Product details
Overview
24AA00/S from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-voltage embedded storage of calibration data, device IDs, and manufacturing traceability information. It operates from 1.8 V to 5.5 V, 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 24AA00/S datasheet, 24AA00/S pinout, 24AA00/S application, or 24AA00/S equivalent, this page delivers verified electrical specs, validated SOT-23 pin mapping, confirmed I²C timing compliance, endurance and retention metrics, and real-world use cases in space-constrained consumer and industrial systems.
Technical Context
The 24AA00/S implements a true 2-wire I²C slave interface with Schmitt-trigger inputs and output slope control to suppress noise and eliminate ground bounce. Its internal address pointer enables current-address, random, and sequential read modes without external address latching.
It features self-timed erase/write cycles with 3 ms typical page write time, VCC threshold detection disabling writes below 1.5 V, and ACK polling support to maximize bus throughput during write completion detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 × 8), sufficient for small configuration or ID storage without over-provisioning |
| Supply voltage | 1.8 V to 5.5 V - enables direct interfacing with 1.8 V, 3.3 V, and 5 V microcontrollers |
| Interface | I²C-compatible 2-wire serial - eliminates need for parallel address/data buses and reduces PCB routing complexity |
| Write endurance | 1 million erase/write cycles - supports long-term field calibration updates in deployed devices |
| Data retention | 200 years at +85°C - ensures nonvolatile storage integrity across product lifecycle without refresh |
| Standby current | 100 nA typical - critical for battery-powered or energy-harvesting applications requiring ultra-low quiescent power |
| Operating frequency | 100 kHz / 400 kHz - compatible with standard and fast-mode I²C masters without protocol translation |
Pinout & Package
24AA00/S is supplied in a Pb-free, RoHS-compliant 5-lead SOT-23 package (Microchip drawing C04-028D), optimized for high-density PCB layouts and automated assembly. The exposed pad is not electrically connected and may be left floating or tied to VSS per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SCL | Serial clock input - synchronizes all I²C transactions; requires external pull-up resistor |
| 2 | VSS | Ground reference - must be connected to system common ground plane for stable operation |
| 3 | SDA | Bidirectional open-drain data line - shared with other I²C devices; requires external pull-up resistor |
| 4 | NC | No connect - internally unconnected; must remain unconnected on PCB |
| 5 | VCC | Power supply input - accepts 1.8 V to 5.5 V; decoupling capacitor recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 0.05 × VCC hysteresis - rejects noise spikes up to 50 ns, enabling reliable operation on noisy industrial buses |
| Output slope control | Controlled SDA fall time - prevents ground bounce that could corrupt adjacent digital signals |
| Factory programming option | Pre-programmed memory contents available - reduces post-manufacturing test and configuration steps |
| ESD protection | >4000 V HBM - withstands handling and board-level ESD events without latch-up or parametric shift |
| Temperature range | –40°C to +85°C industrial grade - qualified for use in automotive cabin modules, industrial sensors, and consumer appliances |
Applications
| Smart Sensor Calibration | IoT Device Identity Storage |
|---|---|
Use Scenario: Storing factory-calibrated sensor offset/gain coefficients in compact environmental sensors. IC Role / Device Role / Timing Role: Nonvolatile configuration storage accessed once at power-up via I²C by host MCU.

Use Value: Supports 1M write cycles - accommodates repeated reconfiguration during commissioning and maintenance without wear-out risk. |
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 | Requires minimum 2.5 V VCC; identical 128-bit capacity, SOT-23 package, and I²C timing | Not suitable for 1.8 V systems; otherwise drop-in in 3.3 V/5 V designs with same footprint | Select when operating above 2.5 V and legacy 24LC00 qualification is required |
| AT24C01C-SSHM-T | 1 Kbit (128 × 8) capacity; same 1.7–5.5 V range, 5-lead SOT-23, and I²C compatibility | Offers 8× more memory; higher write endurance (1M vs 1M) but no factory programming option | Choose when future firmware expansion or additional parameter storage is anticipated |
Compared with 24AA00/S, 24LC00-I/SN trades lower voltage capability for established qualification history, while AT24C01C-SSHM-T provides scalable memory headroom at identical package and interface compatibility - enabling design reuse without layout changes.

FAQ
What is the minimum operating voltage for the 24AA00/S?
The 24AA00/S operates down to 1.8 V, making it compatible with modern low-voltage microcontrollers and battery-powered systems. Below 1.5 V, its internal write logic is disabled by a VCC threshold detector to prevent incomplete or corrupted writes - a safeguard confirmed in DS20001178J Section 6.1.
Does the 24AA00/S support fast-mode I²C (400 kHz)?
Yes, the 24AA00/S supports both standard-mode (100 kHz) and fast-mode (400 kHz) I²C operation across its full 1.8 V–5.5 V supply range. AC timing parameters including THIGH, TLOW, and TSU:DAT are fully specified for 400 kHz at VCC ≥ 2.5 V per Table 1-2 in the official datasheet.
How many write cycles can the 24AA00/S endure?
The 24AA00/S guarantees 1 million erase/write cycles, validated through characterization (not 100% tested per Note 4, DS20001178J-page 3). This endurance rating ensures robust field reliability for applications requiring periodic updates such as sensor recalibration or firmware metadata logging.
Is the 24AA00/S pin-compatible with other 24XX00 variants in SOT-23?
Yes - the 24AA00/S shares identical 5-pin SOT-23 pinout (SCL, VSS, SDA, NC, VCC) with 24LC00-I/SN and 24C00-E/SN per Pin Function Table (DS20001178J-page 4). However, voltage and temperature ratings differ, so electrical compatibility must be verified per application conditions.
What is the data retention specification for the 24AA00/S?
The 24AA00/S provides greater than 200 years of data retention at +85°C ambient temperature, as specified in the Features section (DS20001178J-page 1). This applies to data written under recommended operating conditions and ensures long-term integrity without refresh in sealed or thermally managed enclosures.
