MT25QL128ABA8ESF-0SIT - 128Mbit SPI/Quad-SPI NOR Flash | Micron
MPN: MT25QL128ABA8ESF-0SIT ✓ نشطMT25QL128ABA8ESF-0SIT نظرة عامة
A NOR flash memory is a non-volatile storage technology where each cell behaves like a MOSFET with a floating gate, giving byte-level random read access and faster read latency than NAND, at the cost of lower density and slower write/erase. NOR fits into the broader hierarchy of memory ICs (volatile DRAM/SRAM -> non-volatile flash -> storage class memory), and within flash, the serial NOR sub-family delivers code storage and execute-in-place capability to microcontrollers, SoCs, and FPGAs that lack large internal flash.
Key features of the MT25QL128ABA8ESF-0SIT include 4 KB sub-sector erase granularity alongside 32 KB and 64 KB sector erase commands, hardware and software write protection via status-register bits, a deep power-down mode that drops standby current below typical levels, and JEDEC-standard SFDP (Serial Flash Discoverable Parameters) for auto-configuration by the host. The -0SIT speed grade designates 133 MHz operation in industrial -40C to +85C temperature range.
The die uses a single supply rail with internal charge-pump-generated high voltage for program/erase operations, and supports continuous read across the full linear address map. The device also offers volatile and non-volatile status register locking, allowing the host to commit configuration bits either temporarily or permanently across power cycles.
Typical applications include boot-loader storage for ARM Cortex-M/R microcontrollers, firmware shadowing for Linux SoCs, configuration parameter retention in industrial PLCs, asset-tracking dataloggers, and FPGA bitstream storage. The wide operating voltage and Quad-SPI throughput also suit battery-backed appliances and metering devices.
When designing, observe JEDEC JESD22-A114 ESD and IPC-7351 land-pattern guidelines, route the SCK line with impedance control to limit ringing above 80 MHz, and place a 0.1 uF decoupling capacitor within 3 mm of the VCC pin. Verify SFDP header alignment with the host controller's QSPI peripheral before locking the PCB layout.

التطبيقات النموذجية
MT25QL128ABA8ESF-0SIT مناسب لـ 6 التطبيقs: Microcontroller Boot Flash, FPGA Bitstream Storage, Industrial IoT Gateway Firmware, Configuration and Parameter Retention, Asset Tracking and Datalogger, Display and HMI Boot + Asset Storage.
Microcontroller Boot Flash
The MT25QL128ABA8ESF-0SIT stores boot loaders and application firmware for Cortex-M7, RISC-V, and Cortex-A SoCs that lack sufficient internal flash. Its 128 Mbit (16 MB) capacity fits typical RTOS plus application images of 4-8 MB with headroom. Quad-SPI at 133 MHz yields 60+ MB/s sequential read, enabling execute-in-place (XIP) boot in well under 200 ms. The 6 ns access time keeps cache-miss latency tight, and the JEDEC SFDP header lets the host QSPI peripheral auto-configure clocks, dummy cycles, and protocol mode at boot without firmware intervention. Industrial -40 to +85 C grading suits outdoor controllers.

FPGA Bitstream Storage
FPGAs and SoC FPGAs (e.g. Xilinx Zynq, Intel Cyclone) typically store configuration bitstreams in external serial NOR flash. The MT25QL128ABA8ESF-0SIT's 128 Mbit density supports mid-density FPGAs up to Lattice ECP5, Xilinx Artix-7, and Intel Cyclone V bitstreams. Quad-SPI mode at 133 MHz compresses configuration time, while 4 KB sub-sector erase granularity lets designers store multiple bitstream images for safe fallback updates. The 100,000-erase endurance and 20-year retention comfortably handle hundreds of OTA updates over a typical product lifetime.
موصى به
Industrial IoT Gateway Firmware
Industrial IoT gateways need reliable, field-upgradable firmware storage across -40 to +85 C environments. The MT25QL128ABA8ESF-0SIT's industrial temperature grade, 100,000-erase cycles per sector, and 20-year retention fit years of OTA firmware updates on factory floors. Quad-SPI throughput keeps image fetch fast at boot, while the deep power-down mode drops quiescent current for battery-backed gateway operation. AEC-Q100 is not required for non-automotive industrial gateways, so the -0SIT (vs -0AAT) saves cost.
موصى به
Configuration and Parameter Retention
In test equipment, instrumentation, and metering devices, calibration constants, factory settings, and event logs need persistent storage that survives power cycles and field updates. The MT25QL128ABA8ESF-0SIT provides 128 Mbit of non-volatile storage with 4 KB sub-sector erase - perfect for storing many small configuration blocks. The hardware write-protect pin lets a service-mode pin lock the calibration region while leaving user logs writable. Status register protection prevents accidental block protection changes by runaway firmware.
موصى به
Asset Tracking and Datalogger
Battery-powered asset trackers and environmental dataloggers log sensor samples to external flash between BLE/WiFi transmissions. The MT25QL128ABA8ESF-0SIT's deep power-down mode drops standby current to microamps, conserving battery, while 128 Mbit fits weeks to months of timestamped samples at low sample rates. The fast Quad-SPI wake-and-burst read lets the host MCU drain the log quickly before retransmission. Industrial temperature grading handles outdoor deployments in logistics and cold-chain monitoring.
موصى به
Display and HMI Boot + Asset Storage
HMI panels and digital signage controllers boot RTOS images and store graphical assets, fonts, and translation strings in external flash. The MT25QL128ABA8ESF-0SIT supports XIP boot and bulk-asset storage in one chip, eliminating a parallel NAND chip. Quad-SPI keeps asset-fetch latency low so the UI does not stall on icon/bitmap loads. The wide 2.7-3.6 V supply range tolerates the noisy 3V3 rails typical in backlight-driven panels.

ملاحظات التصميم
Place a 0.1 uF X7R decoupling capacitor within 3 mm of the VCC pin (pin 8) and a 10 uF bulk capacitor on the same supply rail. The SCK trace should be routed with 50 ohm characteristic impedance to limit ringing when operating at 80 MHz or higher. Per IPC-7351, follow the SO-16 land pattern with no via-in-pad under the package body.
When operating the part in Quad-SPI mode above 80 MHz, series-terminate SCK with a 33 ohm resistor near the host driver to damp overshoot. The IO0-IO3 lines should be length-matched to within 50 mil of SCK to keep skew below 250 ps. Keep CS# rise/fall times below 5 ns - a 10 kohm pull-up to VCC is recommended when the host releases the bus.
Do not skip the SFDP header read during host bring-up; default read settings (single-wire SPI, 50 MHz, 8 dummy cycles) differ across vendors and Micron parts specifically use 6 dummy cycles at 133 MHz. A wrong dummy-cycle count manifests as garbage data on first reads. Verify the JEDEC manufacturer ID (0x20) before issuing program/erase commands.
Active read current at 133 MHz Quad-SPI is approximately 25 mA typical; deep power-down drops this below 10 uA. Program and erase operations draw up to 35 mA - budget the host LDO or DC-DC headroom accordingly. A 10 uF bulk + 0.1 uF decoupling pair is mandatory for sustained erase operations to prevent VCC droop triggering POR.
