Product details
Overview
24LC014T-I/MNY 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 rate and industrial temperature range (–40°C to +85°C). It features hardware write protection via WP pin, 16-byte page write buffer, and 1,000,000 erase/write cycles - deployed in embedded system configuration storage, sensor calibration data retention, and power-fail-safe parameter backup.
For engineers reviewing the 24LC014T-I/MNY datasheet, 24LC014T-I/MNY pinout, 24LC014T-I/MNY application, or 24LC014T-I/MNY equivalent, this page delivers verified electrical specs, package mapping to 8-lead TSSOP (MNY), I²C timing compliance, endurance validation, and real-world use-case implementation guidance - all grounded in DS21809G revision G.
Technical Context
The 24LC014T-I/MNY implements a two-wire I²C slave interface with fixed 7-bit address prefix '1010', three hardware address inputs (A0–A2), and dedicated Write-Protect (WP) control. Its internal architecture includes an on-chip page buffer supporting up to 16-byte writes, auto-erase logic, and self-timed 5 ms max write cycle.
It supports both byte and page write modes, current-address/random/sequential read operations, and acknowledge polling for bus efficiency. The device uses Schmitt-trigger inputs on SDA/SCL for noise immunity and requires external pull-up resistors (2 kΩ typical for 400 kHz operation).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Kbit (128 × 8-bit), single-block organization - enables simple address management without bank switching. |
| VCC Range | 2.5V to 5.5V - compatible with standard 3.3V and 5V logic systems; excludes sub-2.5V operation unlike 24AA014. |
| Max Clock Frequency | 400 kHz at VCC ≥ 2.5V - supports high-speed I²C mode for faster firmware updates or calibration writes. |
| Write Endurance | 1,000,000 erase/write cycles - ensures long-term reliability in field-updatable systems like smart meters or industrial controllers. |
| Data Retention | 200 years at 25°C - guarantees nonvolatile storage integrity across product lifecycle without refresh. |
| Standby Current | 1 µA typical at 5.5V - minimizes quiescent power draw in battery-backed or energy-harvesting applications. |
| Page Write Buffer | 16 bytes - reduces I²C transaction count by up to 16× versus byte-write, improving bus throughput and MCU overhead. |
Pinout & Package
24LC014T-I/MNY is packaged in an 8-lead TSSOP (MNY), measuring 3.0 mm × 4.4 mm × 1.2 mm, with gull-wing leads and RoHS-compliant matte tin finish. Pin 1 is laser-marked; lead pitch is 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Chip Address Input | LSB of 3-bit hardware slave address; tied to VSS or VCC to select one of eight devices on shared I²C bus. |
| A1 | Chip Address Input | Middle bit of slave address; enables multi-device addressing without software reconfiguration. |
| A2 | Chip Address Input | MSB of slave address; required for full 8-device support; not present in SOT-23 variant. |
| VSS | Ground Reference | Return path for all internal circuitry; must be low-impedance connection to system ground plane. |
| SDA | Serial Data I/O | Open-drain bidirectional line; requires external pull-up resistor (2 kΩ typical); carries address, data, and ACK/NACK. |
| SCL | Serial Clock Input | Master-generated clock signal; synchronizes all data transfers; Schmitt-trigger input improves noise margin. |
| WP | Write-Protect Control | Hardware lock: tied to VCC disables all writes while permitting reads - prevents accidental firmware corruption. |
| VCC | Power Supply | Primary supply rail (2.5V–5.5V); decoupling capacitor (0.1 µF ceramic) required within 10 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| I²C Bus Compatibility | Fully compliant with Philips I²C specification, including Start/Stop detection, ACK/NACK, and 7-bit addressing - interoperable with standard microcontroller I²C peripherals. |
| Hardware Write Protection | Dedicated WP pin enables unconditional read-only mode without firmware intervention - critical for bootloader or security-critical configuration registers. |
| Page Write Capability | 16-byte buffer allows burst writes within single I²C transaction - cuts bus overhead by >90% vs. sequential byte writes, reducing MCU active time. |
| Extended Temperature Range | Industrial grade (–40°C to +85°C) validated across full VCC range - suitable for automotive body control modules and outdoor industrial sensors. |
| Low-Power Operation | 1 µA standby current and 0.1 mA typical active current at 5.5V - extends battery life in portable diagnostic tools and wireless sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA014T-I/MNY | Wider VCC range (1.7V–5.5V); supports 100 kHz only below 2.5V - enables ultra-low-voltage operation in coin-cell-powered devices. | Preferred where sub-2.5V supply or battery voltage decay below 2.5V is expected (e.g., remote sensors). | Select when system VCC may dip below 2.5V; verify I²C pull-up resistor value matches lower-speed timing. |
| AT24C01D-SSHM-T | Same 1 Kbit size, 1.7V–5.5V range, and 400 kHz speed; different pinout (SOIC-8) and manufacturer-specific write-cycle algorithm. | Drop-in replacement in SOIC-8 layouts; requires layout review for TSSOP-to-SOIC footprint conversion. | Choose for second-source assurance in SOIC-based designs; confirm WP functionality matches Microchip's implementation. |
Compared with 24LC014T-I/MNY, 24AA014T-I/MNY offers broader supply flexibility but reduced speed below 2.5V, while AT24C01D-SSHM-T provides footprint compatibility in SOIC-8 but demands validation of write-protection behavior and endurance under mixed-voltage conditions.

FAQ
What is the maximum I²C clock frequency supported by the 24LC014T-I/MNY?
The 24LC014T-I/MNY supports up to 400 kHz I²C clock frequency when VCC is 2.5V or higher. Below 2.5V, maximum clock rate drops to 100 kHz per DS21809G-page 2. This dual-speed capability ensures compatibility with both legacy 100 kHz systems and modern high-throughput designs using the 24LC014T-I/MNY.
Does the 24LC014T-I/MNY include hardware write protection?
Yes, the 24LC014T-I/MNY features a dedicated Write-Protect (WP) pin. When tied to VCC, it disables all write operations to the entire memory array while allowing unrestricted reads - a hardware-level safeguard against accidental overwrites that cannot be overridden by software commands.
What package type does the 24LC014T-I/MNY use?
The 24LC014T-I/MNY uses an 8-lead TSSOP package (MNY suffix), with 0.65 mm lead pitch, 3.0 mm × 4.4 mm body dimensions, and RoHS-compliant matte tin plating. This surface-mount package supports automated assembly and offers better thermal performance than PDIP in space-constrained applications.
How many devices can share the same I²C bus with the 24LC014T-I/MNY?
Up to eight 24LC014T-I/MNY devices can operate on a single I²C bus using unique combinations of the A0, A1, and A2 address pins. Each device responds only to its assigned 3-bit chip address, enabling scalable memory expansion up to 8 Kbits without additional address decoding logic.
What is the write endurance rating of the 24LC014T-I/MNY?
The 24LC014T-I/MNY is rated for 1,000,000 erase/write cycles per memory location at 25°C and VCC = 5.5V. This endurance level is validated through characterization and ensures reliable operation in applications requiring frequent parameter updates, such as factory calibration or firmware patching - consistent across all units of the 24LC014T-I/MNY family.
