Microchip Technology 11LC010-I/P

Overview

11LC010-I/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 supply, featuring 16-byte page write buffer, 1 µA max standby current (I-temp), and Schmitt-trigger SCIO input for noise immunity in space-constrained industrial control and sensor calibration applications.

For engineers reviewing the 11LC010-I/P datasheet, 11LC010-I/P pinout, 11LC010-I/P application, or 11LC010-I/P equivalent, this device supports Manchester-encoded serial communication at up to 100 kbps, includes STATUS register access for WIP/WEL monitoring, and offers block write protection (none/1/4/1/2/all) - critical for firmware parameter storage in embedded systems with minimal GPIO resources.

Technical Context

The 11LC010-I/P implements a Manchester-encoded UNI/O® protocol over a single bidirectional SCIO line, eliminating need for separate clock and data lines. It uses internal re-synchronization circuitry tolerant of ±0.50% frequency drift per byte and ±0.06 UI edge jitter, enabling robust operation across voltage and temperature variations.

Internally, it integrates an 8-bit instruction register, page latches for 16-byte buffered writes, HV generator for EEPROM programming, and a current-limited slope-controlled SCIO driver to suppress ground bounce. The STATUS register provides real-time WIP and WEL status, while BP0/BP1 bits enable nonvolatile block protection configuration via WRSR command.

FAQ

What is the UNI/O® interface used by the 11LC010-I/P?

The 11LC010-I/P uses Microchip's patented UNI/O® bus - a single-wire, Manchester-encoded serial interface that combines clock and data into one bidirectional SCIO signal. This eliminates separate clock lines and reduces GPIO usage, making the 11LC010-I/P ideal for microcontroller designs with limited I/O resources. The 11LC010-I/P supports bit rates up to 100 kbps and includes built-in re-synchronization to tolerate frequency drift and edge jitter.

Does the 11LC010-I/P support write protection?

Yes, the 11LC010-I/P includes configurable block write protection controlled via BP0/BP1 bits in its STATUS register. Protection can be set to lock none, 1/4, 1/2, or all of the 128-byte memory array using the WRSR command. Additionally, hardware-level write protection is implemented through power-on/off circuitry and a write-enable latch (WEL), ensuring data integrity during supply transients - a key feature of the 11LC010-I/P for mission-critical storage.

What packages are available for the 11LC010-I/P?

The 11LC010-I/P is offered in 8-lead PDIP (P), SOIC (SN), MSOP (MS), TDFN (MN), SOT-23 (TT), and TO-92 (TO) packages. The "-I/P" suffix explicitly denotes the Industrial-grade 8-lead PDIP variant. All packages share identical electrical specifications and UNI/O® functionality, allowing direct migration between form factors based on board space and thermal requirements - the 11LC010-I/P PDIP version is commonly selected for prototyping and through-hole manufacturing.

How does the 11LC010-I/P handle power supply variations during write operations?

The 11LC010-I/P incorporates built-in power-on/off write protection circuitry that disables writes during VCC ramp-up or brownout conditions. If VCC falls below the functional threshold during a write cycle, the 11LC010-I/P aborts the operation and retains prior valid data. Its specified VCC range of 2.5V to 5.5V ensures stable operation across common industrial rails, and the STATUS register's WIP bit allows software to verify completion before proceeding - critical for robust firmware integration with the 11LC010-I/P.

What is the endurance and data retention specification for the 11LC010-I/P?

The 11LC010-I/P guarantees 1,000,000 erase/write cycles per memory location and greater than 200 years of data retention at +85°C ambient temperature. These figures are characterized and specified in Microchip's DS22067J datasheet under standard test conditions (25°C, VCC = 5.5V). The high endurance enables frequent field updates in applications like sensor recalibration, while the exceptional retention ensures long-term reliability in sealed or maintenance-free deployments - core reliability attributes of the 11LC010-I/P.
