The HYPERRAM product range offers compact alternatives to traditional pseudo-SRAM and is intended for low power, space-constrained IoT applications that require an off-chip external RAM. HYPERRAM 3.0 operates at a maximum frequency of 200MHz with a 1.8V operation voltage, which is the same as both HYPERRAM 2.0 and OCTAL xSPI RAM, but with an increased data-transfer rate of 800MBps – double the rate that was previously available.
The new generation HYPERRAM operates via an expanded IO HyperBus interface with 22 pins.
"As a provider of memory solutions, Infineon provides a family of solutions that deliver high performance in smaller form factors for next-generation IoT applications," said Ramesh Chettuvetty, Sr. Director of Marketing and Applications at Infineon Technologies. "HYPERRAM 3.0 is the third generation of the HYPERRAM family that supports throughput of up to 800MBps using a new 16-bit extended version of the HyperBus interface. The 256Mb HYPERRAM 3.0 devices are now sampling.”
"Low pin count, low power consumption and easy control are three key features of HYPERRAM that help it significantly improve the performance of IoT end devices," according to a spokesperson for Winbond. "HYPERRAM significantly simplifies the PCB layout design, extends mobile devices' battery life, and works with a smaller processer via a lower pin count while increasing throughput compared to low-power DRAM, SDRAM, and CRAM/PSRAM.”
Today’s IoT devices execute more than simple machine to machine communication, performing voice control or tinyML inferences and therefore need a higher memory performance.
The HYPERRAM family has been developed for low-power IoT applications, such as wearables, instrument clusters in automotive applications, infotainment and telematics systems, industrial machine vision, HMI displays and communication modules.
HYPERRAM 3.0 is the latest generation and is able to operate under the same command/address signal and similar data bus format with enhanced bandwidth and the same standby power with little pin change. The first member of the HYPERRAM 3.0 family will be a 256Mb device in a KGD, WLCSP Package, which can be implemented at the component level, module level or PCB level based on the end product type.
- HYPERRAM is a high-speed, low-pin-count, low-power pseudo-SRAM for high-performance embedded systems requiring expansion memory for scratchpad or buffering purposes. Introduced by Infineon (then Cypress) in 2015, HYPERRAM now enjoys mature and broad ecosystem support from leading MCU, MPU and FPGA chipset partners and customers. Its low-pin count architecture makes HYPERRAM especially suitable for power and board space-constrained applications requiring off-chip external RAM. Optimised HyperBus memory controllers are available from multiple third-party IP vendors.
