CAT25040VE-G

Product Overview

The CAT25040VE-G is an onsemi serial EEPROM memory IC from the CAT25040 series. It provides a 4Kbit non-volatile memory array organized as 512 x 8 and communicates through an SPI interface. The device supports a 5 MHz clock frequency, a 40 ns access time, and a 5 ms write cycle time for word or page operations. It operates from a 2.5V to 6V supply and is specified for an operating temperature range of -40°C to 125°C (TA). The part is supplied in an 8-SOIC surface-mount package.

Key Features

• 4Kbit EEPROM memory with 512 x 8 organization
• SPI serial interface with 5 MHz clock frequency
• 40 ns access time and 5 ms word/page write cycle time
• 2.5V to 6V supply voltage range
• Operating temperature range of -40°C to 125°C (TA)
• 8-SOIC surface-mount package with 0.154 in, 3.90 mm width

Applications

• Embedded systems that require non-volatile storage of configuration settings
• Devices that retain calibration values after power cycling
• Equipment that stores small data records, such as device identifiers, using an SPI-connected memory component

Design & Procurement Notes

The 5 ms write cycle time should be accounted for in firmware timing and write sequencing. The 2.5V to 6V supply range and SPI clock frequency of 5 MHz affect host interface selection. The 8-SOIC surface-mount package and 3.90 mm width influence PCB layout. The product status is Obsolete, so review lifecycle requirements before selecting this part for new designs.
