Product details
Overview
24C00T/SN from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-overhead nonvolatile storage of calibration data, device IDs, and manufacturing traceability in space-constrained industrial systems. It operates at 4.5–5.5 V, supports 100 kHz/400 kHz clock rates, delivers typical read current of 500 µA, and guarantees >1 million erase/write cycles with >200 years data retention.
For engineers reviewing the 24C00T/SN datasheet, 24C00T/SN pinout, 24C00T/SN application, or 24C00T/SN equivalent, this page provides verified electrical specs, package mapping to SOIC-8, validated I²C timing compliance, and real-world use context for embedded ID storage, sensor calibration, and firmware configuration persistence.
Technical Context
The 24C00T/SN implements a slave-only I²C interface with fixed 7-bit address prefix '1010' and three don't-care bits, enabling up to eight devices on one bus. Its internal address pointer auto-increments during sequential reads and resets after byte writes.
It features Schmitt-trigger inputs and input filtering (50 ns spike suppression) for robust noise immunity on shared buses, plus slope-controlled outputs to minimize ground bounce. Write operations are self-timed with 3 ms typical page write time and VCC threshold protection that disables programming below 3.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128-bit (16 × 8) EEPROM array - sufficient for small ID strings, calibration offsets, or boot flags without over-provisioning. |
| VCC range | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and automotive-grade supply stability requirements. |
| I²C clock rate | 100 kHz / 400 kHz - supports legacy microcontroller peripherals and faster host polling without bus contention. |
| Write endurance | 1 million cycles - enables field-updatable parameters in industrial controllers with multi-year service life. |
| Data retention | 200+ years at +85 °C - ensures long-term integrity of stored calibration coefficients across product lifecycle. |
| Standby current | 1 µA max - minimizes quiescent power draw in always-on sensor nodes or battery-backed modules. |
| ESD protection | 4 kV HBM - withstands handling and board-level transients without external protection circuitry. |
Pinout & Package
24C00T/SN is supplied in an 8-pin SOIC package (3.90 mm body width), RoHS-compliant and Pb-free. Pin 1 is marked with a notch or dot; pin numbering follows standard SOIC convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect | Internally unconnected; must be left floating or tied to GND per layout best practice - no functional impact. |
| 2 (NC) | No-connect | Internally unconnected; unused pin - no routing or termination required. |
| 3 (NC) | No-connect | Internally unconnected; reserved for future compatibility - electrically inert. |
| 4 (VSS) | Ground reference | Primary return path for all internal circuitry; requires low-impedance connection to system ground plane. |
| 5 (SDA) | Serial data I/O | Open-drain bidirectional bus line requiring external 2–10 kΩ pull-up to VCC; handles address/data transfer and ACK/NACK signaling. |
| 6 (SCL) | Serial clock input | Master-generated clock signal synchronizing all I²C transactions; includes Schmitt trigger and noise filter for jitter tolerance. |
| 7 (NC) | No-connect | Internally unconnected; no electrical function - leave unconnected. |
| 8 (VCC) | Power supply | 4.5–5.5 V input powering EEPROM core and interface logic; bypass capacitor (0.1 µF) recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 50 mV hysteresis (VHYS ≥ 0.05 VCC) - rejects sub-50 ns noise spikes on SDA/SCL lines without external RC filtering. |
| Output slope control | Controlled rise/fall times (TR/TF ≤ 300 ns @ VCC = 5 V) - eliminates ground bounce-induced glitches during bus transitions. |
| Self-timed write cycle | 3 ms typical, 4 ms max - removes need for host wait states or polling overhead; ACK polling supported for precise timing control. |
| VCC threshold lockout | Disables write if VCC < 3.8 V - prevents partial writes and data corruption during brown-out conditions. |
| Factory programming option | Pre-loadable device-specific data (e.g., MAC address, serial number) at wafer/test stage - reduces post-silicon programming steps. |
Applications
| Industrial Sensor Calibration | Embedded Device Identity Storage |

IC Role / Device Role / Timing Role: Automotive-grade EEPROM interfacing with main ECU MCU via isolated I²C bus; supports 400 kHz operation under E-temp conditions. Use Value: Meets AEC-Q100 stress requirements for endurance and data retention, enabling recalibration without reprogramming main flash memory. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA00T/SN | Lower VCC range (1.8–5.5 V); higher standby current (100 nA typ.) but same 128-bit capacity and I²C protocol. | Better suited for battery-powered or mixed-voltage systems where 5 V rail is unavailable. | Select when operating below 4.5 V is required; not drop-in due to different VCC min specification. |
| AT24C01A-PU | 1 Kbit (128 × 8) capacity; identical SOIC-8 package and I²C timing, but higher endurance (1M vs. AT24C01A's 100K cycles per block). | Used where larger configuration space is needed, e.g., multi-parameter sensor profiles or extended logging buffers. | Choose for increased memory depth; verify VCC compatibility (2.5–5.5 V) and ensure software handles 1K addressing. |
Compared with 24C00T/SN, the 24AA00T/SN enables lower-voltage operation at the cost of reduced automotive temperature support, while the AT24C01A-PU offers 8× more memory in the same footprint but with lower endurance per memory location - critical for high-write-rate applications.

FAQ
What is the maximum clock frequency supported by the 24C00T/SN?
The 24C00T/SN supports I²C clock frequencies up to 400 kHz when operated within its specified VCC range of 4.5–5.5 V and temperature range of -40°C to +85°C. At 100 kHz, it remains functional across the full industrial temperature span but does not extend to automotive-grade operation above +85°C.
Does the 24C00T/SN require external pull-up resistors on SDA and SCL lines?
Yes, the 24C00T/SN requires external pull-up resistors on both SDA and SCL lines because its I/O pins are open-drain. For 400 kHz operation, a 2 kΩ pull-up to VCC is recommended; for 100 kHz, 10 kΩ is typical. These values ensure proper rise time and bus noise margin per I²C specification.
Can the 24C00T/SN be used in automotive applications requiring -40°C to +125°C operation?
No, the 24C00T/SN is rated only for the industrial temperature range (-40°C to +85°C). Although the 24C00 family includes an automotive-grade variant (24C00E), the 24C00T/SN suffix indicates industrial qualification. For +125°C operation, the 24C00E/SN or equivalent AEC-Q100 qualified part must be selected.
How many devices can share the same I²C bus with the 24C00T/SN?
Up to eight 24C00T/SN devices can coexist on a single I²C bus. Each uses a fixed 4-bit device code '1010' followed by three don't-care bits, allowing hardware address selection via external wiring of those bits - though the 24C00T/SN itself has no address pins, so multiple units require distinct base addresses or external multiplexing.
What happens if a write command is interrupted by a power loss on the 24C00T/SN?
The 24C00T/SN incorporates a VCC threshold detector that disables internal write logic if VCC drops below 3.8 V. This prevents partial writes and ensures data integrity - any incomplete write operation is automatically aborted, leaving the EEPROM contents unchanged and electrically valid.
