Product details
Overview
24LC00T-I/MNY 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).
For engineers reviewing the 24LC00T-I/MNY datasheet, 24LC00T-I/MNY pinout, 24LC00T-I/MNY application, or 24LC00T-I/MNY equivalent, key selection considerations include its 5-pin SOT-23 package, I²C slave addressing (1010xxx0/1), Schmitt-trigger noise immunity, 3 ms typical page write time, and guaranteed 1 million erase/write cycles with >200-year data retention.
Technical Context
The 24LC00T-I/MNY implements a fixed 128-bit memory array organized as 16 words × 8 bits, accessed via a standard two-wire I²C bus where it functions exclusively as a slave device. Its internal address pointer auto-increments during sequential reads and resets on byte writes.
It features Schmitt-trigger inputs on SDA and SCL with 50 ns spike suppression and hysteresis ≥0.05×VCC (VCC ≥2.5 V), enabling robust operation on noisy PCBs. Write cycles are self-timed and internally managed, with VCC threshold detection disabling programming below 1.5 V to prevent corruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 × 8), sufficient for small configuration or identity storage without overdesigning footprint or cost. |
| Supply voltage | 2.5 V to 5.5 V - compatible with 3.3 V and 5 V systems; excludes 1.8 V operation (reserved for 24AA00). |
| I²C speed | 100 kHz / 400 kHz - supports standard-mode and fast-mode timing, validated across full VCC and temperature range. |
| Write cycle time | 3 ms typical - enables rapid parameter updates; no external delay required beyond ACK polling. |
| Endurance & retention | 1 million erase/write cycles and >200 years data retention - suitable for long-life industrial deployments with infrequent writes. |
| Quiescent current | 100 nA typical standby current - critical for battery-powered devices where leakage must be minimized. |
Pinout & Package
24LC00T-I/MNY is housed in a RoHS-compliant 5-pin SOT-23 package (1.90 mm × 2.80 mm × 1.30 mm), optimized for high-density PCB layouts. 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 - synchronous timing reference for all I²C transactions; requires external pull-up. |
| 2 | VSS | Ground reference - common return path for all internal circuitry and I/O signals. |
| 3 | SDA | Bidirectional open-drain data line - carries addresses, commands, and data; requires external pull-up resistor (2 kΩ for 400 kHz). |
| 4 | NC | No connect - internally unconnected; must remain unconnected on PCB to avoid unintended coupling. |
| 5 | VCC | Positive supply - powers EEPROM core and interface logic; bypass capacitor (0.1 µF) recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | ≥0.05×VCC hysteresis and 50 ns noise filtering - eliminates false triggering from EMI or ground bounce on SDA/SCL lines. |
| Output slope control | Controlled SDA fall time (20+0.1×CB ns) - prevents ground bounce-induced glitches during active drive transitions. |
| I²C compatibility | Fully compliant with Philips I²C-bus specification (100/400 kHz modes) - interoperable with standard microcontroller I²C peripherals. |
| ESD protection | 4 kV HBM - withstands handling and board-level electrostatic discharge without latch-up or parametric shift. |
| Factory programming | Available option - enables pre-loading of unique identifiers or calibration constants before shipment, reducing post-manufacture programming steps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA00T-I/MNY | Lower VCC min (1.8 V), higher standby current (1 µA max vs. 100 nA), same 128-bit capacity and SOT-23 package. | Better suited for ultra-low-voltage battery systems (e.g., coin-cell IoT sensors) where 1.8 V operation is mandatory. | Select when 1.8 V operation is required; accept higher quiescent current penalty for wider supply flexibility. |
| AT24C01C-SSHM-T | 1 Kbit (128 × 8) capacity, same 5-pin SOT-23, 1.7–5.5 V supply, but lacks factory programming option and has 3 µA max standby current. | Offers 8× more memory for extended configuration sets; less optimal for minimal-footprint, single-parameter storage. | Choose when additional memory headroom is needed for future feature expansion without changing board layout. |
Compared with 24LC00T-I/MNY, 24AA00T-I/MNY enables 1.8 V operation at the cost of higher standby draw, while AT24C01C-SSHM-T trades minimal footprint for 8× memory depth and no factory programming - making 24LC00T-I/MNY optimal for cost-sensitive, low-power, fixed-configuration use cases.

FAQ
What is the minimum operating voltage for 24LC00T-I/MNY?
The 24LC00T-I/MNY requires a minimum supply voltage of 2.5 V, as specified in its DC characteristics table. Unlike the 24AA00 variant, it is not rated for 1.8 V operation - attempting to power it below 2.5 V may result in unreliable writes or communication failures. Always verify VCC remains within 2.5 V to 5.5 V during all operating modes, including I²C transactions and internal write cycles.
Does 24LC00T-I/MNY support standard I²C addressing?
Yes, 24LC00T-I/MNY uses the standard 7-bit I²C slave address format: 1010xxx, where the three LSBs are "don't care" bits. The R/W bit determines operation mode (0 = write, 1 = read). This allows up to eight devices on the same bus without address conflicts, provided external pull-ups meet timing requirements for 100 kHz or 400 kHz operation.
How is write completion detected for 24LC00T-I/MNY?
Write completion is confirmed via acknowledge polling: after issuing a Stop condition to initiate an internal write, the host sends a repeated Start followed by the write address byte (R/W = 0). If the device is still busy, it will not acknowledge; once the 3 ms internal cycle finishes, it responds with ACK. This method avoids fixed delays and maximizes bus efficiency in time-critical systems using 24LC00T-I/MNY.
What is the function of Pin 4 (NC) on 24LC00T-I/MNY?
Pin 4 on the 5-pin SOT-23 package of 24LC00T-I/MNY is a no-connect terminal - it is not bonded internally and serves no electrical function. It must remain unconnected on the PCB layout; routing traces or applying solder paste to this pin risks shorting adjacent pins or introducing parasitic coupling that could affect SDA/SCL signal integrity.
Can 24LC00T-I/MNY be used in automotive applications?
No, 24LC00T-I/MNY is rated only for the industrial temperature range (–40°C to +85°C) and does not meet AEC-Q200 requirements for automotive qualification. For automotive body control or infotainment modules requiring extended temperature operation (–40°C to +125°C), Microchip's 24C00-E series or qualified alternatives like STMicroelectronics' M24C01-R should be selected instead of 24LC00T-I/MNY.
