Infineon HYPERRAM™ pSRAM Memory

More bandwidth for low pin-count and small footprint

Infineon offers a comprehensive portfolio of HYPERRAM™/Octal xSPI RAM memories with densities ranging from 64 Mb to 512 Mb. With its unique blend of high bandwidth and low pin-count, HYPERRAM™ is ideal for a wide range of industrial and automotive applications that require additional RAM for data-intensive operations. These energy efficient pSRAMs are also the ideal expansion memory choice for battery-operated consumer and wearable devices.

HYPERRAM™ - Pseudostatic RAM (pSRAM) Technology

HYPERRAM™ is a high-speed CMOS, self-refresh DRAM, with a HYPERBUS™ interface. Its memory array is internally structured like DRAM, but externally acts like SRAM.

The DRAM array requires a periodic refresh to maintain data integrity. HYPERRAM™ internally manages the refresh operations on the DRAM array when the memory is not being actively read or written by a host. Since the host is not required to manage any refresh operations, the DRAM array appears to the host as static cells that retain data without refresh. Hence, HYPERRAM™ is described as pseudostatic RAM (pSRAM).

These low-power, high-performance, and low pin-count pSRAMs are suitable for applications requiring additional RAM for buffering data, audio, images, video, or as a scratchpad for math and data-intensive operations.

  • Density: 64 Mb, 128 Mb, 256 Mb, 512 Mb
  • Interface: HYPERBUS™ (x8), Octal xSPI (x8), and HYPERBUS™ Extended I/O (x16)

Key Features

  • Small-form-factor - FBGA package ensures a small PCB footprint
  • Low pin-count - simplifies design and reduces system cost

 

  • Low power - hybrid sleep mode and partial-array-refresh for energy efficiency
  • High throughput - high read/write bandwidth to maximize system performance

 

More Info

Infineon introduced the first generation of HYPERRAM devices supporting the HyperBus interface in 2017. The second generation of HYPERRAM devices were introduced in 2021 and support both the Octal xSPI and HyperBus JEDEC-compliant interfaces with data rates of up to 400 MBps. The third generation of HYPERRAM devices support the new extended HyperBus interface enabling 800 MBps data rates. HYPERRAM devices are available in density range of 64 Mb to 512 Mb. They are AEC-Q100 qualified and support industrial and automotive temperature grades up to 125°C.
