Product details
Overview
24FC16T-E/MUY from Microchip Technology Inc. is a 16-Kbit I²C-compatible serial EEPROM organized as eight 256 × 8-bit blocks, operating from 1.7V to 5.5V with 1 MHz clock support, 5 ms max page write time, and extended temperature range (–40°C to +125°C). It features hardware write-protection via the WP pin and is packaged in an 8-lead UDFN (MUY) for space-constrained embedded systems.
For engineers reviewing the 24FC16T-E/MUY datasheet, 24FC16T-E/MUY pinout, 24FC16T-E/MUY application, or 24FC16T-E/MUY equivalent, this page delivers verified electrical specs, package mapping, I²C timing compliance at 1 MHz, endurance (1M cycles), and real-world use context for industrial control, automotive subsystems, and IoT node configuration storage.
Technical Context
The 24FC16T-E/MUY implements a two-wire I²C slave interface with Schmitt-trigger inputs and slope-controlled outputs to suppress noise and eliminate ground bounce. Its internal architecture includes a 16-byte page write buffer, self-timed erase/write cycle, and address pointer logic supporting current-address, random, and sequential read modes.
It supports full I²C protocol compliance-including Start/Stop detection, ACK polling during write cycles, and 7-bit slave addressing with fixed '1010' control code plus 3 block-select bits-while maintaining compatibility across VCC = 1.7V–5.5V without external level shifting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24AA16T-I/MUY | Same 8-lead UDFN package, but rated only for Industrial temp (–40°C to +85°C); max clock 400 kHz at VCC ≥2.5V | Lacks extended temperature qualification and 1 MHz speed - unsuitable for under-hood or high-ambient industrial use | Select only if cost sensitivity outweighs need for 125°C operation and higher-speed I²C |
| AT24C16D-MAHM-T | 16-Kbit I²C EEPROM in 8-UDFN; supports 1 MHz up to 2.5V–5.5V, but no AEC-Q100 qualification and only 100k endurance cycles | Not automotive-qualified; lower endurance limits rewrites in high-frequency logging scenarios | Acceptable for consumer-grade devices where AEC-Q100 and 1M-cycle endurance are not required |
Compared with 24AA16T-I/MUY, the 24FC16T-E/MUY adds extended temperature support and 1 MHz capability at low VCC; versus AT24C16D-MAHM-T, it provides AEC-Q100 validation and 10× higher endurance - critical for automotive and industrial deployments demanding long-term reliability.

FAQ
What is the maximum I²C clock frequency supported by the 24FC16T-E/MUY?
The 24FC16T-E/MUY supports up to 1 MHz I²C clock frequency across its full VCC range (1.7V–5.5V), unlike the 24AA16 (max 400 kHz) or 24LC16B (max 400 kHz, minimum 2.5V). This enables faster configuration writes and reduces bus contention in high-throughput systems. The 24FC16T-E/MUY maintains full AC timing compliance down to 1.7V, making it ideal for battery-powered designs where voltage headroom is limited.
Does the 24FC16T-E/MUY require external pull-up resistors on SDA and SCL lines?
Yes, the 24FC16T-E/MUY requires external pull-up resistors on both SDA and SCL lines because its I²C interface uses open-drain outputs. For 1 MHz operation, a 2 kΩ pull-up to VCC is recommended per Microchip's datasheet guidance. Incorrect pull-up values can cause timing violations or bus lockup - the 24FC16T-E/MUY's Schmitt-trigger inputs help tolerate marginal rise times, but proper resistor selection remains essential for reliable communication.
How does the WP pin function on the 24FC16T-E/MUY?
The WP (Write-Protect) pin on the 24FC16T-E/MUY is a logic-level input that disables all write operations when tied to VCC. When WP = VSS (ground), full read/write access is enabled across the entire 2048-byte memory map (addresses 000h–7FFh). This hardware-level protection prevents accidental overwrites during power transients or firmware bugs - a critical feature for automotive and medical applications where data integrity is mandatory. The 24FC16T-E/MUY does not support partial-page or software-based write protection.
Is the 24FC16T-E/MUY AEC-Q100 qualified, and what grade does it meet?
Yes, the 24FC16T-E/MUY is AEC-Q100 qualified and specified for Extended temperature grade (E), covering –40°C to +125°C ambient operation. This qualification includes stress testing for temperature cycling, humidity bias, and ESD per AEC-Q100 Rev H standards. The 24FC16T-E/MUY is approved for use in automotive body electronics, infotainment interfaces, and ADAS sensor modules where extended thermal performance and automotive-grade reliability are required.
What is the endurance rating and data retention specification for the 24FC16T-E/MUY?
The 24FC16T-E/MUY guarantees a minimum of 1,000,000 erase/write cycles per memory location and greater than 200 years of data retention at +25°C. These specifications are validated across the full extended temperature range (–40°C to +125°C), with derating applied per Microchip's Total Endurance™ Model. This makes the 24FC16T-E/MUY suitable for applications requiring frequent parameter updates - such as calibration logging or usage counters - while ensuring data persistence over the lifetime of industrial or automotive equipment.
