The SDP can be disabled but this requires a similar command sequence 1. You can do the same with the 28C256 if the SDP is disabled, but if it’s enabled then you need to send a specific ‘command sequence’ to the chip. With the smaller 28C16 (as used by Ben) you can write data in the same way you would with a RAM chip, just by strobing the write pin. And some of those are using larger EEPROM chips such as the 28C256.īut there’s a catch with the 28C256: it has something called software data protection (SDP), which protects data from being accidentally overwritten. ![]() And many of those are either moving on to more advanced projects or using slightly different hardware for the build. Many people are learning, like I did, about computer hardware by following Ben Eater’s 8-bit breadboard computer build.
