• High-Speed Clock  Operates with a clock frequency up to 166 MHz to support fast serial read operations.
• Read/Buffer Modes  Buffer Read and Continuous Read modes are supported for efficient data transfer and sustained read throughput.
• Program/Erase & Bad Block Management  Includes program execute, 128KB block erase and bad block management features as documented in device instruction set.
• Protection & Configuration  Protection, configuration and status registers with OTP-lockable bits and an ECC enable bit for configurable device protection and error reporting.
• Performance Characteristics  Typical access time cited as 7 ns and a write (word/page) cycle time of 700 µs for programming operations.
• Power Supply  Single-supply operation from 2.7V to 3.6V, specified as a 3V device in the datasheet.
• Package & Temperature  Supplied in a 24-TFBGA (6×8 mm) package and specified for operation from -40°C to 85°C (TA).

Typical Applications

• Embedded Firmware Storage  Non-volatile SLC NAND storage for boot code and firmware images requiring organized 64M × 8 memory.
• Serial Data Storage  External serial flash for system data and lookup tables, using Dual/Quad SPI for higher throughput.
• Industrial Control Systems  Use in equipment that benefits from the device’s -40°C to 85°C operating range and compact TFBGA package.
• Consumer and IoT Devices  Code and data storage in space-constrained designs that require a 3V serial NAND flash solution.

Unique Advantages

• Serial SLC NAND Architecture: Provides single-level cell flash organization (64M × 8) for non-volatile data retention and predictable storage layout.
• Flexible SPI Modes: Dual and Quad SPI plus buffer/continuous read modes give designers options to balance pin usage and sustained read performance up to a 166 MHz clock.
• Integrated Protection and ECC Controls: Protection, configuration and status registers with OTP-lockable bits and an ECC enable option enable configurable data integrity and device locking.
• Industrial Temperature Range: Specified operation from -40°C to 85°C supports deployments in temperature-challenging environments.
• Wide Supply Range: 2.7V to 3.6V supply tolerance allows compatibility with common 3V system rails.
• Compact BGA Package: 24-TFBGA (6×8 mm) package offers a small footprint for space-constrained PCB designs.
