Product details
Overview
11LC160-I/MS from Microchip Technology is a 16 Kbit (2,048 × 8) serial EEPROM with UNI/O® single I/O bus interface, operating from 2.5V to 5.5V over -40°C to +85°C. It features 16-byte page write buffer, Schmitt-trigger SCIO input, output slope control, and 100 kbps max bit rate. Used for nonvolatile parameter storage in space-constrained industrial control modules.
For engineers reviewing the 11LC160-I/MS datasheet, 11LC160-I/MS pinout, 11LC160-I/MS application, or 11LC160-I/MS equivalent, key selection criteria include single-wire bus compatibility, industrial temperature support, 16-byte page write capability, standby current ≤1 µA, and MSOP-8 package footprint.
Technical Context
The 11LC160-I/MS 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 clock period during start header and re-synchronizes on each MAK edge.
It integrates a write-enable latch, STATUS register with WIP/WEL/BP bits, and hardware block protection (none/¼/½/all array). Write cycles are self-timed (≤10 ms), with automatic erase before programming and built-in power-on/off write protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density | 16 Kbit (2,048 × 8 organization) - supports up to 2 KB of persistent configuration data |
| 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 - reduces PCB routing to one signal plus VCC/VSS, ideal for pin-limited MCUs |
| Page Size | 16 bytes - enables efficient burst writes while avoiding cross-page boundary errors |
| Write Endurance | 1,000,000 cycles - supports frequent calibration or logging updates over product lifetime |
| Data Retention | >200 years at 85°C - ensures long-term reliability in unattended industrial deployments |
| Standby Current | ≤1 µA at 85°C - minimizes quiescent power in battery-backed or energy-harvesting systems |
| Package | 8-lead MSOP (MS) - 3 mm × 3 mm footprint with exposed pad option, suitable for automated SMT assembly |
Pinout & Package
8-lead MSOP package (MS suffix) with standard pinout: Pin 1 = VSS, Pin 2 = NC, Pin 3 = NC, Pin 4 = SCIO, Pin 5 = NC, Pin 6 = NC, Pin 7 = NC, Pin 8 = VCC. NC pins are no-connect and must remain unconnected per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSS (Pin 1) | Ground reference | Primary return path for all internal currents; requires low-impedance connection to system ground plane |
| SCIO (Pin 4) | Serial Clock/Data I/O | Bidirectional Manchester-encoded bus line; includes Schmitt trigger and slope control to suppress noise and ground bounce |
| VCC (Pin 8) | Supply voltage | Power input for core logic and EEPROM array; bypass capacitor (0.1 µF) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| UNI/O® single I/O interface | Reduces MCU GPIO usage to one pin for full read/write/control, simplifying firmware and layout in resource-constrained designs |
| 16-byte page write buffer | Enables atomic multi-byte writes without host-side timing constraints; eliminates need for external buffering logic |
| Status register with WIP/WEL bits | Allows real-time polling of write progress and write-enable state without halting other bus traffic |
| Hardware block write protection | Configurable via STATUS register to lock 0%, 25%, 50%, or 100% of memory - prevents accidental firmware corruption during field updates |
| Schmitt-trigger SCIO input | Provides ≥50 mV hysteresis (0.05×VCC) to reject EMI-induced glitches on noisy industrial PCBs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 11AA160-I/MS | Same density and package, but 1.8–5.5V VCC range and I-temp only (no E-temp option) | Required for ultra-low-voltage systems (e.g., coin-cell powered IoT nodes) where 2.5V minimum is unacceptable | Select 11AA160-I/MS only if supply drops below 2.5V; otherwise 11LC160-I/MS offers broader voltage margin |
| AT24C128B-MAUM-T | I²C interface (2-wire), 128 Kbit density, 1.7–5.5V, 8-lead UDFN package | Used where existing I²C infrastructure exists and higher capacity or faster random access is needed | Choose AT24C128B-MAUM-T when migrating from I²C-based designs; not drop-in due to protocol and pinout differences |
Compared with 11AA160-I/MS, the 11LC160-I/MS provides higher minimum VCC for improved noise immunity in electrically harsh environments; compared with AT24C128B-MAUM-T, it reduces signal routing complexity but trades off bandwidth and density for single-pin simplicity.

FAQ
What is the maximum bit rate supported by the 11LC160-I/MS UNI/O® interface?
The 11LC160-I/MS supports a maximum bit rate of 100 kbps, equivalent to a 100 kHz serial bus frequency. This is specified under AC characteristics with TE (bit period) ranging from 10 µs to 100 µs. The device uses Manchester encoding to embed clock and data on the SCIO line, and its re-synchronization circuitry tolerates up to ±0.50% frequency drift per byte and ±5% total deviation per command.
Does the 11LC160-I/MS require external pull-up resistors on the SCIO line?
No, the 11LC160-I/MS does not require external pull-up resistors on the SCIO line. Its internal output driver includes active slope control and current limiting, and the UNI/O® protocol relies on master-controlled bus timing rather than open-drain pull-up behavior. External termination is unnecessary unless specified by system-level EMI requirements beyond the device's built-in noise suppression.
How is write protection configured on the 11LC160-I/MS?
Write protection on the 11LC160-I/MS is configured via the STATUS register's BP0 and BP1 bits, set using the WRSR (Write Status Register) command. These nonvolatile bits enable four protection modes: no protection (00), protect 1/4 array (01), protect 1/2 array (10), or protect entire array (11). Protection applies to both byte and page writes and remains active after power cycles until explicitly changed.
What is the purpose of the NC pins on the 11LC160-I/MS MSOP package?
The NC pins (Pins 2, 3, 5, 6, 7) on the 11LC160-I/MS MSOP package are no-connect terminals and must remain unconnected in the PCB layout. They exist for package compatibility across the 11XX family and do not tie internally to any circuitry. Connecting them may cause undefined behavior or violate absolute maximum ratings, as confirmed in the DS22067J datasheet Pin Function Table and Package Types diagram.
Can the 11LC160-I/MS be used in automotive applications requiring AEC-Q200 qualification?
No, the 11LC160-I/MS is rated for Industrial temperature range (-40°C to +85°C) and is not AEC-Q200 qualified. While the 11LC160 part number is available in Automotive (E) grade (−40°C to +125°C), the /I/MS suffix explicitly denotes Industrial temperature and MSOP package - making it unsuitable for automotive under-hood or safety-critical applications requiring AEC-Q200 stress testing and traceability.
