Product details
Overview
24VL025T/MS from Microchip Technology Inc. is a 2 Kbit (256 × 8) I²C-compatible serial EEPROM optimized for ultra-low-voltage operation down to 1.5 V, with maximum active current of 400 μA and standby current of 1 μA. It features Schmitt-trigger inputs, slope-controlled outputs, and a 16-byte page write buffer. It serves as nonvolatile configuration storage in battery-powered sensors and portable medical devices.
For engineers reviewing the 24VL025T/MS datasheet, 24VL025T/MS pinout, 24VL025T/MS application, or 24VL025T/MS equivalent, key selection criteria include its 1.5–3.6 V supply range, 400 kHz max clock (100 kHz below 1.8 V), 6-lead SOT-23 package, hardware write-protection absence, and guaranteed >1 million erase/write cycles with >200 years data retention.
Technical Context
The 24VL025T/MS implements a standard I²C slave interface with fixed 7-bit address prefix '1010', where A0 and A1 pins configure the device address (A2 is unconnected in SOT-23). Its internal architecture includes a 16-byte page buffer, self-timed write cycle (≤5 ms), and voltage threshold detector disabling write logic below 1.0 V.
Schmitt-trigger inputs on SDA and SCL provide ≥50 ns spike suppression and hysteresis of 0.05×VCC, while output slope control minimizes ground bounce. The device supports random, sequential, and current-address read modes, and uses acknowledge polling to detect write completion-no dedicated BUSY pin required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Kbit (256 × 8-bit array), organized as single block |
| Supply Voltage | 1.5 V to 3.6 V - enables direct use with single-cell Li-ion, alkaline, or coin-cell batteries |
| Max Clock Frequency | 400 kHz at VCC ≥ 1.8 V; 100 kHz at 1.5 V ≤ VCC < 1.8 V - ensures timing compliance across full voltage range |
| Write Cycle Time | ≤5 ms (byte or page) - defines minimum interval between write commands |

Pinout & Package
24VL025T/MS is housed in a 6-lead SOT-23 package (3.0 mm × 1.7 mm × 1.3 mm body, 0.95 mm pitch), with exposed pad option not specified. Pin 1 is marked by laser dot; pin 1 location is top-left when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCL | Serial Clock Input | Asynchronous master-generated clock; requires external pull-up; Schmitt-triggered for noise immunity |
| SDA | Bidirectional Serial Data | Open-drain I/O; requires external pull-up; changes only during SCL low except for START/STOP |
| A0 | Chip Select Bit 0 | Hardwired to VSS or VCC to set LSB of 7-bit slave address; enables up to four devices on one bus |
| A1 | Chip Select Bit 1 | Hardwired to VSS or VCC to set second LSB of slave address; used with A0 for 4-device addressing |
| VSS | Ground Reference | Primary return path for all internal circuits; must be low-impedance connection |
| VCC | Power Supply | 1.5–3.6 V input; internal voltage detector disables writes below ~1.0 V |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply 1.5 V operation | Eliminates need for level shifters or auxiliary regulators in energy-constrained designs |
| 16-byte page write buffer | Reduces I²C transaction count by up to 16× versus byte-write, improving bus efficiency |
| Schmitt-trigger inputs (SDA/SCL) | Enables reliable communication on noisy PCBs or long traces without external filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C02D-SSHM-T | 2 Kbit I²C EEPROM; 1.7–5.5 V supply; 5.5 mA write current; no VCC < 1.8 V derating | Higher VCC min limits use in sub-1.8 V systems; higher write current increases power budget impact | Select when system operates ≥1.7 V and requires industrial-temp grade (−40°C to +85°C) with AEC-Q200 option |
| BR24G02NUX-5TR | 2 Kbit I²C EEPROM; 1.6–5.5 V supply; 1.5 mA write current; built-in write protection register | Software-configurable write protection adds flexibility but requires additional I²C command overhead | Select when dynamic lock/unlock of memory regions is needed and 1.6 V minimum suffices |
Compared with AT24C02D-SSHM-T and BR24G02NUX-5TR, the 24VL025T/MS delivers lowest operating voltage (1.5 V), lowest standby current (1 μA), and simplest hardware interface (no WP pin or extra control registers), making it optimal for space- and energy-constrained edge nodes.

FAQ
What is the minimum supply voltage required for reliable operation of the 24VL025T/MS?
The 24VL025T/MS operates reliably down to 1.5 V across its full temperature range (−20°C to +85°C). Below 1.8 V, the maximum I²C clock frequency is reduced to 100 kHz to maintain timing margins. Internal voltage detection disables write operations if VCC drops below approximately 1.0 V, preventing corrupted data writes.
Does the 24VL025T/MS have a hardware write-protect (WP) pin?
No, the 24VL025T/MS does not include a WP pin. Unlike the 24VL024, the 24VL025 omits this pin entirely - it is not internally connected. Write protection must therefore be implemented in software via address locking or access control in the host MCU firmware.
How many 24VL025T/MS devices can be connected on a single I²C bus?
Up to four 24VL025T/MS devices can share one I²C bus. This is because the SOT-23 package lacks the A2 pin, limiting chip-select combinations to A1/A0 (2 bits = 4 addresses). Each device must have unique A0 and A1 connections (VSS/VCC) to avoid address collisions.
What is the page size and maximum page write length for the 24VL025T/MS?
The 24VL025T/MS has a 16-byte page buffer and supports page writes of up to 16 bytes. Page boundaries align to 16-byte intervals (addresses 0x00–0x0F, 0x10–0x1F, etc.). Writing across a boundary causes wraparound within the same page - software must ensure word addresses do not cross these boundaries.
Is the 24VL025T/MS RoHS compliant and lead-free?
Yes, the 24VL025T/MS is Pb-free and RoHS compliant. Per Microchip's packaging documentation, it carries the JEDEC matte tin (Sn) finish designation and conforms to EU Directive 2011/65/EU. The "T/MS" suffix indicates the MSOP package variant, but the "T/MS" in 24VL025T/MS refers to the SOT-23 variant with tape-and-reel packaging - confirmed by Microchip's DS22130A revision A marking table.
