Product details
Overview
24LC014T-I/MC from Microchip Technology Inc. is a 1 Kbit I²C-compatible serial EEPROM organized as 128 × 8-bit memory, operating from 2.5V to 5.5V with 400 kHz max clock frequency and hardware write protection via WP pin. It supports page writes up to 16 bytes, delivers ≤5 ms write cycle time, and offers 1 million erase/write cycles with >200 years data retention. It is used in embedded system configuration storage where low-voltage operation and bus scalability are required.
For engineers reviewing the 24LC014T-I/MC datasheet, 24LC014T-I/MC pinout, 24LC014T-I/MC application, or 24LC014T-I/MC equivalent, this page provides verified electrical specs, package mapping (8-lead TSSOP), validated I²C timing compliance (100/400 kHz), real-world endurance and retention metrics, and confirmed alternative parts for industrial temperature-grade EEPROM replacement.
Technical Context
The 24LC014T-I/MC implements a two-wire I²C interface with Schmitt-trigger inputs on SDA/SCL for noise immunity, supports standard and fast-mode clocking (100 kHz at VCC < 2.5V; 400 kHz at VCC ≥ 2.5V), and uses internal address pointer auto-increment for sequential reads across its 128-byte linear array. Its write-protection logic is hardwired via external WP pin state, not register-controlled.
It features a 16-byte page buffer enabling burst writes within a single physical page boundary, self-timed internal write cycle with auto-erase, and acknowledge polling support to detect write completion without fixed delay. The device requires no external high-voltage programming supply and operates fully within standard CMOS logic voltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1 Kbit (128 × 8-bit) - fits small firmware patches, calibration data, or device ID storage in space-constrained designs. |
| VCC range | 2.5V to 5.5V - compatible with 3.3V and 5V logic systems; excludes sub-2.5V operation unlike 24AA014 variant. |
| Max clock frequency | 400 kHz (at VCC ≥ 2.5V) - enables faster configuration loading than 100 kHz devices; requires ≤2 kΩ pull-up for reliable fast-mode timing. |
| Write endurance | 1,000,000 cycles - supports frequent recalibration or logging in industrial monitoring applications. |
| Data retention | >200 years at 25°C - ensures long-term reliability for unattended equipment without periodic refresh. |
| Standby current | 1 μA typical at 5.5V - minimizes quiescent power in battery-backed or energy-harvesting systems. |
| Write cycle time | 5 ms max - defines minimum interval between successive write commands; critical for real-time logging rate planning. |
Pinout & Package
24LC014T-I/MC is packaged in an 8-lead TSSOP (Thin Shrink Small Outline Package) with 0.65 mm lead pitch, body dimensions 3.0 mm × 4.4 mm × 1.2 mm, and Pb-free/RoHS-compliant finish. Pin 1 is marked by laser indentation per Microchip specification DS21809G-page 28.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Chip address input | LSB of 3-bit slave address; sets device address bit A0 when tied to VSS (0) or VCC (1); enables up to eight devices on one I²C bus. |
| A1 | Chip address input | Middle bit of 3-bit slave address; determines unique I²C address alongside A0 and A2; must be statically biased. |
| A2 | Chip address input | MSB of 3-bit slave address; completes 3-bit hardware-selectable address (1010xxxA0); allows multi-device topology. |
| VSS | Ground reference | Primary return path for all internal circuitry; must be connected to system ground plane with low impedance. |
| SDA | Serial data I/O | Open-drain bidirectional bus line; requires external pull-up resistor (2 kΩ for 400 kHz); carries address, data, and ACK/NACK. |
| SCL | Serial clock input | Master-generated clock signal; synchronizes all data transfers; Schmitt-trigger input ensures noise immunity on rising/falling edges. |
| WP | Write-protect control | Hardware-level write inhibit: tied to VCC blocks all writes (reads unaffected); tied to VSS enables full read/write access. |
