| Parameter | ||
|---|---|---|
| Supply voltage | - | Same bus; the change is in the byte sequence, not the volts. |
| Memory & Peripherals | - | The classic symptom of the missed change: a firmware written for one-byte addressing reads or writes the wrong cell after a 24C32 is fitted - the "it saved but reads garbage" report. |
| Case | DIP-8 / SOIC-8 / TSSOP-8 | DIP-8 / SOIC-8 |
| Compatibility Level | - | Functional Equivalent |
| Component Category | I2C Serial EEPROM | - |
| Core & Architecture | - | Beyond 2K bits the family changes address protocol: the word address becomes two bytes - and the address pins return to hardware duty (A0-A2 useful again for up to eight devices). |
| Firmware Notes | - | Crossing the 24C16 to 24C32 line is a firmware event, not a footprint event: update the addressing, then the pin-based cascade options come back. |
| Hardware Notes | - | Same 8-pin body again - the trap of the whole family. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The 24Cxx row is the settings, calibration and counter memory of a generation of instruments, monitors, meters and chargers: a 2-wire serial EEPROM whose 8-pin footprint never changes from 24C02 to 24C64, and whose address pins A0, A1 and A2 change MEANING at almost every density step. The base device address is always the industry-standard 1010 pattern, the SDA/SCL bus is open-drain with pull-ups, and the WP pin guards the array - and the substitutions that fail are almost never electrical: they are firmware assumptions about word addressing, or a cascade of devices whose address pins just became memory address bits. | - |

| Role In Circuit | Original Reference Part | - |
| Sourcing Advantage | - | Stocked; pair the quote with the addressing the firmware implements. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
