FAQ
What is the boot block configuration of the SST39VF802C-70-4C-B3KE-T?
The SST39VF802C-70-4C-B3KE-T implements top-boot block protection covering the 8 KWord address range 7E000H–7FFFFH. This is hardwired behavior confirmed in Table 4 and Table 2 of DS25041A. The WP# pin must be grounded to activate hardware lock on this region. Unlike bottom-boot variants (e.g., SST39VF801C), the SST39VF802C-70-4C-B3KE-T does not protect the lower memory segment.
Does the SST39VF802C-70-4C-B3KE-T support erase-suspend functionality?
Yes, the SST39VF802C-70-4C-B3KE-T supports both Erase-Suspend and Erase-Resume commands (B0H and 30H respectively) as defined in Section 7 of DS25041A. This allows reading from non-suspended sectors or programming other blocks while an erase operation is paused - a key capability for real-time systems requiring concurrent memory access.
What package type is used in the SST39VF802C-70-4C-B3KE-T part number suffix?
The "B3KE-T" suffix in SST39VF802C-70-4C-B3KE-T indicates a 48-lead TSOP package (12 mm × 20 mm) with lead-free (RoHS-compliant) finish and tape-and-reel packaging. This matches Figure 2 and Table 1 in DS25041A, and is distinct from TFBGA or WFBGA variants denoted by other suffixes.
How is end-of-write detection implemented in the SST39VF802C-70-4C-B3KE-T?
The SST39VF802C-70-4C-B3KE-T provides three complementary end-of-write detection methods: DQ6 toggle bit, DQ7 data# polling, and RY/BY# open-drain status output. DQ6 toggles during internal program/erase and stops when complete; DQ7 complements true data until completion; RY/BY# pulls low during operation and releases high when ready - all documented in Tables 3 and 9 of DS25041A.
Is the SST39VF802C-70-4C-B3KE-T compatible with JEDEC-standard x16 flash interfaces?
Yes, the SST39VF802C-70-4C-B3KE-T conforms fully to JEDEC standard pinouts and command sets for x16 parallel flash memories, as explicitly stated on page 2 and page 4 of DS25041A. It supports standard read, word-program, sector/block/chip-erase, and CFI query operations using JEDEC-defined timing and voltage thresholds.
