CAT25320HU4I-GT3

Product Overview

The onsemi CAT25320HU4I-GT3 is a 32Kbit non-volatile EEPROM memory IC with an SPI interface. It is organized as 4K x 8 and supports a 10 MHz clock. The device operates from 1.8V to 5.5V and is specified for an ambient temperature range of -40°C to 85°C. It is housed in an 8-UFDFN Exposed Pad package with surface-mount construction, and the 8-UDFN-EP (2x3) package form is used for compact embedded memory functions.

Key Features

• 5ms word/page write cycle time
• Non-volatile EEPROM technology
• 8-UFDFN Exposed Pad surface-mount package
• Operating temperature -40°C to 85°C (TA)

Applications

• Storing configuration parameters in microcontroller-based equipment
• Retaining calibration data for sensor modules
• Holding device identification or setup records in compact assemblies
• Preserving settings in low-voltage embedded systems

Design & Procurement Notes

Designers should verify that the host SPI controller supports the 10 MHz clock and matches the device timing requirements. The 5ms word/page write cycle time should be considered in firmware write routines and power-up sequencing. The 1.8V to 5.5V supply range and -40°C to 85°C operating temperature range should be checked against the board environment. The 8-UFDFN Exposed Pad surface-mount package and 8-UDFN-EP (2x3) package form may require appropriate PCB pad layout and reflow profile. Confirm package compatibility, thermal conditions, and host interface timing before integration.
