Product details
Overview
24AA00T-I/MNY from Microchip Technology Inc. is a 128-bit (16 × 8) I²C-compatible serial EEPROM designed for low-power, space-constrained applications requiring nonvolatile storage of calibration data, device IDs, or manufacturing traceability. It operates from 1.8 V to 5.5 V, draws only 500 µA typical read current and 100 nA typical standby current, and supports 100 kHz/400 kHz clock rates in industrial temperature range (–40°C to +85°C).
For engineers reviewing the 24AA00T-I/MNY datasheet, 24AA00T-I/MNY pinout, 24AA00T-I/MNY application, or 24AA00T-I/MNY equivalent, key selection considerations include its ultra-low-voltage operation down to 1.8 V, 5-pin SOT-23 package footprint, Schmitt-trigger noise immunity on SDA/SCL, self-timed 3 ms write cycle, and >1 million endurance cycles with >200-year data retention.
Technical Context
The 24AA00T-I/MNY implements a true 2-wire I²C slave interface with fixed 7-bit address (1010xxx), no external address pins, and automatic internal address pointer incrementation during sequential reads. Its architecture includes integrated HV generator for EEPROM programming, Schmitt-trigger inputs with 50 ns spike suppression, and output slope control to minimize ground bounce.
It uses a single VCC-supplied charge pump for erase/write operations and features a VCC threshold detector that disables write logic below 1.5 V. The device does not generate ACK during internal write cycles-enabling reliable acknowledge polling-and supports byte, random, and sequential read modes without requiring external timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 bits (16 words × 8 bits); sufficient for small configuration or ID storage without over-provisioning PCB area. |
| Supply voltage | 1.8 V to 5.5 V; enables direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V microcontrollers without level shifters. |
| Interface | I²C-compatible 2-wire bus; requires only SDA and SCL lines plus pull-ups-reducing routing complexity and pin count. |
| Write time | 3 ms typical page write; deterministic self-timed cycle eliminates need for software delay or status polling overhead. |
| Endurance | 1 million erase/write cycles; supports frequent field updates such as logging or calibration adjustment in deployed systems. |
| Data retention | 200+ years at +85°C; ensures long-term reliability for products with multi-decade service life or archival requirements. |
| ESD protection | >4 kV HBM; provides robustness against handling and board-level ESD events without external protection diodes. |
Pinout & Package
24AA00T-I/MNY is housed in a Pb-free, RoHS-compliant 5-lead SOT-23 package (JEDEC TO-236AB), measuring 2.90 mm × 1.30 mm × 1.00 mm. The exposed pad is not electrically connected and may be left floating or grounded for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCL | Serial Clock input | Asynchronous master-controlled clock line; Schmitt-triggered with 50 ns noise filtering-tolerates noisy environments without external RC filters. |
| SDA | Serial Data bidirectional I/O | Open-drain I²C bus line requiring external pull-up; supports shared-bus arbitration and multi-master operation. |
| VSS | Ground reference | Primary return path for all internal circuitry; must be low-impedance to ensure stable EEPROM programming voltage generation. |
| VCC | Power supply input | Supplies both logic and charge-pump circuitry; internal VCC monitor disables writes below 1.5 V to prevent corruption. |
| NC | No-connect terminal | Internally unconnected; electrically isolated-no routing, termination, or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.8 V-enables use in battery-powered or energy-harvesting systems where rail voltage sags below 2.5 V. |
| Ultra-low standby current | 100 nA typical-minimizes quiescent power draw in always-on IoT sensors or sleep-mode embedded controllers. |
| Bus noise immunity | Schmitt-trigger inputs + 50 ns input filter-eliminates false Start/Stop detection on electrically noisy industrial or automotive PCBs. |
| Write cycle reliability | Self-timed erase/write with VCC brown-out protection-guarantees data integrity even during power interruption or undervoltage events. |
| Small-footprint packaging | 5-pin SOT-23 (2.9 × 1.3 mm)-fits in tight spaces where 8-pin SOIC or TSSOP would exceed layout constraints. |
Applications
| Smart Sensor Calibration | Industrial PLC Configuration |
|---|---|
|
Use Scenario: Storing factory-calibrated sensor offset/gain coefficients and temperature compensation tables in MEMS pressure or humidity sensors. IC Role / Device Role / Timing Role: Nonvolatile configuration storage accessed once at power-up via I²C by host MCU; no real-time timing constraints.

Use Value: Allows single hardware SKU to support multiple SKUs via software-defined features-simplifies inventory and reduces production complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 24LC00T-I/MNY | Requires minimum 2.5 V VCC; otherwise identical pinout, timing, and memory organization. | Not suitable for 1.8 V systems; acceptable where 3.3 V or 5 V rails are guaranteed and lower standby current is not critical. | Select when system VCC never drops below 2.5 V and legacy 24LC00 qualification is required. |
| AT24C01A-PU | 1 Kbit capacity (128 × 8), same 5-pin SOT-23 package, but requires 1.7–5.5 V and lacks factory-programmable option. | Provides 8× more memory for extended configuration sets; no factory programming service available from Microchip. | Choose when future scalability or larger parameter tables are anticipated, and factory pre-programming is unnecessary. |
Compared with 24AA00T-I/MNY, the 24LC00T-I/MNY trades 1.8 V compatibility for marginally higher minimum supply, while the AT24C01A-PU offers greater density in identical footprint at the cost of losing Microchip's factory programming capability and slightly higher typical standby current (300 nA vs. 100 nA).

FAQ
What is the minimum operating voltage for the 24AA00T-I/MNY?
The 24AA00T-I/MNY operates down to 1.8 V, making it compatible with modern low-voltage microcontrollers and battery-powered devices. Its internal charge pump and VCC threshold detector disable write operations below 1.5 V to prevent data corruption-ensuring safe operation across the full 1.8 V to 5.5 V range specified in the 24AA00T-I/MNY datasheet.
Does the 24AA00T-I/MNY support standard I²C addressing?
Yes, the 24AA00T-I/MNY uses a fixed 7-bit I²C slave address of 1010xxx (where xxx are "don't care" bits), resulting in eight possible addresses (0x50–0x57). It does not support external address pins, so multiple 24AA00T-I/MNY devices on the same bus require different base addresses or external multiplexing-confirmed in the 24AA00T-I/MNY functional description section.
How is write completion detected for the 24AA00T-I/MNY?
Write completion is detected using acknowledge polling: after issuing a Stop condition to initiate the internal 3 ms write cycle, the host sends a repeated Start + control byte (R/W = 0); the 24AA00T-I/MNY responds with an ACK only when the write is complete. This method avoids fixed delays and maximizes bus efficiency-documented in Section 7.0 of the 24AA00T-I/MNY datasheet.
What package type is used for the 24AA00T-I/MNY?
The 24AA00T-I/MNY is supplied in a 5-lead SOT-23 package (JEDEC TO-236AB), with pinout SCL–SDA–VSS–NC–VCC. This compact 2.90 mm × 1.30 mm footprint matches industry-standard land patterns and supports automated placement-verified in the Pin Function Table and Package Marking Information sections of the 24AA00T-I/MNY datasheet.
Can the 24AA00T-I/MNY be factory-programmed before shipment?
Yes, factory programming is explicitly supported for the 24AA00T-I/MNY per the Features section of its datasheet. Microchip offers pre-programming of calibration data, serial numbers, or custom bit patterns during wafer sort or final test-enabling secure, traceable, and ready-to-use deployment without post-manufacture programming steps.
