之前有读者问过类似这样的问题： 今天就来围绕EEPROM 和 FLASH展开描述，希望能解决你心中的疑惑。 ROM的发展 ROM：Read-Only Memory，只读存储器。 以非破坏性读出方式工作，只能读出无法写入信息，信息一旦写入后就固定下来，即使切断电源，信息也不会丢失 ...

The 28c16 is an eeprom with 2048 bytes of storage. So, 11 address pins, 8 I/O pins, 3 mode pins and 5V and ground pins. Using just 6 gpio pins, my writer can write all 2048 bytes in just under a ...

Almost all AVR microcontrollers have built-in Electrically Eraseable Programmable Read Only Memory (EEPROM).The advantage of EEPROM is that even when the microcontroller is turned off, data stored in ...

Last week I spent most of my leisure time studying nonvolatile memory chips. The result was a better understanding of Arduino’s EEPROM. This might look like novice work, but I hope my thoughts will ...

We’re always excited to get a new chip or SIM card to interface, but our enthusiasm is often dampened by the prototyping process. Interfacing any chip usually means breadboarding a circuit, writing ...
