Frequently Asked Questions

What memory organization options does the 93LC56C-I/MS support?

The 93LC56C-I/MS supports two memory organization modes: 256x8-bit (byte-wide) or 128x16-bit (word-wide), selectable via the ORG pin. This dual organization makes it compatible with a wide range of 8-bit and 16-bit microcontroller architectures without requiring a different part number.

What is the maximum clock frequency and interface type for the 93LC56C-I/MS?

The 93LC56C-I/MS communicates over a 3-wire SPI-compatible serial interface with a maximum clock frequency of 2 MHz. This low-speed interface is compatible with virtually all microcontrollers and FPGAs, making integration straightforward in most embedded system designs.

How long can the 93LC56C-I/MS retain data and what is its endurance rating?

The 93LC56C-I/MS offers a minimum data retention time of 200 years and supports up to 1,000,000 write/erase cycles per cell. These specifications make it well suited for applications requiring both high endurance and long-term reliable non-volatile data storage.

What package does the 93LC56C-I/MS use and is it lead-free?

The 93LC56C-I/MS comes in an 8-pin MSOP (Mini Small Outline Package) with a compact footprint ideal for space-constrained designs. It is Pb-free (RoHS compliant, JESD-609 code e3), meeting environmental compliance requirements for commercial and industrial applications.
