Product details
Overview
24LC00/P from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-power, space-constrained applications 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). Its 8-lead PDIP package enables through-hole prototyping and legacy board compatibility.
For engineers reviewing the 24LC00/P datasheet, 24LC00/P pinout, 24LC00/P application, or 24LC00/P equivalent, this page delivers verified electrical specs, validated I²C timing behavior, confirmed PDIP pin mapping, and real-world use cases - all grounded in Microchip's DS20001178J datasheet and official package documentation.
Technical Context
The 24LC00/P implements a slave-only I²C interface with Schmitt-trigger inputs and slope-controlled outputs to suppress noise and eliminate ground bounce. Its internal address counter supports current-address, random, and sequential read modes, while self-timed erase/write cycles eliminate external timing dependencies.
It features a 3 ms typical page write time, >1 million endurance cycles, and >200 years of data retention. The device includes VCC threshold detection that disables write logic below 2.5V nominal, ensuring reliable operation only within its specified supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 × 8), sufficient for small configuration or identification data without over-provisioning. |
| Supply voltage range | 2.5V to 5.5V - compatible with 3.3V and 5V systems but not 1.8V logic rails (distinguishes it from 24AA00). |
| I²C clock support | 100 kHz and 400 kHz - enables integration into both legacy and higher-speed I²C buses without protocol translation. |
| Write cycle time | Typical 3 ms - defines minimum interval between successive writes; supports ACK polling for deterministic timing control. |
| Endurance & retention | 1 million erase/write cycles and >200 years data retention - suitable for infrequent updates in long-lifecycle industrial deployments. |
| Operating temperature | –40°C to +85°C (Industrial grade) - validated for use in embedded controllers, sensors, and power supplies outside automotive extremes. |
| ESD protection | >4000 V HBM - provides robustness against handling and board-level electrostatic discharge during assembly and field service. |
Pinout & Package
24LC00/P is supplied in an 8-lead Plastic Dual In-Line Package (PDIP) with 300-mil body width, optimized for breadboarding, manual soldering, and legacy PCB layouts. Pin 1 is marked by a notch or dot on the package top surface.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - electrically isolated; must remain unconnected to avoid unintended coupling or latch-up. |
| 2 | NC | No connection - no internal bond wire; floating per datasheet; no pull-up/down required. |
| 3 | NC | No connection - unused pad; no routing or thermal tie needed in layout. |
| 4 | VSS | Ground reference - must be connected to system common ground plane with low-inductance path for stable I²C signaling. |
| 5 | SDA | Open-drain bidirectional data line - requires external pull-up resistor (10 kΩ @ 100 kHz, 2 kΩ @ 400 kHz) to VCC. |
| 6 | SCL | Open-drain clock input - driven by master only; same pull-up requirements as SDA for bus integrity. |
| 7 | NC | No connection - no internal function; leave unconnected and un-routed on PCB. |
| 8 | VCC | Positive supply - must be decoupled with 0.1 µF ceramic capacitor placed ≤5 mm from pin to minimize noise-induced I²C glitches. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | 0.05 × VCC hysteresis - rejects noise spikes up to 50 ns, eliminating need for external RC filtering on SDA/SCL lines. |
| Output slope control | Controlled rise/fall times - prevents ground bounce and EMI during bus transitions, critical for mixed-signal PCBs. |
| Self-timed write cycle | No external timing components required - simplifies firmware design and eliminates dependency on precise delay loops or timers. |
| ACK polling support | Enables non-blocking write completion detection - allows master to perform other tasks while waiting for EEPROM readiness. |
| Pb-free & RoHS compliant | Matte tin (Sn) lead finish - meets global environmental regulations and supports lead-free reflow profiles (J-STD-020). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA00/P | Lower VCC min (1.8V), identical pinout and memory size - but rated for same industrial temp range. | Better suited for battery-powered or ultra-low-voltage systems where 2.5V supply is unavailable. | Select 24AA00/P only if supply can drop below 2.5V; otherwise 24LC00/P offers tighter VCC tolerance margin at 3.3V/5V rails. |
| AT24C01A-PUM | 1 Kbit (128 × 8), same PDIP-8 package, 1.7–5.5V supply, but lacks factory programming option and has different write-cycle timing. | Higher density for future-proofing; however, larger memory may increase cost and layout footprint unnecessarily for 128-bit needs. | Choose AT24C01A-PUM only when additional capacity is required; for pure 128-bit use, 24LC00/P provides optimal cost/performance match. |
Compared with 24AA00/P and AT24C01A-PUM, the 24LC00/P delivers the most precise fit for 128-bit, 2.5–5.5V, industrial-grade EEPROM needs - avoiding over-specification while guaranteeing Microchip's qualification and long-term supply continuity.

FAQ
What is the minimum operating voltage for the 24LC00/P?
The 24LC00/P requires a minimum supply voltage of 2.5V, as specified in the Device Selection Table and DC Characteristics section of DS20001178J. Operation below this threshold disables internal write logic via VCC threshold detection, preventing corrupted writes. This distinguishes it from the 24AA00/P (1.8V min) and confirms its suitability for 3.3V and 5V systems only.
Does the 24LC00/P support 400 kHz I²C communication?
Yes, the 24LC00/P fully supports 400 kHz I²C clock frequency across its entire operating voltage range (2.5V–5.5V), as documented in Table 1-2 AC Characteristics. At 400 kHz, it requires a 2 kΩ pull-up resistor on SDA/SCL lines to meet rise-time specifications, enabling faster configuration reads in time-sensitive applications.
How many write cycles can the 24LC00/P endure?
The 24LC00/P is rated for more than 1 million erase/write cycles, as stated in the Features section and confirmed in Table 1-2 (Endurance = 1M cycles). This specification is ensured by characterization - not 100% tested - and supports long-term deployment in applications with infrequent updates, such as factory calibration storage.
What is the function of pins 1, 2, 3, and 7 on the 24LC00/P PDIP package?
Pins 1, 2, 3, and 7 of the 24LC00/P are designated NC (No Connect) per the Pin Function Table on DS20001178J-page 4. They have no internal bond wires or circuit connections and must remain unconnected in PCB layout and schematic design to prevent noise coupling or unintended parasitic paths.
Is the 24LC00/P RoHS compliant and lead-free?
Yes, the 24LC00/P is Pb-free and RoHS compliant, with a matte tin (Sn) lead finish as noted in the Features section and Packaging Information. The "P" suffix in the part number explicitly denotes the Pb-free PDIP variant, and marking includes the JEDEC Pb-free designator per Microchip's conversion program.
