W25Q32JVSSIQ IC

W25Q32JVSSIQ General Descriptions

A storage option for devices with little room, power, or pins is the W25Q32JV Serial Flash memory. Beyond what is typically available in Serial Flash devices, the 25Q series offers versatility and performance. They are excellent for storing voice, text, and data and directly executing code from Dual or Quad SPI and code shadowing to RAM. Current usage for power-down is as low as 1 A while the device operates on a 2.7V to 3.6V power source.

Each of the 16,384 programmable pages in the W25Q32JV array has 256 bytes. It is possible to program 256 bytes at once. Pages can be deleted in groups of 16, 128, 256, or the full chip (4KB sector erase, 32KB block erase, 64KB block erase, and chip erase, respectively). The W25Q32JV contains 64 erasable blocks and 1,024 erasable sectors. Applications that need to store data and parameters can operate with more flexibility thanks to the compact 4KB sectors.

W25Q32JVSSIQ Features

• For high-performance serial flash memory applications, the W25Q32JV series of SpiFlash memories offers a number of cutting-edge capabilities. The W25Q32JV is a member of this memory family with a 32Mbit/4Mbyte capacity. It supports the Standard SPI, Dual SPI, and Quad SPI communication protocols and has the following signal inputs: CLK, /CS, DI, DO, IO0, IO1, IO2, and IO3 signals.
• The 133MHz single, dual, or quad and 266 or 532MHz equivalent dual or quad SPI clocks used in the W25Q32JV memory family are intended to deliver exceptional performance. It is the perfect option for high-speed data transfer applications because of its continuous data transfer rate of 66MB/s. The memory family also offers over 20 years of data retention and a minimum of 100K program-erase cycles per sector, ensuring stable performance for a very long time.
• With only 8 clocks needed to access memory, this memory family’s effective “Continuous Read” feature enables continuous read with an 8/16/32/64-byte wrap, enabling genuine XIP (execute in place) operation. High-speed data transfer applications like Continuous Read because it performs better than X16 Parallel Flash.
• Both advantages are the -40°C to +85°C operational range and low power consumption of the W25Q32JV memory family. It is energy-efficient and appropriate for applications that need for low power consumption because it just requires a single 2.7V to 3.6V supply and uses less than 1A power-down (typically).
• The memory family features an adaptable architecture with 4KB sectors, provides uniform sector or block erase, and programs up to 256 bytes per programmable page. It is a great option for applications needing flexible architecture and effective operation because it offers erase/program suspend and resume.
• The W25Q32JV memory family is equipped with cutting-edge security features, including as hardware and software write-protect, unique OTP protection, top or bottom complement array protection, and individual block or sector array protection. It has 3X256-Bytes Security Registers, a discoverable parameter register, a 64-bit unique ID for each device, and a 64-bit unique ID for the system. Furthermore, it has volatile and non-volatile status register bits, which makes it highly secure and appropriate for applications that need sophisticated security features.

W25Q32JVSSIQ Functional Descriptions

● Standard SPI Instructions

An SPI-compliant bus with four signals—Serial Clock (CLK), Chip Select, Serial Data Input (DI), and Serial Data Output (DO)—allows access to the W25Q32JV. Standard SPI instructions use the DI input pin to serially write instructions, addresses, or data to the device on the rising edge of CLK. On the falling edge of CLK, the device is ready for data or status using the DO output pin. There is support for SPI bus operation modes 0 (0,0) and 3 (1,1).

The typical status of the CLK signal while the SPI bus master is on standby and no data is being transferred to the Serial Flash is the main difference between Modes 0 and 3. The CLK signal is typically low on the falling and rising edges of /CS for Mode 0. On the falling and rising edges of /CS, the CLK signal for Mode 3 is typically high.

● Dual SPI Instructions

Utilizing commands like “Fast Read Dual Output (3Bh)” and “Fast Read Dual I/O (BBh)” will enable Dual SPI operation on the W25Q32JV. Thanks to these instructions, data can be transferred to or from the device at a pace that is two to three times faster than with typical Serial Flash devices. The Dual SPI Read instructions are excellent for immediately running non-speed-critical code from the SPI bus (XIP) or swiftly downloading code to RAM upon power-up (code-shadowing). The DI and DO pins change to IO0 and IO1 bidirectional I/O pins when Dual SPI instructions are used.

● Quad SPI Instructions

When using instructions like “Fast Read Quad Output (6Bh)” and “Fast Read Quad I/O (EBh),” the W25Q32JV supports Quad SPI operation. Data can be sent four to six times as quickly with these instructions than with regular Serial Flash. The DI and DO pins are converted to bidirectional IO0 and IO1 when employing Quad SPI instructions, and two extra I/O pins—IO2 and IO3—are added.

● Hardware and Software Reset  or RESET pin

Using a software Reset procedure, the W25Q32JV can be returned to the initial power-on condition. Enable Reset (66h) and Reset (99h) are instructions that must follow each other in this sequence. If the instruction sequence is accepted successfully, it will take about 30 s (tRST) to reset the device. During the reset period, no instructions will be honored. W25Q32JV provides a specific hardware /RESET pin for the SOIC-16 and TFBGA packages. Any ongoing internal or external operations will be stopped, and the device will be brought back to its initial power-on state if you drive the /RESET pin low for at least one second (tRESET*). Other SPI input signals (/CS, CLK, and IOs) have lower priority than the hardware reset pin (/RESET).

Conclusion

Finally, the W25Q32JV memory family provides a sophisticated and adaptable solution for high-performance serial flash memory applications. It is a fantastic solution for energy-efficient, long-term, and safe applications because of its many advantages, including flexible programming and wiping choices, low power consumption, wide temperature range, and advanced security features.
