Essential for Industrial Control: EEPROM Data Storage in PIC16F Microcontrollers (Includes Ready-to-Use Code)

by

In industrial control settings, microcontroller main control boards often need to store critical data such as calibration parameters, device addresses, and operation logs. —— These data must not be lost due to power outages, and the built-in PIC16F series microcontrollers’ EEPROM perfectly meets the core requirement of “long-term power-off data retention”. I have been engaged … Read more

Embedded Storage Technology (Part 3): EEPROM

EEPROM is an Electrically Erasable Programmable Read-Only Memory with non-volatile characteristics, widely used for storing device parameters. Its core is based on a floating-gate transistor structure, allowing for byte-level erasure and writing (with a lifespan of 100,000 to 1,000,000 cycles). Compared to EPROM, it does not require ultraviolet light for erasure, making it more convenient … Read more

The 'Memory Palace' in Microcontrollers: What are ROM and RAM?

For those new to microcontrollers, the terms “ROM” and “RAM” can be quite confusing. Both are storage areas, but why are they divided into two? Some say ROM is “dead memory” and RAM is “live memory”; while this is not incorrect, it is too vague. Whether it’s the 51 microcontroller, STM32, or the ATmega328P used … Read more
