Serial NOR Flash

SpiFlash® Memories with SPI, Dual-SPI, Quad-SPI and QPI

Winbond's W25X and W25Q SpiFlash® Multi-I/O Memories feature the popular Serial Peripheral Interface (SPI), densities from 512K-bit to 512M-bit, small erasable sectors and the industry's highest performance.

The W25X family supports Dual-SPI, effectively doubling standard SPI clock rates. The W25Q family is a "superset" of the 25X family with Dual-I/O and Quad-I/O SPI for even higher performance. Clock rates up to 104MHz achieve an equivalent of 416MHz (50M-Byte/S transfer rate) when using Quad-SPI. This is more than four times the performance of ordinary Serial Flash (50MHz) and even surpasses asynchronous Parallel Flash memories while using fewer pins and less space.

Faster transfer rates mean controllers can execute code with Execute in Place methods (XIP) directly from the SPI interface or further improve boot time when shadowing code to RAM.

Some SpiFlash® devices offer the new Quad Peripheral Interface (QPI) supporting true Quad Commands for improved XIP performance and simpler controller circuitry. Additionally, new ultra-small form factor packages are ideal for space constrained mobile and handheld applications.

Modern IoT devices rely on dedicated computer memory units to function. Random-access memory (RAM) units enable critical functions in these IoT devices and have evolved with an increasing need for compactness and functionality.

What Constitutes RAM?

Computer RAM can either be static random-access memory (SRAM) or dynamic random-access memory (DRAM). Each of these computer memory configurations plays a unique role in modern IoT devices and wearable tech.

SRAM vs. DRAM

Both SRAM and DRAM represent volatile forms of computing that are prone to loss of memory when the power source is interrupted. SRAM units temporarily store data by utilizing six-transistor memory cells, are faster, more efficient (require less power to operate than DRAMs), permit data remanence, and are generally costlier.

By contrast, DRAM works by combining a metal-oxide-semiconductor field-effect transistor (MOSFET) and a metal-oxide-semiconductor (MOS) capacitor to achieve temporary data storage. DRAM chips are cheaper but require a constant refresh from an external source to retain the data on their capacitors.

What Is Pseudo-Static RAM and What Makes It Unique?

Pseudo-static random-access memory (PSRAM or PSDRAM) chips combine the best features of both SRAM and DRAM computing units. PSRAM is a DRAM device that integrates a refresh feature, negating the need for an externally enabled data rewrite onto its MOS capacitor. These features make PSRAMs excellent for main memory applications in numerous wearable IoT devices and portable smart devices.

Winbond Offers Sophisticated PSRAM Solutions for Wearable Tech

Winbond's PSRAM solution offers low-profile, low-power performance ideal for IoT wearable devices. Pseudo SRAM (PSRAM) is experiencing a design revival with wearable devices. Also known as CellularRAM, PSRAM were widely used in feature mobile phones. A typical IoT wearable design requires low power for extended battery life and uses lower RAM density in the smallest possible packages. Most wearable is tasked to monitor a finite set of parameters which means not a lot of computing power or the need for large memory size. These design requirements make PSRAM a natural choice. Winbond offers a variety of PSRAM densities from 32 Mb to 256 Mb in BGA packages.

Winbond’s PSRAM Product Features

  • Broad density offering from 32 Mb to 256 Mb

  • Operating voltage range: 1.7V to 1.9V

  • Memory organization: x16

  • 133 MHz Clock Rate

  • 70 ns Random Access Time

  • Option for Address Data Multiplex (ADM) to take advantage of less pins or Address Data Parallel (ADP)

  • Standard 54 BGA for all densities, 49 BGA for 64 Mb only

These 1.8V low power devices include a deep, power down sleep mode which help to extend the IoT device’s battery life. Additional features that support less overall power consumption include partial-array self-refresh and configurable drive strengths of ½ and ¼ strength.

Winbond HYPERRAM™ products provide a compact alternative to traditional pseudo-SRAM in IoT and consumer devices, automotive and industrial equipment. The introduction in 2021 of HYPERRAM™ devices produced on Winbond’s 25nm process extends densities up to 256Mb and 512Mb. For package type, HYPERRAM supports 24BGA, WLCSP and KGD.

Ultra-low Power Consumption:
Winbond’s Hybrid Sleep Mode (HSM) gives standby power consumption as low as 35μW, and operating power less than half that of equivalent pSRAM products.
Design Simplicity:
HYPERRAM™ devices use just 13 signal pins, compared to 31 signal pins in pSRAM. This makes the board layout much simpler to design and manufacture.
Space-saving:
Low pin-count packages and a lower number of connections to the host controller reduce the memory system’s board footprint and save space in consumer devices such as smart watches.
