The 70 ns access time means the part can keep up with moderate-speed MCUs and DSPs without inserting wait states on random reads — a key fit criterion for direct-execution firmware, not just data logging. Housed in a 48-ball WFBGA (6 mm x 4 mm) with a 0.50 mm ball pitch, this package demands careful PCB layout — the fine pitch and exposed die paddle require a controlled solder-paste stencil and a reflow profile matched to the JEDEC moisture sensitivity level of the part. Supplied on tape and reel, the part is ready for automated pick-and-place assembly in volume production. ## Write-cycle budget and firmware updates The page write cycle time is 20 µs — a full 512 KB sector rewrite at the page level takes roughly 20 ms, which is fast enough for in-field firmware updates over a UART or CAN bootloader without a dedicated flash programmer. Because it is a NOR flash, the random-read speed (70 ns) is the same as the byte-wide read access — no page-buffer penalty on scattered reads, which matters when the CPU fetches interrupt vectors or lookup tables from arbitrary addresses.","metaTitle":"SST39VF800A-70-4I-MAQE-T 8Mbit Parallel NOR Flash, 70ns","metaDescription":"Microchip Technology SST39VF800A-70-4I-MAQE-T 8Mbit parallel NOR flash, 70ns access time, 48-WFBGA, -40 to 85°C, active production.
