Product details
Overview
24VL024T/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, featuring 400 μA max active current, 1 μA max standby current, and hardware write protection via the WP pin. It supports 100 kHz/400 kHz I²C bus speeds, 16-byte page writes, and operates across –20°C to +85°C in an 8-pin MSOP package - used for parameter storage in battery-powered sensor nodes and portable medical devices.
For engineers reviewing the 24VL024T/MS datasheet, 24VL024T/MS pinout, 24VL024T/MS application, or 24VL024T/MS equivalent, key selection considerations include its 1.5–3.6 V supply range, WP-enabled full-array hardware write protection, Schmitt-triggered SDA/SCL inputs for noise immunity, and compatibility with multi-device I²C buses up to eight units.
Technical Context
The 24VL024T/MS implements a true 2-wire I²C slave interface with fixed 7-bit address prefix '1010', where A0–A2 pins configure device addressing for multi-drop bus expansion. Its internal architecture includes a 16-byte page buffer, self-timed erase/write logic with auto-erase, and a VCC threshold detector disabling write operations below 1.0 V.
It uses Schmitt-trigger inputs on SDA and SCL with ≥50 ns spike suppression and hysteresis of 0.05×VCC, plus output slope control to minimize ground bounce. The WP pin (present only on 24VL024 variants) enables hardware-level protection of the entire 256-byte memory array when pulled high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 Kbit (256 × 8-bit), organized as single block - supports compact configuration storage without external address decoding. |
| Supply voltage | 1.5 V to 3.6 V - enables direct interfacing with 1.8 V and 3.3 V microcontrollers and operation from single-cell Li-ion or alkaline batteries. |
| I²C speed | Up to 400 kHz (≥1.8 V), 100 kHz (<1.8 V) - balances throughput and noise immunity in mixed-signal embedded systems. |
| Write endurance | 1 million erase/write cycles per byte - ensures long-term reliability in firmware update logging or calibration data cycling. |
| Data retention | 200 years at +25°C - guarantees nonvolatile storage integrity over product lifetime without refresh. |
| ESD protection | >4 kV HBM - provides robustness against handling and board-level electrostatic discharge events. |
| Operating temperature | –20°C to +85°C - qualified for industrial and consumer-grade portable electronics environments. |
Pinout & Package
24VL024T/MS is supplied in an 8-pin MSOP (Mini Small Outline Package) with 0.65 mm lead pitch and exposed pad option per Microchip DS22130A. Pin 1 is marked by laser dot; package meets Pb-free and RoHS requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Chip select input | User-configurable LSB of 3-bit slave address; hardwired to VSS or VCC to assign unique I²C address in multi-device systems. |
| A1 | Chip select input | Middle bit of slave address; enables up to eight devices on same I²C bus when combined with A0 and A2. |
| A2 | Chip select input | MSB of slave address; determines device selection alongside A0/A1; required for contiguous 16 Kbit expansion across multiple units. |
| VSS | Ground reference | Primary return path for all internal circuitry; must be low-impedance connection to system ground plane. |
| SDA | Serial data bidirectional line | Open-drain I²C data line requiring external pull-up; transmits addresses, commands, and data; changes only during SCL low. |
| SCL | Serial clock input | Master-generated clock synchronizing all I²C transfers; Schmitt-triggered for noise rejection on noisy PCBs. |
| WP | Hardware write-protect input | Active-high enable: ties entire 256-byte array read-only when pulled to VCC; disabled when tied to VSS - exclusive to 24VL024 family. |
| VCC | Power supply | Single 1.5–3.6 V supply powering EEPROM core and interface logic; internal VCC detector prevents writes below 1.0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.5 V - eliminates need for level shifters when interfacing with sub-2 V MCUs or energy-harvesting power rails. |
| Page write buffer | 16-byte buffer enables burst writes without repeated Start/Stop overhead - reduces I²C transaction time by up to 85% vs. byte writes. |
| Noise-immune interface | Schmitt-trigger inputs + 50 ns spike filtering on SDA/SCL - sustains reliable communication in EMI-prone motor control or RF modules. |
| Hardware write protection | WP pin disables all writes to full memory array - prevents accidental firmware corruption during power brownouts or debug sessions. |
| Multi-device scalability | Three address pins support up to eight 24VL024T/MS units on one I²C bus - simplifies design of modular sensor clusters with distributed storage. |

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 | No WP pin; supports 1.7–5.5 V; 1 MHz I²C; 400 Kcycles endurance | Lacks hardware write protection; higher voltage range suits 5 V legacy systems but requires level shifting for 1.5–1.8 V operation | Select when WP functionality is unnecessary and higher-speed I²C or wider VCC range is prioritized over ultra-low-voltage operation. |
| BR24G02FJ-3GE2 | 1.6–5.5 V; built-in write protect register (software-controlled); 400 Kcycles | Software-based protection lacks fail-safe behavior during power loss; no dedicated WP pin for hardware-enforced lockout | Choose when flexible, dynamic protection schemes are needed and system firmware can guarantee safe register access sequencing. |
Compared with AT24C02D-SSHM-T and BR24G02FJ-3GE2, the 24VL024T/MS uniquely delivers guaranteed 1.5 V operation with hardware WP - making it the only choice for battery-critical designs where voltage headroom and deterministic write blocking are mandatory.

FAQ
What is the minimum operating voltage for the 24VL024T/MS?
The 24VL024T/MS operates down to 1.5 V, with full I²C functionality (including 400 kHz mode) supported at 1.8 V and above. Below 1.8 V, maximum clock frequency drops to 100 kHz. Internal write operations are disabled if VCC falls below 1.0 V, ensuring data integrity during brownout conditions - a key reliability feature of the 24VL024T/MS.
Does the 24VL024T/MS have hardware write protection, and how is it implemented?
Yes, the 24VL024T/MS includes a dedicated WP (Write Protect) pin that enables hardware-level protection of the entire 256-byte memory array. When WP is pulled high to VCC, all write and page-write operations are blocked; pulling WP low to VSS disables protection. This function is exclusive to the 24VL024 variant and is physically present on the 24VL024T/MS MSOP package.
How many 24VL024T/MS devices can be connected to a single I²C bus?
Up to eight 24VL024T/MS devices can be connected to one I²C bus using the A0, A1, and A2 address pins to generate unique 3-bit chip select codes. Each device occupies a distinct 256-byte address space, enabling up to 16 Kbits of contiguous EEPROM storage - a capability confirmed in the 24VL024T/MS functional description and bus timing specifications.
What is the page write capacity of the 24VL024T/MS, and what happens if more than 16 bytes are sent?
The 24VL024T/MS supports a 16-byte page write buffer. If more than 16 bytes are transmitted before the Stop condition, the address counter wraps within the current page boundary, overwriting earlier bytes in the same page. This behavior is explicitly defined in the 24VL024T/MS datasheet section 6.2 and requires firmware to enforce page-aligned writes.
Is the 24VL024T/MS compatible with standard I²C protocols and timing requirements?
Yes, the 24VL024T/MS is fully I²C™-compatible, supporting standard Start/Stop conditions, ACK/NACK handshaking, and both 100 kHz and 400 kHz modes. Its AC characteristics - including THD:STA, TSU:DAT, and TAA - meet I²C specification limits across its full 1.5–3.6 V supply range, as verified in Table 1-2 of the official 24VL024T/MS datasheet.
