The memory endianness used is implementation-defined, and the following subsections describe the possible implementations: Byte-invariant big-endian format. Arm Cortex-M7 @1 GHz + Arm Cortex-M4 @400 MHz: 289 BGA: 2 MB SRAM: 2D GPU, P x P: Parallel, MIPI: Parallel, MIPI: 4 x I 2 S, S/PDIF, DMIC: 2: 2 x Gbit/s, 1 x 10/100: 3 x CANFD:The ARM is notable for putting the program counter in the general-purpose register category, a feature which has been called “overly uniform” by noted processor architect Mitch Alsup. The Arm ® Cortex ®-M4-based STM32F4 MCU series leverages ST’s NVM technology and ART Accelerator™ to reach the industry’s highest benchmark scores for Cortex-M-based. cortex-m4.
