FAQ
What is the memory organization and total capacity of SST39VF3201-70-4I-B3KE-T?
The SST39VF3201-70-4I-B3KE-T is organized as 2M × 16, delivering 32 Mbit (4 MB) of nonvolatile storage. Its address range spans 000000H to 1FFFFFH, with A0–A19 used for addressing and A20 serving as the most significant bit. This structure supports direct x16 bus interfacing without byte-swapping logic, and is explicitly confirmed in DS25028A Section 1 and Table 9 for SST39VF3201/3202 devices.
Does SST39VF3201-70-4I-B3KE-T support hardware write protection, and how is it implemented?
Yes, the SST39VF3201-70-4I-B3KE-T implements bottom-block hardware write protection via the WP# pin. When WP# is driven low, the bottom 32 KWord (000000H–007FFFH) - the boot block - is locked against program and erase operations. This is distinct from SST39VF3202, which protects the top block. The behavior is documented in DS25028A Tables 3 and 5, and confirmed by pin function description in Table 1.
What package type and footprint does SST39VF3201-70-4I-B3KE-T use?
The SST39VF3201-70-4I-B3KE-T uses a 48-ball TFBGA package with B3K footprint (6 mm × 8 mm, balls facing down), as shown in Figure 3 of DS25028A. It is not offered in TSOP; the "B3KE" suffix explicitly denotes the TFBGA variant. Pin assignments match JEDEC-standard x16 flash layouts, with dedicated VSS balls at E1 and H1 for noise immunity.
How does SST39VF3201-70-4I-B3KE-T indicate completion of program or erase operations?
The SST39VF3201-70-4I-B3KE-T provides two concurrent status detection methods: Data# Polling on DQ7 (complement-to-data during operation, true data upon completion) and Toggle Bit on DQ6 (toggles between 0/1 during operation, stops toggling when complete). Both are valid after the rising edge of the sixth WE# pulse for erase and fourth for program, per DS25028A Sections 7 and 8.
Is SST39VF3201-70-4I-B3KE-T still recommended for new designs?
No - DS25028A Rev. 08/11 explicitly states "Not Recommended for New Designs" and recommends SST39VF3201B instead. However, SST39VF3201-70-4I-B3KE-T remains fully supported for existing designs, with guaranteed parametric performance, full documentation, and active supply chain management through Aetrix Electronics for legacy system maintenance and repair.
