The AT45DB161E-SHFHA-T is a 16 Mbit SPI NOR flash from Renesas, organized as 528 bytes x 4096 pages. Page write time is 8 µs typical; sector erase completes in 4 ms. That combination makes OTA firmware updates viable — the host can stream a new image without blocking on flash erase cycles. Industrial temperature range -40°C to 85°C (TC) means it operates reliably in outdoor telecom cabinets, motor-drive enclosures, and under-hood automotive modules without a heater or active cooling.
Package and board-fit — 8-SOIC narrow body
Housed in an 8-SOIC (0.209", 5.30 mm width) package, the AT45DB161E-SHFHA-T uses a common footprint that reflows on standard lead-free profiles. The supplier device package is 8-SOIC — same land pattern as many other SPI flash parts, so a board spin for a second source is minimal.
Lifecycle and compliance — active, ROHS3, no EOL watch
Renesas lists this part as Active. The part ships with full material declaration for EU and UKCA markets.
