Product details
Overview
SST39VF3202-70-4C-B3KE from Microchip Technology is a 32 Mbit (2M × 16) Multi-Purpose Flash Plus (MPF+) memory IC with CMOS SuperFlash technology, 70 ns read access time, single 2.7–3.6 V supply operation, and top-block hardware write protection. It supports sector/block/chip erase, erase-suspend/resume, and security ID programming for embedded firmware storage in industrial controllers and legacy communication modules.
For engineers reviewing the SST39VF3202-70-4C-B3KE datasheet, SST39VF3202-70-4C-B3KE pinout, SST39VF3202-70-4C-B3KE application, or SST39VF3202-70-4C-B3KE equivalent, this page delivers verified flash timing, JEDEC-compliant x16 interface behavior, top-boot block protection mapping, and real-world erase/program performance metrics - all confirmed against DS25028A Rev A.
Technical Context
The SST39VF3202-70-4C-B3KE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed 18 ms sector/block erase and 7 µs word-program times independent of cycle count. Its JEDEC-standard x16 asynchronous interface uses CE#, OE#, and WE# control lines with latched address/data buses and tri-state outputs.
Hardware block protection targets the top 32 KWord (1F8000H–1FFFFFH) via WP# pin grounding; RST# provides hardware reset to Read mode; and CFI query support (0x5555H + 0x98H) enables runtime device identification and geometry detection in bootloaders.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
48-ball TFBGA package (B3K suffix), ball grid layout per DS25028A Figure 3, top view with balls facing down. Pin functions conform to JEDEC-standard x16 flash pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | A0–A19 used for 2M×16 addressing; A20 selects upper half of 32 Mbit array (1F8000H–1FFFFFH) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched during write; tri-state when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write operations |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read cycles only |
| WE# | Write Enable | Active-low control for program/erase command latching and internal timing initiation |
| WP# | Write Protect | Grounded to lock top 32 KWord boot block; floating = unprotected (internal pull-up) |
| RST# | Reset | Hardware reset input; forces return to Read mode within TRP (min 100 ns) |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; dual ground pins for noise reduction in high-speed reads |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary read access during active sector/block erase - critical for real-time OS interrupt handling |
| Security ID Space | 256-bit factory + user programmable ID (128+128 bits), locked after programming to prevent tampering |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts standby power in always-on systems |
| Software Data Protection | JEDEC-compliant 3-byte (program) or 6-byte (erase) command sequences prevent spurious writes during power transitions |
| CFI Query Support | Enables automatic detection of device geometry, timing parameters, and command set via standardized 0x5555H + 0x98H entry |
Applications
| Industrial PLC Firmware Storage | Legacy Telecom Baseband Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201B | Bottom-block protection (000000H–007FFFH); same density, timing, and package options | Used where boot code resides in lowest memory region instead of top region | Select when legacy design requires bottom-boot architecture and newer revision (B suffix) is preferred |
| MX29LV320ETTI-70G | 32 Mbit x16, 70 ns, but uses different command set (no CFI query) and lacks erase-suspend capability | Requires modified driver software; no real-time suspend/resume during erase | Choose only if existing firmware already supports Macronix command protocol and suspend functionality is unused |
Compared with SST39VF3202-70-4C-B3KE, SST39VF3201B offers identical performance with inverted block protection location, while MX29LV320ETTI-70G sacrifices CFI and erase-suspend for broader distributor availability - making SST39VF3202-70-4C-B3KE optimal for new designs needing top-boot security and real-time firmware management.

FAQ
What is the exact memory organization of the SST39VF3202-70-4C-B3KE?
The SST39VF3202-70-4C-B3KE is organized as 2M × 16 bits (32 Mbit total), with address range 000000H–1FFFFFH. It uses A0–A19 for standard addressing and A20 to access the upper half of the array. This matches the top-boot configuration specified in Table 3 of DS25028A for SST39VF3202 devices.
Does the SST39VF3202-70-4C-B3KE require an external VPP voltage for programming?
No, the SST39VF3202-70-4C-B3KE does not require external VPP. It generates internal high-voltage programming pulses using its on-chip charge pump, operating entirely from the 2.7–3.6 V VDD supply. This is confirmed in the "Automatic Write Timing" feature and Table 8 (VPP min/max = 0000H) of DS25028A.
How is hardware write protection implemented on the SST39VF3202-70-4C-B3KE?
Hardware write protection on the SST39VF3202-70-4C-B3KE is enabled by grounding the WP# pin, which locks the top 32 KWord block (1F8000H–1FFFFFH). When WP# is left floating, an internal pull-up holds it high, disabling protection. This behavior is explicitly defined in the "Hardware Block Protection" section and Table 3 of DS25028A.
What is the purpose of the RST# pin on the SST39VF3202-70-4C-B3KE?
The RST# pin on the SST39VF3202-70-4C-B3KE provides hardware-initiated reset to Read mode. Holding RST# low for ≥100 ns (TRP) terminates any ongoing program or erase operation and returns the device to ready state. After release, a minimum TRHR delay (≥100 ns) is required before valid reads resume - details are in the "Hardware Reset (RST#)" section of DS25028A.
Is the SST39VF3202-70-4C-B3KE still recommended for new designs?
No - the SST39VF3202-70-4C-B3KE is marked "Not Recommended for New Designs" in DS25028A. Microchip recommends migrating to SST39VF3201B for bottom-boot variants or evaluating newer serial NOR alternatives. However, SST39VF3202-70-4C-B3KE remains supported for existing designs and legacy replacements with full datasheet compliance.
