Product details
Overview
SST39VF1602-70-4C-B3KE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with 70 ns read access time, single 2.7–3.6 V supply operation, and top 32 KWord hardware block protection. It supports sector-, block-, and chip-erase modes, erase-suspend/resume, and Security-ID functionality. Used in embedded firmware storage for industrial controllers and legacy communication modules requiring nonvolatile code retention.
For engineers reviewing the SST39VF1602-70-4C-B3KE datasheet, SST39VF1602-70-4C-B3KE pinout, SST39VF1602-70-4C-B3KE application, or SST39VF1602-70-4C-B3KE equivalent, this page delivers verified electrical parameters, JEDEC-compliant x16 interface behavior, TSOP-48 and TFBGA-48 package mapping, boot-block protection logic, and real-world flash management timing constraints - all confirmed against DS25028A Rev A.
Technical Context
The SST39VF1602-70-4C-B3KE implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of cycle count. Its command-set architecture conforms to JEDEC-standard x16 flash pinouts and uses toggle-bit (DQ6/DQ2) and data-polling (DQ7) for write-status detection.
Hardware block protection is activated via WP# grounding to lock the top 32 KWord (0F8000H–0FFFFFH), while RST# provides asynchronous hardware reset to Read mode. The device supports CFI query mode, Software Product ID, and 256-bit Security ID (128-bit factory + 128-bit user programmable), all accessible via standardized three- to six-byte command sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization), delivering 2 MB of addressable nonvolatile storage |
| Read Access Time | 70 ns maximum - determines minimum bus cycle time for CPU read operations |
| Supply Voltage | 2.7–3.6 V - enables direct interfacing with 3.3 V logic systems without level shifting |
| Endurance | 100,000 program/erase cycles - defines field-replaceable firmware update lifetime |
| Data Retention | Greater than 100 years - ensures long-term reliability in unpowered storage applications |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - enables fine-grained firmware patching and recovery partitioning |
| Write Protection | Top 32 KWord hardware block protection via WP# pin - prevents accidental overwrite of boot code |
Pinout & Package
Package: 48-ball TFBGA (6 mm × 8 mm, B3K footprint) per Figure 3 and DS25028A p.4. Pinout validated from official pin assignment diagrams and Table 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A19 used for full 1M×16 addressing; AMS = A19 selects sector/block during erase |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus with internal latching; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select - must be low to enable read/write; controls address/data latch timing |
| OE# | Output Enable | Active-low output gate - enables data output only when CE# and OE# both low |
| WE# | Write Enable | Controls write strobe timing; falling edge latches address, rising edge latches data |
| WP# | Write Protect | Grounded to protect top 32 KWord boot block; internally pulled high if floating |
| RST# | Reset | Hardware reset input - forces return to Read mode; terminates in-progress erase/program |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; dual VSS pins ensure stable reference for 16-bit I/O |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary interruption of sector/block erase to read or program other regions - critical for real-time firmware updates |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts standby power in battery-backed systems |
| Security ID | 256-bit space (128-bit factory + 128-bit user) with lock-out capability - enables secure device authentication and firmware binding |
| CFI Support | JEDEC-standard Common Flash Interface - enables automatic driver detection and configuration in OS/bootloader environments |
| SuperFlash Reliability | Fixed erase/program times unaffected by wear - eliminates software de-rating and simplifies timing-critical firmware design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Bottom 32 KWord hardware protection; same density, voltage, and timing; newer revision with improved ESD rating | Requires PCB layout change to relocate protected region from top to bottom block | Select for new designs where boot code resides in lower memory and enhanced robustness is required |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks Security ID and CFI support | No hardware boot-block protection; relies on software locking - less secure for field updates | Choose when migrating from SST parts and CFI/Security ID features are not needed |
Compared with SST39VF1602-70-4C-B3KE, SST39VF1601C offers updated reliability specs and bottom-block protection for new designs, while MX29LV160ETTI-70G provides functional equivalence without security or standardized query features - making it suitable only where legacy compatibility or cost dominates over firmware integrity requirements.

FAQ
What does the "B3KE" suffix indicate in SST39VF1602-70-4C-B3KE?
The "B3KE" suffix denotes the 48-ball TFBGA package (B3K) with lead-free, RoHS-compliant finish (E). This matches the official Microchip package code for the 6 mm × 8 mm TFBGA variant shown in DS25028A Figure 3 and pinout table. SST39VF1602-70-4C-B3KE is functionally identical to the TSOP-48 version except for physical packaging and thermal characteristics.
Does SST39VF1602-70-4C-B3KE support JEDEC-standard commands and pinouts?
Yes, SST39VF1602-70-4C-B3KE fully conforms to JEDEC standard pinouts for x16 flash memories and implements the industry-standard command set for read, program, sector/block/chip erase, and status polling. This is explicitly stated in DS25028A Section 1 and Table 5, ensuring interoperability with existing flash controllers and boot ROM drivers.
How does hardware block protection work on SST39VF1602-70-4C-B3KE?
SST39VF1602-70-4C-B3KE implements top 32 KWord hardware block protection: when WP# is grounded, program and erase operations are disabled for addresses 0F8000H–0FFFFFH. If WP# floats, an internal pull-up holds it high, disabling protection. This behavior is documented in DS25028A Section 9 and Table 3, distinguishing it from SST39VF1601's bottom-block scheme.
Can SST39VF1602-70-4C-B3KE be used in new designs despite "Not Recommended" status?
While Microchip marks SST39VF1602-70-4C-B3KE as "Not Recommended for New Designs" in DS25028A, it remains fully supported and available for production use in legacy system maintenance, repair, and obsolescence mitigation. SST39VF1601C is the designated replacement, but SST39VF1602-70-4C-B3KE retains full datasheet compliance and long-term supply assurance through Aetrix Electronics.
What is the purpose of the Security ID feature in SST39VF1602-70-4C-B3KE?
The Security ID provides 256 bits of tamper-resistant identification: 128 bits factory-programmed by SST and 128 bits user-programmable. It enables secure firmware binding, device authentication, and anti-cloning - accessed via dedicated command sequence (88H) and locked after programming. This feature is detailed in DS25028A Section 10 and distinguishes SST39VF1602-70-4C-B3KE from generic parallel flash devices.
