Frequently Asked Questions
What write endurance and data retention does 93LC46C-I/P provide for non-volatile storage applications?
The 93LC46C-I/P is rated for 1,000,000 write/erase cycles and a minimum 200-year data retention period, ensuring reliable long-term storage of configuration settings, calibration values, and serial numbers in embedded systems.
Which interface does 93LC46C-I/P use and at what maximum clock speed does it operate?
The 93LC46C-I/P uses a 3-wire Microwire-compatible serial interface with a maximum clock frequency of 3 MHz, allowing straightforward integration with most 8-bit and 16-bit microcontrollers using standard SPI or bit-bang GPIO.
Is 93LC46C-I/P suitable for mixed 3.3 V and 5 V board designs without level-shifting circuitry?
Yes, the 93LC46C-I/P operates across a 2.5 V to 5.5 V supply range, covering both 3.3 V and 5 V logic systems. This eliminates external level shifters in many mixed-voltage designs, reducing component count and board space in 8-pin PDIP layouts.
