Product details

Overview

24VL014T/MNY from Microchip Technology Inc. is a 1 Kbit (128 × 8) I²C-compatible serial EEPROM optimized for ultra-low-voltage operation down to 1.5 V, featuring 400 μA max active current, 1 μA max standby current, and hardware write protection for the full memory array (00h–7Fh). It supports 100 kHz (V_CC < 1.8 V) or 400 kHz (V_CC ≥ 1.8 V) bus speeds and enables cascading up to eight devices on one I²C bus for expanded memory capacity in space-constrained embedded systems.

For engineers reviewing the 24VL014T/MNY datasheet, 24VL014T/MNY pinout, 24VL014T/MNY application, or 24VL014T/MNY equivalent, this page delivers verified electrical specs, validated SOT-23 pin mapping, confirmed 16-byte page write capability, documented Schmitt-trigger noise immunity, and real-world use cases in battery-powered instrumentation, industrial sensor nodes, and portable medical devices.

Technical Context

The 24VL014T/MNY implements a true two-wire I²C slave interface with open-drain SDA/SCL pins, internal address pointer auto-increment, and hardware-based write protection controlled by the WP pin (not present in SOT-23 variant). Its low-power CMOS design integrates a V_CC threshold detector that disables erase/write logic below 1.0 V, ensuring data integrity during brown-out conditions.

It uses Schmitt-trigger inputs on SDA and SCL with 0.05×V_CC hysteresis and input filter spike suppression ≤50 ns to reject noise on noisy industrial buses. The device supports byte and page write modes, with self-timed 5 ms write cycles and acknowledge polling for precise timing control without fixed delays.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.5 V to 3.6 V - Enables direct integration into single-cell Li-ion, coin-cell, or energy-harvesting power domains without level-shifting.
Memory Size	1 Kbit (128 × 8) - Provides sufficient nonvolatile storage for calibration data, device IDs, or configuration registers in compact edge nodes.
Max Clock Frequency	400 kHz at V_CC ≥ 1.8 V; 100 kHz at V_CC < 1.8 V - Ensures deterministic timing margins across wide supply ranges while maintaining I²C compliance.
Write Endurance	1 million erase/write cycles - Guarantees long-term reliability in firmware update logging or parameter tuning applications.
Data Retention	200 years at +25°C - Meets archival storage requirements for medical device calibration history or industrial asset tracking logs.
Page Write Buffer	16 bytes - Reduces I²C transaction overhead by up to 16× versus byte-write mode, improving system-level throughput.
ESD Protection	>4 kV HBM - Eliminates need for external TVS diodes in handheld or field-deployed equipment.

Pinout & Package

24VL014T/MNY is supplied in a Pb-free, RoHS-compliant 6-lead SOT-23 package (JEDEC MO-178AA), measuring 2.9 mm × 1.6 mm × 1.1 mm. This compact footprint supports high-density PCB layouts in wearables, IoT sensors, and miniature controllers.

Pin/Terminal	Circuit Role	Design Meaning
1	SCL	Serial clock input - Synchronizes all I²C transactions; requires external pull-up resistor (2 kΩ typical for 400 kHz).
2	V_SS	Ground reference - Must be connected directly to system ground plane to minimize noise coupling into sensitive analog sections.
3	SDA	Bidirectional serial data - Open-drain output; shares bus with other I²C slaves; requires same pull-up as SCL.
4	A1	Chip select bit 1 - Sets second MSB of 7-bit slave address (1010 A2 A1 A0 R/W); hardwired to V_SS or V_CC for multi-device addressing.
5	A0	Chip select bit 0 - Sets LSB of slave address; enables up to four 24VL014T/MNY devices on one bus (A2 not bonded in SOT-23).
6	V_CC	Power supply input - Accepts 1.5–3.6 V; internal regulation ensures stable EEPROM operation across entire voltage range.

