It is quite common that a too small subset of the state machine is implemented. In this case (the 24xx EEPROM), the subset is *small* but *sufficient*. The simplest possible case. It is really dead easy. Of course, you can make it complicated for yourself if you want shoot yourself into foot - e.g. by trying to support more different sizes (which might have different addressing), or how to share a single memory by multiple mcus (which is a rather painful spot on your leg being shot). The hard part is to figure out how to write to it effectively (avoid unnecessary waits for writes), but that depends on the application whether it's needed or not. And, this is NOT dependent on the bus - the same applies for the SPI-ish memories (e.g. the 25xx, or the 93xx). JW |
