Product details
Overview
SST39VF1602C-70-4C-B3KE from Silicon Storage Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with top-boot block protection, 70 ns read access time, 2.7–3.6 V single-supply operation, and JEDEC-standard x16 asynchronous interface. It delivers fast Word-Program (7 µs typical), sector/block/chip erase, and hardware write protection for embedded firmware storage in industrial controllers and legacy system BIOS.
For engineers reviewing the SST39VF1602C-70-4C-B3KE datasheet, SST39VF1602C-70-4C-B3KE pinout, SST39VF1602C-70-4C-B3KE application, or SST39VF1602C-70-4C-B3KE equivalent, this page provides verified pin functions, boot-block architecture details, endurance (100,000 cycles), data retention (>100 years), and real-world flash management features including Erase-Suspend/Resume and Security ID support.
Technical Context
The SST39VF1602C-70-4C-B3KE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed erase/program timing independent of cycle count. Its top-boot architecture protects the FE000H–FFFFFH region (8 KWord) via WP# pin grounding.
It supports three software status detection methods-Data# Polling (DQ7), Toggle Bits (DQ6/DQ2), and Ready/Busy# (open-drain RY/BY#)-and integrates CFI query mode for automatic device identification. Command execution follows JEDEC-standard six-byte sequences for sector/block/chip erase and three-byte sequences for word-program.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words); supports firmware image storage up to 2 MB in x16 configuration. |
| Read Access Time | 70 ns maximum; enables direct execution from flash (XIP) in 5 MHz microcontroller systems without wait states. |
| Supply Voltage | 2.7–3.6 V single supply; compatible with 3.3 V logic rails and eliminates need for separate VPP programming voltage. |
| Endurance | 100,000 program/erase cycles typical; sufficient for field-upgradable firmware with infrequent updates over 10+ year product life. |
| Data Retention | Greater than 100 years at 25°C; ensures long-term reliability in unpowered storage applications like medical device calibration tables. |
| Erase Architecture | Uniform 2 KWord sectors + flexible blocks (thirty-one 32 KWord, one 16 KWord, two 4 KWord, one 8 KWord); allows granular firmware patching without full chip erase. |
| Top Boot Protection | Hardware-protected 8 KWord region (FE000H–FFFFFH); prevents accidental overwrite of boot code during field updates. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, bottom-side thermal pad optional per manufacturer recommendation.
| 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 during program/read. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; latched on WE#/CE# edges during write. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high; required low for all operations except reset. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; must be low with CE# low for valid read data. |
| WE# | Write Enable | Active-low write control; latches address/data on falling/rising edge per JEDEC command timing. |
| WP# | Write Protect | Active-low top-boot lock; grounds to protect FE000H–FFFFFH; internally pulled high if floating. |
| RST# | Hardware Reset | Active-low hard reset; terminates ongoing erase/program and forces return to read mode within TRP (max 100 ns). |
| RY/BY# | Ready/Busy# | Open-drain status indicator; pulled low during erase/program; requires external 10–100 kΩ pull-up to VDD. |
| VDD | Power Supply | 2.7–3.6 V core supply; powers internal charge pump for erase/program; no external VPP needed. |
| VSS | Ground | Primary ground reference; two dedicated VSS pins (pins 25, 48) reduce noise coupling in high-speed reads. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows read access to non-suspended sectors during active erase; critical for real-time systems requiring concurrent firmware validation and update. |
| Security ID Space | 128-bit factory-programmed SST ID + 128-word user-programmable space; enables secure device authentication and OEM feature locking. |
| 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. |
| Hardware Block Protection | Dedicated top-boot protection (SST39VF1602C only); eliminates need for software-based write-protection schemes vulnerable to crash-induced corruption. |
| CFI Query Support | JEDEC-standard Common Flash Interface; enables automatic driver detection and configuration in Linux/RTOS bootloaders without hardcoded parameters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, top-boot, but uses 3.0–3.6 V supply only; lacks Erase-Suspend and Security ID. | Compatible for basic BIOS storage but unsuitable for real-time suspend/resume or secure authentication use cases. | Select when cost sensitivity outweighs advanced flash management features and extended voltage range is not required. |
| EN29LV160AT-70TP | 16 Mbit x16, 70 ns, top-boot, 2.7–3.6 V, but endurance rated at 10,000 cycles (not 100,000); no CFI support. | Acceptable for low-update-frequency applications but fails long-life requirements in field-deployed industrial equipment. | Select only for short-lifecycle consumer products where firmware rarely changes and 10-year retention is sufficient. |
Compared with MX29LV160ETTI-70G and EN29LV160AT-70TP, the SST39VF1602C-70-4C-B3KE offers superior endurance (10× higher), integrated Erase-Suspend for real-time systems, and CFI/Security ID for automated driver integration and device authentication-making it the only choice for mission-critical, long-lifecycle embedded designs.

FAQ
What is the boot block configuration of the SST39VF1602C-70-4C-B3KE?
The SST39VF1602C-70-4C-B3KE implements top-boot block protection, securing the address range FE000H–FFFFFH (8 KWord) against accidental program/erase when WP# is grounded. This differs from the SST39VF1601C, which protects the bottom 8 KWord. The boot block location is fixed and cannot be reconfigured in the SST39VF1602C-70-4C-B3KE.
Does the SST39VF1602C-70-4C-B3KE require an external VPP voltage for programming?
No, the SST39VF1602C-70-4C-B3KE does not require an external VPP voltage. It generates internal high-voltage programming pulses using its on-chip charge pump, operating solely from the 2.7–3.6 V VDD supply. This eliminates external VPP circuitry and simplifies board design compared to older parallel flash devices.
How does Erase-Suspend functionality work in the SST39VF1602C-70-4C-B3KE?
The SST39VF1602C-70-4C-B3KE supports Erase-Suspend via the B0H command, allowing the host to temporarily halt an ongoing sector or block erase and read data from unprotected regions. During suspend, DQ2 toggles for suspended sectors while DQ6 = '1'; resume uses the 30H command. This enables real-time validation during firmware updates without interrupting erase progress.
What are the valid status detection methods for program/erase completion in the SST39VF1602C-70-4C-B3KE?
The SST39VF1602C-70-4C-B3KE provides three concurrent status detection methods: Data# Polling (DQ7 toggles until completion), Toggle Bits (DQ6 toggles during operation, stops when done), and Ready/Busy# (RY/BY# open-drain pin pulled low during operation). All are valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse.
Is the SST39VF1602C-70-4C-B3KE compatible with JEDEC-standard command sets?
Yes, the SST39VF1602C-70-4C-B3KE fully conforms to JEDEC standard pinouts and command sets for x16 flash memories, including Software Data Protection (SDP) sequences, CFI Query entry (98H), and Product Identification (90H). This ensures interoperability with standard flash drivers and programming tools without vendor-specific extensions.
