CY15V104QN50BFXITXUMA1

Memory IC Overview

The Infineon CY15V104QN50BFXITXUMA1 is a 4-Mb EXCELON™ LP Ferroelectric RAM (F-RAM) logically organized as 512K × 8 bits. It features an SPI interface supporting up to 50 MHz and operates at VDD = 1.71 V to 1.89 V. The device offers 10^15 read/write endurance, 151-year data retention, and includes a dedicated 256-byte special sector. Power consumption is 2.4 mA active, 2.3 µA standby, 0.70 µA deep power-down, and 0.1 µA hibernate.

Memory IC Feature Summary

• Provides virtually unlimited endurance of 1000 trillion read/write cycles with 151-year data retention.
• Features instant non-volatile write technology allowing writes at bus speed without polling delays.
• Includes sophisticated hardware and software write protection schemes for data integrity.
• Integrates Device ID, Unique ID, and writable serial number registers for system identification.

Memory IC Applications

• Data collection systems requiring frequent or rapid writes
• Industrial controls demanding high-speed nonvolatile memory
• Hardware drop-in replacements for serial EEPROM or flash

Memory IC Procurement Notes

Verify the specific ordering suffix 'XUMA1' against official Infineon documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the low-voltage variant (CY15V104QN) matches the target supply voltage range of 1.71 V to 1.89 V. Confirm industrial temperature grade availability for the specific batch.

Memory IC Selection Notes

Select this component when applications require high-speed serial writes without the latency associated with flash or EEPROM. The low-voltage operation makes it suitable for battery-powered or energy-constrained systems. Verify that the host microcontroller supports SPI modes 0 or 3 and can handle the 50 MHz clock frequency for optimal performance.

Memory IC Part Context

This part belongs to the EXCELON™ LP F-RAM family, designed to replace traditional nonvolatile memories in serial interfaces. It utilizes advanced ferroelectric process technology to eliminate write delays and provide superior endurance compared to standard serial flash devices.

Memory IC Replacement Considerations

Direct pin-compatible replacements within the same package may include other CY15V104QN variants with different speed grades or packaging options, provided the voltage and temperature specifications align with the design requirements.
