STM32N655A0H3Q
MCU 32-bit ARM Cortex M55 RISC 1.8V/2.5V/3.3V 169-Pin VFBGA Tray
STMicroelectronics
STM32N6x5 general-purpose line
The STM32N6x5 microcontrollers extend the STM32 high performance portfolio and offer enhanced performance and DSP capability. They are based on the Arm® Cortex® -M55 running at 800 MHz. The Cortex® M55 is the first CPU to introduce the Arm® Helium vector processing technology, bringing DSP processing capability to a standard CPU.
STM32N6x5 MCUs are available in 142- to 264-pin VFBGA packages.
