Explore the differences in nonvolatile memory for storage in embedded applications.
- [Voiceover] Just like RAM, non-volatile memory for storage…is also very limited in embedded systems.…This is also done on purpose because digital control…uses simple algorithms that require short programs.…So we get the same benefits of a small RAM.…It uses less area in the chip,…making it less expensive…and reducing energy consumption.…Roughly having a combined RAM and ROM space smaller than 64K…will avoid complex memory schemes…and may even help reduce the size of the stored program.…
Let's see the amount of ROM available…in the microcontroller units we saw earlier.…The Kinetis KL Series by NXP has 128 kilobytes of Flash.…This is the four times the maximum allowed program size…in the free version of Keil Microcontroller…Development Kit by Arm.…This microcontroller is expected to be used…for professional applications way beyond hobby projects.…The STM32F series by STMicro has 64k of Flash.…
That's half the size of the Kinetis.…And lastly, the ATmega328P by Microchip has 32k of ROM.…The takeaway is that ROM is usually implemented…
