Product details
Overview
11AA010T-I/SN from Microchip Technology Inc. is a 1 Kbit (128 × 8) serial EEPROM with UNI/O® single I/O bus interface, operating from 1.8V to 5.5V, featuring 16-byte page write buffer, Schmitt-trigger SCIO input, and 1 µA max standby current at I-temp (−40°C to +85°C). It is used in space-constrained embedded systems for nonvolatile parameter storage in sensor calibration, configuration registers, and firmware patch tracking.
For engineers reviewing the 11AA010T-I/SN datasheet, 11AA010T-I/SN pinout, 11AA010T-I/SN application, or 11AA010T-I/SN equivalent, key selection criteria include its 1.8V minimum VCC, UNI/O® bus compatibility with discrete GPIO, 1 M erase/write cycle endurance, >200-year data retention, and SOT-23-3 package footprint - critical for low-power, cost-sensitive, and PCB area-limited designs.
Technical Context
The 11AA010T-I/SN implements Manchester-encoded UNI/O® protocol over a single bidirectional SCIO line, eliminating need for separate clock and data lines. Its internal timing recovery circuitry synchronizes to master bit period (10–100 kHz), tolerating ±0.5% frequency drift per byte and ±0.06 UI edge jitter.
It integrates a status register with WIP and WEL bits, block write protection (BP0/BP1), and hardware write enable latch. Write operations are self-timed (max 10 ms), supported by 16-byte page buffer and automatic erase-before-write logic - all managed without external timing control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 Kbit (128 × 8 organization) - fits small configuration sets without memory waste |
| VCC Range | 1.8V to 5.5V - supports direct interfacing with 1.8V/3.3V/5V microcontrollers |
| Interface | Single I/O UNI/O® bus - reduces GPIO count and PCB routing complexity |
| Write Cycle Time | ≤10 ms (page or byte) - enables fast field updates without blocking host MCU |
| Endurance | 1,000,000 erase/write cycles - suitable for frequent recalibration or logging |
| Data Retention | >200 years at +85°C - ensures long-term reliability in industrial deployments |
| Standby Current | ≤1 µA (I-temp) - minimizes battery drain in always-on sensor nodes |
Pinout & Package
11AA010T-I/SN uses 3-lead SOT-23 package (SN suffix), with top-side marking "AA010T" and pin 1 (SCIO) identified by dot. Pinout is unidirectional: SCIO handles bidirectional Manchester-encoded serial communication; VCC supplies power; VSS is ground. No NC pins present in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCIO | Serial Clock/Data I/O | Bidirectional Manchester-encoded bus line - requires no external pull-up; includes Schmitt trigger and slope control |
| VCC | Supply Voltage | 1.8–5.5V input - powers EEPROM core and I/O driver; supports brown-out tolerant operation |
| VSS | Ground | Reference return path for SCIO and internal logic - must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| UNI/O® Serial Interface | Single-pin bus eliminates clock/data skew and simplifies layout on dense PCBs |
| Page Write Buffer | 16-byte buffer enables burst writes without host intervention between bytes |
| Status Register Access | Real-time WIP/WEL monitoring via RDSR command - avoids polling delays |
| Block Write Protection | Configurable BP0/BP1 bits protect 0%, 25%, 50%, or 100% of memory - prevents accidental overwrite |
| Noise Immunity | Schmitt-trigger SCIO input + 50 ns spike suppression - rejects EMI in motor-driven or switching environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 11LC010T-I/SN | Requires ≥2.5V VCC; identical density, page size, and UNI/O® protocol | Not suitable for 1.8V systems; otherwise drop-in compatible in 3.3V/5V designs | Select when higher VCC margin is acceptable and 1.8V operation is unnecessary |
| AT24C01D-SSHM-T | I²C interface (2-wire), 1.7–5.5V, 1 Kbit, 8-lead SOIC package | Requires two GPIOs (SCL/SDA); lacks UNI/O® single-pin advantage and Schmitt-trigger noise immunity | Choose when existing I²C infrastructure exists and board space permits larger package |
Compared with 11AA010T-I/SN, the 11LC010T-I/SN offers identical functionality at higher voltage, while the AT24C01D-SSHM-T trades UNI/O® simplicity for broader ecosystem support - making 11AA010T-I/SN optimal for ultra-low-pin-count, 1.8V–5.5V, noise-prone applications.

FAQ
What is the minimum operating voltage for the 11AA010T-I/SN?
The 11AA010T-I/SN operates down to 1.8V across its full industrial temperature range (−40°C to +85°C), enabling direct integration with 1.8V microcontrollers and ultra-low-power systems where higher-voltage EEPROMs would require level-shifting or regulator overhead.
How does the UNI/O® interface of the 11AA010T-I/SN differ from standard I²C or SPI?
The 11AA010T-I/SN uses Manchester-encoded serial communication over a single bidirectional SCIO line, eliminating separate clock and data lines required by I²C or SPI. This reduces GPIO usage, PCB routing complexity, and susceptibility to clock/data skew - ideal for designs with minimal available pins.
Can the 11AA010T-I/SN be used in automotive applications?
The 11AA010T-I/SN is rated for industrial temperature only (−40°C to +85°C) and lacks AEC-Q200 qualification. For automotive use, Microchip's 11LC010T-E/SN (−40°C to +125°C, AEC-Q200 qualified) is the designated alternative - the 11AA010T-I/SN is not recommended for under-hood or safety-critical vehicle systems.
What is the purpose of the STATUS register in the 11AA010T-I/SN?
The STATUS register in the 11AA010T-I/SN provides real-time visibility into device state: the WIP bit indicates active write cycles, the WEL bit shows write-enable latch status, and BP0/BP1 bits reflect configured block protection. It can be read at any time - even during writes - enabling efficient host polling without command interruption.
Does the 11AA010T-I/SN support hardware write protection?
Yes, the 11AA010T-I/SN includes dual-layer hardware write protection: built-in power-on/off data protection circuitry prevents spurious writes during voltage transitions, and configurable block protection (via BP0/BP1 bits) allows locking 0%, 25%, 50%, or 100% of the memory array - ensuring critical configuration data remains immutable.
