2 Gbit SLC NAND in a 48-TSOP footprint
The Winbond W29N02KVSIAF TR is a 2 Gbit SLC NAND flash memory in a 48-TSOP package, organized as 256M x 8 bits with a parallel interface. The 20 ns access time suits code-shadowing and data-logging applications where the host controller reads directly from the flash bus without a DRAM cache. SLC NAND delivers higher endurance and faster program/erase cycles than MLC or TLC alternatives — the 25 ns write cycle time per page reflects the single-level cell architecture's inherent speed advantage. For designs that cycle through firmware updates or store telemetry in the field, SLC avoids the wear-leveling overhead that denser NAND grades require.
Supply voltage and temperature grade
The 48-TSOP footprint (0.724" body width) is a standard NAND package — the pinout matches legacy parallel-NAND controllers from NXP, STMicroelectronics, and Microchip. Board layout re-use from an older 1 Gbit or 512 Mbit SLC NAND is straightforward as long as the supply decoupling and signal routing follow the 48-TSOP land pattern.
ROHS3 compliant, which covers the EU RoHS exemption list through 2024. No AEC-Q100 or automotive-grade qualification is stated in the available documentation.
