Product details
Overview
24LC00T/SN from Microchip Technology Inc. is a 128-bit I²C-compatible serial EEPROM organized as 16 × 8, designed for low-power embedded 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 24LC00T/SN datasheet, 24LC00T/SN pinout, 24LC00T/SN application, or 24LC00T/SN equivalent, this page delivers verified electrical specs, package mapping, I²C timing compliance, endurance (1M cycles), and real-world use context - all confirmed against Microchip DS20001178J.
Technical Context
The 24LC00T/SN implements a slave-only I²C 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, while self-timed erase/write cycles require no external timing control.
It uses open-drain SDA/SCL pins with built-in hysteresis (≥0.05×VCC) and input filter spike suppression (≤50 ns), ensuring robust operation on noisy buses. The device includes VCC threshold detection that disables write logic below 2.5V nominal, preventing incomplete writes during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 × 8), sufficient for small nonvolatile configuration storage without over-provisioning. |
| Supply voltage | 2.5V to 5.5V - compatible with 3.3V and 5V systems; excludes 1.8V operation (reserved for 24AA00). |
| I²C speed | 100 kHz or 400 kHz - supports standard- and fast-mode I²C without external clock stretching. |
| Write cycle time | 3 ms typical - enables rapid parameter updates; full write completion confirmed via ACK polling. |
| Endurance & retention | 1 million erase/write cycles and >200 years data retention - validated for long-life industrial deployments. |
| Quiescent current | 100 nA typical standby current - critical for battery-backed or energy-harvesting applications. |
| ESD rating | 4 kV HBM - meets industrial-level ESD immunity requirements without external protection. |
Pinout & Package
24LC00T/SN is supplied in 8-pin SOIC (3.90 mm body width), per Microchip's official marking and packaging documentation. Pin functions are identical across SOIC, PDIP, TSSOP, DFN, and TDFN variants - only the 5-pin SOT-23 differs in pin count and layout.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SCL | Serial clock input - synchronizes all I²C transfers; requires external pull-up; Schmitt-triggered for noise immunity. |
| 2 | SDA | Bidirectional open-drain data line - used for address/data transfer and ACK/NACK signaling; requires 2–10 kΩ pull-up. |
| 3 | NC | No connect - internally unconnected; must be left floating or tied to GND/VCC per board design rules (no functional impact). |
| 4 | VSS | Ground reference - serves as return path for all internal circuitry and I/O leakage currents. |
| 5 | NC | No connect - same as Pin 3; not bonded or routed internally. |
| 6 | NC | No connect - same as Pin 3; no electrical function. |
| 7 | NC | No connect - same as Pin 3; unused in all 24LC00 variants including SOIC. |
| 8 | VCC | Power supply input - accepts 2.5V–5.5V; internal VCC detector prevents writes below 2.5V nominal. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage I²C interface | Operates down to 2.5V VCC - enables direct interfacing with 3.3V microcontrollers without level shifters. |
| Schmitt-trigger inputs | Hysteresis ≥0.05×VCC on SDA/SCL - rejects noise spikes up to 50 ns, eliminating need for external RC filtering. |
| Output slope control | Controlled SDA fall time (20+0.1×CB ns) - prevents ground bounce and signal integrity issues on shared bus lines. |
| Self-timed write cycle | No external timing components required - internal oscillator manages erase/write; status confirmed via ACK polling. |
| Pb-free & RoHS compliant | Meets EU RoHS Directive 2011/65/EU - suitable for commercial and industrial products requiring environmental compliance. |

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 | Supports 1.8V–5.5V operation; otherwise identical pinout, timing, and memory map. | Required where system VCC may dip below 2.5V (e.g., battery-powered wearables). | Select 24AA00T/SN only if sub-2.5V operation is mandatory; 24LC00T/SN offers better noise margin at 3.3V/5V. |
| AT24C01A-PU | 1-Kbit capacity (128 × 8), same 2.5V–5.5V range, but lacks Schmitt-trigger inputs and slope control. | Suitable for noise-clean environments; requires external RC filtering on SDA/SCL in electrically noisy chassis. | Choose AT24C01A-PU only when >128-bit capacity is needed; 24LC00T/SN provides superior bus robustness in compact footprint. |
Compared with 24AA00T/SN and AT24C01A-PU, the 24LC00T/SN delivers optimal balance of industrial-grade noise immunity, minimal quiescent power, and strict 2.5V minimum supply - making it the preferred choice for cost-sensitive, reliability-critical 128-bit storage in 3.3V/5V systems.

FAQ
What is the minimum operating voltage for 24LC00T/SN?
The 24LC00T/SN requires a minimum supply voltage of 2.5V, as specified in Microchip's DS20001178J datasheet. Unlike the 24AA00 variant, it does not support 1.8V operation. Attempting to operate below 2.5V will disable internal write logic via the VCC threshold detector, preventing unreliable programming.
Does 24LC00T/SN support both 100 kHz and 400 kHz I²C clock speeds?
Yes, the 24LC00T/SN fully supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C operation across its rated voltage range (2.5V–5.5V). AC timing parameters including THIGH, TLOW, and TSU:DAT are explicitly validated for both speeds in Table 1-2 of DS20001178J.
How many write cycles can 24LC00T/SN endure?
The 24LC00T/SN is rated for more than 1 million erase/write cycles, as confirmed in the Features section and Table 1-2 of DS20001178J. This endurance is ensured through characterization and applies across the full industrial temperature range (–40°C to +85°C).
What package type is used for 24LC00T/SN?
The 24LC00T/SN uses the 8-pin SOIC package with 3.90 mm body width (Microchip drawing C04-018D), as indicated by the "/SN" suffix per Microchip's packaging nomenclature in DS20001178J-page 12. Pin 1 is marked with a notch or dot; pins 3, 5, 6, and 7 are NC.
Is 24LC00T/SN RoHS compliant and lead-free?
Yes, the 24LC00T/SN is Pb-free and RoHS compliant, as stated in the Features section of DS20001178J. The "T" in the part number denotes tape-and-reel packaging, and the "SN" suffix confirms the SOIC package with matte tin (Sn) finish per JEDEC standards.
