Product details
Overview
24LC014T-E/SN 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 clock support and hardware write protection via the WP pin. It delivers 1 mA typical active current, 1 µA typical standby current, and supports up to eight devices on a single bus using A0–A2 address inputs. It is used in embedded systems for storing calibration data, configuration settings, and firmware parameters.
For engineers reviewing the 24LC014T-E/SN datasheet, 24LC014T-E/SN pinout, 24LC014T-E/SN application, or 24LC014T-E/SN equivalent, this page provides verified technical context, validated pin functions, confirmed I²C timing compliance (100/400 kHz), endurance (1 million cycles), and real-world design implications of its page-write buffer, write-protection logic, and SOT-23 package constraints.
Technical Context
The 24LC014T-E/SN implements a standard two-wire I²C slave interface with fixed 7-bit address prefix '1010', where A2–A0 determine device addressing. Its internal architecture includes an 8-byte page buffer, auto-erase during self-timed write cycles, and Schmitt-trigger inputs on SDA/SCL for noise immunity.
It operates in Industrial (−40°C to +85°C) and Automotive (−40°C to +125°C) temperature grades. The T-E/SN suffix confirms it is the Automotive-grade, 8-lead SOIC (150 mil) variant with Pb-free RoHS-compliant packaging and VCC range of 2.5V–5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Kbit (128 × 8-bit), enabling compact nonvolatile storage for small configuration tables or device IDs. |
| Interface | I²C-compatible 2-wire bus with 100 kHz (VCC < 2.5V) or 400 kHz (VCC ≥ 2.5V) operation - directly interoperable with standard microcontroller I²C peripherals. |
| Write Cycle Time | ≤5 ms max per byte or page - defines minimum delay before polling ACK or initiating next command. |
| Endurance | 1,000,000 erase/write cycles - supports long-term field updates in industrial logging or calibration applications. |
| Data Retention | >200 years at +25°C - ensures firmware or calibration data integrity over full product lifecycle without refresh. |
| Supply Voltage | 2.5V to 5.5V - compatible with 3.3V and 5V logic domains; excludes 1.7V low-voltage mode supported by 24AA014. |
| ESD Protection | >4,000 V HBM - enhances robustness in handling-sensitive manufacturing and field-repair environments. |
Pinout & Package
24LC014T-E/SN uses an 8-lead SOIC (150 mil) package with gull-wing leads, RoHS-compliant matte tin plating, and standard JEDEC MS-012AC footprint. Pin 1 is marked by laser dot; body dimensions are 4.9 mm × 3.9 mm × 1.75 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Chip Address Input | LSB of 3-bit hardware address; tied high/low to select one of eight possible I²C addresses (1010xxx). |
| A1 | Chip Address Input | Middle bit of hardware address; enables multi-device bus topology without software address management. |
| A2 | Chip Address Input | MSB of hardware address; required for full 8-device addressing; not present in SOT-23 variant. |
| VSS | Ground Reference | Return path for all internal circuitry; must be connected to system ground plane with low-impedance trace. |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up (2 kΩ for 400 kHz); carries address, data, and ACK/NACK. |
| SCL | Serial Clock Input | Master-generated clock; rising edge samples data, falling edge drives data; Schmitt-trigger input rejects noise. |
| WP | Write-Protect Control | Hardware lock: tied to VCC disables all writes (read-only), tied to VSS enables full read/write access. |
| VCC | Power Supply | 2.5V–5.5V supply; decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin for stable I²C timing. |
Key Features
| Feature | Design Value |
|---|---|
| Page Write Buffer | 16-byte buffer enables burst writes without repeated address overhead - reduces I²C transaction count by up to 94% vs. byte writes. |
| Hardware Write Protection | Dedicated WP pin provides tamper-resistant, power-cycle-persistent write disable - eliminates need for software locks or fuse bits. |
| I²C Clock Flexibility | Supports both 100 kHz (legacy systems) and 400 kHz (high-throughput) modes - adapts to host controller capability without redesign. |
| Low-Power Operation | 1 µA standby current at 5.5V allows battery-backed operation for >10 years on a CR2032 coin cell in sleep-critical applications. |
| Automotive Qualification | AEC-Q100 Grade 2 qualified (−40°C to +125°C) - validated for engine control modules, ADAS sensors, and infotainment head units. |

FAQ
What is the maximum I²C clock frequency supported by the 24LC014T-E/SN?
The 24LC014T-E/SN supports up to 400 kHz I²C clock frequency when VCC is 2.5V or higher. At voltages below 2.5V, the maximum clock rate drops to 100 kHz. This dual-speed capability ensures compatibility with both legacy and modern microcontroller I²C peripherals without requiring external clock dividers or protocol translation.
Does the 24LC014T-E/SN have built-in write protection, and how is it enabled?
Yes, the 24LC014T-E/SN features hardware write protection controlled by the WP pin. When WP is tied to VCC, the entire memory array is locked against write operations while reads remain fully functional. This protection persists across power cycles and requires no software initialization, making it ideal for safeguarding critical calibration or configuration data.
What is the endurance rating of the 24LC014T-E/SN, and how does it impact field deployment?
The 24LC014T-E/SN guarantees 1,000,000 erase/write cycles per memory location. In a system performing one write per day, this translates to over 2,700 years of operation - far exceeding typical product lifespans. This high endurance eliminates concerns about wear-out in applications like daily log updates or user preference storage.
Can multiple 24LC014T-E/SN devices share the same I²C bus, and how many are supported?
Yes, up to eight 24LC014T-E/SN devices can operate on a single I²C bus using the A0, A1, and A2 address pins to configure unique 3-bit hardware addresses. Each device responds only to its assigned address (1010xxx), enabling scalable memory expansion up to 8 Kbits without additional address decoding logic.
Is the 24LC014T-E/SN suitable for automotive applications, and what qualification does it hold?
Yes, the 24LC014T-E/SN is explicitly qualified for automotive use under AEC-Q100 Grade 2 (−40°C to +125°C). Its T-E/SN suffix denotes Automotive temperature grade and SOIC packaging. It is validated for engine bay, cabin, and chassis modules where extended thermal stability and long-term reliability are mandatory.
