The "MX25L12835FMI-10G" refers to a product manufactured by Macronix International Co., Ltd., which is a semiconductor company specializing in memory products. This specific part is a flash memory device (likely a NOR flash) with specific performance and interface characteristics. The "-10G" suffix indicates the speed grade of the device, where "-10" often corresponds to a certain access time and "G" typically refers to a particular package or process option.
Since you are looking for detailed specifications, including the pin function, packaging information, and a thorough FAQ, I can provide a general outline and guide for these aspects based on typical practices, but for the most detailed and specific pinout and datasheet information, you should refer directly to Macronix's official datasheet for the MX25L12835FMI-10G.
Pinout Details:
Typically, the MX25L12835FMI-10G is housed in a WSON (8mm x 6mm) package or similar, with 8 pins, depending on the packaging variation, but specific configurations such as LQFP (Low Profile Quad Flat Package) or BGA (Ball Grid Array) are possible as well.
Here’s a basic outline of the pinout for a flash memory IC (which may be similar to your part):
Pin Number Pin Name Function Description 1 CS# Chip Select, active low, used to enable the chip for communication. 2 WP# Write Protect, used to disable write operations (active low). 3 VSS Ground pin, connects to the system ground. 4 VCC Power supply pin, typically +3.3V or +1.8V, depending on the specific part. 5 SCK Serial Clock , used for SPI communication to clock in data. 6 SI Serial Input, used to send data to the device (MOSI in SPI). 7 SO Serial Output, used to send data from the device (MISO in SPI). 8 HOLD# Hold Pin, used to pause the SPI communication (active low).This is a simplified example of the pinout. Please note that your device might have different packaging and pin configurations, especially if it's in a different package like BGA or LQFP, so it's critical to consult the official datasheet for the exact pinout.
Detailed FAQ (20 Common Questions and Answers):
What is the purpose of the CS# pin in the MX25L12835FMI-10G? The CS# pin is the Chip Select pin. It is used to enable or disable the communication with the memory device. When it is low (active), the device is enabled; when high, the device is disabled.
How do I write data to the MX25L12835FMI-10G? To write data, you need to assert the CS# pin low, send the write command through SI (Serial Input), and clock the data using SCK (Serial Clock). Ensure that WP# is not active (low) as this would disable writing.
Can I use the MX25L12835FMI-10G for both read and write operations? Yes, the device can be used for both read and write operations. You must control the CS#, SCK, SI, and SO pins for SPI communication to perform read and write commands.
What voltage levels does the MX25L12835FMI-10G require? The VCC pin typically requires a voltage between 2.7V and 3.6V, with 3.3V being a common supply voltage for this type of flash memory.
Is the MX25L12835FMI-10G compatible with 1.8V systems? Yes, some variants of the MX25L12835FMI-10G support 1.8V operation, but the exact voltage should be checked in the datasheet for your specific part.
What is the maximum clock frequency for SPI communication? The maximum clock frequency depends on the speed grade of the device. For the -10G version, it can operate up to 80 MHz in standard SPI mode, but this should be confirmed in the datasheet.
**What happens if the *WP#* pin is low?** When the WP# (Write Protect) pin is low, write operations to the memory are disabled, protecting the stored data from accidental modification or erasure.
How can I reset the MX25L12835FMI-10G device? To reset the device, the CS# pin should be deasserted (set high), and then reasserted low to initiate a fresh communication cycle.
Can I use the MX25L12835FMI-10G with I2C communication? No, the MX25L12835FMI-10G operates only with SPI (Serial Peripheral Interface) communication, not I2C.
What is the HOLD# pin used for? The HOLD# pin is used to temporarily pause the SPI communication without deasserting the CS# pin. This is useful if you need to perform other operations without breaking the communication session.
Can I use the MX25L12835FMI-10G for bootloading applications? Yes, this flash memory is suitable for bootloading applications due to its fast read capabilities and stable operation.
What are the read modes available for the MX25L12835FMI-10G? The device supports several read modes, including Standard SPI Read, Fast Read, and Dual Output Fast Read, each offering different data throughput speeds.
What is the data retention of the MX25L12835FMI-10G? The typical data retention time is around 20 years, ensuring that the stored data remains intact for a long time when not powered.
How is data written to the memory? Data is written to the memory by sending a Write Enable command followed by a Program command, which writes data to the specified address.
How can I protect data on the MX25L12835FMI-10G? The device features a Write Protect (WP#) pin that can be asserted low to prevent any writes to the memory, offering a layer of protection for the stored data.
Is the MX25L12835FMI-10G susceptible to radiation? Flash memory, including the MX25L12835FMI-10G, is sensitive to high levels of radiation, but its robustness should be considered for specific applications such as aerospace or other high-radiation environments.
What is the erase block size of the MX25L12835FMI-10G? The erase block size for this device is typically 4KB or 64KB, depending on the specific configuration and mode used.
Can the MX25L12835FMI-10G support dual or quad SPI? Yes, the device supports Dual SPI (DIO) and Quad SPI (QIO) for higher-speed data transfer, depending on the mode selected.
How do I check if the MX25L12835FMI-10G is operating correctly? You can check the status of the memory by reading the Status Register through the SO (Serial Output) pin. If the device is busy, it will indicate this in the register.
What is the expected lifespan of the MX25L12835FMI-10G? The typical lifespan is specified in terms of program/erase cycles, typically around 100,000 cycles per sector.
