Atlantik Elektronik, provider of innovative embedded solutions, presents the new HyperRAM® from Winbond.

With the rapid rise of automotive electronics, industrial 4.0, and smart home applications, new IoT edge devices and human-machine interface devices will require new functionality in terms of size, power consumption, and performance.  In view of this, many MCU suppliers are developing new-generation MCUs with higher performance and lower power consumption to meet the market demand.  In addition, from the overall system design perspective, the RAM that works with the MCU also requires new options to provide better advantages than those of the existing SDRAM and pSRAM.

HyperRAM® supports the HyperBus® interface and Winbond Electronics offers 32, 64 and 128Mbit devices. The computing power, data processing and image display functions of traditional MCUs are limited and that the new IoT devices often have touch panel as image control interface, or require stronger edge computing functions for image processing and speech recognition, requiring higher performance, lower power microcontrollers.

Winbond’s 64Mbit HyperRAM® consumes 90 microW at 1.8V, which is about half of a DRAM of the same capacity, claims the company. The power consumption of HyperRAM® is only 45 microW at 1.8V in hybrid sleep mode – as opposed to the standby mode of an SDRAM. A low power SDRAM has a larger form factor than HyperRAM®.

In addition, HyperRAM® has only 13 signal pins, which can greatly simplify the PCB layout design.  It also means that when designing end products, developers can use microcontrollers with more pin-out for other purposes or use microcontrollers with fewer pins for cost-effectiveness. Simplifying control interface is another feature of HyperRAM®.  Based on pSRAM architecture, HyperRAM® is a self-refresh RAM.  It can automatically return to standby mode. This means system memory is easier to use, and the development of firmware and drivers is also simplified.

Winbond’s HyperRAM® 32Mbit device has entered mass production; the 64 and 128Mbit are expected to enter mass production in 1Q2020 respectively and can be ordered also at Atlantik Elektronik.
