Product details
Overview
24FC16T-E/SN36KVAO from Microchip Technology Inc. is a 16-Kbit I²C-compatible serial EEPROM organized as eight 256 × 8-bit blocks, supporting 1 MHz clock frequency at 1.7–5.5 V supply, with hardware write-protection, 16-byte page buffer, and extended temperature operation to +125°C - used for configuration storage in automotive body control modules.
For engineers reviewing the 24FC16T-E/SN36KVAO datasheet, 24FC16T-E/SN36KVAO pinout, 24FC16T-E/SN36KVAO application, or 24FC16T-E/SN36KVAO equivalent, key selection criteria include I²C speed grade (1 MHz), extended-temp endurance (1M cycles), low-voltage operation (1.7 V), WP pin behavior, and SOIC-8 package compatibility with legacy board layouts.
Technical Context
The 24FC16T-E/SN36KVAO implements a two-wire I²C slave interface with Schmitt-trigger inputs and slope-controlled outputs to suppress noise and eliminate ground bounce. It uses an internal address pointer and page latches to support byte and 16-byte page writes with self-timed erase/write cycles.
Its memory architecture comprises eight independent 256-word blocks addressed via three block-select bits (B2–B0) in the I²C control byte; the device does not use A0–A2 pins, which are internally unconnected and may be left floating or tied to VSS/VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Kbit (2048 × 8), organized as eight 256-word blocks - enables modular configuration partitioning per subsystem. |
| I²C Clock Frequency | Up to 1 MHz at 1.7–5.5 V - supports high-throughput firmware parameter updates without bus contention. |
| Write Cycle Time | ≤5 ms per byte or page - defines minimum delay between successive write commands in time-critical logging. |
| Endurance | 1,000,000 erase/write cycles - ensures reliable operation over 10+ years in automotive infotainment settings. |
| Data Retention | ≥200 years at +25°C - guarantees nonvolatile storage integrity across product lifecycle without refresh. |
| Supply Voltage Range | 1.7 V to 5.5 V - allows direct interfacing with 1.8 V, 3.3 V, and 5 V microcontrollers without level-shifting. |
| Temperature Range | -40°C to +125°C (Extended grade) - qualified for under-hood and powertrain applications per AEC-Q100. |
Pinout & Package
Package: 8-Lead Plastic Small Outline (SOIC-N), narrow body (3.90 mm), JEDEC MS-012AA compliant, lead finish Matte Tin (Sn), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS | Ground reference | Primary return path for all internal logic and I/O; must be low-impedance connection to system GND plane. |
| WP | Hardware write-protect input | Logic-high disables all write operations (000–7FF); tied to VSS for full read/write access; no pull-up required. |
| SCL | Serial clock input | Asynchronous master-generated clock; requires external pull-up; timing-critical for 1 MHz operation (min. TLOW = 500 ns). |
| SDA | Serial data bidirectional I/O | Open-drain output; requires external pull-up (2 kΩ typical for 1 MHz); changes only during SCL low except for Start/Stop. |
| VCC | Power supply | Accepts 1.7–5.5 V; decoupling capacitor (0.1 μF ceramic) required within 5 mm of pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| 1 MHz I²C interface | Enables faster configuration loading vs. 400 kHz variants - reduces boot-time latency in real-time systems. |
| Schmitt-trigger inputs | Provides ≥50 mV hysteresis on SCL/SDA - rejects EMI-induced glitches on noisy automotive PCBs. |
| 16-byte page write buffer | Reduces I²C transaction count by up to 16× vs. byte writes - lowers CPU overhead and bus occupancy. |
| Hardware write-protect (WP) | Prevents accidental firmware corruption during field updates - eliminates need for software lock mechanisms. |
| AEC-Q100 qualified | Validated for automotive Grade 1 (−40°C to +125°C) - meets reliability requirements for safety-critical ECUs. |

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/SN | Max I²C speed 400 kHz; rated only to +85°C; same SOIC-8 package and pinout. | Not qualified for extended-temp automotive or industrial environments requiring >85°C operation. | Select when cost sensitivity outweighs speed/temp requirements and AEC-Q100 is unnecessary. |
| AT24C16D-SSHM-T | 1 MHz I²C; -40°C to +125°C; 1.7–5.5 V; but uses different write-protection scheme (software-configurable WP bit). | Lacks hardware WP pin - requires firmware coordination to prevent accidental writes during interrupt handling. | Choose if existing design already uses Atmel/Dialog EEPROMs and software-based protection is acceptable. |
Compared with 24AA16T-I/SN and AT24C16D-SSHM-T, the 24FC16T-E/SN36KVAO uniquely combines 1 MHz speed, hardware WP, and AEC-Q100 qualification in SOIC-8 - making it optimal for safety-critical automotive and industrial edge nodes where deterministic write blocking and fast parameter loading are mandatory.

FAQ
What is the maximum I²C clock frequency supported by the 24FC16T-E/SN36KVAO?
The 24FC16T-E/SN36KVAO supports up to 1 MHz I²C clock frequency across its full 1.7–5.5 V supply range and -40°C to +125°C operating temperature. This is confirmed in the Device Selection Table and AC Characteristics section of DS20001703M, distinguishing it from the 400 kHz-limited 24AA16 and 24LC16B variants. The 24FC16T-E/SN36KVAO maintains this speed even at minimum 1.7 V supply.
Does the 24FC16T-E/SN36KVAO require external pull-up resistors on SDA and SCL lines?
Yes, the 24FC16T-E/SN36KVAO 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 24FC16T-E/SN36KVAO does not include internal pull-ups, and omitting external resistors will prevent proper I²C communication.
How is write protection implemented on the 24FC16T-E/SN36KVAO?
Write protection on the 24FC16T-E/SN36KVAO is implemented via the dedicated WP pin: tying WP to VCC disables all write operations (including byte and page writes) across the entire 000–7FF address space, while reads remain fully functional. Tying WP to VSS enables full read/write access. This hardware-level protection is active regardless of I²C command state and requires no software intervention - a key feature of the 24FC16T-E/SN36KVAO.
Is the 24FC16T-E/SN36KVAO AEC-Q100 qualified?
Yes, the 24FC16T-E/SN36KVAO is explicitly AEC-Q100 qualified for Grade 1 (−40°C to +125°C), as stated in the Features section of DS20001703M. This qualification covers stress testing for temperature cycling, humidity bias, ESD, and other automotive reliability requirements - confirming its suitability for under-hood and powertrain applications where the 24FC16T-E/SN36KVAO is deployed.
What package type does the 24FC16T-E/SN36KVAO use, and is it compatible with standard SOIC-8 footprints?
The 24FC16T-E/SN36KVAO uses the 8-Lead Plastic Small Outline (SN) package - narrow body, 3.90 mm width, JEDEC MS-012AA compliant. Its mechanical dimensions (pitch = 1.27 mm, body width = 3.90 mm, overall length = 4.90 mm) match industry-standard SOIC-8 footprints, ensuring drop-in compatibility with existing PCB layouts designed for similar Microchip EEPROMs like the 24AA16T-I/SN or 24LC16BT-I/SN.
