Frequently Asked Questions

What is the memory size and organization of the 93LC46C-I/MS?

The 93LC46C-I/MS is a 1 Kbit serial EEPROM that can be user-configured as 128 x 8 bits or 64 x 16 bits via the ORG pin, providing a flexible Microwire-compatible non-volatile memory.

What clock frequency and operating voltage does the 93LC46C-I/MS support?

It supports a Microwire-compatible serial clock up to 3 MHz across the industrial -40 °C to +85 °C range and operates from a 2.5 V to 5.5 V supply, suitable for low-power MCU designs.

What is the endurance and data retention of the 93LC46C-I/MS?

The 93LC46C-I/MS is rated for 1,000,000 erase/write cycles per byte and a minimum 200-year data retention, making it appropriate for repeatedly updated calibration, parameter, and config storage.

What package does the 93LC46C-I/MS ship in?

This -I/MS suffix part ships in an 8-pin MSOP package (JESD-30 S-PDSO-G8, JESD-609 e3 finish), a small-footprint surface-mount option that fits handheld and wearable PCBs.
