Product details
Overview
SST39VF1602C-70-4I-B3KE-T from Silicon Storage Technology is a 16 Mbit (1M × 16) x16 asynchronous Multi-Purpose Flash Plus memory IC with top-boot block protection, 70 ns read access time, single 2.7–3.6 V supply operation, and JEDEC-standard pinout. It delivers fast Word-Program (7 µs typical), sector/block/chip erase (18/18/40 ms typical), and supports hardware write protection, erase-suspend/resume, and Security ID for embedded firmware storage in industrial control panels.
For engineers reviewing the SST39VF1602C-70-4I-B3KE-T datasheet, SST39VF1602C-70-4I-B3KE-T pinout, SST39VF1602C-70-4I-B3KE-T application, or SST39VF1602C-70-4I-B3KE-T equivalent, this page provides verified pin functions, boot-block address mapping (FE000H–FFFFFH), RY/BY# status signaling, WP#-enabled top-block protection, and CFI-compliant identification - all critical for legacy system upgrades and BOM continuity planning.
Technical Context
The SST39VF1602C-70-4I-B3KE-T implements SuperFlash split-gate technology for fixed erase/program timing independent of cycle count, enabling deterministic firmware update timing without software de-rating. Its architecture features uniform 2 KWord sectors and flexible non-uniform blocks (thirty-one 32 KWord, one 16 KWord, two 4 KWord, one 8 KWord), with top-boot block protection covering FE000H–FFFFFH.
It supports three end-of-write detection methods: Ready/Busy# (open-drain, requires external pull-up), Data# Polling (DQ7), and Toggle Bits (DQ6/DQ2), and includes hardware reset (RST#), latched address/data, and CFI query mode for automated system identification - all compliant with JEDEC standard pinouts and command sets for x16 flash memories.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16) - supports 2 MB of firmware or configuration data in x16 bus interface systems. |
| Read Access Time | 70 ns - enables direct connection to 14 MHz microcontrollers without wait states. |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V. |
| Word-Program Time | 7 µs typical - reduces firmware patch latency and improves field update throughput. |
| Erase Cycle Endurance | 100,000 cycles typical - supports >10 years of daily reprogramming in industrial logging applications. |
| Data Retention | Greater than 100 years - ensures long-term reliability for unattended infrastructure equipment. |

Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, suitable for high-density PCB layouts in space-constrained industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A19–A11 select block during erase, A11–A0 select sector or word. |
| DQ0–DQ15 | Data I/O | x16 bidirectional data bus; tri-stated when CE# or OE# is high; supports JEDEC-standard read/write protocols. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; high = high-impedance state. |
| WE# | Write Enable | Active-low write strobe; latches address/data on falling/rising edges per JEDEC timing; initiates command sequences. |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block; grounded = protection enabled (FE000H–FFFFFH). |
| RST# | Hardware Reset | Active-low asynchronous reset; terminates in-progress erase/program and forces return to read mode. |
| RY/BY# | Ready/Busy# | Open-drain status output; pulled low during erase/program; requires external 10–100 kΩ pull-up to VDD. |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; internal VPP generation eliminates need for external high-voltage pump. |
| VSS | Ground | Primary ground reference for all signals and internal circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Fixed 7 µs program and 18 ms erase times across full lifecycle - eliminates software timing margining and simplifies firmware update logic. |
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during erase - enables concurrent status monitoring and interrupt-driven system operation. |
| Security ID Space | 128-bit factory-programmed SST ID + 128-word user-programmable segment - supports secure device authentication and OEM branding. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid read - cuts power by >99% during idle polling in battery-backed systems. |
| JEDEC Pin & Command Compliance | Fully compatible with industry-standard x16 flash controllers and BIOS/UEFI firmware stacks - enables drop-in replacement in legacy designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4I-B3KE-T | Bottom-boot architecture (00000H–01FFFH protected); identical timing, voltage, and package. | Used where bootloader resides in lowest memory region instead of top; incompatible pin-level replacement due to different boot-block mapping. | Select only if existing design uses bottom-boot layout and WP# protection must cover lower 8 KWord. |
| MX29LV160DTTC-70G | Same density, 70 ns access, 2.7–3.6 V, but uses different command set and lacks Security ID; no CFI support. | Requires firmware driver modification; not suitable for systems relying on CFI auto-detection or secure ID binding. | Choose for cost-sensitive replacements where CFI and Security ID are unused; verify command sequence compatibility before integration. |
Compared with SST39VF1602C-70-4I-B3KE-T, SST39VF1601C-70-4I-B3KE-T offers identical performance but inverted boot-block location, while MX29LV160DTTC-70G sacrifices CFI and security features for broader distributor availability - making SST39VF1602C-70-4I-B3KE-T optimal for secure, standards-compliant industrial firmware storage.

FAQ
What is the boot block configuration of SST39VF1602C-70-4I-B3KE-T?
The SST39VF1602C-70-4I-B3KE-T implements top-boot block protection, covering the address range FE000H–FFFFFH (8 KWord). This is controlled by the WP# pin: when grounded, it prevents program and erase operations on that top block. The SST39VF1602C-70-4I-B3KE-T differs from the SST39VF1601C variant, which protects the bottom 8 KWord (00000H–01FFFH).
Does SST39VF1602C-70-4I-B3KE-T support CFI (Common Flash Interface)?
Yes, the SST39VF1602C-70-4I-B3KE-T fully supports CFI via a standardized three-byte entry sequence (555H/AAH → 2AAH/55H → 555H/98H) or one-byte alternative (55H/98H). Once entered, CFI data at addresses 10H–35H provides geometry, timing, and command-set information - enabling automatic system identification and driver compatibility without hardcoded assumptions.
How does the Auto Low Power Mode function in SST39VF1602C-70-4I-B3KE-T?
The SST39VF1602C-70-4I-B3KE-T automatically enters Auto Low Power Mode after a valid read operation, reducing active current from 9 mA to 3 µA. It exits instantly on any address or control signal transition (e.g., CE# toggle) with no access time penalty. This mode is disabled at power-up until the first address transition occurs - ensuring predictable startup behavior in SST39VF1602C-70-4I-B3KE-T-based systems.
What are the valid methods to detect completion of a Program or Erase operation in SST39VF1602C-70-4I-B3KE-T?
The SST39VF1602C-70-4I-B3KE-T provides three hardware-supported detection methods: Ready/Busy# (open-drain RY/BY# pin), Data# Polling (DQ7 toggles/complements), and Toggle Bits (DQ6 and DQ2). All are valid after defined WE#/CE# edge counts per operation type - e.g., DQ6 toggling begins after the sixth WE# pulse in sector-erase - enabling robust, interrupt-driven firmware update logic in SST39VF1602C-70-4I-B3KE-T implementations.
Is SST39VF1602C-70-4I-B3KE-T compatible with standard x16 flash controllers?
Yes, the SST39VF1602C-70-4I-B3KE-T conforms fully to JEDEC standard pinouts and command sets for x16 flash memories. Its address/data/control signal mapping, timing parameters (70 ns read, 7 µs program), and protocol behavior (e.g., latching on WE#/CE# edges) match industry expectations - allowing direct integration with FPGA-based controllers, ASIC boot interfaces, and legacy microprocessor buses without adapter logic.
