Nor Flash
The NOR Flash Memory forum discusses critical safety features for automotive and industrial systems, and Semper NOR Flash Memory with ASIL-B compliant and ASIL-D-ready.
Hyper Flash
The HyperFlash NOR Flash memories Forum offers discussions on automotive advanced driver assistance systems (ADAS), automotive instrument cluster, automotive infotainment systems, and communication equipment.
Hyper RAM
HyperRAM™ memory Forum discusses self-refresh DRAM operating on the 12-pin HyperBus interface. With a read throughput up to 333 MB/s, the HyperRAM for SoCs with limited on-board RAM providing external scratch-pad memory for fast read and write operations.
Non Volatile RAM (F-RAM & NVSRAM)
Non-volatile RAM forum discusses Technology such as F-RAM and nvSRAM, which combine non-volatile data storage up to 16Mbit density with the high performance of RAM. These low-power memories offer high endurance, high data retention and instant non-volatility without external battery back-up, enabling system reliability and cost reduction.

The user use the Hyper Flash S26KS128SDPBHB020; Could you tell me the init program of S26KS128SDPBHB020; Dose the S26KS128SDPBHB020 need the "init program" that was translated by the Controller through "Hyper" or "SPI"? 此型号Flash在使用的时候,需要Init 程序吗 ?在哪儿下载呀 非常感谢
Thanks
Show LessI'm currently reviewing the S25FL512S to be used as a QSPI device. Looking through the data sheet I can see a rise and fall time slew rate specified for the clock. Are there any rise and fall time specifications for any of the data lines or the chip select line? Under the AC test measurement conditions I can see a maximum Input Rise and Fall time of 2.4 ns listed, but that's about all I can find.
Show LessHello,
We are developing battery operated device with u-blox NORA-B106-10B (ESP32-S3) module as a MCU. Due to large flash (64 Mbit) project requirement, we have selected Infenion S25FL064L (S25FL064LABMFI013) flash connected over SPI interface.
As per ESP-IDF docuement, (esp_deep_sleep_start()
) function will force power down flash regardless of user configuration.
As per our testing observation with ESP32-S3-WROOM-1 (It has external 64Mbit SPI flash memory. Sorry, Not sure about Flash memory vendor part number), we could put SPI flash memory in sleep mode and takes less than 1 mA.
Same test we have also performed with u-blox NORA-B106-10B and Infenion S25FL064L (S25FL064LABMFI013) flash memory in our prototype hardware. It takes around 10-12 mA current consumption when MCU in sleep mode (lowest power mode of ESP32-S3). It means, S25FL064L couldn't switch to power down mode when MCU in sleep mode.
Looking forward for your response. Thanks in advance.
Show LessIs there any sample code or user guide for S70KS1283GABHI023 to program?
Hi
What does Mode “2” mean for Quad I/O Read in Latency codes of Table 24 ?
Please find attachment file.
Does that mean the “number of clocks” of mode bits ?
Additionally the mode bits should be equal to Axh ?
Best regards,

S25FL064L write and read data to non volatile memory please give me the write and read data command array for the eeprom.
n
I was use below coomand for the write the data to page but when i wanna read the data for this register not get the value
give me some solution for this epprom or provide any additional information.
i am going to the data sheet but this thigs i was little bit confuse.
write enable -0x06e
write page 0x02 address 0x0000000 data 0x1234.
write disable 0x04
read register 0x03 address 0x0000000

- We are interfacing Parallel NOR Flash (S29GL256P) with our MCU. It should be usable in both 8 & 16 bit modes
- MCU address lines: M_A23 - M_A0 (M_A0 is always LSB)
- NOR Flash address lines: A23 - A0 (16 bits) + A-1 (LSB for 8-bit mode)
- Connection for 16 bit mode: M_A0 to A0
- Connection for 8-bit mode: M_A0 to A-1
1. Is the above understanding correct?
2. Depending on 8/16 bit mode the MCU lines connect to different pins. Does this shift in address lines need to handled by software?
3. In 8-bit mode, the MCU M_A0 pin connects to NOR A-1 pin. Is this understanding correct? Or can we leave DQ15/A-1 just connected to the data line (Not connected to any address line)?
