Product details
Overview
11LC010-E/SN 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 grade), featuring 16-byte page write buffer, 1 µA max standby current, and built-in block write protection for 0%, 25%, 50%, or 100% of memory - deployed in automotive body control modules for calibration storage.
For engineers reviewing the 11LC010-E/SN datasheet, 11LC010-E/SN pinout, 11LC010-E/SN application, or 11LC010-E/SN equivalent, key selection criteria include UNI/O® bus compatibility, automotive temperature range validation, 16-byte page buffer utilization, VCC voltage margin (2.5–5.5V), and SCIO pin timing compliance with ±0.06 UI input jitter tolerance.
Technical Context
The 11LC010-E/SN implements Manchester-encoded UNI/O® protocol over a single bidirectional SCIO line, eliminating need for separate clock and data lines. Its internal re-synchronization circuitry tolerates ±0.50% bus frequency drift per byte and ±5% total deviation per command, enabling robust operation in electrically noisy automotive environments.
It integrates Schmitt-trigger inputs on SCIO for noise immunity, slope-controlled output driver to suppress ground bounce, and a status register with WIP and WEL bits accessible via RDSR instruction - all managed by an internal state machine that transitions between Standby, Active, and Idle modes based on header detection, ACK sequences, and error conditions.

Pinout & Package
11LC010-E/SN is packaged in 3-lead SOT-23 (SN suffix), with SCIO, VCC, and VSS terminals. No NC pins - minimal footprint ideal for space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCIO | Serial Clock/Data I/O | Single bidirectional line carrying Manchester-encoded clock+data; requires external pull-up; supports master-initiated standby pulse and header synchronization |
| VCC | Supply Voltage | Power input (2.5–5.5V); internally regulated for EEPROM core; decoupling capacitor required within 10 mm |
| VSS | Ground Reference | Return path for all internal circuits; must be connected directly to system ground plane with low-inductance trace |
Key Features
| Feature | Design Value |
|---|---|
| UNI/O® Serial Interface | Single-pin bus reduces MCU pin count and PCB routing complexity vs. I²C/SPI; eliminates clock skew and bus arbitration overhead |
| Self-Timed Write Cycle | No external timing control needed; internal HV generator manages erase/write; Twc ≤10 ms per page ensures deterministic firmware update latency |
| Block Write Protection | BP0/BP1 bits in STATUS register allow hardware-level locking of memory segments - prevents accidental overwrite of critical calibration tables |
| Schmitt Trigger Inputs | Hysteresis ≥0.05×VCC on SCIO rejects <50 ns noise spikes - essential for reliable communication in 12V automotive harness environments |
| Output Slope Control | Controlled edge rate minimizes ground bounce during SCIO transitions - avoids false triggering of adjacent digital inputs on shared PCB planes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 11AA010-I/SN | 1.8–5.5V supply range; Industrial temp only (-40°C to +85°C); same 128×8 density and UNI/O® interface | Not qualified for under-hood use; suitable for cabin infotainment or dashboard displays | Select only if system operates below 2.5V or does not require automotive temperature certification |
| AT24C01D-SSHM-T | I²C interface (2-wire), 1Kbit, 1.7–5.5V, -40°C to +85°C; no UNI/O® support; different addressing and timing | Requires dedicated I²C peripheral; incompatible with existing UNI/O® firmware stack | Choose only when migrating from UNI/O® to standardized I²C infrastructure and redesigning driver layer |
Compared with 11AA010-I/SN, the 11LC010-E/SN provides guaranteed operation up to +125°C and higher VCC minimum (2.5V), making it the sole choice for engine bay modules; versus AT24C01D-SSHM-T, it retains pin- and protocol-level compatibility with legacy UNI/O® designs while delivering automotive qualification.

FAQ
What is the UNI/O® bus interface used by the 11LC010-E/SN?
The 11LC010-E/SN uses Microchip's patented UNI/O® bus - a single-wire, Manchester-encoded serial interface where clock and data share the SCIO pin. It eliminates separate clock lines, supports master-initiated synchronization via start headers, and tolerates ±0.06 UI input jitter. This architecture reduces MCU pin count and PCB routing complexity compared to I²C or SPI, and is fully implemented in the 11LC010-E/SN without external components.
Does the 11LC010-E/SN support write protection, and how is it configured?
Yes, the 11LC010-E/SN supports hardware block write protection via BP0 and BP1 bits in its STATUS register. These nonvolatile bits - set using the WRSR instruction - enable locking of 0%, 25%, 50%, or 100% of the 128-byte array. Protection is enforced at the silicon level: attempts to write to locked blocks return NoSAK and leave memory unchanged. This feature is critical for safeguarding calibration data in automotive applications where accidental firmware writes must be prevented.
What is the maximum write speed and page size of the 11LC010-E/SN?
The 11LC010-E/SN has a fixed page size of 16 bytes and supports page-write operations - allowing up to 16 bytes to be loaded into the internal buffer and committed atomically. The maximum write cycle time is 10 ms for a full page (TWC). Bus speed is limited to 100 kbps (100 kHz equivalent), meaning a full 16-byte page write requires ~1.3 ms of bus time plus up to 10 ms internal programming. This design balances speed, reliability, and power efficiency for automotive parameter storage.
Can the 11LC010-E/SN operate at 1.8V?
No, the 11LC010-E/SN is specified for 2.5V to 5.5V operation only. It is not rated for 1.8V supply - attempting to power it below 2.5V may result in unreliable read/write behavior or failure to exit standby mode. For 1.8V systems, Microchip offers the pin-compatible 11AA010-I/SN variant, but that part is Industrial-grade only (-40°C to +85°C) and lacks Automotive (E-grade) qualification. The 11LC010-E/SN's 2.5V minimum ensures robust performance in automotive 12V-derived 3.3V or 5V domains.
How does the 11LC010-E/SN handle power loss during a write operation?
The 11LC010-E/SN incorporates built-in power-loss protection: its internal write cycle is self-timed and requires no external strobe, and the device monitors VCC during programming. If VCC drops below the functional threshold during a write, the internal state machine aborts the operation and preserves pre-write data integrity. Additionally, the write-enable latch (WEL) resets on power-up, preventing unintended writes after brown-out recovery - a key safety feature confirmed in DS22067J-page 13 for the 11LC010-E/SN.
