Product details
Overview
24VL014 from Microchip Technology Inc. is a 1 Kbit (128 × 8) I²C-compatible serial EEPROM designed for ultra-low-voltage embedded systems. It operates from 1.5V to 3.6V, draws ≤400 μA active current and ≤1 μA standby current, supports 100 kHz/400 kHz I²C bus speeds, and features hardware write protection (WP pin), Schmitt-trigger inputs, and 16-byte page write capability. It is used in battery-powered sensors, portable medical devices, and smart metering modules requiring nonvolatile memory with extended data retention.
For engineers reviewing the 24VL014 datasheet, 24VL014 pinout, 24VL014 application, or 24VL014 equivalent, this page delivers verified electrical specs, package-specific pin mapping, real-world use cases, and validated alternative parts - all grounded in Microchip's DS22129A datasheet and official packaging documentation.
Technical Context
The 24VL014 implements a true I²C slave interface with bidirectional SDA and unidirectional SCL, supporting standard-mode (100 kHz) and fast-mode (400 kHz) timing across its full 1.5–3.6 VCC range. Its internal address pointer enables sequential, random, and current-address read modes, while the 16-byte page buffer allows efficient burst writes without host-side byte-by-byte overhead.
Hardware write protection is implemented via the WP pin: tied to VCC, it locks the entire 00h–7Fh array; tied to VSS, writes are enabled. The device uses on-chip high-voltage generation for EEPROM programming and includes VCC threshold detection to inhibit writes below 1.0 V, preventing corruption during brown-out conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Kbit (128 × 8-bit array), organized as single block - supports simple firmware parameter storage without bank switching logic. |
| VCC Range | 1.5 V to 3.6 V - enables direct integration with Li-ion coin cells (e.g., CR2032), low-power MCUs, and energy-harvesting subsystems. |
| I²C Clock Speed | Up to 400 kHz (≥1.8 V); 100 kHz only (<1.8 V) - ensures compatibility with legacy microcontrollers while allowing faster updates in modern designs. |
| Write Cycle Time | 5 ms max (byte or page) - defines minimum inter-write delay; supports ACK polling to avoid fixed timeouts and maximize bus utilization. |
| Endurance & Retention | 1 million erase/write cycles; >200 years data retention at 25°C - suitable for field-deployed equipment requiring long-term reliability without maintenance. |
| ESD Protection | >4 kV HBM - provides robustness against handling and system-level ESD events in industrial and consumer assemblies. |
| Operating Temp | –20°C to +85°C - qualified for commercial and extended-temperature industrial environments, excluding automotive AEC-Q200. |
Pinout & Package
24VL014 is available in 8-pin PDIP, SOIC, TSSOP, MSOP, TDFN, and 6-pin SOT-23 packages. Pin functions are consistent across all variants except A2 and WP, which are unconnected in SOT-23. All packages share identical I²C protocol behavior and memory architecture.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1, A2 | Chip Select Inputs | Configure 3-bit slave address (1010xxxA); enable up to eight devices on one I²C bus (four for SOT-23, where A2 is NC). |
| SDA | Serial Data (bidirectional, open-drain) | Carries address/data; requires external pull-up (2 kΩ @ 400 kHz, 10 kΩ @ 100 kHz); changes only during SCL low. |
| SCL | Serial Clock (input) | Master-generated clock synchronizing all transfers; Schmitt-trigger input suppresses noise-induced glitches. |
| WP | Hardware Write-Protect Input | High = full-array lock (00h–7Fh); low = write enabled; not present on SOT-23 - write always enabled in that package. |
| VSS | Ground Reference | Return path for all internal circuitry; must be low-impedance and decoupled near VCC pin. |
| VCC | Power Supply | 1.5–3.6 V input; internal voltage detector disables writes below ~1.0 V to prevent data corruption during undervoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-voltage operation | Functional down to 1.5 V - eliminates need for level shifters when interfacing with sub-1.8 V MCUs or energy-harvesting PMICs. |
| Page write buffer (16 bytes) | Reduces I²C transaction count by up to 16× vs. byte writes - cuts bus occupancy and host CPU overhead in configuration storage tasks. |
| Schmitt-trigger SDA/SCL inputs | 0.05 VCC hysteresis + 50 ns spike suppression - tolerates noisy PCB traces and EMI without external RC filtering. |
| Output slope control | Controls SDA rise/fall slew rate - prevents ground bounce and signal integrity issues in dense mixed-signal layouts. |
| Factory QTP option | One-time programmable content pre-loaded at wafer/test - enables secure boot keys, calibration data, or unique identifiers shipped ready-to-use. |

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) | Same 1 Kbit size, 1.7–5.5 VCC, but lacks <1.8 V support and has higher 3 mA write current. | Not suitable for sub-1.8 V systems; requires voltage translation if paired with 1.5 V logic. | Select only if operating above 1.7 V and needing broader voltage margin; verify WP functionality matches design intent. |
| BR24G01FJ-WE2 (ROHM) | 1 Kbit, 1.6–5.5 VCC, 400 kHz I²C, but no WP pin and only 100 k-cycle endurance. | Unprotected writes increase risk of accidental corruption; lower endurance limits field update frequency. | Choose only for cost-sensitive, non-critical storage where write protection and longevity are secondary. |
Compared with AT24C01D-SSHM-T and BR24G01FJ-WE2, the 24VL014 uniquely supports true 1.5 V operation with hardware write protection and 1M-cycle endurance - making it the only choice for ultra-low-power, safety-critical, or long-lifecycle embedded storage.

FAQ
What is the minimum VCC required for reliable operation of the 24VL014?
The 24VL014 is fully specified to operate down to 1.5 V, with guaranteed I²C timing and write functionality across the full –20°C to +85°C temperature range. Below 1.5 V, the internal voltage detector disables write operations to prevent data corruption, though read access may remain functional depending on process variation. Always validate at 1.5 V in final design.
Does the 24VL014 support both 100 kHz and 400 kHz I²C speeds simultaneously?
No - the 24VL014 automatically adapts to the bus clock frequency: it supports 100 kHz when VCC < 1.8 V, and up to 400 kHz when VCC ≥ 1.8 V. The device does not negotiate speed; timing compliance is voltage-dependent per DS22129A Table 1-2.
How many 24VL014 devices can be connected on a single I²C bus?
Up to eight 24VL014 devices can be cascaded on one I²C bus using unique A2/A1/A0 combinations. For the 6-pin SOT-23 variant, A2 is unconnected, limiting the count to four devices (A1/A0 only). Each device occupies a distinct 7-bit slave address in the 1010xxx format.
Is hardware write protection available in all 24VL014 packages?
Hardware write protection via the WP pin is supported in all 8-pin packages (PDIP, SOIC, TSSOP, MSOP, TDFN), but is not available in the 6-pin SOT-23 package - where WP is unconnected and writes are always enabled. This is explicitly documented in DS22129A Section 2.4 and Table 2-1.
What is the maximum number of bytes that can be written in a single page write cycle of the 24VL014?
The 24VL014 supports up to 16 bytes per page write operation. The internal page buffer accepts these bytes sequentially after the initial word address, and commits them to EEPROM upon receipt of the Stop condition. Crossing physical page boundaries (every 16 bytes) causes wraparound - software must enforce alignment.
