Product details
Overview
SST39VF1602C-70-4C-EKE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with 70 ns read access time, 2.7–3.6 V single-supply operation, and top-boot hardware block protection. It delivers 100,000 program/erase cycles endurance and >100 years data retention, targeting embedded firmware storage in industrial controllers and legacy system BIOS modules.
For engineers reviewing the SST39VF1602C-70-4C-EKE datasheet, SST39VF1602C-70-4C-EKE pinout, SST39VF1602C-70-4C-EKE application, or SST39VF1602C-70-4C-EKE equivalent, this page provides verified JEDEC-compliant x16 flash specifications, TSOP-48 pin mapping, boot-block protection behavior, erase-suspend capability, and direct alternatives for legacy design refresh or supply continuity.
Technical Context
The SST39VF1602C-70-4C-EKE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, 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 block sizes (eight 32 KWord, one 16 KWord, two 4 KWord, and one 8 KWord blocks), with top-boot protection covering FE000H–FFFFFH (8 KWord).
It features three write-status detection methods-Data# Polling (DQ7), Toggle Bits (DQ6/DQ2), and open-drain RY/BY#-and integrates hardware reset (RST#), write protect (WP#), and security ID (128-bit factory + 128-word user space). All operations comply with JEDEC-standard x16 flash command sets and pinouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, JEDEC-standard x16 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) plus 4 extended address lines (A16–A19); AMS = A19 for sector/block selection |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with internal latching; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low device select; must be low to enable read/write operations |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read cycles only |
| WE# | Write Enable | Active-low control for all write operations (program/erase); latches address/data on edge transitions |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block (FE000H–FFFFFH); floating = unprotected |
| RST# | Hardware Reset | Active-low signal forcing immediate return to read mode; terminates in-progress erase/program |
| RY/BY# | Ready/Busy# | Open-drain status indicator; pulled low during erase/program, requires external 10–100 kΩ pull-up |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; no separate VCCIO required |
| VSS | Ground | Primary ground reference for all signals and internal circuitry |
| NC | No Connection | Unbonded pins (e.g., pins 2, 46, 47 in TSOP); must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Erase-Resume | Allows temporary interruption of sector/block erase to read or program other locations - critical for real-time firmware update without system freeze |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - eliminates need for external power gating in battery-backed systems |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user-programmable space - enables secure device authentication and version tracking |
| JEDEC Standard Compliance | Fully compatible with industry-standard x16 flash command sets and pinouts - ensures drop-in replacement across multiple vendors |
| SuperFlash Fixed Timing | 7 µs word-program and 18 ms erase times remain constant over full endurance life - removes software de-rating and simplifies timing margin analysis |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4C-EKE | Bottom-boot architecture (00000H–01FFFH protected); identical timing, voltage, and package | Used where bootloader resides at lowest address; incompatible pin-for-pin due to different boot-block mapping | Select only if bottom-boot protection aligns with system memory map and bootloader location |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V; supports CFI but lacks Security ID and erase-suspend | Lower-cost alternative for non-security-critical applications; requires software workaround for suspend/resume | Choose when Security ID and real-time erase suspension are not required and CFI query support is preferred |
Compared with SST39VF1602C-70-4C-EKE, the SST39VF1601C offers mirrored boot-block protection but no functional overlap in address layout, while MX29LV160ETTI-70G sacrifices security and suspend features for cost reduction - making SST39VF1602C-70-4C-EKE optimal for safety-critical or field-upgradable systems requiring deterministic boot integrity.

FAQ
What is the boot-block protection scheme of the SST39VF1602C-70-4C-EKE?
The SST39VF1602C-70-4C-EKE implements top-boot hardware block protection covering address range FE000H–FFFFFH (8 KWord). When WP# is grounded, program and erase operations are inhibited in this region. This ensures bootloader integrity during field firmware updates. The SST39VF1602C-70-4C-EKE differs from SST39VF1601C, which protects the bottom 8 KWord block instead.
Does the SST39VF1602C-70-4C-EKE support erase-suspend functionality?
Yes, the SST39VF1602C-70-4C-EKE supports Erase-Suspend and Erase-Resume commands (B0H and 30H). This allows interruption of an ongoing sector or block erase to read data or program other unprotected regions. The SST39VF1602C-70-4C-EKE exits suspend mode within 20 µs and resumes erase upon receipt of the Resume command - essential for real-time embedded systems.
What are the valid packages for SST39VF1602C-70-4C-EKE?
The SST39VF1602C-70-4C-EKE is offered in three RoHS-compliant packages: 48-lead TSOP (12 mm × 20 mm), 48-ball TFBGA (6 mm × 8 mm), and 48-ball WFBGA (4 mm × 6 mm). The "-EKE" suffix specifically denotes the 48-lead TSOP variant. Pin assignments differ across packages, so PCB layout must match the selected variant - the SST39VF1602C-70-4C-EKE uses the standard JEDEC x16 TSOP pinout.
How does the SST39VF1602C-70-4C-EKE indicate completion of a program or erase operation?
The SST39VF1602C-70-4C-EKE provides three concurrent status mechanisms: Data# Polling (DQ7 toggles until completion), Toggle Bits (DQ6 toggles during operation), and Ready/Busy# (RY/BY# open-drain output pulled low during active write). All are valid after the rising edge of the final WE# pulse. The SST39VF1602C-70-4C-EKE requires no external polling delay - status is deterministic and cycle-accurate.
Is the SST39VF1602C-70-4C-EKE compatible with JEDEC-standard x16 flash interfaces?
Yes, the SST39VF1602C-70-4C-EKE fully complies with JEDEC Standard JESD21-C for x16 flash memories, including pinout, command set (e.g., 555H/2AAH unlock sequences), and timing definitions. It supports CFI Query mode (98H command) for automatic identification. This ensures interoperability with existing x16 flash controllers and eliminates protocol translation in legacy designs using SST39VF1602C-70-4C-EKE.
