Product details
Overview
11LC010T-I/MNY from Microchip Technology is a 1 Kbit (128 × 8) serial EEPROM with UNI/O® single I/O bus interface, operating from 2.5V to 5.5V, featuring 16-byte page write buffer, Schmitt-trigger SCIO input, and 1 µA max standby current over –40°C to +85°C industrial temperature range. It is used for parameter storage in space-constrained embedded systems such as sensor calibration modules and power supply configuration.
For engineers reviewing the 11LC010T-I/MNY datasheet, 11LC010T-I/MNY pinout, 11LC010T-I/MNY application, or 11LC010T-I/MNY equivalent, key selection criteria include UNI/O® bus compatibility, 3-lead SOT-23 package footprint, 100 kbps bit rate, write protection granularity, and endurance of 1 million cycles - all critical for low-pin-count, low-power firmware update and configuration retention designs.
Technical Context
The 11LC010T-I/MNY implements Manchester-encoded UNI/O® protocol on a single bidirectional SCIO line, eliminating need for separate clock and data lines. Its internal timing recovery circuitry synchronizes to master-generated bit periods and tolerates ±0.50% frequency drift per byte and ±0.06 UI edge jitter.
It integrates a 16-byte page write buffer, STATUS register with WIP/WEL/BP bits, and hardware block write protection (none/¼/½/all array). Write operations are self-timed with 5–10 ms cycle time and include auto-erase; read operations support random and current-address modes with automatic address pointer increment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 Kbit (128 × 8 organization) - fixed memory map enabling deterministic addressing in resource-limited microcontrollers. |
| VCC Range | 2.5V to 5.5V - compatible with standard 3.3V and 5V logic domains without level-shifting. |
| Interface | Single I/O UNI/O® bus (SCIO) - reduces PCB routing complexity and pin count vs. I²C/SPI. |
| Max Bit Rate | 100 kbps (equivalent to 100 kHz clock) - supports fast configuration reads while maintaining noise immunity via Manchester encoding. |
| Write Endurance | 1,000,000 erase/write cycles - ensures long-term reliability in field-updatable calibration or logging applications. |
| Data Retention | >200 years - guarantees nonvolatile storage integrity across product lifecycle without refresh. |
| Standby Current | 1 µA max (I-temp) - enables battery-backed operation in always-on IoT edge nodes. |
| Page Size | 16 bytes - optimizes write efficiency for small configuration blocks while preventing cross-page wrap errors. |
Pinout & Package
11LC010T-I/MNY is packaged in 3-lead SOT-23 (MNY suffix), with SCIO serving as bidirectional serial clock/data I/O, VSS as ground reference, and VCC as supply voltage. No NC pins are present in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SCIO) | Serial Clock/Data I/O | Bidirectional Manchester-encoded signal carrying clock and data; includes Schmitt trigger and slope control to suppress noise and ground bounce. |
| 2 (VSS) | Ground | Reference return path for all internal circuitry; must be low-impedance to maintain timing accuracy during high-speed bus transitions. |
| 3 (VCC) | Supply Voltage | Primary power input (2.5–5.5V); powers EEPROM core, UNI/O® interface logic, and HV generator for write/erase operations. |
Key Features
| Feature | Design Value |
|---|---|
| UNI/O® Serial Interface | Single-wire bus eliminates dedicated clock line and simplifies host MCU GPIO usage - ideal for pin-starved 8-bit microcontrollers. |
| Page Write Buffer | 16-byte buffer enables burst writes within one command, reducing bus overhead and minimizing total write time vs. byte-by-byte programming. |
| Status Register Access | Read-only WIP and WEL bits allow real-time monitoring of write progress and protection state without halting system operation. |
| Block Write Protection | BP0/BP1 bits enable hardware-level protection of 0%, 25%, 50%, or 100% of memory - prevents accidental overwrite of critical firmware parameters. |
| Schmitt Trigger Input | Hysteresis ≥0.05×VCC rejects EMI-induced glitches on SCIO, ensuring robust communication in electrically noisy industrial environments. |
| Self-Timed Write Cycle | Internal timing eliminates need for external wait-state management; host only polls WIP bit to determine completion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 11AA010T-I/MNY | Wider VCC range (1.8–5.5V); identical density, page size, UNI/O® interface, and SOT-23 package. | Supports 1.8V systems (e.g., ultra-low-power MCUs); not rated for automotive temp range. | Select 11AA010T-I/MNY when operating below 2.5V; otherwise 11LC010T-I/MNY offers tighter VCC min spec and same industrial temp rating. |
| 24AA01T-I/OT | I²C interface (2-wire), 1 Kbit, SOIC-8 package; no UNI/O®, higher standby current (5 µA), different pinout. | Requires two dedicated I²C lines and pull-up resistors; incompatible with UNI/O®-only host firmware. | Choose 24AA01T-I/OT only if existing design uses I²C infrastructure and board layout cannot accommodate SOT-23 footprint change. |
Compared with 11AA010T-I/MNY, the 11LC010T-I/MNY trades 1.8V operation for stricter 2.5V minimum - improving noise margin in noisy 3.3V/5V systems. Against 24AA01T-I/OT, it delivers 5× lower standby current and 3-pin footprint reduction but requires UNI/O®-capable firmware.

FAQ
What is the UNI/O® interface used by the 11LC010T-I/MNY?
The 11LC010T-I/MNY uses Microchip's patented UNI/O® bus - a single-wire, Manchester-encoded serial interface that combines clock and data on the SCIO pin. This eliminates the need for separate clock and data lines, reducing host MCU pin count and PCB routing complexity. The 11LC010T-I/MNY supports up to 100 kbps bit rate and includes built-in synchronization recovery for frequency drift and edge jitter tolerance.
Does the 11LC010T-I/MNY support hardware write protection?
Yes, the 11LC010T-I/MNY includes hardware block write protection controlled by BP0 and BP1 bits in its STATUS register. These nonvolatile bits can be programmed via the WRSR instruction to protect none, 1/4, 1/2, or all of the 128-byte memory array. This feature prevents accidental overwrites of critical calibration or configuration data, enhancing system robustness in field-deployed equipment.
What is the maximum write endurance and data retention of the 11LC010T-I/MNY?
The 11LC010T-I/MNY guarantees 1,000,000 erase/write cycles per memory location and greater than 200 years of data retention at +85°C. These specifications are validated under industrial temperature conditions (–40°C to +85°C) and apply across the full VCC range of 2.5V to 5.5V, making the 11LC010T-I/MNY suitable for long-life embedded applications with infrequent but mission-critical updates.
Can the 11LC010T-I/MNY operate from a 1.8V supply?
No, the 11LC010T-I/MNY requires a minimum VCC of 2.5V and operates from 2.5V to 5.5V. For 1.8V operation, Microchip offers the pin-compatible 11AA010T-I/MNY, which shares identical density, page size, UNI/O® interface, and SOT-23 package but extends VCC down to 1.8V. The 11LC010T-I/MNY is optimized for higher-noise-margin 3.3V/5V systems.
What package type does the 11LC010T-I/MNY use, and how many pins does it have?
The 11LC010T-I/MNY uses a 3-lead SOT-23 package (MNY suffix), with leads assigned as SCIO (pin 1), VSS (pin 2), and VCC (pin 3). This ultra-compact surface-mount package measures 2.9 mm × 1.6 mm × 1.1 mm and requires no NC pins, enabling minimal PCB footprint in space-constrained applications such as wearable medical devices and miniaturized industrial sensors.
