The 16 Mbit (x8) Multi-Purpose Flash Plus SST39VF1681 / SST39VF1682 is a high-reliability, low-power consumption storage chip that supports single-voltage read and write operations and is suitable for a variety of portable electronic devices.
These 16‑Mbit (2M × 8) Flash Plus devices operate from 2.7 V to 3.6 V and provide high reliability with 100,000‑cycle endurance and over 100‑year data retention. They feature low active current (9 mA typical) and ultra‑low standby current (3 µA typical) with an auto low‑power mode.
The devices support sector, block, and chip erase, fast byte‑program, and hardware/software data protection. Pinouts follow JEDEC standards and are offered in 48‑ball TFBGA (6 mm × 8 mm) and 48‑lead TSOP (12 mm × 20 mm) packages. Detailed command sequences for read, program, erase, and security‑ID operations are provided.
