STMicroelectronics STM32 family microcontrollers have embedded ROM (also referred as "on-chip ROM") and include system memory [15] to facilitate empty system flashing. Certain pin combinations or sometimes efuses and/or empty flash checks force the chip to boot from ROM instead of the firmware in main flash.
Random access to data above 64K is limited to special "load far" instructions; most operations' memory operands can access at most 128K (a 16-bit base address plus 16-bit offset). Depending on the device type, the amount of RAM is in the range of 1 to 6 KiB, and the amount of ROM is 4 to 8 KiB (Low density), 16 to 32 KiB (Medium density), or 32 ...
Precisely, the Lx is a symmetric clustered architecture, where clusters communicate through explicit send and receive instructions. Each cluster executes up to 4 instructions per cycle with a maximum of one control instruction (goto, jump, call, return), one memory instruction (load, store, pre-fetch), and two multiply instructions per cycle.
STMicroelectronics NV (commonly referred to as ST or STMicro) is a European multinational semiconductor contract manufacturing and design company. It is the largest of such companies in Europe . It was founded in 1987 from the merger of two state-owned semiconductor corporations: Thomson Semiconducteurs of France and SGS Microelettronica of Italy .
The STM32 is a family of microcontroller ICs based on various 32-bit RISC ARM Cortex-M cores. [1] STMicroelectronics licenses the ARM Processor IP from ARM Holdings.The ARM core designs have numerous configurable options, and ST chooses the individual configuration to use for each design.

Numonyx was a semiconductor company making flash memories, which was founded on March 31, 2008, by Intel Corporation, STMicroelectronics and Francisco Partners. It was acquired by Micron Technology on February 9, 2010, for US$1.27 billion. [1] [2] [3]
24 MHz ARM Cortex-M3 microcontroller with 16 KB flash memory, 4 KB RAM. Manufactured by STMicroelectronics. The ARM Cortex-M is a group of 32-bit RISC ARM processor cores licensed by ARM Limited. These cores are optimized for low-cost and energy-efficient integrated circuits, which have been embedded in tens of billions of consumer devices. [1]
