CAT25040P

Product Overview

The CAT25040P from onsemi is a non-volatile EEPROM memory IC offering 4Kbit of storage organized as 512 x 8 bits. It uses an SPI serial interface and operates from a 2.5V to 5.5V supply. The device is supplied in an 8-PDIP through-hole package, with a package body of 8-DIP (0.300\", 7.62mm). Its specified operating temperature range is 0°C to 70°C (TA).

Key Features

• 4Kbit EEPROM memory with 512 x 8 organization
• SPI serial memory interface
• Non-volatile memory type
• 2.5V to 5.5V supply voltage range
• 5 ms write cycle time for word/page operations
• 0°C to 70°C (TA) operating temperature range
• Through-hole 8-PDIP package, 8-DIP (0.300\", 7.62mm)

Applications

• Storing device configuration parameters in embedded systems
• Retaining calibration or identification data in instrumentation
• Providing nonvolatile memory for small data sets in consumer electronic devices

Design & Procurement Notes

For system design, verify that the host controller supports SPI signaling and that the selected supply remains within 2.5V to 5.5V under all operating conditions. The 0°C to 70°C (TA) range should be checked against the target environment, and the through-hole 8-PDIP package requires corresponding socket or PCB hole layout. Because the word/page write cycle time is 5 ms, account for write latency in firmware and avoid assuming faster nonvolatile update timing. The 512 x 8 organization means addressing should be planned in bytes, and the 4Kbit capacity provides a fixed upper limit for stored data.
