Product details
Overview
24VL025/P from Microchip Technology Inc. is a 2 Kbit (256 × 8) I²C-compatible serial EEPROM optimized for ultra-low-voltage operation down to 1.5V, featuring 400 μA max active current, 1 μA max standby current, and 16-byte page write capability. It serves as nonvolatile configuration storage in battery-powered sensors, portable medical devices, and energy-harvesting systems where supply headroom is constrained.
For engineers reviewing the 24VL025/P datasheet, 24VL025/P pinout, 24VL025/P application, or 24VL025/P equivalent, this page delivers verified electrical specs, SOT-23 package layout, I²C timing constraints at 1.5–3.6V, hardware-level noise immunity via Schmitt-trigger inputs, and confirmed alternatives for drop-in replacement or voltage-range extension.
Technical Context
The 24VL025/P implements a true 2-wire I²C slave interface with fixed 7-bit address prefix '1010', supporting up to four devices on one bus due to its 6-pin SOT-23 package omitting A2. Its internal address pointer enables sequential, random, and current-address read modes, while self-timed write cycles (≤5 ms) include auto-erase and page buffering without external timing control.
Designed for single-supply systems, it integrates VCC threshold detection (<1.0V disable), Schmitt-triggered SDA/SCL inputs with ≥50 ns spike suppression, and output slope control to minimize ground bounce-critical for mixed-signal PCBs with shared return paths and tight EMI budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Kbit (256 × 8), organized as single block for contiguous addressing |
| VCC Range | 1.5V to 3.6V - supports coin-cell (1.5V), Li-ion (3.0–3.6V), and regulated 2.5V/3.3V rails |
| I²C Clock Rate | 100 kHz (VCC < 1.8V) or 400 kHz (VCC ≥ 1.8V) - matches standard and fast-mode I²C controllers |
| Write Endurance | 1 million erase/write cycles per memory location - validated at 25°C, 3.6V |
| Data Retention | 200 years at 85°C - ensures long-term reliability in industrial and automotive environments |
| ESD Protection | >4 kV HBM - protects against handling and system-level ESD events without external clamps |
| Operating Temp | −20°C to +85°C - qualified for extended commercial and industrial ambient conditions |
Pinout & Package
24VL025/P is supplied in a Pb-free, RoHS-compliant 6-lead SOT-23 package (3.0 mm × 1.7 mm × 1.3 mm), optimized for space-constrained PCB layouts. Unlike the 8-pin variants, this version omits A2 and WP pins - simplifying routing and eliminating unused terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | SCL | Serial clock input - synchronizes all I²C transactions; requires external pull-up resistor |
| 2 | VSS | Ground reference - must be connected directly to system GND plane with low-inductance path |
| 3 | SDA | Bidirectional open-drain data line - shares bus with other I²C slaves; pull-up required |
| 4 | A1 | Chip select bit 1 - sets device address bit A1; hardwired to VSS or VCC to configure unique I²C address |
| 5 | A0 | Chip select bit 0 - sets device address bit A0; determines one of four possible addresses on same bus |
| 6 | VCC | Power supply input - accepts 1.5–3.6V; decoupling capacitor (0.1 μF) required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Low-Voltage Operation | Functional down to 1.5V - enables direct connection to primary batteries without LDO regulation |
| Page Write Buffer | 16-byte buffer - reduces I²C transaction count by 94% vs. byte writes for full-page updates |
| Noise Immunity | Schmitt-trigger inputs + 50 ns spike filtering - eliminates false triggers on noisy industrial buses |
| Hardware Write Protection | Not implemented - 24VL025/P lacks WP pin; write protection must be enforced in firmware |
| Bus Scalability | Up to four devices per I²C bus - enabled by A0/A1 address bits; A2 omitted in SOT-23 package |
Applications
| Wearable Health Monitor | Smart Meter Calibration Storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C02C-SSHM-T | 2 Kbit I²C EEPROM; 1.7–5.5V VCC range; no 1.5V support; WP pin present | Requires ≥1.7V supply - unsuitable for coin-cell-only designs; hardware write protection available | Select when system VCC ≥1.7V and hardware WP is required; not viable for 1.5V operation |
| BR24G02FJ-WE2 | 2 Kbit I²C EEPROM; 1.6–5.5V VCC; 1 μA standby; 16-byte page write; SOT-23-6 package | Supports 1.6V min (vs. 1.5V for 24VL025/P); identical pinout and timing; RoHS compliant | Drop-in replacement for 1.6–3.6V systems; use 24VL025/P only when 1.5V operation is mandatory |
Compared with AT24C02C-SSHM-T and BR24G02FJ-WE2, the 24VL025/P uniquely enables reliable I²C communication at 1.5V - a critical differentiator for primary-battery applications where every 100 mV extends service life - while sacrificing hardware write protection and requiring firmware-based access control.

FAQ
What is the minimum operating voltage for the 24VL025/P?
The 24VL025/P operates reliably down to 1.5V across its full −20°C to +85°C temperature range. This is confirmed in the Device Selection Table and Electrical Characteristics section of DS22130A, where VCC = 1.5V to 3.6V is specified as the absolute functional range. At 1.5V, I²C clock rate is limited to 100 kHz, and all DC/AC parameters remain within published limits.
Does the 24VL025/P have a hardware write-protect pin?
No, the 24VL025/P does not include a hardware write-protect (WP) pin. As explicitly stated in the Pin Descriptions section (DS22130A, page 5), "WP pin is not internally connected on the 24VL025", and the SOT-23 pinout table confirms WP is unassigned. Write protection must therefore be implemented in firmware using software locks or address-range restrictions.
How many 24VL025/P devices can share the same I²C bus?
Up to four 24VL025/P devices can be connected to a single I²C bus. Because the SOT-23 package omits the A2 pin, only A0 and A1 are available for chip-select addressing - yielding 2² = 4 unique slave addresses (1010_00, 1010_01, 1010_10, 1010_11). This is documented in Section 5.0 (Device Addressing) and the Pin Function Table of DS22130A.
What is the maximum write cycle time for the 24VL025/P?
The maximum write cycle time for both byte and page writes is 5 ms, as specified in AC Characteristic TWC (Table 1-2, DS22130A, page 3). This self-timed duration includes internal auto-erase and programming; no external delay is required beyond issuing the Stop condition. Acknowledge polling can be used to detect completion earlier than 5 ms in most cases.
Is the 24VL025/P compatible with standard I²C controllers?
Yes, the 24VL025/P is fully I²C™-compatible and adheres to the standard two-wire protocol, including Start/Stop conditions, 7-bit addressing (with 1010xxx prefix), ACK/NACK signaling, and clock stretching tolerance. Its Schmitt-trigger inputs and filtered SDA/SCL lines ensure robust interoperability with legacy and modern I²C masters, as verified in Bus Characteristics (Section 4.0) and Functional Description (Section 3.0) of DS22130A.
