Frequently Asked Questions
How many write/erase cycles can the 93LC86C-I/P endure before data reliability degrades?
The 93LC86C-I/P is rated for a minimum of 1,000,000 write/erase cycles per memory location. At a typical firmware update rate of once per day, this equates to over 2,700 years of reliable operation, making the device suitable for parameters that change frequently, such as calibration offsets or operational counters in industrial equipment.
Which supply voltage range does 93LC86C-I/P support, and can it operate at 3.3 V in modern microcontroller systems?
The 93LC86C-I/P operates from 2.5 V to 5.5 V, encompassing both 3.3 V and 5 V microcontroller supply rails. At 3.3 V, the 2 MHz maximum clock frequency is maintained, allowing seamless integration with modern low-voltage MCUs without level translation, while the 8-pin PDIP package simplifies prototyping.
How long will data stored in the 93LC86C-I/P persist without power, and what does this mean for factory-programmed settings?
Data retention in the 93LC86C-I/P is guaranteed for a minimum of 200 years under standard operating conditions, ensuring factory-programmed calibration constants, serial numbers, and configuration bytes remain intact throughout the entire product lifetime — even after decades on the shelf or in storage at temperatures up to 85°C.
Can 93LC86C-I/P be configured for 8-bit or 16-bit word organization, and how is that selected?
Yes. The 93LC86C-I/P supports both 8-bit (2K words) and 16-bit (1K words) organization modes. The ORG pin selects the word width: tie ORG to VSS for 8-bit mode, or to VCC for 16-bit mode. This flexibility allows the same device to match different firmware data structures without requiring two separate part numbers in the design.
