Product details
Overview
SST39SF010A-70-4I-NHE-T from Microchip Technology is a 1-Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 70 ns read access time, single 4.5V–5.5V supply operation, and uniform 4-Kbyte sector erase architecture. It features TTL I/O compatibility, JEDEC-standard pinout and command set, and is designed for embedded firmware storage in industrial control systems requiring field-upgradable code.
For engineers reviewing the SST39SF010A-70-4I-NHE-T datasheet, SST39SF010A-70-4I-NHE-T pinout, SST39SF010A-70-4I-NHE-T application, or SST39SF010A-70-4I-NHE-T equivalent, this page delivers verified technical context, real-world timing behavior, sector-level erase validation, SuperFlash® reliability metrics, and direct substitution guidance aligned to JEDEC x8 Flash interface requirements.
Technical Context
This device implements Microchip's proprietary SuperFlash® technology with split-gate cell design and thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional Flash where timing degrades over endurance life. It supports byte-program (≤10 µs), sector erase (≤25 ms), and chip erase (≤100 ms) via standardized six-byte software command sequences.
Operation relies on three control signals-CE#, OE#, and WE#-with dual-mode timing support (WE#- or CE#-controlled), latched address/data buses, and end-of-write detection via Toggle Bit (DQ6) or Data# Polling (DQ7). Hardware protection includes VDD power-up/down detection (<2.5V inhibit), noise/glitch immunity (<5 ns pulse rejection), and write-inhibit mode during power transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), directly maps to 128 KB of firmware or configuration data storage |
| Read Access Time | 70 ns maximum - enables direct execution from flash (XIP) in 14 MHz microcontroller systems |
| Supply Voltage | 4.5V–5.5V single supply - eliminates need for external voltage regulators in 5V legacy industrial designs |
| Endurance | 10,000 program/erase cycles minimum per sector - validated per JEDEC A117 for long-term field reliability |
| Data Retention | 100 years minimum at +85°C - ensures firmware integrity across full industrial temperature lifetime |
| Standby Current | 100 µA maximum (CMOS input) - reduces quiescent power in always-on control modules |
| Byte Program Time | ≤10 µs - allows rapid patch updates without system interruption or complex buffering |
Pinout & Package
32-lead TSOP (Thin Small Outline Package) with standard JEDEC x8 Flash footprint; compatible with automated SMT assembly and reflow profiles per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus supporting full 128K-word addressing; A12 selects 4-Kbyte sector during erase |
| DQ0–DQ7 | Data I/O | Bi-directional 8-bit data bus with tri-state outputs controlled by CE# and OE#; DQ6 = Toggle Bit, DQ7 = Data# Polling |
| CE# | Chip Enable | Active-low device select; must be low for read/write; high-Z output when asserted high |
| OE# | Output Enable | Active-low output gate; decouples data bus during standby or write operations |
| WE# | Write Enable | Active-low write control; initiates internal program/erase timing upon rising edge |
| VDD | Power Supply | 4.5V–5.5V main supply; powers all logic and charge-pump circuitry for erase/program |
| VSS | Ground | Reference return path for all I/O and core logic; requires low-impedance PCB connection |
| NC (Pins 1, 30) | No Connection | Unbonded pins for SST39SF010A; reserved for higher-density variants (A17/A18) |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 10 µs byte-program and 25 ms sector-erase times across full 10,000-cycle lifetime-no firmware derating required |
| JEDEC x8 Command Set | Fully compliant with industry-standard Flash command protocols (e.g., 5555H/2AAAH unlock sequence), ensuring drop-in compatibility with existing BIOS/firmware drivers |
| Dual Write-Detection Methods | Hardware-supported Toggle Bit (DQ6) and Data# Polling (DQ7) enable deterministic, non-blocking status checking without polling overhead |
| Hardware + Software Protection | VDD monitoring, <5 ns glitch rejection, and mandatory 3-byte/6-byte unlock sequences prevent accidental writes during power transitions or noise events |
| Uniform 4-Kbyte Sectors | 32 identical sectors simplify firmware partitioning-e.g., separate boot loader, application, and parameter sectors with independent update capability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT29LV010A-70PU | 1-Mbit, 70 ns, 3.0V–3.6V supply only; lacks SuperFlash® fixed timing; 100K-cycle endurance | Requires separate 3.3V regulator; unsuitable for 5V legacy systems or high-cycle logging | Select only if system operates exclusively at 3.3V and needs higher endurance than SST39SF010A-70-4I-NHE-T's 10K cycles |
| MX29LV160ETTI-70G | 16-Mbit (2M × 8), 70 ns, 3.0V–3.6V; supports CFI query; no 5V compatibility | Higher density but incompatible voltage range; requires PCB redesign for 3.3V I/O and level-shifting | Choose for new 3.3V designs needing larger firmware space and CFI-based auto-detection-avoid for 5V pin-compatible replacement |
Compared with AT29LV010A-70PU and MX29LV160ETTI-70G, the SST39SF010A-70-4I-NHE-T uniquely supports 5V operation with fixed-timing SuperFlash®, making it the only viable option for upgrading legacy industrial 5V systems without modifying power delivery or timing margins.

FAQ
What is the maximum operating temperature range for the SST39SF010A-70-4I-NHE-T?
The SST39SF010A-70-4I-NHE-T is rated for industrial temperature operation from –40°C to +85°C, validated per its DC and AC specifications across this full range. This makes SST39SF010A-70-4I-NHE-T suitable for deployment in factory automation controllers, outdoor telecom equipment, and automotive under-hood modules where ambient thermal stress is significant.
Does the SST39SF010A-70-4I-NHE-T support true 5V operation, or is it 5V-tolerant only?
The SST39SF010A-70-4I-NHE-T requires a true 4.5V–5.5V supply for all read and write operations-it is not 5V-tolerant but fully 5V-native. Its internal charge pump and SuperFlash® cell design are optimized for this range, enabling reliable byte programming and sector erase without external voltage boosting, unlike many 3.3V-only Flash devices.
How does the SST39SF010A-70-4I-NHE-T handle write protection during power-up?
The SST39SF010A-70-4I-NHE-T incorporates hardware write inhibition below 2.5V VDD, plus <5 ns noise immunity on WE#/CE# pins. During power ramp-up, SST39SF010A-70-4I-NHE-T remains in Read mode until VDD exceeds 2.5V, and invalid short pulses are ignored-preventing spurious writes that could corrupt firmware before system initialization completes.
Can the SST39SF010A-70-4I-NHE-T be used in a socketed prototype board with PDIP footprint?
No-the SST39SF010A-70-4I-NHE-T uses a 32-lead TSOP package (NHE suffix), not PDIP. While the pinout is JEDEC-standard and electrically identical to PDIP/PLCC variants, the physical TSOP package requires surface-mount layout and reflow soldering. For socketed prototyping, use SST39SF010A-70-4C-PHE (PDIP) instead.
What is the sector erase time specification for the SST39SF010A-70-4I-NHE-T?
The SST39SF010A-70-4I-NHE-T has a maximum sector erase time of 25 ms, as specified in Table 7-2 of the official datasheet (DS20005022F). This value is guaranteed across temperature and voltage ranges and remains constant over the device's full 10,000-cycle endurance life due to SuperFlash® technology-unlike conventional Flash where erase time increases with wear.
