Product details
Overview
24LC014-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 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 - used for configuration storage in embedded controllers and sensor calibration data retention.
For engineers reviewing the 24LC014-I/MC datasheet, 24LC014-I/MC pinout, 24LC014-I/MC application, or 24LC014-I/MC equivalent, key selection criteria include VCC range compatibility (2.5–5.5V), I²C bus timing at 400 kHz, WP-enabled hardware lock, 8-lead SOIC package footprint, and endurance under industrial thermal stress.
Technical Context
The 24LC014-I/MC implements a two-wire I²C interface with slave addressing using A0–A2 pins, supporting up to eight devices on one bus. Its internal address pointer enables sequential, random, and current-address read modes, while the 16-byte page buffer optimizes burst writes without host-side buffering.
Write protection is controlled solely by the WP pin state (VSS = enabled, VCC = disabled); no software lock mechanism exists. The device uses self-timed internal write cycles (≤5 ms) with acknowledge polling support, and Schmitt-trigger inputs on SDA/SCL ensure noise immunity across its full operating voltage and temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1 Kbit (128 × 8-bit), single-block organization - simplifies address management and eliminates bank switching logic. |
| Interface | I²C-compatible 2-wire bus - requires only SDA and SCL lines plus pull-ups; supports standard (100 kHz) and fast (400 kHz) modes. |
| VCC range | 2.5V to 5.5V - compatible with 3.3V and 5V systems; excludes sub-2.5V operation unlike 24AA014 variant. |
| Write endurance | 1,000,000 cycles - ensures long-term reliability in firmware update or logging applications with frequent rewrites. |
| Data retention | 200 years at +85°C - validated for industrial environments where nonvolatile storage must survive decades of thermal stress. |
| Package | 8-lead SOIC (MC suffix) - industry-standard 150-mil wide-body footprint, compatible with automated PCB assembly and legacy socket designs. |
| Temp range | Industrial: –40°C to +85°C - qualified per AEC-Q100 Class 2 for extended reliability in control modules and instrumentation. |
Pinout & Package
24LC014-I/MC is supplied in an 8-lead SOIC (150 mil) package with gull-wing leads, RoHS-compliant matte tin plating, and standard JEDEC MS-012AC outline. Pin 1 is marked by laser indentation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Chip address input | LSB of 3-bit slave address; hardwired to VSS or VCC to select one of eight possible I²C addresses (1010xxx0/1). |
| A1 | Chip address input | Middle bit of slave address; determines device uniqueness on shared I²C bus alongside A0 and A2. |
| A2 | Chip address input | MSB of slave address; enables up to eight 24LC014-I/MC devices on same bus without address conflict. |
| VSS | Ground reference | Primary 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 (2 kΩ for 400 kHz); carries address, command, and data bytes. |
| SCL | Serial clock input | Master-generated clock signal; synchronizes all data transfers; Schmitt-trigger input ensures noise immunity. |
| WP | Hardware write-protect | Active-high enable: tied to VCC disables all writes (read-only mode); tied to VSS enables full read/write access. |
| VCC | Power supply | 2.5V–5.5V DC input; powers EEPROM core, interface logic, and HV generator for write/erase operations. |
Key Features
| Feature | Design Value |
|---|---|
| Page write buffer | 16-byte buffer enables efficient burst writes without host intervention - reduces I²C transaction overhead by 87% vs. byte-write mode. |
| Hardware write protection | Dedicated WP pin provides tamper-resistant, power-cycle persistent lock - eliminates risk of accidental firmware corruption during field updates. |
| Low-power operation | 1 μA typical standby current at 5.5V - extends battery life in always-on IoT edge nodes and portable diagnostic tools. |
| I²C clock flexibility | Supports 100 kHz (full VCC range) and 400 kHz (VCC ≥ 2.5V) - allows design reuse across cost-sensitive and performance-critical platforms. |
| ESD robustness | 4,000V HBM rating - withstands handling and board-level ESD events without latch-up or parameter shift in industrial assembly environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC014T-I/MNY | Same electrical specs and pinout; tape-and-reel packaging (MNY) vs. tube (MC); identical SOIC-8 footprint. | No functional difference; selected for automated SMT production requiring reel-fed placement. | Choose 24LC014T-I/MNY for high-volume manufacturing; otherwise 24LC014-I/MC is optimal for prototyping and low-volume builds. |
| AT24C01D-SSHM-T | 1 Kbit I²C EEPROM, 1.7–5.5V VCC, 400 kHz, SOIC-8; lacks dedicated WP pin - write protection implemented via software address locking. | Requires firmware-level security implementation; not suitable where hardware-enforced lock is mandated (e.g., medical audit trails). | Select AT24C01D-SSHM-T only when VCC < 2.5V operation is needed; otherwise 24LC014-I/MC provides superior hardware write lock assurance. |
Compared with 24LC014T-I/MNY, the 24LC014-I/MC offers identical functionality in tube packaging for flexible sampling and small-batch use; versus AT24C01D-SSHM-T, it delivers deterministic hardware write protection critical for safety-critical configuration storage.

FAQ
What is the minimum VCC required for reliable operation of the 24LC014-I/MC?
The 24LC014-I/MC requires a minimum VCC of 2.5V for guaranteed operation across its full industrial temperature range. Unlike the 24AA014 variant, it is not rated below 2.5V - attempting operation at 1.8V may result in incomplete writes or read failures. Always verify supply stability within this window during power-rail validation for 24LC014-I/MC.
Does the 24LC014-I/MC support 400 kHz I²C communication at all VCC levels?
Yes, the 24LC014-I/MC supports 400 kHz I²C clocking at any VCC from 2.5V to 5.5V. This is confirmed in the Device Selection Table and AC Characteristics section of DS21809G, where FCLK max is specified as 400 kHz for VCC ≥ 2.5V. No derating is required - 24LC014-I/MC maintains full timing compliance across its entire supply range.
How does hardware write protection work on the 24LC014-I/MC?
The 24LC014-I/MC uses a dedicated WP pin: when tied to VCC, all write operations (byte and page) are inhibited while reads remain fully functional; when tied to VSS, full read/write access is enabled. This is a physical gate-level lock - no software command can override it. The WP pin has no internal pull-up/down, so external biasing is mandatory for deterministic behavior in 24LC014-I/MC designs.
Can multiple 24LC014-I/MC devices share the same I²C bus?
Yes, up to eight 24LC014-I/MC devices can coexist on one I²C bus using unique combinations of A0, A1, and A2 pin states. Each device responds only to its assigned 7-bit slave address (1010xxx), enabling contiguous 8 Kbit expansion. Address pins must be statically tied to VSS or VCC - dynamic control is unsupported and may cause bus contention in 24LC014-I/MC configurations.
What is the maximum write cycle time for the 24LC014-I/MC?
The maximum write cycle time for the 24LC014-I/MC is 5 ms for both byte and page writes, as specified in Table 1-2 (Param. No. 17, TWC). This includes internal auto-erase and programming; the device does not respond to I²C commands during this period. Acknowledge polling must be used to detect completion - no timeout shorter than 5 ms is safe for 24LC014-I/MC firmware implementations.
