Added to the range are the STM32F303 and STM32F302, both featuring a 32bit ARM Cortex-M4 core running at 72MHz. New features are said to include extra SPI and I2C communication interfaces, and a Flexible Memory Controller (FMC) with 36MHz access on 8/16bit bus for various off chip storage and LCD modules. There are also up to three 144MHz 16bit motor control timers.
The new parts can be evaluated on two hardware boards: NUCLEO-F303RE, featuring a 64pin device for fast prototyping and sampling; and STM32303E-EVAL, pictured, featuring a 100pin device.
