Product details
Overview
24LC02BT-E/MNY from Microchip Technology Inc. is a 2-Kbit I²C-compatible serial EEPROM organized as 256 × 8-bit memory with hardware write-protection, 8-byte page buffer, and operation down to 2.5V. It supports 400 kHz clock frequency, delivers ≤1 mA read current and ≤5 µA standby current (E-temp), and is qualified for extended temperature range (–40°C to +125°C) in automotive and industrial control applications.
For engineers reviewing the 24LC02BT-E/MNY datasheet, 24LC02BT-E/MNY pinout, 24LC02BT-E/MNY application, or 24LC02BT-E/MNY equivalent, key selection criteria include its E-temp rating, 2.5V minimum VCC, hardware WP pin functionality, 5 ms max write cycle time, and compatibility with I²C bus timing at 400 kHz under extended temperature conditions.
Technical Context
The 24LC02BT-E/MNY implements a two-wire I²C interface with Schmitt-trigger inputs and slope-controlled outputs to suppress noise and eliminate ground bounce. Its internal address pointer enables current-address, random, and sequential read modes, while the 8-byte page buffer allows efficient multi-byte writes within a single physical page boundary.
Write protection is implemented via the dedicated WP pin: tied to VSS for full read/write access, or to VCC to inhibit all write operations across the entire 00h–FFh memory array. Acknowledge polling is supported to detect write-cycle completion without fixed delay timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Kbit (256 × 8-bit), sufficient for calibration data, device IDs, or configuration registers in space-constrained systems |
| VCC Range | 2.5V to 5.5V - supports direct connection to 3.3V or 5V rails without level shifting |
| Max Clock Frequency | 400 kHz - compatible with standard-mode I²C controllers; not rated for 1 MHz (unlike 24FC02) |
| Page Write Buffer | 8 bytes - enables burst writes without host-side timing overhead, constrained by 256-byte address space |
| Write Cycle Time | 5 ms maximum - defines minimum inter-write interval; self-timed erase/write eliminates need for external timing control |
| Endurance & Retention | 1 million erase/write cycles and >200 years data retention - validated for long-life embedded deployments |
| Temperature Range | –40°C to +125°C (Extended grade) - certified for under-hood automotive and high-ambient industrial environments |
Pinout & Package
24LC02BT-E/MNY is supplied in an 8-lead UDFN package (2 mm × 3 mm, wettable flanks), with pin 1 marked by a dot. The package supports automated optical inspection (AOI) and provides enhanced solder joint reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Address Input | No internal connection; may be left floating or tied to VSS/VCC without affecting operation |
| A1 | Address Input | No internal connection; unused per device architecture |
| A2 | Address Input | No internal connection; no impact on I²C addressing (fixed 1010xxxR/W client address) |
| VSS | Ground | Reference return path for all signals and power; must be low-impedance for stable I²C signaling |
| SDA | Serial Data I/O | Open-drain bidirectional bus line requiring external pull-up resistor (2 kΩ typical for 400 kHz) |
| SCL | Serial Clock Input | Input-only clock line synchronized to host controller; determines maximum I²C throughput |
| WP | Write-Protect Input | Hardware-enforced lock: VCC disables all writes; VSS enables full read/write access |
| VCC | Power Supply | Primary supply rail (2.5–5.5V); powers EEPROM core and I/O buffers |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.05×VCC hysteresis on SDA/SCL, enabling robust operation on noisy PCBs or long traces |
| Output slope control | Controls rise/fall times to prevent ground bounce during switching, critical for mixed-signal system integrity |
| Hardware write-protect | Dedicated WP pin allows irreversible firmware-level lock of memory contents against accidental overwrite |
| ESD protection >4 kV | Meets IEC 61000-4-2 Level 3 for handling and board-level surge immunity |
| AEC-Q100 qualification | Validated for automotive Grade 1 (–40°C to +125°C), supporting deployment in engine control, ADAS, and body electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC02B-I/MNY | Same die, Industrial temp range (–40°C to +85°C); identical pinout, timing, and electrical specs except higher standby current (1 µA vs. 5 µA) at E-temp | Not qualified for under-hood or high-ambient industrial use; suitable only where ambient stays below 85°C | Select when cost sensitivity outweighs extended temperature requirement and system thermal margin is assured |
| AT24C02C-SSHM-T | 2-Kbit I²C EEPROM from Microchip (acquired Atmel); supports 1.7–5.5V VCC, 1 MHz clock, and 1.8V min operation - broader voltage range but different marking and packaging | Lacks AEC-Q100 qualification; not validated for automotive under-hood deployment | Choose for battery-powered or low-voltage designs needing 1.7V operation, but verify qualification status for safety-critical roles |
Compared with 24LC02BT-E/MNY, the 24LC02B-I/MNY offers lower standby current at 85°C but lacks extended temperature validation, while the AT24C02C-SSHM-T extends voltage flexibility and speed at the expense of automotive qualification - making 24LC02BT-E/MNY the sole choice for AEC-Q100-compliant E-temp deployments.

FAQ
What is the operating voltage range for the 24LC02BT-E/MNY?
The 24LC02BT-E/MNY operates from 2.5V to 5.5V. This VCC range is strictly defined for Extended temperature (–40°C to +125°C) operation; operation below 2.5V is not specified or guaranteed for this variant. Unlike the 24AA02 or 24FC02, the 24LC02BT-E/MNY does not support 1.7V operation.
Does the 24LC02BT-E/MNY support 1 MHz I²C clock frequency?
No, the 24LC02BT-E/MNY is rated for up to 400 kHz I²C clock frequency under its specified 2.5V–5.5V VCC and –40°C to +125°C conditions. The 1 MHz capability is exclusive to the 24FC02 variant; using 1 MHz with the 24LC02BT-E/MNY violates AC timing specifications and may result in communication failure.
How is write protection implemented on the 24LC02BT-E/MNY?
Write protection on the 24LC02BT-E/MNY is controlled by the dedicated WP pin: tying WP to VCC disables all write operations (byte and page) across the full 256-byte memory array, while tying WP to VSS enables full read/write access. No software command or register setting overrides this hardware lock.
What package type is used for the 24LC02BT-E/MNY?
The 24LC02BT-E/MNY is packaged in an 8-lead UDFN (2 mm × 3 mm) with wettable flanks, designated by the "MNY" suffix. This package supports automated optical inspection and improves solder joint reliability in high-reliability applications such as automotive and industrial systems.
Is the 24LC02BT-E/MNY AEC-Q100 qualified?
Yes, the 24LC02BT-E/MNY is AEC-Q100 qualified for Grade 1 (–40°C to +125°C), confirming its suitability for automotive applications including body electronics, infotainment, and ADAS subsystems where extended temperature performance and reliability are mandatory.