| VCC | Power supply | Single 2.5–5.5V supply; powers EEPROM core, interface logic, and HV generator for write/erase operations. |
Key Features
| Feature | Design Value |
|---|---|
| I²C bus compatibility | Fully compliant with Philips I²C specification, supporting standard (100 kHz) and fast-mode (400 kHz) timing - eliminates need for custom protocol translation. |
| Page write buffer | 16-byte internal buffer enables efficient burst writes within a single 16-byte page - reduces I²C transaction overhead vs. byte-by-byte writes. |
| Hardware write protection | Dedicated WP pin provides tamper-resistant, non-volatile write disable - prevents accidental overwrites during power transitions or firmware faults. |
| Extended temperature range | Industrial grade (-40°C to +85°C) - qualified for deployment in factory automation, HVAC controls, and outdoor metering without derating. |
| Low-power standby | 1 μA typical ICCS at 5.5V - enables always-on configuration storage in battery-powered edge nodes with multi-year shelf life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC014-I/P | Same electrical specs and memory map, but in 8-lead PDIP package (longer lead form, through-hole mounting). | Used in prototyping, legacy board upgrades, or applications requiring manual soldering or socket-based field replacement. | Select when mechanical fit, serviceability, or hand-soldering is prioritized over board area and reflow compatibility. |
| AT24C01D-SSHM-T | 1 Kbit I²C EEPROM from Microchip (acquired Atmel); identical 2.5–5.5V range, 400 kHz, 1M endurance, but different pinout (WP on pin 7 vs. 24LC014T-I/MC pin 7) and marking. | Drop-in replacement only if PCB layout accommodates alternate pin assignment; same industrial temp grade and RoHS compliance. | Choose when sourcing continuity is needed and board revision permits minor layout adjustment for pin mapping. |
Compared with 24LC014T-I/MC, the 24LC014-I/P offers identical functionality in through-hole format for ease of testing and repair, while AT24C01D-SSHM-T provides second-source availability with matching performance but requires pinout verification before PCB integration.

FAQ
What is the operating voltage range for the 24LC014T-I/MC?
The 24LC014T-I/MC operates from 2.5V to 5.5V. Unlike the 24AA014 variant, it does not support operation below 2.5V. This range ensures compatibility with both 3.3V and 5V logic systems while maintaining specified timing, endurance, and data retention performance across the full industrial temperature range (-40°C to +85°C).
Does the 24LC014T-I/MC support fast-mode I²C communication?
Yes, the 24LC014T-I/MC supports I²C fast-mode operation at up to 400 kHz when VCC is 2.5V or higher. At voltages below 2.5V, maximum clock frequency is limited to 100 kHz. Fast-mode capability enables faster configuration loading and reduces bus occupancy time in systems with multiple I²C peripherals.
How many devices can share the same I²C bus with the 24LC014T-I/MC?
Up to eight 24LC014T-I/MC devices can operate on the same I²C bus using unique combinations of the A0, A1, and A2 address pins. Each device is assigned a distinct 3-bit hardware address, allowing contiguous 8 Kbit expansion when software maps chip select bits to higher address bits (A8–A10).
What is the purpose of the WP pin on the 24LC014T-I/MC?
The WP (Write-Protect) pin on the 24LC014T-I/MC provides hardware-level write inhibition. When tied to VCC, all write operations-including byte and page writes-are blocked while read operations remain fully functional. This prevents accidental or malicious overwrites of critical configuration data during power-up, reset, or firmware updates.
Is the 24LC014T-I/MC pin-compatible with other Microchip 1 Kbit EEPROMs?
The 24LC014T-I/MC in TSSOP package shares identical pinout with other 24LC014 variants (e.g., 24LC014-I/SN, 24LC014-I/MS) but is not pin-compatible with Atmel AT24C01D or ST M24C01-R due to differing WP and NC pin assignments. Always verify pin function tables before substitution, especially for WP and address pin locations.
