Product details
Overview
SST39VF1601-70-4C-EKE-T 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 bottom 32 KWord hardware block protection. It supports sector/block/chip erase, word-program (7 µs typical), and erase-suspend/resume - deployed in embedded boot code storage for industrial controllers and legacy communication modules.
For engineers reviewing the SST39VF1601-70-4C-EKE-T datasheet, SST39VF1601-70-4C-EKE-T pinout, SST39VF1601-70-4C-EKE-T application, or SST39VF1601-70-4C-EKE-T equivalent, key selection criteria include JEDEC x16 pin compatibility, 48-lead TSOP package footprint, bottom-boot block protection mapping, and SuperFlash endurance (100,000 cycles) for firmware update reliability in space-constrained designs.
Technical Context
The SST39VF1601-70-4C-EKE-T implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command interface follows JEDEC-standard x16 flash protocols, including six-byte erase sequences and three-byte program initiation.
It features dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits), hardware WP#-controlled bottom-block protection (000000H–007FFFH), and RST#-driven hardware reset to recover from incomplete operations - all operating within strict 2.7–3.6 V VDD compliance without external VPP.
Key Specifications

Pinout & Package
48-lead TSOP (Thin Small Outline Package), standard JEDEC x16 flash pinout, 12 mm × 20 mm body, die-up orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for 1M×16 addressing; A19 is MSB for SST39VF1601 (not connected in this variant per Figure 2) |
| DQ0–DQ15 | Data I/O | Bi-directional x16 data bus; latched internally during write; tri-state when CE# or OE# high |

| OE# | Output Enable | Active-low output gate; high impedance when deasserted; used for read data gating |
| WE# | Write Enable | Active-low control for write cycles; falling edge latches address, rising edge latches data |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH) |
| RST# | Reset | Active-low hardware abort of in-progress erase/program; forces return to read mode |
| VDD | Power Supply | 2.7–3.6 V core supply; powers internal charge pump for erase/program |
| VSS | Ground | Reference for all I/O and internal logic; two dedicated pins for noise reduction |
| NC | No Connect | Pins 3, 12, 15, 26, 42 - unconnected; must be left floating or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access during erase - critical for interrupt-driven boot loaders needing status polling |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts standby power in always-on systems |
| Security ID | 256-bit factory + user programmable ID space - enables secure firmware binding and anti-cloning in OEM devices |
| CFI Support | JEDEC Common Flash Interface compliant - enables OS-level auto-detection and generic flash drivers |
| SuperFlash Reliability | Fixed 18 ms sector/block erase time regardless of wear - eliminates software de-rating and timing margin creep |
Applications
| Industrial PLC Firmware Storage | Legacy Telecom Baseband Boot Memory |
|---|---|
Use Scenario: Storing boot code and configuration parameters in DIN-rail mounted programmable logic controllers exposed to wide temperature swings and EMI. IC Role / Device Role / Timing Role: Nonvolatile boot ROM with hardware-protected bottom block ensuring bootloader integrity during field firmware upgrades. Use Value: Bottom-block protection prevents corruption during power-loss events; 100-year retention guarantees firmware persistence across 15+ year product lifecycles. |
Use Scenario: Holding DSP initialization code and calibration tables in discontinued GSM base station transceivers requiring long-term component availability. IC Role / Device Role / Timing Role: x16 asynchronous flash memory interfaced directly to TI C54x DSP EMIF with 70 ns access matching bus timing budgets. Use Value: 70 ns read speed meets tight DSP boot timing; TSOP package fits legacy 0.5 mm pitch layouts without redesign. |
| Medical Diagnostic Equipment BIOS | Automotive Body Control Module (BCM) Calibration Storage |
Use Scenario: Storing safety-critical startup routines and self-test sequences in portable ultrasound imaging units subject to rigorous IEC 62304 validation. IC Role / Device Role / Timing Role: Secure, tamper-resistant firmware store with programmable Security ID for traceability and version control. Use Value: Factory-programmed 128-bit ID enables audit trail generation; 100,000-cycle endurance supports regulatory-required field update logs. |
Use Scenario: Retaining vehicle-specific calibration data (e.g., window lift profiles, mirror positions) across battery disconnects in Tier-1 BCMs. IC Role / Device Role / Timing Role: Low-power, high-reliability nonvolatile memory with Auto Low Power mode reducing quiescent current to 3 µA. Use Value: 3 µA standby current extends battery backup life beyond 10 years; bottom-block protection isolates calibration data from main firmware updates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Same density and pinout; improved 55 ns access time; RoHS-compliant revision per Microchip notice | Preferred for new designs requiring faster boot times or updated environmental compliance | Select SST39VF1601C if board layout allows same 48-TSOP footprint and system timing budget permits tighter 55 ns access. |
| MX29LV160DTTC-70G | 16 Mbit x16, 70 ns, but uses different command set (Spansion protocol); no erase-suspend; no Security ID | Lacks suspend/resume and security features; requires firmware driver changes | Consider only if existing Spansion-based firmware stack is reused and bottom-block protection suffices without advanced features. |
Compared with SST39VF1601C, the SST39VF1601-70-4C-EKE-T offers identical functionality but slower access and older qualification; versus MX29LV160DTTC-70G, it delivers unique SuperFlash reliability and security extensions at the cost of vendor-specific command compatibility.

