Product details
Overview
24FC04T-E/MUY from Microchip Technology Inc. is a 4-Kbit I²C-compatible serial EEPROM organized as two 256 × 8-bit blocks, supporting 1 MHz clock frequency at 1.7V–5.5V supply, with hardware write-protection, 16-byte page write buffer, and extended temperature operation from –40°C to +125°C. It is used in automotive body control modules for storing calibration data and configuration parameters.
For engineers reviewing the 24FC04T-E/MUY datasheet, 24FC04T-E/MUY pinout, 24FC04T-E/MUY application, or 24FC04T-E/MUY equivalent, key selection criteria include its 1 MHz I²C speed at low voltage (1.7V), extended-temp endurance (>1M cycles), and wettable-flank UDFN package suitability for automated optical inspection in high-reliability automotive PCB assembly.
Technical Context
The 24FC04T-E/MUY implements a two-wire I²C interface with Schmitt-trigger inputs and slope-controlled outputs to suppress ground bounce and bus noise. Its internal architecture includes a 16-byte page latch, HV generator for EEPROM programming, and address pointer logic enabling current-address, random, and sequential read modes.
It supports full I²C protocol compliance-including Start/Stop detection, ACK polling during write cycles, and R/W bit–controlled block addressing-with dedicated WP pin for hardware-level memory protection across the entire 000h–1FFh address space.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Interface | I²C-compatible two-wire serial bus, compatible with standard microcontroller I²C peripherals without level-shifting |
| Max Clock Frequency | 1 MHz at 1.7V–5.5V, enabling faster configuration writes than 400 kHz alternatives in time-critical boot sequences |
| Write Cycle Time | 5 ms maximum (byte or page), deterministic timing for host firmware timeout handling |

Pinout & Package
24FC04T-E/MUY uses an 8-lead Wettable Flanks UDFN (Q4B) package-0.8 mm × 1.2 mm, 0.4 mm pitch-with exposed pad connected to VSS for thermal and EMI performance. Pin 1 is marked by chamfered corner.
| 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 in 24FC04 family; no impact on device addressing |
| A2 | Address Input | No internal connection; not bonded; no effect on I²C client address (fixed as 1010xxx) |
| VSS | Ground | Reference node for all signals; exposed pad must be soldered to PCB ground plane |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up; transmits addresses, data, and ACK/NACK |
| SCL | Serial Clock Input | Master-generated clock synchronizing all I²C transfers; Schmitt-trigger input rejects noise |
| WP | Write-Protect Input | Hardware lock: tied to VCC disables all writes; tied to VSS enables full read/write access |
| VCC | Power Supply | 1.7V–5.5V operation; supports direct connection to 1.8V, 2.5V, 3.3V, or 5V system rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA04T-I/MS | Max clock 400 kHz; operates down to 1.7V but lacks 1 MHz capability; I-temp only (–40°C to +85°C) | Suitable for cost-sensitive consumer electronics where extended temp and high-speed writes are unnecessary | Select when budget constraints outweigh need for automotive-grade speed/temp performance |
| AT24C04D-SSHM-T | Same 4-Kbit size and I²C interface; 1 MHz capable but requires ≥2.5V supply; no AEC-Q100 qualification | Applicable in industrial controls with stable 3.3V rails but not certified for automotive under-hood environments | Choose for non-automotive designs needing 1 MHz speed and Microchip-independent sourcing |
Compared with 24FC04T-E/MUY, the 24AA04T-I/MS trades speed and temperature range for lower cost, while the AT24C04D-SSHM-T offers 1 MHz operation without AEC-Q100 validation-making 24FC04T-E/MUY uniquely suited for safety-critical, high-temp automotive firmware storage.

FAQ
What is the maximum I²C clock frequency supported by the 24FC04T-E/MUY?
The 24FC04T-E/MUY supports up to 1 MHz I²C clock frequency across its full 1.7V–5.5V supply range. This is confirmed in Table 1-2 of DS20001708P, where FCLK = 1000 kHz is specified for 1.7V ≤ VCC ≤ 5.5V. This distinguishes it from the 24AA04 (max 400 kHz) and 24LC04B (max 400 kHz below 2.5V).
Does the 24FC04T-E/MUY require external pull-up resistors on SDA and SCL lines?
Yes, the 24FC04T-E/MUY requires external pull-up resistors on both SDA and SCL lines because its I²C interface uses open-drain outputs. Section 2.2 specifies typical values of 2 kΩ for 1 MHz operation. The exact value depends on bus capacitance and desired rise time, but omission will prevent proper I²C communication.
How is write protection implemented on the 24FC04T-E/MUY?
Write protection on the 24FC04T-E/MUY is implemented via the WP pin: when tied to VCC, the entire memory array (000h–1FFh) is write-inhibited while reads remain fully functional. When tied to VSS, full read/write access is enabled. This hardware-level lock operates independently of I²C commands and persists across power cycles.
Is the 24FC04T-E/MUY AEC-Q100 qualified, and what grade does it meet?
Yes, the 24FC04T-E/MUY is AEC-Q100 qualified and rated for Extended temperature range (–40°C to +125°C), meeting Grade 1 requirements. This is explicitly stated in the "Features" section of DS20001708P and confirmed in the Device Selection Table, where 24FC04 lists "I, E" temp ranges and "Automotive AEC-Q100 Qualified".
What package type does the 24FC04T-E/MUY use, and why is it significant?
The 24FC04T-E/MUY uses an 8-lead Wettable Flanks UDFN (Q4B) package-0.8 mm × 1.2 mm with 0.4 mm pitch. Its wettable flanks enable reliable automated optical inspection (AOI) of solder joints, a critical requirement for zero-defect manufacturing in automotive electronics production lines.
