Product details
Overview
SST39VF1601-70-4C-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, single 2.7–3.6V supply operation, and bottom 32 KWord hardware block protection. It is used for firmware storage, BIOS code, and configuration data in embedded controllers and industrial HMI systems.
For engineers reviewing the SST39VF1601-70-4C-EKE datasheet, SST39VF1601-70-4C-EKE pinout, SST39VF1601-70-4C-EKE application, or SST39VF1601-70-4C-EKE equivalent, key selection criteria include boot-block protection scheme, TSOP-48 package compatibility, 70 ns timing compliance, SuperFlash endurance (100,000 cycles), and CFI query support for system-level identification.
Technical Context
The SST39VF1601-70-4C-EKE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It supports Word-Program (7 µs typical), Sector-Erase (18 ms), Block-Erase (18 ms), and Chip-Erase (40 ms), all with internal VPP generation and no external high-voltage requirement.
Operation relies on standard JEDEC command sets with software data protection (three-byte unlock sequence for program, six-byte for erase), plus hardware write protection via WP# tied low to protect the bottom 32 KWord boot block (000000H–007FFFH). Status detection uses DQ7 Data# Polling and DQ6/DQ2 Toggle Bits, with Erase-Suspend/Erase-Resume capability for real-time read during background erase.
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 - meets timing requirements for 14 MHz bus interfaces without wait states |
| Supply Voltage | 2.7–3.6V - enables direct integration into 3.3V logic systems without level-shifting |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over product lifetime |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Block Protection | Bottom 32 KWord (000000H–007FFFH) protected when WP# = low - safeguards boot code against corruption |
| Package | 48-lead TSOP (12 mm × 20 mm) - industry-standard footprint compatible with legacy PCB layouts |
Pinout & Package
48-lead Thin Small Outline Package (TSOP-I, 12 mm × 20 mm, JEDEC MO-142AC), lead-free and RoHS compliant. Pin 1 marked by notch or dot; top view, die-up orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for full 1M × 16 addressing; A19 is MSB and required for sector/block selection during erase |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during write; tri-stated when CE# or OE# high |
| 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; high disables outputs regardless of CE# state |
| WE# | Write Enable | Active-low control for write cycles - latches address/data edges; initiates internal program/erase timing |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block - prevents accidental erase/program when grounded |
| RST# | Reset | Active-low hardware reset - forces return to Read mode within TRP (100 ns min); required after power-up instability |
| VDD | Power Supply | 2.7–3.6V core supply - powers all logic and memory array; no separate VPP required |
| VSS | Ground | Reference ground for all signals and internal circuitry; two dedicated pins (pins 23 and 47) |
| NC | No Connect | Pins 3, 12, 15, 24, 32, 43 - electrically isolated; must be left floating or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell architecture delivers fixed 7 µs program and 18 ms erase times across full lifecycle - eliminates software de-rating |
| Erase-Suspend Capability | Allows real-time read from non-suspended sectors during active erase - enables responsive UI updates in HMI systems |
| CFI Query Support | Standard Common Flash Interface (CFI) at address 5555H enables automatic driver detection and configuration in bootloader environments |
| Security ID Space | 256-bit factory + user-programmable ID (128 + 128 bits) - supports secure device authentication and firmware binding |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts dynamic power in intermittently polled systems |
Applications

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 16 Mbit density and TSOP-48 package, but rated for 55 ns access time and extended temperature range (–40°C to +105°C) | Required for automotive under-hood or industrial high-temp deployments where 70 ns timing margin is insufficient | Select SST39VF1601C when ambient operating temperature exceeds +85°C or sub-55 ns read latency is mandatory |
| MX29LV160ETTI-70G | 16 Mbit x16 flash from Macronix; 70 ns access, same TSOP-48 footprint, but uses different command set and lacks CFI query support | Suitable for cost-sensitive consumer electronics where bootloader flexibility is not required and firmware is vendor-locked | Choose MX29LV160ETTI-70G only if existing design already uses Macronix-compatible drivers and no CFI auto-detection is needed |
Compared with SST39VF1601C, the SST39VF1601-70-4C-EKE offers lower cost and adequate timing for commercial-temperature applications, while MX29LV160ETTI-70G trades CFI interoperability for broader second-source availability in non-CFI-aware systems.

FAQ
What does the "-70" suffix indicate in SST39VF1601-70-4C-EKE?
The "-70" denotes 70 ns maximum read access time at VDD = 2.7–3.6V and TA = 0°C to +70°C. This timing grade ensures compatibility with 14 MHz system buses without wait-state insertion. The SST39VF1601-70-4C-EKE achieves this performance using SST's SuperFlash technology, which maintains consistent access latency across its full operational lifetime and temperature range.
Is SST39VF1601-70-4C-EKE pin-compatible with SST39VF1602 variants?
No - SST39VF1601-70-4C-EKE and SST39VF1602 differ in hardware block protection mapping: SST39VF1601-70-4C-EKE protects the bottom 32 KWord (000000H–007FFFH), while SST39VF1602 protects the top 32 KWord (0F8000H–0FFFFFH). Though both use identical TSOP-48 pinouts and command sets, swapping them requires firmware revision to align with the protected address range.
Does SST39VF1601-70-4C-EKE support Common Flash Interface (CFI)?
Yes - SST39VF1601-70-4C-EKE implements full CFI Query mode per JEDEC JESD68. By issuing the three-byte command sequence (5555H/AAH → 2AAAH/55H → 5555H/98H), the host can read standardized geometry, timing, and command-set descriptors from fixed CFI address locations (e.g., 10H–12H for "QRY" string), enabling automatic driver initialization in Linux MTD or U-Boot environments.
How is hardware write protection implemented on SST39VF1601-70-4C-EKE?
Hardware write protection on SST39VF1601-70-4C-EKE is controlled by the WP# pin: when pulled low, it permanently disables Program and Erase operations on the bottom 32 KWord boot block (000000H–007FFFH). The pin has an internal pull-up resistor, so leaving WP# unconnected defaults to unprotected mode. This feature ensures bootloader integrity even during brown-out or glitch conditions that might corrupt software protection flags.
What is the purpose of the RST# pin on SST39VF1601-70-4C-EKE?
The RST# pin provides hardware-level recovery: asserting RST# low for ≥100 ns forces immediate termination of any ongoing Program or Erase operation and returns the SST39VF1601-70-4C-EKE to Read mode. After release, a minimum hold time (TRHR) is required before valid reads resume. This is critical for power-fail recovery and watchdog-triggered system resets where software-initiated abort sequences may be unreliable.
