Product details
Overview
11LC160T-E/MNY from Microchip Technology Inc. is a 16 Kbit (2,048 × 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, Schmitt-trigger SCIO input, and built-in write protection for automotive body control modules and engine management sensors.
For engineers reviewing the 11LC160T-E/MNY datasheet, 11LC160T-E/MNY pinout, 11LC160T-E/MNY application, or 11LC160T-E/MNY equivalent, this device delivers deterministic Manchester-encoded timing, 100 kbps max bit rate, 1 µA standby current, 1M endurance cycles, and block-level write protection - critical for functional safety–aware firmware storage in harsh-temperature embedded systems.
Technical Context
The 11LC160T-E/MNY implements a Manchester-encoded UNI/O® bus protocol using a single bidirectional SCIO line, where clock and data are embedded in one signal stream; internal re-synchronization circuitry tolerates ±0.50% frequency drift per byte and ±0.06 UI edge jitter to maintain reliable communication under voltage/temperature variation.
It integrates a status register with WIP and WEL flags, 16-byte page latches, high-voltage generation for EEPROM programming, and slope-controlled output drivers to suppress ground bounce - all managed by on-chip memory control logic without external components.
Key Specifications

Pinout & Package
11LC160T-E/MNY is housed in an 8-lead MSOP (MN) package - ultra-thin, surface-mount, thermally enhanced for automotive PCBs with tight spacing constraints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SCIO | Serial Clock/Data I/O | Bidirectional Manchester-encoded bus line - carries clock + data; requires no separate clock pin or pull-up resistor in master-driven topology. |
| VSS | Ground | Reference return path for SCIO signaling and internal charge pump - must be low-impedance for stable write operations. |
| VCC | Supply Voltage | Power input for logic and EEPROM programming - internally regulates HV for cell writes; decoupling capacitor required per datasheet. |
| NC | No Connect | Unbonded pad - must remain floating; no routing or thermal relief connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| UNI/O® Serial Interface | Single I/O reduces MCU pin count and PCB routing complexity - eliminates need for dedicated SPI/I²C peripherals in cost-sensitive ECUs. |
| Schmitt Trigger Inputs | 0.05×VCC hysteresis on SCIO - rejects noise spikes up to 50 ns duration, improving robustness in electrically noisy engine bays. |
| Output Slope Control | Controlled edge rate on SCIO - prevents ground bounce-induced glitches during fast transitions in high-speed digital subsystems. |
| Status Register Access | Real-time WIP/WEL monitoring via RDSR command - enables non-blocking polling during firmware update sequences without blocking main thread. |
| Block Write Protection | Configurable 0%, 25%, 50%, or 100% array protection via BP0/BP1 bits - isolates critical bootloader sectors from accidental overwrites. |
| Auto-Erase & Page Buffer | Self-timed erase-before-write + 16-byte buffer - reduces host MCU intervention and total write time vs. byte-by-byte programming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C128C-MAHM-T | I²C interface (2-wire), 128 Kbit density, 1.7–5.5V supply, no built-in Schmitt triggers or slope control. | Requires two dedicated MCU pins (SCL/SDA); higher pin count and less noise immunity in high-EMI steering columns. | Select when existing I²C infrastructure exists and higher density is needed; not drop-in due to protocol and pinout mismatch. |
| BR24G128FJ-WE2 | UNI/O® compatible but rated only for Industrial (-40°C to +85°C); same 16 Kbit density and SCIO pinout. | Lacks AEC-Q100 qualification and 125°C operation - unsuitable for under-hood placement or EPS motor control units. | Consider only for cabin-mounted modules where ambient temperature stays below 85°C; verify automotive qualification status before design-in. |
Compared with AT24C128C-MAHM-T and BR24G128FJ-WE2, the 11LC160T-E/MNY uniquely combines Automotive E-grade temperature range, UNI/O® single-pin simplicity, and integrated noise suppression - making it the only option qualified for direct integration into ASIL-B–relevant powertrain and chassis subsystems without additional signal conditioning.

FAQ
What is the UNI/O® interface used by the 11LC160T-E/MNY, and how does it differ from I²C or SPI?
The 11LC160T-E/MNY uses Microchip's patented UNI/O® bus - a single-wire, Manchester-encoded serial interface where clock and data are embedded in one SCIO signal. Unlike I²C (2-wire, open-drain) or SPI (4-wire, separate clock/data), UNI/O® eliminates dedicated clock lines and reduces MCU pin count. It requires no external pull-ups and supports deterministic timing with built-in re-synchronization, making it ideal for electrically noisy automotive environments where I²C may suffer from clock stretching or arbitration issues.
Does the 11LC160T-E/MNY support write protection, and how is it configured?
Yes, the 11LC160T-E/MNY supports configurable block write protection via two nonvolatile BP0/BP1 bits in its STATUS register. These bits can protect 0%, 25%, 50%, or 100% of the memory array - set using the WRSR (Write Status Register) command. Protection is enforced at the hardware level during WRITE commands, preventing accidental overwrites of critical calibration or bootloader data. The 11LC160T-E/MNY also includes automatic power-on/off write protection and a write-enable latch (WEL) that must be set via WREN before any write operation.
What is the maximum operating temperature and qualification status of the 11LC160T-E/MNY?
The 11LC160T-E/MNY is rated for -40°C to +125°C (Automotive E-grade) and is AEC-Q100 qualified for use in automotive powertrain and chassis applications. Its electrical specifications - including 1 µA max standby current at 125°C, 100 kbps bus speed, and 1M endurance - are fully characterized across this full temperature range. This makes the 11LC160T-E/MNY suitable for under-hood modules such as engine control units, transmission control units, and electric power steering systems where sustained high-temperature reliability is mandatory.
How does the 11LC160T-E/MNY handle power loss during a write cycle?
The 11LC160T-E/MNY incorporates built-in power-loss protection circuitry that monitors VCC and aborts write operations if supply voltage drops below safe thresholds. If power fails mid-write, the internal state machine rolls back to a known-good state, and no partial or corrupted data is committed to the EEPROM array. Additionally, the device features automatic erase-before-write and page buffering - ensuring that only complete, validated 16-byte pages are programmed. This guarantees data integrity even in vehicles experiencing cranking transients or battery disconnect events.
Can the 11LC160T-E/MNY be used with microcontrollers lacking native UNI/O® support?
Yes - the 11LC160T-E/MNY requires only a single general-purpose I/O pin configured for bidirectional, open-drain–like operation. Any MCU (including ARM Cortex-M, PIC, or legacy 8051) can implement the UNI/O® protocol in firmware using precise timing loops or timer peripherals. Microchip provides reference code examples and timing diagrams in DS22067J. No special hardware peripheral is needed, and the 11LC160T-E/MNY's Manchester encoding eliminates clock skew concerns - unlike bit-banged I²C or SPI implementations.
