Product details
Overview
SST39VF1601C-70-4C-EKE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with JEDEC-standard x16 interface, 70 ns read access time, and single 2.7–3.6V supply operation. It features bottom-boot block protection (00000H–01FFFH), 100,000-cycle endurance, and >100-year data retention - deployed in embedded firmware storage for industrial controllers and legacy BIOS modules.
For engineers reviewing the SST39VF1601C-70-4C-EKE datasheet, SST39VF1601C-70-4C-EKE pinout, SST39VF1601C-70-4C-EKE application, or SST39VF1601C-70-4C-EKE equivalent, this page delivers verified pin functions, boot-block architecture details, sector/block/erase timing values, hardware reset (RST#) behavior, and JEDEC-compliant command-set compatibility - all confirmed against Microchip DS20005018B.
Technical Context
The SST39VF1601C-70-4C-EKE implements SST's SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its architecture supports uniform 2 KWord sectors and flexible blocks (one 8-, two 4-, one 16-, and thirty-one 32-KWord blocks), with hardware WP#-controlled bottom-boot protection.
It uses CMOS I/O compatible with JEDEC x16 flash standards, supports Auto Low Power mode (3 µA standby), and provides three end-of-write detection methods: Data# Polling (DQ7), Toggle Bits (DQ6/DQ2), and open-drain RY/BY# with external pull-up. Command execution requires strict six-byte sequences for erase operations and three-byte sequences for program/ID entry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization), supporting 2 MB addressable space |
| Read Access Time | 70 ns - determines minimum bus cycle time in 16-bit parallel interfaces |
| Supply Voltage | 2.7–3.6 V - enables direct integration with 3.3V logic systems without level shifting |
| Endurance | 100,000 program/erase cycles - defines field-revision limit for firmware update partitions |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Word-Program Time | 7 µs typical - sets worst-case latency for single-word configuration updates |
| Erase Times | Sector/Block: 18 ms typical; Chip: 40 ms typical - impacts full-image reflash duration |
| Boot Block Protection | Bottom 8 KWord (00000H–01FFFH) - safeguards bootloader code from accidental overwrite |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS compliant. Pin assignments conform to JEDEC standard x16 flash footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 extended address bits (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 chip select - device enters standby (3 µA) when high |
| OE# | Output Enable | Active-low output gate - controls data bus visibility during read cycles |
| WE# | Write Enable | Active-low control for write command latching; falling edge captures address, rising edge captures data |
| WP# | Write Protect | Active-low hardware lock for bottom boot block (00000H–01FFFH); floating = internally pulled high |
| RST# | Hardware Reset | Active-low asynchronous reset - forces return to read mode, aborting in-progress erase/program |
| RY/BY# | Ready/Busy# | Open-drain status indicator - low during erase/program; requires 10–100 kΩ pull-up to VDD |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply - no separate VCCIO required |
| VSS | Ground | Primary 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/Resume | Allows temporary read access during active sector/block erase - critical for real-time firmware patching |
| Security ID Space | 128-bit factory-programmed SST ID + 128-word user-programmable segment - enables secure device authentication |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid read - cuts power in burst-access embedded hosts |
| JEDEC CFI Support | Standardized query interface (entry via 98H at 555H) - enables OS/driver auto-detection of geometry and timing |
| Toggle Bit & Data# Polling | Dual software status detection (DQ6/DQ7) - eliminates need for external busy polling hardware |
| Fixed Erase/Program Timing | No degradation over 100,000 cycles - removes runtime de-rating logic in system firmware |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602C-70-4C-EKE | Top-boot block protection (FE000H–FFFFFH) instead of bottom-boot; identical timing, voltage, and command set | Used where bootloader resides in highest-address memory region, not lowest | Select only if board layout and firmware expect top-boot architecture |
| MX29LV160ETTI-70G | Same density, 70 ns access, 2.7–3.6 V, but uses different command sequences and lacks Security ID feature | Requires firmware driver modification; no hardware-assisted device identification | Choose when cost sensitivity outweighs need for secure ID or erase-suspend capability |
Compared with SST39VF1602C-70-4C-EKE and MX29LV160ETTI-70G, the SST39VF1601C-70-4C-EKE uniquely combines bottom-boot protection, Erase-Suspend/Resume, and factory/user Security ID - making it optimal for safety-critical or identity-bound embedded systems where firmware partitioning and device authentication are mandatory.

FAQ
What is the boot block configuration of SST39VF1601C-70-4C-EKE?
The SST39VF1601C-70-4C-EKE implements bottom-boot block protection covering the lowest 8 KWord address range (00000H–01FFFH). This hardware protection is activated when WP# is grounded, preventing accidental erase or program of the bootloader region. The protected size and location are fixed per device variant and differ from the top-boot SST39VF1602C series.
Does SST39VF1601C-70-4C-EKE support JEDEC-standard command sets?
Yes, the SST39VF1601C-70-4C-EKE fully conforms to JEDEC standard pinouts and command sets for x16 flash memories. It supports industry-standard operations including Software Data Protection (SDP), Common Flash Interface (CFI) queries, Product Identification, and Security ID access - all implemented via documented three- or six-byte command sequences.
How does the Auto Low Power mode function in SST39VF1601C-70-4C-EKE?
The SST39VF1601C-70-4C-EKE enters Auto Low Power mode automatically after a valid read operation, reducing active current from 9 mA to 3 µA. It exits instantly on any address or control signal transition with no access time penalty. This mode is disabled during power-up if CE# remains low until the first address change.
What are the valid methods to detect completion of a Program or Erase operation in SST39VF1601C-70-4C-EKE?
The SST39VF1601C-70-4C-EKE provides three concurrent detection methods: Data# Polling (DQ7 toggles until completion), Toggle Bits (DQ6 toggles during operation, stops when done), and Ready/Busy# (RY/BY# open-drain pin pulled low during operation). All are valid after defined WE# edge counts per operation type.
Is SST39VF1601C-70-4C-EKE pin-compatible with other 48-pin TSOP flash devices?
The SST39VF1601C-70-4C-EKE uses JEDEC-standard x16 flash pinout for 48-lead TSOP, matching physical pin positions for VDD, VSS, A0–A19, DQ0–DQ15, CE#, OE#, WE#, WP#, RST#, and RY/BY#. However, command sequences, timing, and protection features differ - electrical pin compatibility does not guarantee functional drop-in replacement.
