Frequently Asked Questions
What clock frequency does the 11LC040-I/SN support, and how does it affect data throughput?
The 11LC040-I/SN supports a maximum clock frequency of 1 MHz, enabling serial data transfer rates suitable for most microcontroller applications. At 1 MHz, byte-level reads and writes complete in microseconds, making it efficient for low-power embedded designs with 4Kbit of storage organized as 512x8 bits.
How many write cycles can the 11LC040-I/SN endure before data retention degrades?
The 11LC040-I/SN is rated for up to 1,000,000 write/erase cycles per byte location, with a minimum data retention of 200 years. This endurance rating makes it reliable for applications that require frequent configuration updates or event logging in industrial and consumer devices operating at 2.5V to 5.5V.
Which embedded systems benefit most from using the 11LC040-I/SN over larger EEPROMs?
Applications requiring only 4Kbit (512 bytes) of non-volatile storage benefit from the 11LC040-I/SN due to its small 8-pin SOIC footprint, low operating voltage down to 2.5V, and 1 MHz serial interface. IoT sensors, wearable devices, and calibration-data storage in battery-powered systems are ideal use cases where minimal memory suffices.
Is the 11LC040-I/SN compatible with 3.3V microcontroller systems?
Yes, the 11LC040-I/SN operates across a wide voltage range of 2.5V to 5.5V, making it fully compatible with 3.3V microcontroller systems. Its SPI-compatible serial interface allows straightforward connection to modern 32-bit and 8-bit microcontrollers without level-shifting circuitry in most designs.
