IS25CQ032-JFLE-TR

Memory

IS25CQ032-JFLE-TR is a family of Quad SPI Serial Flash Memories with extended voltage and temperature range, the Quad SPI operates at higher data transfer rates than the traditional Serial Peripheral Interface (SPI) memory. This memory is ideal for applications which require a high-speed data transfer interface, low-voltage non-volatile memory and an extended temperature range.

IS25CQ032-JFLE-TR application field

The IS25CQ032-JFLE-TR memory is widely used in various types of applications, such as consumer electronics, communication system, car audio and video, GPS navigation, industrial control, instrumentation, medical systems, military applications, automotive systems and so on. It is designed to meet the storage needs in consumer electronics, industrial control and embedded systems, which require both high performance and low power consumption. Also, it supports a wide temperature range of -40 to +125 °C, which is suitable for extreme temperature conditions and ensures long-term storage device reliability.

IS25CQ032-JFLE-TR working principle

IS25CQ032-JFLE-TR memory works under the Quad SPI protocol, which uses clock and four communication lines to interact between flash memory and the host system. In Quad SPI protocol, the Write Enable (WE#) signal on the Quad I/O bus is used to activate the write cycle. The chip select (CS#) signal can be driven low to select the device and then the I/O signals are used to select the read/write operation. The address and data are then transferred serially on the fourth I/O line (DI/O line) while the clock signal is provided on the first I/O line (SCLK). The operation is performed under the control of the Instruction set. The following is a quick overview of the working principle of Quad SPI.

• The host system issues the instruction set to the IS25CQ032-JFLE-TR device through the four serial I/O signals.
• The device responds to the instruction by initiating the appropriate function that matches the instruction.
• The host system sends the user data or address to the device serially with the clock signal provided through the four serial I/O signals.
• The device performs the operation according to the instruction sent by the host system.
• The host system returns the devices status and data to the host system.
