Product details
Overview
11LC010-E/P 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 and sensor calibration storage.
For engineers reviewing the 11LC010-E/P datasheet, 11LC010-E/P pinout, 11LC010-E/P application, or 11LC010-E/P equivalent, this device delivers deterministic Manchester-encoded timing at up to 100 kHz, supports self-timed writes with 5–10 ms cycle time, and provides nonvolatile storage with 1 million endurance cycles and >200-year data retention in compact 8-lead PDIP packaging.
Technical Context
The 11LC010-E/P implements a Manchester-encoded UNI/O® bus protocol over a single SCIO line, extracting clock and data from one bidirectional signal using internal re-synchronization circuitry tolerant to ±0.5% frequency drift per byte and ±0.06 UI edge jitter. It uses an 8-bit instruction register and supports command-based read/write/erase operations with MAK/NoMAK acknowledge sequencing.
Internally, it integrates a current-limited slope-controlled SCIO driver, HV generator for EEPROM programming, 128 × 8-bit memory array with page latches, and a STATUS register with WIP, WEL, BP0, and BP1 bits. Block write protection covers none, 1/4, 1/2, or all of the array, enforced by hardware and STATUS register configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 1 Kbit (128 × 8 organization) - fixed memory map enabling predictable address pointer rollover during sequential reads. |
| VCC Range | 2.5 V to 5.5 V - supports direct connection to 3.3 V and 5 V microcontroller I/O without level shifting. |
| Bus Interface | UNI/O® single I/O (SCIO) with Manchester encoding - eliminates need for separate clock line and reduces PCB routing complexity. |
| Max Bit Rate | 100 kbps (equivalent to 100 kHz clock) - defines maximum sustained throughput for firmware updates or sensor log writes. |
| Write Cycle Time | 5 ms (byte) / 10 ms (page) - determines minimum time between successive write commands; page writes complete faster per byte than individual byte writes. |
| Endurance | 1,000,000 erase/write cycles - ensures reliable operation over full vehicle lifetime in automotive recalibration applications. |
| Data Retention | >200 years at 85°C - guarantees long-term validity of stored calibration coefficients without refresh. |
| Temp Range | -40°C to +125°C (Automotive E-grade) - qualified for under-hood and powertrain control unit environments. |
Pinout & Package
11LC010-E/P is housed in an 8-lead PDIP package (package code "P"), with lead finish Pb-free and RoHS compliant. Pin 1 is VSS (ground), Pin 4 is NC (no connect), Pin 5 is VCC (supply voltage), Pin 8 is SCIO (serial clock/data I/O), and Pins 2, 3, 6, 7 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS (Pin 1) | Ground reference | Primary return path for SCIO signaling and internal logic; must be low-impedance to suppress ground bounce during output transitions. |
| NC (Pins 2, 3, 6, 7) | No connect | Unused pins; must remain unconnected per design - no internal bonding or functionality. |
| VCC (Pin 5) | Supply voltage | Power source for EEPROM core and interface logic; requires local 0.1 µF decoupling capacitor near pin. |
| NC (Pin 4) | No connect | Reserved pad with no internal connection; electrically isolated from die. |
| SCIO (Pin 8) | Serial Clock/Data I/O | Bidirectional Manchester-encoded bus line - carries both clock and data; includes Schmitt trigger input and slope-controlled output to reduce EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Single I/O UNI/O® bus | Reduces MCU GPIO usage to one pin while maintaining deterministic timing via embedded clock recovery - ideal for space-constrained automotive modules. |
| Schmitt-trigger SCIO input | Provides 50 mV hysteresis (0.05 × VCC) to reject noise on long traces or noisy chassis-grounded systems. |
| Output slope control | Actively limits dV/dt on SCIO to eliminate ground bounce during high-speed transitions - critical for stable communication in mixed-signal ECUs. |
| Page-write buffer (16 bytes) | Enables burst writes within a 16-byte physical page boundary, reducing total write time vs. byte-by-byte programming. |
| Status register (WIP/WEL/BP) | Allows real-time monitoring of write progress and protection state without halting host MCU execution - simplifies robust firmware error handling. |
| Block write protection | Hardware-enforced protection of 0%, 25%, 50%, or 100% of memory via BP0/BP1 bits - prevents accidental overwrites of critical calibration data. |
Applications
| Engine Control Unit (ECU) Calibration Storage | Body Control Module (BCM) Configuration |

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/P | Lower VCC min (1.8 V), Industrial temp only (-40°C to +85°C), same density and UNI/O® interface. | Not qualified for under-hood or powertrain use; suitable for cabin electronics or industrial controls where extended temperature is not required. | Select 11AA010-I/P only if system operates down to 1.8 V and does not require automotive qualification. |
| 24LC01B-I/P | I²C interface (2-wire), 1 Kbit, 2.5–5.5 V, same PDIP-8 package but different pinout (SCL/SDA/VSS/VCC). | Requires two dedicated MCU pins and pull-up resistors; lacks UNI/O®'s single-wire advantage and built-in slope control. | Choose 24LC01B-I/P only if existing I²C infrastructure exists and GPIO count is not constrained. |
Compared with 11LC010-E/P, 11AA010-I/P offers wider voltage flexibility but lacks automotive temperature rating, while 24LC01B-I/P trades pin count simplicity for standard I²C compatibility - neither is pin-compatible, and both require layout changes due to differing pin functions and bus protocols.

FAQ
What is the UNI/O® bus interface used by the 11LC010-E/P?
The 11LC010-E/P uses Microchip's patented UNI/O® bus, a single-wire, Manchester-encoded serial interface where clock and data are embedded in one SCIO signal. This eliminates the need for a separate clock line, reduces MCU pin count, and enables deterministic timing recovery by the slave device - a key differentiator from I²C or SPI interfaces used in the 11LC010-E/P family.
Does the 11LC010-E/P support page writes, and what is the page size?
Yes, the 11LC010-E/P supports page writes with a 16-byte buffer. Each physical page spans 16 consecutive addresses (e.g., 0x00–0x0F), and writes crossing a page boundary wrap around within that page. The 11LC010-E/P requires proper firmware alignment to avoid unintended overwrites - page writes complete in 10 ms, improving efficiency over individual byte writes.
How does the STATUS register in the 11LC010-E/P assist in system design?
The 11LC010-E/P STATUS register contains WIP (Write-In-Progress), WEL (Write Enable Latch), and BP0/BP1 (Block Protection) bits. It enables real-time polling of write status without halting MCU execution, supports safe write enable/disable sequencing, and allows hardware-level memory partitioning - critical for fail-safe automotive firmware that must verify write completion before proceeding.
What is the maximum operating temperature range for the 11LC010-E/P?
The 11LC010-E/P is rated for -40°C to +125°C (Automotive E-grade), fully qualified for under-hood and powertrain applications. This exceeds the Industrial grade (-40°C to +85°C) of the 11AA010 variant and ensures reliable operation in high-temperature ECU environments where ambient heat and self-heating combine.
Can the 11LC010-E/P be used with 1.8 V microcontrollers?
No, the 11LC010-E/P requires a minimum VCC of 2.5 V and is not specified for 1.8 V operation. For 1.8 V systems, Microchip offers the 11AA010-I/P variant, which shares the same UNI/O® interface and 1 Kbit density but is limited to Industrial temperature range. Using 11LC010-E/P below 2.5 V may result in unreliable communication or write failures.
