CAT25C16LGI

Product Overview

The onsemi CAT25C16LGI is a non-volatile EEPROM memory IC with a 16Kbit capacity organized as 2K x 8. It communicates through an SPI interface and supports a clock frequency of 10 MHz. The device provides a 40 ns access time and a 5ms write cycle time for word or page operations. It operates from a 2.5V to 5.5V supply and is specified for an ambient temperature range of -40°C to 85°C. The part is mounted through hole and is offered in an 8-DIP package with a 0.300 in body width and 7.62 mm pitch, identified as 8-PDIP.

Design & Procurement Notes

Designers should match the SPI clock timing, supply voltage, and 5ms write cycle behavior to the host controller and power sequencing in the target system. The 2K x 8 organization means the memory is addressed as 2,048 eight-bit locations, which should be reflected in firmware data structures and page write routines. The through-hole 8-DIP package is suitable for prototyping, breadboard layouts, and board designs that require pin insertion rather than surface-mount assembly. The specified -40°C to 85°C ambient range and 2.5V to 5.5V supply range should be compared with the final system environment and available voltage rails before integration.
