Frequently Asked Questions
How many bytes can 24LCS52-I/MS store and how is the memory organized for I2C access?
The 24LCS52-I/MS provides 2 kbit (256 bytes) of EEPROM organized as 256 x 8-bit words. Each byte is individually addressable over the I2C bus using the standard 1010DDDR control byte format, allowing random read and sequential read operations. Page write operations can program up to 16 bytes per write cycle, reducing total programming time for bulk configuration data.
What write endurance and data retention specifications does 24LCS52-I/MS guarantee for industrial applications?
The 24LCS52-I/MS is rated for 1,000,000 write/erase cycles per byte and a minimum 200-year data retention at 25°C. These specifications exceed typical industrial requirements, making it suitable for applications such as smart meters, industrial sensors, and medical implants where EEPROM cells must reliably store calibration and trim data over the product lifetime.
Which supply voltage range does 24LCS52-I/MS support and how does this benefit mixed-voltage embedded designs?
Operating from 2.2 V to 5.5 V, the 24LCS52-I/MS interfaces directly with 3.3 V microcontrollers and legacy 5 V systems without level shifters. The 400 kHz maximum clock frequency (fast-mode I2C) allows rapid burst reads in real-time systems, while the low standby current of typically 1 µA minimizes power draw in battery-operated nodes.
How does the 8-pin MSOP package of 24LCS52-I/MS compare to DIP alternatives for space-constrained PCB layouts?
The MSOP-8 package measures only 3 mm x 3 mm with 0.65 mm pitch, roughly 60% smaller than an equivalent 8-pin DIP. This compact footprint enables placement near the host MCU on densely populated boards in hearing aids, wearables, and IoT edge devices, while the 8-address-pin flexibility allows up to 8 devices sharing a single 2-wire I2C bus.
