Datasheet of 243 KB in PDF for the 93C46B, a 1 Kbit serial EEPROM of the 93-series Microwire family; the B suffix generally identifies a version with fixed word organisation, which the document confirms. These small memories are found holding settings in TVs, car radios, dashboards and network devices. The sheet supplies pinout, voltage range and instruction set, needed to choose the correct mode on a programmer. Always read and store the original dump before rewriting, since the data is often device-specific.
