Product details
Overview
24LC00-I/SN from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-power, space-constrained embedded systems requiring nonvolatile storage of calibration data, device IDs, or manufacturing parameters. It operates from 2.5V to 5.5V, draws only 500 µA typical read current and 100 nA typical standby current, and supports 100 kHz/400 kHz clock rates in industrial temperature range (–40°C to +85°C).
For engineers reviewing the 24LC00-I/SN datasheet, 24LC00-I/SN pinout, 24LC00-I/SN application, or 24LC00-I/SN equivalent, this page delivers 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 24LC00-I/SN implements a true 2-wire I²C slave interface with Schmitt-trigger inputs and slope-controlled outputs to suppress ground bounce and noise. Its internal address pointer enables current-address, random, and sequential read modes, while self-timed erase/write cycles eliminate external timing dependencies.
It uses on-chip charge-pump voltage generation for EEPROM programming, includes VCC threshold detection (disables write below 2.5V), and relies on ACK polling-not fixed delay-to confirm write completion. No external components are required beyond standard I²C pull-ups (2 kΩ for 400 kHz, 10 kΩ for 100 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 words × 8 bits); sufficient for small configuration or identity storage without over-provisioning. |
| Supply voltage | 2.5V to 5.5V; compatible with 3.3V and 5V logic domains, excludes sub-2.5V operation unlike 24AA00. |
| Interface | I²C-compatible 2-wire bus; requires no additional protocol translation or level-shifting in standard microcontroller designs. |
| Write cycle time | Typical 3 ms per byte; enables rapid field updates while maintaining deterministic worst-case latency (≤4 ms). |
| Endurance | 1 million erase/write cycles; supports long-term logging or frequent recalibration in industrial equipment. |
| Data retention | Greater than 200 years at +85°C; ensures firmware ID or calibration data integrity across product lifecycle. |
| ESD protection | >4000 V HBM; reduces need for external transient suppression in board-level ESD-prone environments. |
Pinout & Package
24LC00-I/SN is supplied in an 8-pin SOIC (3.90 mm) package with industry-standard footprint and thermal profile. Pin 1 is marked by a beveled corner or notch; the package is Pb-free and RoHS compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SCL | Serial clock input; synchronizes all I²C transfers; must be pulled high externally; Schmitt-triggered for noise immunity. |
| 2 | SDA | Bidirectional open-drain data line; requires external pull-up; changes only during SCL low except for START/STOP conditions. |
| 3 | NC | No connect; electrically isolated; no routing or grounding required. |
| 4 | VSS | Ground reference; return path for all internal circuitry and I²C bus currents. |
| 5 | NC | No connect; electrically isolated; no routing or grounding required. |
| 6 | NC | No connect; electrically isolated; no routing or grounding required. |
| 7 | NC | No connect; electrically isolated; no routing or grounding required. |
| 8 | VCC | Positive supply input (2.5–5.5V); powers EEPROM array, control logic, and on-chip HV generator. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 2.5V VCC, enabling direct integration into 3.3V systems without level shifters or regulators. |
| Ultra-low standby current | 100 nA typical; minimizes battery drain in always-on or energy-harvesting applications. |
| I²C clock compatibility | Supports both 100 kHz (standard-mode) and 400 kHz (fast-mode) bus speeds-no firmware rework needed across platforms. |
| Noise-immune inputs | Schmitt-trigger + 50 mV hysteresis on SCL/SDA; rejects transients up to 50 ns, eliminating external RC filtering. |
| Self-timed write cycle | Internal timing eliminates need for software delays or external watchdog timers during EEPROM programming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA00-I/SN | Lower VCC min = 1.8V; identical pinout, memory size, and timing; same SOIC-8 package. | Required where 1.8V–3.3V systems dominate (e.g., wearables, IoT edge nodes); not suitable for 2.5V-only designs due to wider voltage tolerance. | Select 24AA00-I/SN only if supply can dip below 2.5V; otherwise 24LC00-I/SN offers tighter voltage spec and guaranteed 2.5V operation. |
| AT24C01C-SSHM-T | 1 Kbit (128 × 8) capacity; same 2.5–5.5V range, I²C interface, and SOIC-8 package; 1M endurance, but 10-year data retention spec (vs. >200 years). | Used when future scalability to larger EEPROM is anticipated; higher density adds margin for firmware expansion or extended logging. | Choose AT24C01C-SSHM-T if >128 bits are needed later; 24LC00-I/SN remains optimal for minimal footprint and ultra-long retention-critical roles. |
Compared with 24AA00-I/SN and AT24C01C-SSHM-T, the 24LC00-I/SN uniquely balances strict 2.5V minimum operation, ultra-low 100 nA standby, and 200+ year data retention-making it ideal for cost-sensitive, long-lifecycle industrial and medical devices where voltage margin and longevity outweigh density needs.

FAQ
What is the minimum operating voltage for 24LC00-I/SN?
The 24LC00-I/SN requires a minimum supply voltage of 2.5V, as specified in Microchip DS20001178J. Unlike the 24AA00 variant, it is not rated for operation below 2.5V-even at room temperature. Attempting to operate the 24LC00-I/SN below this threshold may result in failed writes or unpredictable I²C communication. Always verify VCC stability within 2.5V–5.5V during design validation.
Does 24LC00-I/SN support fast-mode I²C (400 kHz)?
Yes, the 24LC00-I/SN fully supports I²C fast-mode operation up to 400 kHz across its full industrial temperature range (–40°C to +85°C) and supply range (2.5V–5.5V). AC timing parameters-including THIGH, TLOW, and TSU:DAT-are explicitly characterized for 400 kHz in DS20001178J Table 1-2, confirming reliable interoperability with modern microcontrollers without bus speed derating.
How many write cycles can 24LC00-I/SN endure?
The 24LC00-I/SN is rated for more than 1 million erase/write cycles per memory location, as confirmed in the Features section of DS20001178J. This endurance is ensured through characterization-not 100% testing-and applies across the full industrial temperature range. For applications exceeding this count, Microchip's Total Endurance™ Model provides statistical lifetime estimation based on actual usage conditions.
Is 24LC00-I/SN pin-compatible with other 24XX00 family members?
Yes, the 24LC00-I/SN shares identical pinout and package dimensions with 24AA00-I/SN and 24C00-I/SN in SOIC-8, TSSOP, PDIP, and SOT-23 variants. All three devices use pins 1 (SCL), 2 (SDA), 4 (VSS), and 8 (VCC) identically; NC pins occupy the same positions. However, voltage ranges differ-so electrical compatibility must be verified per application before substitution.
What is the purpose of ACK polling with 24LC00-I/SN?
ACK polling is the recommended method to detect write completion in the 24LC00-I/SN, since the device halts I²C acknowledgments during its internal self-timed write cycle (up to 4 ms). By repeatedly issuing a Start + control byte (R/W = 0), the host determines readiness when an ACK is received-enabling maximum bus utilization without fixed delays. This behavior is documented in Section 7.0 of DS20001178J.
