SST 1 Mbit 2 Mbit 4 Mbit (x8) Multi-Purpose Flash SST39SF010A SST39SF020A SST39SF040 handbook
The SST39SF010A/020A/040 series are CMOS Multi‑Purpose Flash (MPF) devices built with Silicon Storage Technology's SuperFlash technology. They support 5.0 V read and write operations and are available in 32‑pin PLCC, TSOP and PDIP packages.
Key features include organized densities of 128K‑/256K‑/512K‑x8, uniform 4 KB sectors, fast read access (45‑70 ns), byte‑program time of 14 µs, chip‑erase time of 70 ms, typical active current of 10 mA, standby current of 30 µA, and an endurance of 100 000 cycles with data retention exceeding 100 years.
