The uM-FPU64 extends Micromega's family of coprocessors to provide support for IEEE 754 compatible 64-bit and 32-bit floating point and integer calculations, expanded digital I/O and analog input capabilities, and support for local peripheral devices.  The uM-FPU64 can be interfaced to a wide range of popular microcontrollers to provide extensive floating point capabilities, and optionally control a subsystem of local peripherals. It can also be configured as a stand-alone microcontroller for embedded applications.

The uM-FPU64 is compatible with the instruction set of Micromega's popular uM-FPU V3.1 32-bit floating point coprocessor. Advanced instructions are provided for fast data transfer, matrix operations, FFT calculations, serial input/output, NMEA sentence parsing, string handling, digital input/output, analog input, and control of local devices.

I2C or SPI compatible interface. Operates from 3.3V supply, with 5V tolerant pins. Available in 28-pin DIP, SOIC-28 or TQFP-44 packages.
