CHANDLER, Ariz., March 28, 2024 (GLOBE NEWSWIRE) — To meet the overall customer need for larger and faster SRAM, Microchip’s technology (Nasdaq: MCHP) expand yours Serial SRAM product line to include higher densities up to 4 Mb and increased Serial Peripheral Interface/Serial Quad I/O™ Interface (SPI/SQI™) speeds up to 143 MHz. The 2 Mb and 4 Mb devices are designed to provide a lower cost alternative to traditional parallel SRAM products and include an optional battery backup switching circuit in the SRAM memory to preserve data in the event of power loss.
Unlike parallel RAM, which requires large packages and at least 26–35 microcontroller (MCU) I/O devices to interface, Microchip’s serial SRAM devices come in a cheaper 8-pin package and use a high-speed SPI/SQI communication bus. which requires only 4−6 MCU I/O pins for easy integration. This reduces the need for a more expensive MCU with a large pin count and can help minimize the overall board footprint.
Addressing the most common drawback of serial SRAM – that parallel is faster than serial – the 2 Mb and 4 Mb serial SRAM devices have increased the bus speed to 143 MHz with optional quad SPI (4 bits per clock cycle) , which significantly minimizes the speed difference between the solutions.
“Serial SRAM is a popular solution for engineers who need more RAM than is available on board their MCUs, but want to reduce cost and overall board size,” said Jeff Leeser, director of product business with Microchip memory. “Microchip’s 2 Mb and 4 Mb serial SRAM devices are designed to replace expensive parallel SRAM with an easy and cost-effective alternative.”
Small form factor, low power, high performance serial SRAM devices have unlimited endurance and zero write time, making them excellent options for applications involving continuous data transfer, buffering, data logging, measurement, and other math and data intensive applications functions. These devices are available from 64 Kbit to 4 Mb in density and support SPI, SDI and SQI bus modes.
