Product details
Overview
24FC02T-E/MUY 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), 5 ms max page write time, and extended temperature operation from –40°C to +125°C. It serves as nonvolatile configuration storage in automotive body controllers, industrial sensor nodes, and embedded power management units.
For engineers reviewing the 24FC02T-E/MUY datasheet, 24FC02T-E/MUY pinout, 24FC02T-E/MUY application, or 24FC02T-E/MUY equivalent, key selection criteria include its 1.7V–5.5V supply range, 8-byte page buffer, Schmitt-triggered I²C inputs, ESD protection >4 kV, and AEC-Q100 qualification for automotive use.
Technical Context
The 24FC02T-E/MUY implements a two-wire I²C interface with fixed 7-bit client address (1010xxx) and R/W bit control, supporting byte and page write modes. Its internal Address Pointer auto-increments during sequential reads and resets on each new word address command.
It uses an on-chip HV generator for EEPROM programming, integrates slope-controlled outputs to suppress ground bounce, and employs Schmitt-trigger inputs with 50 ns spike filtering and 0.05 VCC hysteresis for robust noise immunity on noisy buses.
Key Specifications

| ESD Protection | >4,000 V HBM - reduces need for external transient suppression in cost-sensitive PCB layouts |
Pinout & Package
24FC02T-E/MUY is packaged in an 8-lead UDFN (Q4B) with wettable flanks, measuring 2 mm × 3 mm × 0.55 mm, optimized for automated optical inspection (AOI) and high-density PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS | Ground reference | Must be connected to system GND; exposed pad may be tied to VSS for thermal and EMI performance |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up (2 kΩ typical for 1 MHz); carries addresses, data, and ACK/NACK |
| SCL | Serial Clock input | Host-generated clock synchronizing all transfers; Schmitt-triggered with 50 ns noise filtering |
| WP | Hardware Write-Protect | Tie to VCC to lock entire 256-byte array; tie to VSS to enable full read/write access |
| VCC | Power supply | Accepts 1.7V–5.5V; supplies internal charge pump for EEPROM programming |
| A0–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 2× faster writes vs. 400 kHz devices, reducing boot-time configuration latency |
| Page write buffer | 8-byte buffer allows burst writes within one page boundary (00–07, 08–0F, etc.), minimizing I²C transaction overhead |
| Hardware write-protection | Dedicated WP pin provides tamper-resistant locking of critical parameters without software intervention or fuse blowing |
| Low-power operation | 1 µA max standby current at +125°C extends battery life in always-on sensor modules and telematics units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA02T-I/MS | Max clock 400 kHz; 1.7V–5.5V supply; Industrial temp only (–40°C to +85°C) | Lacks AEC-Q100 qualification and 125°C capability; lower write speed limits throughput in high-frequency polling systems | Select when automotive qualification and 1 MHz timing are unnecessary and cost is primary constraint |
| AT24C02D-SSHM-T | 1 MHz I²C; 1.7V–5.5V; Industrial temp; no AEC-Q100; different pinout (SOIC-8) | Not automotive-qualified; SOIC package increases board area vs. UDFN; lacks wettable flanks for AOI | Choose for legacy SOIC footprints where rework tolerance outweighs density and automotive compliance needs |
Compared with 24FC02T-E/MUY, the 24AA02T-I/MS offers lower cost but sacrifices automotive qualification and write speed, while the AT24C02D-SSHM-T matches speed but lacks AEC-Q100 and compact UDFN packaging - making 24FC02T-E/MUY optimal for space-constrained, safety-critical automotive and industrial designs.

FAQ
What is the maximum I²C clock frequency supported by the 24FC02T-E/MUY?
The 24FC02T-E/MUY supports up to 1 MHz I²C clock frequency across its full 1.7V–5.5V supply range, enabling faster configuration writes than 400 kHz EEPROMs. This is confirmed in Table 1-2 of DS20001709N, where FCLK = 1000 kHz is specified for 24FC02 at 1.7V ≤ VCC ≤ 5.5V. The 24FC02T-E/MUY achieves this using optimized internal timing and slope-controlled outputs.
Does the 24FC02T-E/MUY require external pull-up resistors on SDA and SCL lines?
Yes, the 24FC02T-E/MUY requires external pull-up resistors on both SDA and SCL lines because its I/O pins are open-drain. For 1 MHz operation, a 2 kΩ pull-up to VCC is recommended per Microchip's AC characteristics table. The 24FC02T-E/MUY does not integrate internal pull-ups, so omission will result in bus failure.
How is write protection implemented on the 24FC02T-E/MUY?
Write protection on the 24FC02T-E/MUY is implemented via the dedicated WP pin: tying WP to VCC disables all write operations (including byte and page writes) while preserving full read access. Tying WP to VSS enables normal read/write functionality. This hardware-level lock is active regardless of I²C command state and requires no software initialization.
What package type is used for the 24FC02T-E/MUY, and what are its key mechanical features?
The 24FC02T-E/MUY uses an 8-lead UDFN package designated Q4B (2 mm × 3 mm, wettable flanks). Its key mechanical features include a 0.55 mm profile, exposed thermal pad (connectable to VSS), and solderable side walls that enable automated optical inspection (AOI) of solder joints - critical for automotive-grade assembly traceability.
Is the 24FC02T-E/MUY AEC-Q100 qualified, and which grade does it meet?
Yes, the 24FC02T-E/MUY is AEC-Q100 qualified per the "Automotive AEC-Q100 Qualified" feature listed in DS20001709N. It meets Grade 1 requirements (–40°C to +125°C), verified through stress testing including HTOL, TC, and ESD. This qualification is explicitly tied to the 24FC02 variant in the Device Selection Table and applies to the E-temp grade denoted by "E" in 24FC02T-E/MUY.
