Product details
Overview
24C00/SN from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for nonvolatile storage of calibration data, device IDs, and manufacturing parameters in space-constrained industrial and automotive systems. It operates within 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 of data retention.
For engineers reviewing the 24C00/SN datasheet, 24C00/SN pinout, 24C00/SN application, or 24C00/SN equivalent, this page provides verified electrical specs, package mapping to SOIC-8 and SOT-23-5, I²C timing compliance, endurance validation, and real-world use context for embedded ID storage and factory programming scenarios.
Technical Context
The 24C00/SN functions as an I²C slave device with fixed 4-bit device code '1010' and three don't-care address bits, enabling up to eight devices on a shared bus. Its internal address pointer auto-increments during sequential reads and supports byte write, current address read, random read, and acknowledge polling for write-cycle completion detection.
It integrates Schmitt-trigger inputs and input filtering (TSP ≤ 50 ns) for noise immunity, slope-controlled outputs to suppress ground bounce, and a VCC threshold detector that disables write logic below 3.8 V - ensuring reliable operation only within its specified 4.5–5.5 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128-bit (16 × 8) EEPROM array - sufficient for small identifiers, calibration offsets, or firmware revision stamps without over-provisioning. |
| Supply voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and automotive-grade power domains; excludes low-voltage variants (24AA00/24LC00). |
| I²C clock rate | Up to 400 kHz - enables fast configuration writes in production test environments while maintaining compatibility with legacy 100 kHz controllers. |
| Write cycle time | Typical 3 ms, max 4 ms - defines minimum inter-write interval; supports high-throughput programming when combined with ACK polling. |
| Endurance | 1 million erase/write cycles - validated for applications requiring frequent field updates (e.g., metering counters, usage logs). |
| Data retention | Greater than 200 years at +85°C - ensures long-term integrity of stored calibration or security keys across product lifetime. |
| ESD protection | >4000 V HBM - provides robust handling margin during board assembly and field service without external protection. |
Pinout & Package
24C00/SN is available in multiple packages including 8-pin SOIC (3.90 mm), 8-pin PDIP, 8-pin TSSOP, 8-pin DFN/TDFN, and 5-pin SOT-23. The /SN suffix denotes the SOIC-8 variant per Microchip's standard marking convention (DS20001178J-page 12).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SCL | Serial clock input - synchronizes all I²C transactions; requires external pull-up; Schmitt-triggered for noise rejection. |
| 2 | SDA | Bidirectional open-drain data line - transmits addresses and data; must be pulled up (2 kΩ typical for 400 kHz); supports multi-master arbitration. |
| 3 | VSS | Ground reference - common return path for all internal circuitry and I/O; connects directly to PCB ground plane. |
| 4 | NC | No connect - internally unconnected; must remain floating or tied to ground per layout best practice (no functional impact). |
| 5 | NC | No connect - same as Pin 4; no routing or termination required. |
| 6 | NC | No connect - same as Pin 4; unused in all 24C00 variants regardless of package. |
| 7 | NC | No connect - same as Pin 4; confirmed absent from functional block diagram and pin function table. |
| 8 | VCC | Positive supply - powers EEPROM core, I/O buffers, and charge pump; must be decoupled with 0.1 µF ceramic capacitor near the pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power standby | Typical 100 nA ICCS - enables always-on storage in battery-backed systems (e.g., smart sensors) with negligible drain over years. |
| I²C bus compatibility | Fully compliant with Philips I²C specification - interoperable with standard microcontroller peripherals without custom driver logic. |
| Page write capability | Single-byte write only - no page buffer; each write targets one address, simplifying firmware implementation but limiting burst throughput. |
| Factory programming support | Available via Microchip's wafer-level OTP option - allows pre-loading of unique IDs or secure keys before component shipment. |
| Automotive temperature grade | Qualified for -40°C to +125°C (E-temp) - suitable for under-hood ECUs, ADAS modules, and other harsh-environment applications. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC00-I/P | Wider VCC range (2.5–5.5 V); lower 2.5 V min enables 3.3 V-only systems; identical 128-bit capacity and I²C interface. | Preferred for mixed-voltage boards or legacy 3.3 V microcontrollers lacking 5 V tolerance. | Select 24LC00-I/P if supply rail is <4.5 V; not drop-in due to different VCC min and temp rating (I-temp only). |
| AT24C01A-PU | 1 Kbit (128 × 8) capacity; same 4.5–5.5 V range and SOIC-8 package; higher density but larger footprint-per-bit cost. | Used where future expansion headroom is needed or when consolidating multiple 128-bit stores into one device. | Choose AT24C01A-PU only if additional memory is required; pinout differs (VCC/VSS swapped), requiring PCB redesign. |
Compared with 24C00/SN, 24LC00-I/P offers broader voltage flexibility but lacks automotive qualification, while AT24C01A-PU increases capacity at the cost of non-pin-compatibility and higher unit price per bit - making 24C00/SN optimal for cost-sensitive, space-constrained E-temp applications.

FAQ
What is the operating voltage range for the 24C00/SN?
The 24C00/SN operates strictly within 4.5 V to 5.5 V. Unlike the 24AA00 (1.8–5.5 V) or 24LC00 (2.5–5.5 V), it lacks low-voltage capability - its internal charge pump requires ≥4.5 V to guarantee write functionality, and the VCC threshold detector disables programming below 3.8 V. This makes 24C00/SN ideal for 5 V industrial and automotive systems but unsuitable for 3.3 V designs.
Does the 24C00/SN support multi-device I²C addressing?
Yes, the 24C00/SN uses a fixed 4-bit device code '1010' followed by three don't-care bits, allowing up to eight 24C00/SN devices on the same I²C bus. Address selection is implemented externally via hardware straps or PCB traces - no software-configurable addressing. Each device responds only to its unique 7-bit slave address derived from the full 7-bit control byte format.
How many write cycles can the 24C00/SN endure?
The 24C00/SN is rated for more than 1 million erase/write cycles, validated through characterization (not 100% tested per DS20001178J-page 3). This endurance supports applications requiring frequent field updates - such as usage counters in medical devices or calibration recalibration in test equipment - without premature wear-out concerns.
What package does the /SN suffix indicate for 24C00/SN?
The /SN suffix explicitly denotes the 8-pin SOIC (3.90 mm) package per Microchip's official part numbering system (DS20001178J-page 12). It is distinct from /P (PDIP), /ST (TSSOP), /MN (TDFN), or /OT (SOT-23). The SOIC-8 variant offers standard surface-mount compatibility, thermal performance suitable for industrial ambient conditions, and broad reflow process support.
Can the 24C00/SN be used in automotive applications?
Yes - the 24C00/SN is qualified for the Automotive (E) temperature range (-40°C to +125°C) and meets AEC-Q200 stress testing requirements for passive components. Its 4.5–5.5 V operation, 1M-cycle endurance, and >200-year data retention make it suitable for under-hood ECUs, body control modules, and ADAS subsystems where long-term reliability is mandatory.
