Infineon Technologies has launched the industry’s first automotive qualified 1Mbit serial ferroelectric RAM (FRAM) for data logging as well as 1 4Mbit device.
Demand for automotive event data recorders (EDR) is driving more specialist designs with memory devices that instantly capture and reliably store critical data for decades.
The 1Mbit CY15B201QN-50SXE Excelon FRAM memories are AEC-Q100 Grade 1 qualified and support an extended temperature range (-40°C to +125°C). The highly reliable read/write performance at speeds up to 50 MHz in SPI mode is supported by an endurance of trillion read/write cycles to support data logging at 10 microsecond intervals for over 20 years.
Infineon also expects to release the Quad SPI interface version of this and the 4Mbit devices by the end of this year.
- First space-qualified serial interface FRAM
- Infineon ships 8 and 16Mbit industrial FRAM memories
- 4Mbit FRAM has automotive operating temperature range
The zero delay write allows system data to be captured and recorded up to the last instant before an accident or other user-defined trigger event and the device is designed to retain data for more than 100 years after loss of power.
“Data logging requirements are growing rapidly in automotive systems, as trends toward broader use of electronic systems and industry regulations have encouraged the use of high-reliability non-volatile memories in airbag safety systems, along with engine control and battery management systems,” said Ramesh Chettuvetty, Vice President RAM Solutions at Infineon.
“The demand for memory densities tailored to specific use cases has grown as the number of applications requiring data logging have increased. Infineon is committed to providing our customers with the flexibility to meet the memory architecture requirements of any system design.”
Both of the devices use the serial SPI interface, operate from 1.8 V to 3.6 V and come in a standard 8-pin SOIC package and are part of a range of FRAMs ranging from 4Kbit up to 16Mbit.
Both the 1Mbit CY15B201QN-50SXE and 4Mbit CY15B204QN-40SXE Auto FRAM devices are in volume production.
