Product details
Overview
SST39VF3202B-70-4C-B3KE from Microchip Technology is a 32 Mbit (2M × 16) CMOS Multi-Purpose Flash Plus memory IC with single-voltage operation (2.7–3.6 V), 70 ns read access time, top-block hardware write protection (1F8000H–1FFFFFH), and SuperFlash® technology enabling 100,000 program/erase cycles. It serves as nonvolatile program/data storage in embedded boot code applications requiring fast word-program (7 µs typical) and sector/block erase (18 ms typical).
For engineers reviewing the SST39VF3202B-70-4C-B3KE datasheet, SST39VF3202B-70-4C-B3KE pinout, SST39VF3202B-70-4C-B3KE application, or SST39VF3202B-70-4C-B3KE equivalent, key selection considerations include top-boot block protection, JEDEC-standard x16 asynchronous interface, TSOP-48 or TFBGA-48 packaging, Erase-Suspend capability, and CFI-compliant identification.
Technical Context
The SST39VF3202B-70-4C-B3KE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, delivering fixed erase/program timing independent of cycle count. It supports standard microprocessor bus interfacing via CE#, OE#, and WE# control signals, with latched address/data and tri-state outputs.
It executes JEDEC-compliant command sequences for Word-Program, Sector-Erase (2 KWord), Block-Erase (32 KWord), Chip-Erase, and Erase-Suspend/Resume. Status detection uses DQ7 Data# Polling and DQ6/DQ2 Toggle Bits, while hardware protection includes WP#-controlled top-block lock and RST#-initiated hard reset.
Key Specifications

FAQ
What is the exact memory organization of the SST39VF3202B-70-4C-B3KE?
The SST39VF3202B-70-4C-B3KE is organized as 2,097,152 words × 16 bits (2M × 16), totaling 32 Mbit. Its address space spans 000000H to 1FFFFFH, with the top 32 KWord block (1F8000H–1FFFFFH) designated as hardware-protected boot sector. This structure supports direct mapping to 16-bit microprocessor data buses without byte-lane translation.
Does the SST39VF3202B-70-4C-B3KE support both TSOP and TFBGA packages?
Yes, the SST39VF3202B-70-4C-B3KE is available in two RoHS-compliant packages: 48-lead TSOP (12 mm × 20 mm) and 48-ball TFBGA (6 mm × 8 mm). The B3KE suffix specifically denotes the 48-lead TSOP package with commercial temperature grade (0°C to +70°C) and 70 ns access time. Pin functions and command sets are identical across both packages.
How does hardware block protection work on the SST39VF3202B-70-4C-B3KE?
Hardware block protection on the SST39VF3202B-70-4C-B3KE is implemented via the WP# pin. When WP# is driven low, program and erase operations on the top 32 KWord block (1F8000H–1FFFFFH) are disabled. If WP# is left floating, an internal pull-up holds it high, leaving the block unprotected. This mechanism operates independently of software commands and remains active during power transitions.
What status detection methods does the SST39VF3202B-70-4C-B3KE provide for write operations?
The SST39VF3202B-70-4C-B3KE provides two complementary status detection methods: Data# Polling on DQ7 (complement-to-data during write, true data upon completion) and Toggle Bit on DQ6 (toggles between 0/1 during write, stops toggling at completion). DQ2 also toggles during Erase-Suspend operations, enabling precise suspend-state identification during multi-sector updates.
Is the SST39VF3202B-70-4C-B3KE compatible with JEDEC-standard flash interfaces?
Yes, the SST39VF3202B-70-4C-B3KE conforms fully to JEDEC standard pin assignments for x16 asynchronous flash memories (JESD21-C). It supports Common Flash Interface (CFI) query mode via standardized command sequences, enabling automatic detection of geometry, timing, and command set parameters by host BIOS or bootloader firmware.
