32-bit MCUs feature square-law accelerator

The TMS320F28035 /034/033/032 Piccolo microcontrollers feature a 32-bit control law accelerator floating-point math unit that operates independently of the CPU. The 60-MHz CPU and coprocessor both have direct access to on-chip peripherals.

The chips have 32 or 64 Kbytes of flash and 10 Kbytes of SRAM, 12 or 14 ePWM outputs, and a 217-ns 12-bit A/D converter. They operate from 40 to 105C, come in 64- or 80-pin packages, have I2C, LIN, and SPI interfaces, use a 2.97 to 3.63-V supply with an internal regulator or 1.71 to 1.99 V without the regulator. (From $3.50 ea/1,000 samples available now.)
