Infineon FRAM, 4MB Memory Size, 1.8V to 3.6V Supply Voltage - CY15B104QSN-108SXI

This FRAM provides non-volatile, high-speed memory storage in an 8-pin SOIC package for embedded applications. It operates across a broad supply range suitable for varied system voltages and is accessed via a quad-SPI Interface to support accelerated serial memory transfers. The device is specified for extended temperature operation, allowing use in harsher ambient conditions where standard consumer components might not suffice.

Features and Benefits:

• 108MHz maximum clock frequency enables Faster serial transfers
• 4 MB density delivers substantial non-volatile storage capacity
• 8-bit data bus supports byte-oriented system architectures
• 1.8V to 3.6V operating range reduces power-domain complexity
• -40°C to 85°C rating permits operation across wide temperatures

Applications

• Suitable for data logging in industrial control systems
• Ideal for firmware storage in embedded controllers
• Used with battery-backed systems for frequent writes
• Can be used for parameter storage in instrumentation
• Suitable for low-power sensor node memory requirements

What Interface does it use for high-speed communication?

It uses a quad-SPI (QSPI) Interface to enable parallel serial data lanes and higher throughput.

How is the memory organised for software addressing?

Memory is arranged as 512K words of 8 bits, allowing linear byte addressing across the 4 MB array.

What packaging and pin count should designers plan for?

The component is supplied in an SOIC package with 8 pins for straightforward PCB layout.

What environmental limits govern safe operation?

The device is rated to operate between -40°C and 85°C for use in extended-temperature applications.

Are there any material or regulatory considerations for manufacturing?

The component conforms to RoHS requirements for restricted substances.
