Product details
Overview
SST39VF1601C-70-4I-EKE from Silicon Storage Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with bottom-boot block protection, 70 ns read access time, single 2.7–3.6 V supply operation, and JEDEC-standard x16 asynchronous interface. It delivers 100,000 program/erase cycles endurance and >100 years data retention for embedded firmware storage in industrial controllers.
For engineers reviewing the SST39VF1601C-70-4I-EKE datasheet, SST39VF1601C-70-4I-EKE pinout, SST39VF1601C-70-4I-EKE application, or SST39VF1601C-70-4I-EKE equivalent, this page provides verified pin functions, boot-block address mapping, erase-suspend capability, hardware write protection behavior, and real-world timing validation for system integration.
Technical Context
The SST39VF1601C-70-4I-EKE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of cycle count. Its architecture supports uniform 2 KWord sectors and flexible non-uniform blocks (one 8-, two 4-, one 16-, and thirty-one 32-KWord blocks).
It features latched address/data, CMOS I/O compatibility, and three end-of-write detection methods: Toggle Bit (DQ6/DQ2), Data# Polling (DQ7), and open-drain RY/BY# signal. Hardware block protection targets the bottom 8 KWord (00000H–01FFFH), activated when WP# is low.
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 bus systems. |
| Read Access Time | 70 ns maximum; enables direct execution from flash (XIP) at ≤14 MHz bus clock 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 firmware updates over 10+ years in industrial deployments. |
| Data Retention | Greater than 100 years at 25°C; ensures long-term reliability in unpowered storage applications. |
| Active Current | 9 mA typical at 5 MHz; enables low-power operation in battery-backed or energy-constrained edge devices. |
| Standby Current | 3 µA typical; reduces quiescent power in sleep-mode systems such as remote sensors or metering endpoints. |
| Erase Architecture | Uniform 2 KWord sectors + mixed-size blocks; allows selective firmware patching without full chip erase. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, standard pinout per JEDEC MO-142AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A0–A11 select sector during Sector-Erase; A0–A15 select block during Block-Erase. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# is high; latched on rising edge of WE# or CE#. |
| CE# | Chip Enable | Active-low device selection; must be low for read/write; high forces standby mode (3 µA current). |
| OE# | Output Enable | Active-low output gating; controls data bus drive; high places DQ lines in high-impedance state. |
| WE# | Write Enable | Active-low control for write operations; falling edge latches address; rising edge latches data/command. |
| WP# | Write Protect | Active-low hardware lock for bottom 8 KWord boot block (00000H–01FFFH); prevents accidental erase/program. |
| RST# | Hardware Reset | Active-low reset input; terminates ongoing erase/program and returns device to Read mode within TRP. |
| 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 supply; powers all internal logic and SuperFlash array; no VPP required. |
| VSS | Ground | Reference ground for all signals and internal circuitry; dual VSS pins ensure stable return path. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows reading or programming non-suspended sectors during active erase-critical for real-time firmware update handlers. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid read access; eliminates need for software-controlled standby entry. |
| Security ID Space | 128-bit factory-programmed ID + 128-word user-programmable space; supports secure boot key binding and device authentication. |
| Common Flash Interface (CFI) | JEDEC CFI Query mode (command 98H) provides runtime-readable geometry, timing, and command set metadata for portable bootloader support. |
| Software Data Protection | Three-byte unlock sequence required before any program; six-byte sequence before erase-prevents spurious writes during power transients. |
| Toggle Bit & Data# Polling | Dual-status detection (DQ6/DQ7) enables robust host polling without dedicated RY/BY# hardware dependency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160DBTI-70G | 16 Mbit x16, 70 ns, bottom-boot, but uses older floating-gate technology; 10,000-cycle endurance vs. 100,000. | Lacks Erase-Suspend and Auto Low Power Mode; requires longer 20 µs word-program time. | Choose only if legacy design reuse mandates identical pinout and command set without SuperFlash benefits. |
| S29AL016J70TFI020 | 16 Mbit x16, 70 ns, bottom-boot, 100,000-cycle endurance, but no hardware WP#-relies solely on software protection. | Missing dedicated WP# pin increases risk of inadvertent boot-block overwrite during brown-out conditions. | Select when CFI query support and toggle-bit detection are prioritized over hardware write lock assurance. |
Compared with MX29LV160DBTI-70G and S29AL016J70TFI020, the SST39VF1601C-70-4I-EKE uniquely combines bottom-boot hardware protection, fixed-timing SuperFlash, and auto-low-power mode-enabling safer, lower-power, and more predictable firmware storage in mission-critical embedded systems.

FAQ
What boot block configuration does SST39VF1601C-70-4I-EKE implement?
The SST39VF1601C-70-4I-EKE implements bottom-boot block protection, covering address range 00000H–01FFFH (8 KWords). This is hardwired into the silicon and differs from the top-boot SST39VF1602C. WP# must be held low to activate hardware lock on this region, preventing accidental erase or program during system operation.
Does SST39VF1601C-70-4I-EKE require an external VPP voltage for programming?
No, the SST39VF1601C-70-4I-EKE does not require external VPP. It generates internal high-voltage programming pulses using its on-chip charge pump, enabled by the 2.7–3.6 V VDD supply alone. This simplifies board design and eliminates need for dedicated VPP regulators or routing.
How is end-of-write detection implemented in SST39VF1601C-70-4I-EKE?
The SST39VF1601C-70-4I-EKE supports three independent end-of-write detection methods: Toggle Bit (DQ6 toggles during operation, stops when complete), Data# Polling (DQ7 complements during write, returns true data on completion), and Ready/Busy# (RY/BY# open-drain output pulled low during operation). All are usable concurrently.
Can SST39VF1601C-70-4I-EKE be used in systems requiring CFI compliance?
Yes, the SST39VF1601C-70-4I-EKE fully supports Common Flash Interface (CFI) per JEDEC JESD68. Entering CFI Query mode via command 98H at address 555H returns standardized geometry, timing, and command-set descriptors-enabling generic flash-aware bootloaders to auto-configure without hard-coded parameters.
What is the function of the RST# pin on SST39VF1601C-70-4I-EKE?
The RST# pin on SST39VF1601C-70-4I-EKE provides hardware-initiated reset to Read mode. When asserted low for ≥TRP (typ. 100 ns), it aborts any ongoing erase or program operation and forces immediate return to array read state. After release, TRHR (typ. 100 ns) delay is required before valid reads resume.
