Product details
Overview
24FC02-E/MS from Microchip Technology Inc. is a 2-Kbit I²C-compatible serial EEPROM organized as 256 × 8-bit memory with hardware write-protection, 1 MHz clock support (down to 1.7V), and extended temperature operation from –40°C to +125°C in an 8-lead MSOP package. It delivers ultra-low standby current (3 µA at E-temp), 5 ms max page write time, and >1 million erase/write cycles - used for secure configuration storage in automotive body control modules.
For engineers reviewing the 24FC02-E/MS datasheet, 24FC02-E/MS pinout, 24FC02-E/MS application, or 24FC02-E/MS equivalent, key selection criteria include its 1.7V–5.5V supply range, Schmitt-triggered I²C inputs for noise immunity, 8-byte page buffer, factory-programmable capability, and AEC-Q100 qualification for automotive use.
Technical Context
The 24FC02-E/MS implements a two-wire I²C interface with fixed 7-bit device address (1010xxx) and R/W bit control, supporting standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes depending on VCC. Its internal architecture includes a page latch buffer, HV generator for EEPROM programming, and dedicated memory control logic that manages self-timed erase/write cycles without external timing components.
It uses open-drain SDA/SCL with internal Schmitt triggers and slope control to suppress ground bounce and noise spikes. The WP pin provides hardware-level write protection across the full 256-byte array, and the device supports acknowledge polling to detect write completion - enabling efficient bus utilization in real-time embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Kbit (256 × 8-bit), sufficient for firmware revision IDs, calibration data, or security keys in compact MCU systems. |
| Interface | I²C-compatible two-wire serial bus, compatible with standard, fast, and fast-plus modes up to 1 MHz at 1.7V–5.5V. |
| Write Cycle Time | ≤5 ms maximum (byte or page), enabling rapid nonvolatile updates without blocking host processor execution. |
| Endurance | 1,000,000 erase/write cycles, supporting long-term field deployment in industrial logging or automotive diagnostics. |
| Data Retention | 200+ years at 25°C, ensuring persistent storage integrity across product lifecycles without refresh. |
| Operating Temp | –40°C to +125°C (Extended grade), validated for under-hood automotive and industrial edge sensor applications. |
| Supply Voltage | 1.7V to 5.5V, allowing direct interfacing with low-voltage MCUs (e.g., 1.8V logic) without level-shifting circuitry. |
Pinout & Package
24FC02-E/MS is housed in an 8-lead MSOP (Micro Small Outline Package) with 0.65 mm pitch, 3.0 mm × 3.0 mm body, and wettable flanks for automated optical inspection. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Accepts 1.7V–5.5V; powers internal charge pump and logic; decoupling capacitor required near pin. |
| WP | Hardware write-protect input | Tie to VSS for full read/write access; tie to VCC to lock entire 256-byte array against accidental writes. |
| SCL | Serial clock input | Open-drain, Schmitt-triggered; synchronizes all I²C transfers; requires external pull-up resistor (2 kΩ typical at 1 MHz). |
| SDA | Serial data I/O | Bidirectional open-drain line; transmits addresses, data, and ACK/NACK; shares pull-up with SCL in most designs. |
| VSS | Ground reference | System ground return path; must be low-impedance and co-located with VCC decoupling. |
| A0, A1, A2 | Address select inputs | No internal connection; may be left floating or tied to VSS/VCC without functional impact. |
Key Features
| Feature | Design Value |
|---|---|
| Fast-plus I²C support | 1 MHz clock rate at 1.7V–5.5V enables high-throughput configuration updates in time-critical automotive ECUs. |
| Schmitt-trigger inputs | Input hysteresis ≥0.05×VCC suppresses bus noise, eliminating false Start/Stop detection in electrically noisy environments. |
| Page write buffer | 8-byte buffer allows burst writes within one I²C transaction, reducing protocol overhead and improving effective write speed. |
| Hardware write protection | Single-pin (WP) global lock prevents firmware corruption during power transients or software faults without firmware intervention. |
| AEC-Q100 qualified | Qualified to Grade 1 (–40°C to +125°C), meeting automotive reliability requirements for permanent installation in vehicle subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA02-I/MS | Max clock 400 kHz (not 1 MHz); operates down to 1.7V but lacks fast-plus mode; same 8-lead MSOP package. | Lower bandwidth limits use in high-speed logging or real-time calibration update loops. | Select when system clock is capped at 400 kHz and extended temp range is not required. |
| 24LC02B-I/MS | Min VCC = 2.5V; no 1.7V operation; rated only to +85°C (I-temp), not +125°C (E-temp). | Unsuitable for automotive under-hood or industrial high-temp deployments where ambient exceeds 85°C. | Choose only for cost-sensitive consumer applications with stable 2.5V+ supplies and benign thermal environments. |
Compared with 24AA02-I/MS and 24LC02B-I/MS, the 24FC02-E/MS uniquely combines 1 MHz I²C, 1.7V operation, and extended temperature range - making it the only option among the three qualified for AEC-Q100 automotive systems requiring both speed and thermal robustness.

FAQ
What is the minimum operating voltage for the 24FC02-E/MS?
The 24FC02-E/MS operates down to 1.7V across its full temperature range (–40°C to +125°C). This enables direct integration with 1.8V logic families and battery-powered systems experiencing brownout conditions, unlike the 24LC02B which requires ≥2.5V. The 24FC02-E/MS maintains full 1 MHz I²C functionality even at 1.7V.
Does the 24FC02-E/MS support page write operations, and what is the buffer size?
Yes, the 24FC02-E/MS supports page write operations with an 8-byte page buffer. This allows up to eight sequential bytes to be written in a single I²C transaction, significantly reducing bus overhead compared to byte-wise writes. Page boundaries align every 8 bytes (addresses 00–07, 08–0F, etc.), and crossing boundaries causes wraparound within the same page.
How does hardware write protection work on the 24FC02-E/MS?
The WP pin on the 24FC02-E/MS provides hardware-level write protection: when tied to VCC, the entire 256-byte memory array is locked against write and erase operations while reads remain fully functional. When tied to VSS (or left floating), normal read/write access is enabled. This eliminates reliance on software locks and prevents corruption during power glitches.
Is the 24FC02-E/MS AEC-Q100 qualified, and what grade does it meet?
Yes, the 24FC02-E/MS is AEC-Q100 qualified to Grade 1, covering the extended temperature range of –40°C to +125°C. This qualification includes stress testing for accelerated environmental, thermal, and reliability performance - confirming suitability for permanent automotive installation in engine compartments, body control modules, and ADAS subsystems.
What packages are available for the 24FC02-E/MS, and is the MSOP variant lead-free?
The 24FC02-E/MS is offered in 8-lead MSOP (as indicated by the "/MS" suffix), along with PDIP, SOIC, TSSOP, and UDFN variants. The MSOP package is RoHS-compliant and features matte tin (Sn) lead finish per JEDEC standards. Its 0.65 mm pitch and wettable flanks support automated optical inspection and reliable reflow soldering in high-volume manufacturing.
