Product details
Overview
11LC010T-E/MNY from Microchip Technology Inc. is a 1 Kbit (128 × 8) serial EEPROM with UNI/O® single-I/O bus interface, operating from 2.5V to 5.5V across -40°C to +125°C (Automotive E-temp), featuring 16-byte page write buffer, Schmitt-trigger SCIO input, and built-in write protection for automotive body control modules.
For engineers reviewing the 11LC010T-E/MNY datasheet, 11LC010T-E/MNY pinout, 11LC010T-E/MNY application, or 11LC010T-E/MNY equivalent, key selection considerations include its UNI/O® bus timing tolerance (±0.5% frequency drift per byte), 100 kbps max bit rate, standby current ≤1 µA at I-temp, page-write endurance of 1 million cycles, and automotive-grade temperature compliance.
Technical Context
The 11LC010T-E/MNY implements Manchester-encoded serial communication over a single SCIO line, extracting clock and data from one signal stream. It uses internal re-synchronization circuitry to tolerate edge jitter (±0.06 UI) and frequency drift (±0.5% per byte), enabling robust operation in electrically noisy automotive environments.
Its architecture includes a status register with WIP and WEL bits, block write protection (BP0/BP1) for 0%, 25%, 50%, or 100% array protection, and slope-controlled output to suppress ground bounce. The device supports self-timed write cycles with auto-erase and requires explicit WREN/WRDI control before write operations.

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 | 1.8–5.5V VCC range; Industrial temp only (-40°C to +85°C); same 1K density and UNI/O® interface | Not qualified for under-hood or powertrain use; limited to cabin modules and infotainment | Select when lower-voltage operation (1.8V) is required and automotive temperature grade is unnecessary |
| AT24C01C-SSHM-T | I²C interface (2-wire), 1K density, 1.7–5.5V, -40°C to +85°C; no UNI/O® or E-temp rating | Lacks automotive qualification and single-wire simplicity; requires two dedicated MCU pins | Choose only if existing I²C infrastructure exists and E-temp compliance is not mandated |
Compared with 11AA010T-I/MNY, the 11LC010T-E/MNY provides mandatory automotive temperature support and higher minimum VCC, while AT24C01C-SSHM-T trades UNI/O® pin economy for broader ecosystem compatibility but forfeits AEC-Q100 alignment and noise-hardened timing recovery.

FAQ
What is the UNI/O® interface used by the 11LC010T-E/MNY?
The 11LC010T-E/MNY uses Microchip's patented UNI/O® serial bus, which combines clock and data onto a single SCIO line using Manchester encoding. This eliminates the need for separate clock and data lines, reducing MCU pin usage and PCB routing complexity. The 11LC010T-E/MNY recovers timing internally and tolerates ±0.5% frequency drift per byte, making it robust in electrically noisy automotive environments.
Does the 11LC010T-E/MNY support write protection, and how is it configured?
Yes, the 11LC010T-E/MNY supports configurable block write protection via BP0 and BP1 bits in its STATUS register. These bits-set using the WRSR command-allow protection of 0%, 25%, 50%, or 100% of the memory array. Protection is nonvolatile and persists across power cycles. Additionally, hardware write enable latch (WEL) and power-on write protection prevent unintended writes during power transitions.
What is the maximum operating temperature range for the 11LC010T-E/MNY?
The 11LC010T-E/MNY is rated for -40°C to +125°C (Automotive E-temp grade), fully qualified for under-hood and powertrain applications. This exceeds standard industrial grade (-40°C to +85°C) and aligns with AEC-Q100 stress test requirements. Its electrical characteristics-including 1 µA max standby current and 5 mA write current-are specified across this full range.
Can the 11LC010T-E/MNY be used with 1.8V microcontrollers?
No, the 11LC010T-E/MNY requires a minimum VCC of 2.5V and operates from 2.5V to 5.5V. For 1.8V systems, Microchip offers the pin-compatible 11AA010T-I/MNY, which supports 1.8–5.5V but is rated only for Industrial temperature (-40°C to +85°C). The 11LC010T-E/MNY's higher VCC threshold ensures stable UNI/O® timing and noise margin in automotive 3.3V/5V domains.
How many write cycles can the 11LC010T-E/MNY endure, and what is its data retention?
The 11LC010T-E/MNY guarantees 1,000,000 erase/write cycles per memory location and >200 years of data retention at 85°C. These specifications are validated per JEDEC standards and apply across its full automotive temperature range. Endurance is measured at 25°C and 5.5V, with retention extrapolated using Arrhenius modeling-ensuring long-term reliability in safety-critical automotive storage applications.
