Product details
Overview
SST39VF1602-70-4I-EKE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with JEDEC-standard x16 asynchronous interface, 70 ns read access time, hardware top-block protection, and SuperFlash technology enabling 100,000 program/erase cycles - deployed in embedded boot code storage for industrial controllers and legacy communication modules.
For engineers reviewing the SST39VF1602-70-4I-EKE datasheet, SST39VF1602-70-4I-EKE pinout, SST39VF1602-70-4I-EKE application, or SST39VF1602-70-4I-EKE equivalent, key selection considerations include top-boot block address range (0F8000H–0FFFFFH), TSOP-48 package compatibility, 2.7–3.6V single-supply operation, and Erase-Suspend capability for real-time firmware updates.
Technical Context
The SST39VF1602-70-4I-EKE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, delivering fixed erase/program times independent of cycle count. It supports standard JEDEC command sets including Word-Program (7 µs typical), Sector-Erase (18 ms), Block-Erase (18 ms), and Chip-Erase (40 ms).
Its control logic integrates hardware reset (RST#), write protect (WP#) for top 32 KWord boot block, and dual status detection via DQ7 (Data# Polling) and DQ6/DQ2 (Toggle Bits). The device enters Auto Low Power mode after valid read, reducing active current from 9 mA to 3 µA without access penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization), providing 2 MB of nonvolatile storage space |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in 5 MHz bus systems 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 |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over 10+ years in industrial deployments |
| Data Retention | Greater than 100 years - ensures long-term reliability in unpowered storage applications |

| Erase Architecture | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (256 KB) - enables granular firmware partitioning |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for full 1M×16 addressing; A19 selects top boot block (0F8000H–0FFFFFH) during protection enable |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with latched inputs and tri-state outputs controlled by CE# and OE# |
| 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 visibility during read; high disables outputs |
| WE# | Write Enable | Active-low write strobe - latches address/data on falling/rising edges per JEDEC command timing |
| WP# | Write Protect | Active-low hardware lock for top 32 KWord boot block - grounded to prevent erase/program of bootloader region |
| RST# | Reset | Active-low hardware reset - forces return to read mode and aborts in-progress erase/program |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling required within 10 mm of VDD pin per JEDEC layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend / Resume | Allows real-time read access to non-suspended sectors during background erase - critical for fail-safe firmware update sequences |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts power in intermittently polled control registers |
| Security ID Space | 256-bit factory + user programmable ID (128 + 128 bits) - enables secure device authentication and firmware binding |
| Common Flash Interface (CFI) | JEDEC CFI Query mode accessible at 5555H/98H - enables runtime detection of geometry, timing, and command set |
| Software Data Protection | Three-byte unlock sequence required before programming; six-byte sequence before erase - prevents spurious writes during power transients |

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-EKE | Bottom-boot configuration (000000H–007FFFH protected); same density, timing, and package | Used where bootloader resides in lowest memory region instead of top - requires PCB address wiring change | Select only if bottom-block protection aligns with system memory map and bootloader location |
| MX29LV160DTTI-70G | 16 Mbit x16, 70 ns, but uses different command set (no Erase-Suspend) and lacks CFI support | Requires firmware driver rewrite; no runtime geometry detection; lower endurance (10,000 cycles) | Consider only for cost-sensitive replacements where suspend/resume and CFI are unused |
Compared with SST39VF1602-70-4I-EKE, the SST39VF1601C offers identical performance but inverted boot-block orientation, while MX29LV160DTTI-70G sacrifices suspend capability and endurance for broader distributor availability - neither is pin-compatible nor drop-in.

FAQ
What does the "-4I-EKE" suffix indicate in SST39VF1602-70-4I-EKE?
The "-4I-EKE" suffix specifies industrial temperature grade (-40°C to +85°C), 48-pin TSOP package (EKE), and lead-free/RoHS-compliant construction. The "-70" denotes 70 ns maximum read access time. This exact variant is qualified for extended thermal cycling and humidity exposure per JEDEC JESD22-A108.
Is SST39VF1602-70-4I-EKE pin-compatible with SST39VF1601 variants?
No - SST39VF1602-70-4I-EKE implements top-boot block protection (0F8000H–0FFFFFH), while SST39VF1601 uses bottom-boot (000000H–007FFFH). Though both share identical TSOP-48 pinout and electrical interface, address decoding for WP#-protected regions differs, requiring firmware and memory map adjustments.
Does SST39VF1602-70-4I-EKE support Common Flash Interface (CFI)?
Yes - SST39VF1602-70-4I-EKE fully supports JEDEC CFI Query mode. Executing the three-byte command sequence (5555H/AAH → 2AAAH/55H → 5555H/98H) enables reading standardized geometry, timing, and command-set descriptors from predefined CFI address offsets (e.g., 10H–12H for "QRY" string).
How is hardware write protection implemented on SST39VF1602-70-4I-EKE?
Hardware write protection is activated by grounding the WP# pin, which locks the top 32 KWord (256 KB) boot block (0F8000H–0FFFFFH) against all program and erase commands. When WP# is left floating, an internal pull-up holds it high, disabling protection. This mechanism operates independently of software data protection.
What is the minimum VDD required for reliable operation of SST39VF1602-70-4I-EKE?
SST39VF1602-70-4I-EKE requires VDD ≥ 2.7 V for all operations including read, program, and erase. Below 2.7 V, internal voltage detectors inhibit write cycles, and read access may return invalid data. The device remains in reset state until VDD stabilizes above 2.7 V for ≥ 100 µs after power-on.
