Specs side by side
2 parts compared · 14 differing specs across 14 total parameters.
| Parameter | ||
|---|---|---|
| Supply voltage | - | Minor differences live in the margins of the datasheets (timing at the fast modes, internal write cycle specifics) - the standard behaviors are common. |
| Memory & Peripherals | - | At the same density and package, the prefixes interchange in the field daily; the open-drain bus pull-ups (10k class) and the WP pin convention are what repairs actually get wrong. |
| Case | DIP-8 / SOIC-8 / TSSOP-8 | DIP-8 / SOIC-8 |
| Compatibility Level | - | 100% Drop-in (Zero Code Change) |
| Component Category | I2C Serial EEPROM | - |
| Core & Architecture | - | The family was designed as an industry standard: the same 1010 device address, the same pin map, the same bus behavior under every vendor prefix - the reason a 24Cxx is a specification as much as a part number. |
| Firmware Notes | - | The WP pin deserves the same attention as the address pins: the write-protect behavior depends on the design and sometimes on the vendor internal default - a board that will not save settings after a memory swap usually has WP where the new part does not like it. |
| Hardware Notes | - | DIP-8/SOIC-8 shared across vendors. |
| 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. | - |