FAQ
What does the "-70" suffix indicate in SST39VF1601-70-4C-EKE-T?
The "-70" denotes 70 ns maximum read access time - a critical timing parameter defining the shortest interval between address assertion and valid data on DQ0–DQ15. This value is guaranteed across the full industrial temperature range (-40°C to +85°C) and 2.7–3.6 V supply, directly impacting boot latency in microcontroller-based systems using the SST39VF1601-70-4C-EKE-T as primary firmware storage.
Is SST39VF1601-70-4C-EKE-T pin-compatible with SST39VF1602 variants?
No - SST39VF1601-70-4C-EKE-T implements bottom 32 KWord block protection (000000H–007FFFH), while SST39VF1602 uses top-block protection (0F8000H–0FFFFH). Though both share identical 48-TSOP pinouts and command sets, the WP# protection region differs, requiring firmware and memory map adjustments when substituting. The SST39VF1601-70-4C-EKE-T must be used where boot code resides in the lower address space.
Does SST39VF1601-70-4C-EKE-T require an external VPP voltage for programming?
No - the SST39VF1601-70-4C-EKE-T integrates an internal charge pump that generates all required high-voltage programming signals from the single 2.7–3.6 V VDD supply. This eliminates external VPP circuitry, simplifies PCB design, and reduces BOM cost - a key advantage of SST's SuperFlash architecture implemented in the SST39VF1601-70-4C-EKE-T.
How is hardware block protection enabled on SST39VF1601-70-4C-EKE-T?
Hardware block protection on the SST39VF1601-70-4C-EKE-T is activated by pulling the WP# pin low, which locks the bottom 32 KWord (000000H–007FFFH) from program/erase operations. When WP# is left floating, an internal pull-up holds it high, disabling protection. This mechanism operates independently of software commands and remains active during power transitions - ensuring bootloader safety in the SST39VF1601-70-4C-EKE-T even during brown-out conditions.
What JEDEC standards does SST39VF1601-70-4C-EKE-T comply with?
The SST39VF1601-70-4C-EKE-T conforms to JEDEC Standard JESD21-C for x16 flash pinouts and JESD22-A117 for endurance testing (100,000 cycles), and implements the Common Flash Interface (CFI) per JEDEC JESD68. Its command set aligns with JEDEC JEP137-B for software data protection, enabling interoperability with standard flash file systems and bootloader frameworks that rely on these specifications for the SST39VF1601-70-4C-EKE-T.
