Product details
Overview
11LC160T-E/SN 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, 1 µA max standby current, and built-in block write protection for automotive body control modules, sensor calibration storage, and infotainment configuration memory.
For engineers reviewing the 11LC160T-E/SN datasheet, 11LC160T-E/SN pinout, 11LC160T-E/SN application, or 11LC160T-E/SN equivalent, this page delivers verified electrical specs, UNI/O® timing constraints, package-specific terminal mapping, automotive-grade reliability data, and real-world substitution guidance for legacy EEPROM migration.
Technical Context
The 11LC160T-E/SN implements Manchester-encoded UNI/O® protocol over a single SCIO bidirectional pin, eliminating need for separate clock and data lines. It uses internal re-synchronization circuitry tolerant to ±0.5% frequency drift per byte and ±0.06 UI input edge jitter, enabling robust communication in electrically noisy automotive environments.
Its architecture includes a nonvolatile STATUS register with WIP and WEL bits, 16-byte page latches, Schmitt-triggered SCIO input with 0.05×VCC hysteresis, and slope-controlled output to suppress ground bounce - all supporting self-timed 5–10 ms write cycles with auto-erase and >1 million endurance cycles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT24C128C-SSHL-T | I²C interface (2-wire), 128 Kbit density, 1.7–5.5V supply, 1 MHz max clock, no UNI/O® or slope control | Requires two MCU pins and external pull-ups; higher speed but less noise-immune in high-EMI zones | Choose for systems already using I²C infrastructure and needing larger capacity; avoid where pin count or EMC margin is constrained. |

FAQ
What is the UNI/O® bus interface used by the 11LC160T-E/SN?
The 11LC160T-E/SN uses Microchip's patented UNI/O® serial bus, which combines clock and data onto a single bidirectional SCIO line using Manchester encoding. This eliminates separate clock lines and reduces MCU pin requirements versus I²C or SPI. The 11LC160T-E/SN supports up to 100 kbps bit rate with built-in re-synchronization to tolerate frequency drift and edge jitter - essential for automotive ECU integration.
Does the 11LC160T-E/SN support hardware write protection?
Yes, the 11LC160T-E/SN includes configurable block write protection controlled by BP0 and BP1 bits in its STATUS register. These nonvolatile bits allow locking 0%, 25%, 50%, or 100% of the 16 Kbit array against accidental writes. Protection is enforced at the silicon level and remains active even after power cycling - a key requirement for ASIL-B firmware parameter storage in the 11LC160T-E/SN.
What is the maximum operating temperature for the 11LC160T-E/SN?
The 11LC160T-E/SN is rated for -40°C to +125°C (Automotive E-temp grade), fully qualified per AEC-Q100. This specification is confirmed in DS22067J-page 1 device selection table and electrical characteristics section. Its 125°C capability enables direct placement in high-heat zones such as engine compartments, transmission control units, and front-radar housings - a critical differentiator from industrial-grade alternatives.
How many write/erase cycles does the 11LC160T-E/SN guarantee?
The 11LC160T-E/SN guarantees 1,000,000 erase/write cycles per memory location, as specified in DS22067J-page 1 Features and Table 1-2 AC Characteristics. This endurance is validated at 25°C and 5.5V, and supports >15 years of daily recalibration in automotive applications - exceeding typical OEM requirements for ECU configuration storage.
What package type does the 11LC160T-E/SN use?
The 11LC160T-E/SN uses an 8-lead SOIC package with suffix "SN", as explicitly listed in the Device Selection Table (DS22067J-page 2). This standard SOIC-8 footprint features NC pins at positions 1–3 and 5–7, VSS at pin 4, VCC at pin 8, and SCIO as the sole functional I/O. The package is Pb-free and RoHS compliant, with thermal performance validated for automotive reflow profiles.
