Memory chip doubles bandwidth with low pin-counts
Infineon Technologies AG has added HYPERRAM™ 3.0 to its portfolio of high-bandwidth, low-pin count memory products. The device features a new,16-bit extended version of the HyperBus™ interface that doubles throughput to 800 MB/s. With HYPERRAM 3.0, Infineon offers a portfolio of high-bandwidth memories with low pin-count and low-power. It is a perfect fit for applications requiring expansion RAM, including video buffering, factory automation, Artificial Intelligence of Things (AIoT) and automotive vehicle-to-everything (V2X), as well as applications requiring scratch-pad memory for intense mathematical calculations.
“With nearly three decades of memory knowledge, we are bringing another industry-first to the market. The new HYPERRAM 3.0 memory achieves a far higher throughput-per-pin than existing technologies in the market such as PSRAMs and SDR DRAMs,” said Ramesh Chettuvetty, Senior Director of Applications and Marketing at Infineon’s Automotive Division. “Our low-power features enable better power consumption, without sacrificing throughput, which also makes this memory ideal for industrial and IoT applications.”
Infineon’s HYPERRAM is a stand-alone PSRAM-based volatile memory that offers a simple and cost-optimized way to add extension memory. The data rates are equivalent to SDR DRAM but with much lower pin-count and lower power requirements. The increased per-pin data throughput of the HyperBus interface makes it possible to use microcontrollers (MCUs) with fewer pins and PCBs with fewer layers. This provides opportunities for lower-complexity and thus cost-optimized designs to support target applications.
Infineon introduced the first generation of HYPERRAM memory 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.
HYPERRAM 3.0 memory products can be ordered now in a BGA-49 package.
