FM1110-QG

Specialized Overview

The Ramtron FM1110-QG is a non-volatile memory component utilizing Ferroelectric Random Access Memory (FeRAM) technology. It provides 1 Megabit of storage capacity, organized as 128K words by 8 bits. The device features a Serial Peripheral Interface (SPI) for data communication and operates within a supply voltage range of 2.7V to 3.6V. It supports standard SPI modes including Mode 0 and Mode 3. The unit is designed for industrial temperature ranges and is housed in an 8-pin SOIC package.

Specialized Feature Summary

• Utilizes ferroelectric material for non-volatile data retention without requiring charge pumping circuits.

Specialized Applications

• Industrial control systems requiring frequent data logging

Specialized Procurement Notes

Verify the specific suffix against official documentation to confirm exact package type and temperature grade. Confirm current availability status as product lines may undergo discontinuation or lifecycle changes. Ensure compatibility with existing system voltage levels before integration.

Specialized Selection Notes

Select this component when high endurance write cycles are required compared to Flash memory. Consider the 128Kx8 organization for applications needing byte-level access. Verify that the SPI interface timing meets the system clock requirements.

Specialized Part Context

This part belongs to the Ramtron FM11xx series of FeRAM devices. Ramtron was acquired by Cypress Semiconductor, which was subsequently acquired by Infineon Technologies. This lineage affects datasheet availability and support channels.

Specialized Replacement Considerations

Direct pin-to-pin replacements include the Cypress CY15B104QSN and the Infineon S25FL116K if Flash is acceptable. Verify electrical characteristics carefully when substituting with different memory technologies.
