Product details
Overview
24C00-I/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 systems. It operates at 4.5–5.5 V, supports 100 kHz/400 kHz clock rates, features Schmitt-trigger inputs for noise immunity, and delivers typical standby current of 100 nA and read current of 500 µA.
For engineers reviewing the 24C00-I/SN datasheet, 24C00-I/SN pinout, 24C00-I/SN application, or 24C00-I/SN equivalent, this page provides verified electrical specs, package mapping to SOIC-8, I²C timing compliance, endurance (1M cycles), and real-world use context - all confirmed against Microchip DS20001178J.
Technical Context
The 24C00-I/SN implements a slave-only I²C interface with fixed 4-bit device code '1010' and three don't-care address bits, enabling up to eight devices on one bus. Its internal address pointer auto-increments during sequential reads and resets only on write completion or power cycle.
It uses on-chip charge-pump voltage generation for EEPROM programming, includes VCC threshold detection (3.8 V nominal) to inhibit writes during undervoltage, and relies on ACK polling - not timeout-based waiting - to detect end-of-write-cycle completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128-bit (16 × 8) EEPROM array - sufficient for small configuration tokens or factory-trimmed coefficients without over-provisioning. |
| Supply voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and excludes low-voltage operation found in 24AA00/24LC00 variants. |
| I²C clock rate | Up to 400 kHz - enables faster byte writes than 100 kHz legacy mode while maintaining compatibility with standard I²C controllers. |
| Write cycle time | Typical 3 ms, max 4 ms - defines minimum inter-write interval; requires ACK polling or fixed delay before next command. |
| Endurance & retention | 1 million erase/write cycles and >200 years data retention - validated for long-life embedded deployments with infrequent updates. |
| Operating temperature | -40°C to +85°C (Industrial grade) - qualified for use in industrial control panels, metering hardware, and factory automation interfaces. |
| ESD protection | >4000 V HBM - reduces risk of field failure due to handling or board-level ESD events in unshielded environments. |
Pinout & Package
24C00-I/SN is packaged in 8-pin SOIC (3.90 mm body width), per Microchip Drawing C04-018D. Pin 1 is marked with a notch or dot; the package is Pb-free and RoHS compliant.
| 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 externally (2 kΩ typical for 400 kHz). |
| 3 | NC | No connect - internally unconnected; must remain floating or tied to ground per layout best practice (no functional impact). |
| 4 | VSS | Ground reference - common return path for all internal circuitry and I²C bus termination. |
| 5 | NC | No connect - same as Pin 3; no internal connection; avoid routing signals or vias to this pad. |
| 6 | NC | No connect - identical functional status to Pins 3 and 5; unused in 24C00-I/SN SOIC variant. |
| 7 | NC | No connect - fourth NC pin; confirms device uses only four active terminals in this package configuration. |
| 8 | VCC | Positive supply - powers EEPROM core, I/O buffers, and charge pump; must be stable within 4.5–5.5 V during all operations. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power standby | 100 nA typical ICCS - enables battery-backed or energy-harvesting systems to retain memory state for years without measurable drain. |
| I²C timing compliance | Fully meets SMBus and Fast-mode I²C specs (400 kHz @ 4.5–5.5 V) - interoperable with microcontrollers, PMICs, and FPGAs without protocol translation. |
| Self-timed write cycle | No external timing control needed - internal oscillator manages erase/write; host only waits for ACK or polls until ready. |
| Noise-immune inputs | Schmitt-trigger + 50 ns spike filtering on SDA/SCL - eliminates false Start/Stop detection in electrically noisy industrial enclosures. |
| Factory programming option | Pre-load calibration constants or serial numbers at wafer/test - reduces post-solder programming steps and improves production throughput. |
Applications
| Smart Sensor Calibration | Industrial PLC Configuration |
|---|---|

IC Role / Device Role / Timing Role: Write-once or infrequent-write memory accessed during startup and service mode via I²C. Use Value: Meets FDA traceability requirements; immune to accidental overwrite due to VCC lockout below 3.8 V. |
Use Scenario: Saving user preferences (e.g., display brightness, language, timer defaults) in washing machines and HVAC remotes. IC Role / Device Role / Timing Role: Low-energy EEPROM written only when settings change; read at every power-up. Use Value: Maintains settings through AC power loss; 100 nA standby current extends battery life in remote controls beyond 5 years. |
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/SN | Wider VCC range (2.5–5.5 V); lower 2.5 V min enables 3.3 V system compatibility; otherwise identical pinout, timing, and memory map. | Required where main system rail is 3.3 V and 5 V is unavailable; not suitable if strict 4.5–5.5 V operation is mandated by safety standards. | Select 24LC00-I/SN only when 3.3 V operation is needed; verify VCC stability margin during brownout conditions. |
| AT24C01A-PU | 1 Kbit (128 × 8) capacity; same SOIC-8 package; 1.8–5.5 V supply; supports 1 MHz Fast-mode Plus; higher endurance (1M vs 100K cycles in older versions). | Used where future expansion to larger configuration space is anticipated; supports higher-speed buses but requires updated timing validation. | Choose AT24C01A-PU if headroom for additional parameters is needed; confirm I²C controller supports 1 MHz and updated ACK timing. |
Compared with 24C00-I/SN, the 24LC00-I/SN offers broader voltage flexibility at no cost to footprint or software, while the AT24C01A-PU trades minimal size increase for 8× more memory and faster clock support - both require revalidation of power sequencing and timing margins.

FAQ
What is the maximum I²C clock frequency supported by the 24C00-I/SN?
The 24C00-I/SN supports up to 400 kHz I²C clock frequency when operated within its specified 4.5–5.5 V supply range and -40°C to +85°C temperature window. This Fast-mode capability is explicitly confirmed in Table 1-2 of DS20001178J and enables faster configuration loading compared to standard 100 kHz mode. The 24C00-I/SN does not support 1 MHz operation.
Does the 24C00-I/SN require an external pull-up resistor on the SDA and SCL lines?
Yes, the 24C00-I/SN requires external pull-up resistors on both SDA and SCL lines because it uses open-drain outputs. Microchip recommends 2 kΩ for 400 kHz operation and 10 kΩ for 100 kHz, connected to VCC. Failure to install these resistors will prevent proper I²C bus signaling and ACK generation.
How many times can the 24C00-I/SN be written before wear-out?
The 24C00-I/SN is rated for more than 1 million erase/write cycles per memory location, as stated in the Features section of DS20001178J. This endurance level is validated through characterization and supports multi-year field deployment in applications with infrequent updates, such as calibration storage or device serialization.
Is the 24C00-I/SN pin-compatible with other devices in the 24XX00 family?
Yes, the 24C00-I/SN shares identical pinout and package dimensions with 24AA00-I/SN and 24LC00-I/SN in SOIC-8, TSSOP, and PDIP packages. However, voltage ranges differ: 24C00 requires 4.5–5.5 V, while 24AA00 operates down to 1.8 V and 24LC00 down to 2.5 V. Swapping without verifying supply compliance may cause functional failure.
What happens if a write command is issued to the 24C00-I/SN while VCC is below specification?
The 24C00-I/SN includes an internal VCC threshold detector that disables the erase/write logic when VCC falls below 3.8 V (nominal). Below this level, the device will not acknowledge write commands and will ignore attempted programming - preventing corrupted data writes during power brownouts or unstable supply conditions.
