At 2.7 V minimum supply, the access time is still 70 ns — no derating at the low end of the voltage range. This matters for a legacy 8-bit microcontroller that expects a 70 ns or faster memory window; if the bus cycle is 100 ns, this part meets it with 30 ns of margin. The parallel interface means eight address/data lines share the bus — no serial translation logic needed. The 20 µs page write cycle lets you program a full page in one operation, which speeds up firmware updates compared to byte-by-byte writes. ## 32-PLCC package — board-fit and rework considerations The 32-PLCC (J-Lead) package with a body size of 11.43 x 13.97 mm is a through-hole-solderable surface-mount footprint. The J-leads are on a 1.27 mm pitch, which is hand-solderable with a fine tip but much easier with a hot-air station. The PLCC socket (if used) adds height — the bare chip sits about 3.5 mm above the board. ## Industrial temperature grade and supply range No AEC-Q grade is cited, so it is not qualified for automotive under-hood use. ## Sourcing posture and compliance documentation Active lifecycle means this is available through authorized distribution channels. Quoted to order per RFQ — no stock claim, no lead-time number. ROHS3 compliant, which covers the full RoHS exemption list including lead in solder.","metaTitle":"Microchip SST39VF020-70-4I-NHE 2Mbit Parallel Flash, 70 ns","metaDescription":"Active 2Mbit parallel NOR flash in 32-PLCC. 70 ns access time, 2.7-3.6V, -40°C to +85°C.
