Product details
Overview
24VL024T/MNY from Microchip Technology Inc. is a 2 Kbit I²C-compatible serial EEPROM organized as 256 × 8-bit memory, operating from 1.5V to 3.6V with max active current of 400 μA and standby current of 1 μA. It supports 100 kHz/400 kHz clock rates, features hardware write protection via WP pin, and uses Schmitt-trigger inputs for noise immunity in low-voltage embedded systems.
For engineers reviewing the 24VL024T/MNY datasheet, 24VL024T/MNY pinout, 24VL024T/MNY application, or 24VL024T/MNY equivalent, key selection criteria include single-supply 1.5V operation, page-write buffer (up to 16 bytes), >1 million erase/write cycles, 200-year data retention, and I²C bus compatibility with cascading support for up to eight devices.
Technical Context
The 24VL024T/MNY implements a 2-wire I²C slave interface with fixed 4-bit control code (1010b) and 3-bit chip-select address (A2–A0), enabling up to eight devices on one bus. Its internal address pointer auto-increments during sequential reads and wraps from FFh to 00h.
Write operations use self-timed internal erase/write cycles (max 5 ms), supported by acknowledge polling to detect completion. Hardware write protection is active when WP = VCC, locking the full 256-byte array - a feature exclusive to the 24VL024 variant and confirmed present in 24VL024T/MNY per package marking and pinout documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Kbit (256 × 8-bit), contiguous single-block organization |
| Supply Voltage Range | 1.5V to 3.6V - enables direct interfacing with 1.8V/2.5V/3.3V logic without level shifters |
| Max Clock Frequency | 400 kHz at VCC ≥ 1.8V; 100 kHz at 1.5V ≤ VCC < 1.8V - ensures timing compliance across full voltage range |
| Write Cycle Time | 5 ms maximum - defines minimum interval between write commands; verified for byte and page writes |
| Endurance | 1 million erase/write cycles per memory location - validated at 25°C, VCC = 3.6V |
| Data Retention | 200 years at +25°C - guaranteed nonvolatile storage lifetime under nominal conditions |
| ESD Protection | ≥ 4,000V HBM - protects against handling-induced electrostatic discharge in assembly and field environments |
Pinout & Package
24VL024T/MNY is supplied in an 8-pin TSSOP package (3.0 mm × 4.4 mm, 0.65 mm pitch), pin-compatible with SOIC, PDIP, MSOP, and TDFN variants. Pin functions are electrically identical across all 8-pin packages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Chip Select Input | User-configurable LSB of 3-bit device address; hardwired to VSS or VCC to select one of eight possible I²C addresses |
| A1 | Chip Select Input | Middle bit of device address; determines unique slave address when multiple 24VL024T/MNY devices share the same I²C bus |
| A2 | Chip Select Input | MSB of device address; enables up to eight independent devices on one bus (A2–A0 = 000b to 111b) |
| VSS | Ground Reference | Primary return path for all internal circuitry and I/O; must be connected before VCC to ensure proper power-up sequencing |
| SDA | Serial Data I/O | Open-drain bidirectional line requiring external pull-up; carries address, command, and data; changes only during SCL low |
| SCL | Serial Clock Input | Master-generated clock synchronizing all data transfers; Schmitt-trigger input suppresses noise on rising/falling edges |
| WP | Hardware Write-Protect | Active-high enable for full-array lock (00h–FFh); tied to VCC for protection, VSS for normal write access - exclusive to 24VL024 family |
| VCC | Power Supply | Single supply input supporting 1.5V–3.6V operation; internal voltage detector disables writes below ~1.0V to prevent corruption |
Key Features
| Feature | Design Value |
|---|---|
| Low-Voltage Operation | Functional down to 1.5V - eliminates need for voltage regulators in battery-powered or energy-harvesting systems |
| 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 |
| Schmitt Trigger Inputs | On SDA/SCL pins with 0.05×VCC hysteresis - rejects noise spikes ≤50 ns and prevents false edge detection on noisy PCBs |
| Hardware Write Protection | WP pin controls full-array lock - provides tamper-resistant configuration storage independent of firmware control |
| Cascadable Architecture | Supports up to eight 24VL024T/MNY devices on one I²C bus - scales EEPROM capacity to 16 Kbit without additional controllers |

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; 1.7V–5.5V supply; no hardware WP pin; 1 MHz max clock | Lacks dedicated write-protect pin - requires software-based protection or external logic for secure configuration storage | Choose when higher speed (1 MHz) and wider voltage range are prioritized over hardware-level write security |
| BR24G02FJ-WE2 | 2 Kbit I²C EEPROM; 1.6V–5.5V supply; built-in WP function but implemented via internal register, not dedicated pin | WP functionality is software-controlled and volatile across power cycles - cannot guarantee permanent lockout like 24VL024T/MNY's hardware WP | Prefer when register-based flexibility is needed, but avoid where regulatory compliance mandates physical write-disable capability |
Compared with AT24C02D-SSHM-T and BR24G02FJ-WE2, the 24VL024T/MNY uniquely delivers hardware-enforced write protection via a dedicated, permanently configurable WP pin - a critical differentiator for safety-critical or tamper-evident applications requiring immutable configuration storage.

FAQ
What is the minimum operating voltage for the 24VL024T/MNY?
The 24VL024T/MNY operates down to 1.5V - verified across the full industrial temperature range (-20°C to +85°C). Below 1.8V, maximum I²C clock frequency is limited to 100 kHz to maintain timing margins. Internal voltage detection disables write operations below ~1.0V to prevent data corruption, ensuring safe operation even during brownout conditions.
Does the 24VL024T/MNY have hardware write protection?
Yes, the 24VL024T/MNY includes a dedicated WP (Write-Protect) pin that enables hardware-level lock of the entire 256-byte memory array when pulled high to VCC. This feature is intrinsic to the 24VL024 family and confirmed in the DS22130A datasheet - unlike register-based alternatives, it provides physical, power-cycle-persistent protection independent of firmware state.
How many devices can be connected on the same I²C bus using 24VL024T/MNY?
Up to eight 24VL024T/MNY devices can be cascaded on a single I²C bus using the A0, A1, and A2 address pins to configure unique 3-bit slave addresses (000b to 111b). Each device occupies 256 bytes, enabling up to 2 Kbytes (16 Kbits) of contiguous EEPROM space - verified in the Device Selection Table and Functional Description sections of DS22130A.
What is the page write capacity of the 24VL024T/MNY?
The 24VL024T/MNY supports page writes of up to 16 bytes per transaction - matching its internal page buffer size. Writes crossing physical page boundaries (every 16 bytes, starting at 00h, 10h, 20h, etc.) wrap within the current page rather than advancing to the next, requiring firmware to align multi-byte writes to page boundaries for predictable behavior.
Is the 24VL024T/MNY RoHS compliant and lead-free?
Yes, the 24VL024T/MNY is Pb-free and RoHS compliant per Microchip's official documentation (DS22130A, page 1). The TSSOP package uses matte tin (Sn) plating per JEDEC standard, and packaging markings include the "3e" Pb-free designation - confirmed in the Packaging Information section and Pb-free conversion notice on page 14.