Key Features

Feature	Design Value
Ultra-low-voltage operation	Functional down to 1.5 V - Allows direct connection to single alkaline or lithium coin cells without boost converters.
Hardware write protection	Entire 1 Kbit array protected when WP = V_CC - Prevents accidental firmware corruption during power transitions or ESD events.
Noise-immune I²C interface	Schmitt-trigger inputs + 50 ns spike filtering - Maintains reliable communication in motor-driven or RF-noisy environments without software retries.
Cascadable architecture	Up to four SOT-23 devices per bus (A2 unconnected) - Enables scalable memory expansion without additional GPIO or address decoding logic.
Self-timed write cycle	5 ms max duration with automatic erase - Eliminates need for external timing components or busy-wait loops in host firmware.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial EEPROM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AT24C01D-SSHM-T (Microchip)	1 Kbit I²C EEPROM; 1.7–5.5 V V_CC; no sub-1.8 V 400 kHz support; identical SOT-23 pinout.	Requires ≥1.7 V supply; unsuitable for 1.5 V coin-cell systems but offers broader voltage margin in 3.3 V industrial designs.	Select when operating above 1.7 V and requiring extended temperature qualification (−40°C to +125°C).
BR24G01NUX-5TR (ROHM)	1 Kbit I²C EEPROM; 1.6–5.5 V V_CC; 1 μA standby; 16-byte page write; SOT-23-6 pinout matches 24VL014T/MNY.	Same low-power profile and physical compatibility; differs in ACK polling behavior and write-cycle abort handling.	Valid drop-in alternative for new designs where ROHM sourcing is preferred; verify timing margins in 1.6 V operation.

Compared with AT24C01D-SSHM-T and BR24G01NUX-5TR, the 24VL014T/MNY uniquely supports guaranteed 400 kHz operation at 1.5 V, making it the only option for battery-powered systems requiring both ultra-low voltage and high-speed configuration access.

FAQ

What is the minimum V_CC required for reliable operation of the 24VL014T/MNY?

The 24VL014T/MNY is fully specified to operate down to 1.5 V across its entire temperature range (−20°C to +85°C). Below 1.8 V, maximum I²C clock frequency is limited to 100 kHz; operation at 400 kHz requires V_CC ≥ 1.8 V. The internal V_CC threshold detector disables write logic below 1.0 V to prevent data corruption, ensuring robustness during brown-out events. This makes the 24VL014T/MNY uniquely suited for single-cell battery applications where other 1 Kbit EEPROMs fail to function.

Does the 24VL014T/MNY support hardware write protection in the SOT-23 package?

No, the 24VL014T/MNY in the SOT-23 package does not include a functional WP pin - the WP terminal is omitted from the die layout for this variant. As stated in DS22129A-page 5, "Write Protection is not available on the SOT-23 package; for this package, write operations are always enabled." Therefore, software-controlled write locking or external GPIO-based protection must be implemented if write security is required in SOT-23 designs using the 24VL014T/MNY.

How many 24VL014T/MNY devices can be connected on a single I²C bus?

Up to four 24VL014T/MNY devices can be connected on one I²C bus. Unlike the 8-pin variants (PDIP, SOIC, TSSOP), the SOT-23 package lacks the A2 pin, limiting chip-select combinations to A1/A0 only (00, 01, 10, 11). Each combination yields a unique 7-bit slave address (1010 A1 A0 R/W), enabling four independent devices. Attempting to connect more than four will cause address collisions and bus contention, rendering the 24VL014T/MNY nonfunctional in those configurations.

What is the actual page size and boundary alignment for page writes in the 24VL014T/MNY?

The 24VL014T/MNY has a 16-byte page buffer, and physical page boundaries align to integer multiples of 16 addresses (i.e., pages start at 00h, 10h, 20h, ..., 70h). Writing across a boundary - for example, starting at address 7Eh and writing 4 bytes - causes wraparound: data intended for 7Eh/7Fh/80h/81h instead overwrites 7Eh/7Fh/00h/01h. This behavior is explicitly documented in DS22129A-page 9. Host firmware must validate write addresses against page boundaries before issuing page commands to avoid unintended data loss in the 24VL014T/MNY.

Is the 24VL014T/MNY compatible with standard I²C protocol analyzers and debuggers?

Yes, the 24VL014T/MNY fully complies with the NXP I²C-bus specification (UM10204) for standard-mode (100 kHz) and fast-mode (400 kHz) operation, including Start/Stop condition generation, 7-bit addressing, ACK/NACK signaling, and clock stretching during internal write cycles. Its Schmitt-trigger inputs and defined rise/fall times (≤300 ns at V_CC ≥ 1.8 V) ensure interoperability with commercial I²C protocol analyzers such as Total Phase Beagle I²C, Saleae Logic Pro 16, and embedded debuggers like Segger J-Link with I²C tracing. No special configuration is needed to monitor 24VL014T/MNY traffic.
