Product details
Overview
SST39VF010-70-4I-NHE from Microchip Technology is a 1-Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 2.7V–3.6V single-supply write operation, 70 ns read access time, and uniform 4-Kbyte sector erase architecture. It serves as nonvolatile program/data storage in embedded microcontroller systems requiring field-upgradable firmware or configuration data.
For engineers reviewing the SST39VF010-70-4I-NHE datasheet, SST39VF010-70-4I-NHE pinout, SST39VF010-70-4I-NHE application, or SST39VF010-70-4I-NHE equivalent, key selection criteria include voltage range compatibility (2.7V–3.6V), industrial temperature support (−40°C to +85°C), JEDEC-standard x8 flash command set, and SuperFlash® technology's fixed 14 µs byte program time and 18 ms sector erase time.
Technical Context
This device implements Microchip's proprietary SuperFlash® split-gate cell technology, delivering fixed erase/program timing independent of cycle count-unlike conventional flash-enabling stable system timing without software derating. Its control logic supports both CE#- and WE#-controlled command sequences for Byte Program, Sector Erase, and Chip Erase operations.
It features dual software/hardware data protection: hardware-level noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5V inhibit), and JEDEC-compliant three-byte (Program) or six-byte (Erase) Software Data Protection sequences. Output buffers are CMOS-compatible with tri-state control via OE# and CE#.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), providing sufficient space for boot code or small firmware images in resource-constrained systems. |
| Read Access Time | 70 ns maximum - determines minimum bus cycle time when interfacing with 8-bit microcontrollers or FPGAs. |
| Write Voltage Range | 2.7V–3.6V - enables direct integration into 3.3V systems without level-shifting or auxiliary VPP generation. |
| Byte Program Time | 14 µs typical - enables rapid in-system updates of individual configuration bytes without full-sector overhead. |
| Sector Erase Time | 18 ms typical - allows selective reprogramming of 4-Kbyte functional blocks while preserving adjacent data. |
| Data Retention | Greater than 100 years - ensures long-term reliability in unattended or maintenance-free deployments. |
| Endurance | 100,000 program/erase cycles - supports frequent field updates in industrial controllers or communication modules. |
Pinout & Package
The SST39VF010-70-4I-NHE is available in a 32-lead PLCC package (NHE suffix), with pins 1 and 30 designated as No Connection (NC) per datasheet Figure 2-1 and Table 2-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 select 128K address locations; AMS = A16 defines most significant address for sector/block selection. |
| DQ0–DQ7 | Data I/O | Bi-directional 8-bit data bus; outputs tri-stated when CE# or OE# is high; latched during write cycles. |
| CE# | Chip Enable | Active-low chip select; device enters standby (1 µA) when high; required low for all operations except Write Inhibit. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; high disables outputs regardless of CE# state. |
| WE# | Write Enable | Active-low control for write cycles; latches address/data on falling/rising edges per JEDEC command timing. |
| VDD | Power Supply | 2.7V–3.6V supply input; powers core logic and I/O buffers; internal VPP generation eliminates external high-voltage circuitry. |
| VSS | Ground | Reference return path for all signals and power; must be low-impedance for reliable toggle bit and polling operation. |
| NC | No Connection | Pins 1 and 30 are unconnected; must remain floating or tied to ground per PCB layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 14 µs byte program and 18 ms sector erase times across full endurance life-eliminates need for dynamic timing compensation in host firmware. |
| Uniform 4-Kbyte Sectors | Enables granular firmware partitioning: bootloader, application, and parameter sectors can be independently erased and updated. |
| JEDEC-Standard Command Set | Ensures drop-in compatibility with existing x8 flash drivers and BIOS/UEFI firmware stacks without custom command translation. |
| Hardware + Software Data Protection | Prevents accidental writes during power transitions (VDD <1.5V inhibit) and enforces authenticated command sequences (three/six-byte SDP). |
| Industrial Temperature Range | Rated for −40°C to +85°C operation-qualified for use in motor drives, PLCs, and outdoor IoT gateways without thermal derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT29LV010A-12JC | 1-Mbit, 12V VPP required for programming; 120 ns read access; 5V-tolerant I/O. | Requires external high-voltage generator; slower read timing limits high-speed controller interfaces. | Select if legacy 5V system compatibility and VPP availability exist; avoid for new 3.3V designs. |
| SST39VF010-70-4C-NHE | Identical electrical specs but commercial temperature grade (0°C to +70°C) instead of industrial (−40°C to +85°C). | Not qualified for extended temperature environments such as under-hood automotive or outdoor infrastructure. | Choose only for cost-sensitive consumer or lab-grade applications where ambient temperature remains controlled. |

FAQ
What is the operating voltage range for the SST39VF010-70-4I-NHE?
The SST39VF010-70-4I-NHE operates from 2.7V to 3.6V for both read and write functions. This single-supply range eliminates the need for external VPP programming voltage, simplifying power design in 3.3V systems. The SST39VF010-70-4I-NHE maintains full functionality-including 70 ns read access and 14 µs byte programming-across this entire voltage window, as verified in Microchip's DS20005023E datasheet Tables 5-2 and 7-1.
Does the SST39VF010-70-4I-NHE support sector erase, and what is the sector size?
Yes, the SST39VF010-70-4I-NHE supports uniform sector erase with a fixed size of 4 Kbytes per sector. This architecture enables selective reprogramming of functional blocks-such as bootloader or parameter regions-without affecting adjacent data. The SST39VF010-70-4I-NHE achieves typical sector erase time of 18 ms, as specified in DS20005023E page 1, and uses AMS–A12 address lines to select the target sector during the six-byte command sequence.
How does the SST39VF010-70-4I-NHE indicate completion of a program or erase operation?
The SST39VF010-70-4I-NHE provides two hardware-supported status detection methods: Data# Polling (DQ7) and Toggle Bit (DQ6). After initiating a write operation, DQ7 returns complemented data until completion, then true data; DQ6 toggles between 0 and 1 during the operation and stops upon completion. Both are valid after the fourth (program) or sixth (erase) WE# pulse, enabling efficient polling without timer dependencies. These mechanisms are integral to the SST39VF010-70-4I-NHE's real-time operation in interrupt-driven firmware.
What package type and pin count does the SST39VF010-70-4I-NHE use?
The SST39VF010-70-4I-NHE uses a 32-lead Plastic Leaded Chip Carrier (PLCC) package, denoted by the "NHE" suffix. Pin 1 and Pin 30 are No Connection (NC), as confirmed in DS20005023E Figure 2-1 and Table 2-1. This surface-mount package supports reflow soldering up to +260°C and is compatible with standard PLCC sockets used in development and production test fixtures for the SST39VF010-70-4I-NHE.
Is the SST39VF010-70-4I-NHE RoHS compliant and qualified for industrial temperature operation?
Yes, the SST39VF010-70-4I-NHE is RoHS compliant per datasheet Feature list and qualified for industrial temperature operation from −40°C to +85°C, as defined in Table 5-2 of DS20005023E. This rating applies to the "I" grade variant (SST39VF010-70-4I-NHE), distinguishing it from the commercial-grade "C" variant. All units undergo screening per Microchip's industrial qualification standards, ensuring reliability in demanding environments where the SST39VF010-70-4I-NHE is deployed.
