Product details
Overview
SST39SF010A-70-4C-NHE 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 delivers 10 mA typical active current, 30 µA typical standby current, and supports byte-program and chip-erase functions for embedded firmware storage in industrial controllers.
For engineers reviewing the SST39SF010A-70-4C-NHE datasheet, SST39SF010A-70-4C-NHE pinout, SST39SF010A-70-4C-NHE application, or SST39SF010A-70-4C-NHE equivalent, this page provides verified technical context, JEDEC-compliant pin definitions, SuperFlash® reliability metrics, and real-world use cases for legacy system upgrades and boot code retention.
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. It uses standard microprocessor write sequences to execute JEDEC-compliant command sets-including three-byte software data protection for byte program and six-byte sequences for sector/chip erase.
The SST39SF010A-70-4C-NHE operates in Read, Byte Program, Sector Erase, Chip Erase, and Software Product Identification modes controlled by CE#, OE#, and WE# signals. End-of-write detection is supported via Data# Polling (DQ7) and Toggle Bit (DQ6), both valid after rising-edge timing thresholds aligned to WE#/CE# pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), directly maps to 128 KB of firmware or configuration storage without external address decoding overhead. |
| Read Access Time | 70 ns maximum - enables direct interface with 14 MHz microcontrollers without wait states. |
| Supply Voltage | 4.5V–5.5V single supply - eliminates need for auxiliary voltage rails in 5V legacy systems. |
| Endurance | 10,000 minimum erase/program cycles per sector - validated per JEDEC A117, sufficient for field firmware updates over 10+ years. |
| Data Retention | 100 years minimum at +25°C - ensures long-term integrity of boot code and calibration tables in unpowered storage. |
| Standby Current | 100 µA maximum (CMOS input mode) - reduces quiescent power in battery-backed or low-power sleep states. |
| Byte Program Time | 10 µs maximum - allows rapid patching of small code segments without system-level latency penalties. |
| Sector Erase Time | 25 ms maximum - enables selective reprogramming of 4-Kbyte functional blocks (e.g., parameter banks) without full chip reset. |
Pinout & Package
Package: 32-lead TSOP (Thin Small Outline Package), RoHS-compliant, surface-mount compatible with standard reflow profiles.
| 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 | 8-bit bidirectional data bus with tri-state outputs gated by CE# and OE#; latched internally during writes. |
| CE# | Chip Enable | Active-low chip select; device enters standby (30 µA) when high, enabling multi-device memory mapping. |
| OE# | Output Enable | Active-low output gate; controls data bus visibility independently of CE#, allowing shared bus arbitration. |
| WE# | Write Enable | Active-low write control; initiates byte program, sector erase, or chip erase upon valid command sequence. |
| VDD | Power Supply | 4.5V–5.5V core supply; internal VPP generation eliminates need for external high-voltage programming circuitry. |
| VSS | Ground | Reference return path for all digital and analog functions; decoupling required within 10 mm of VDD pin. |
| NC (Pins 1, 30) | No Connection | Unbonded pins on SST39SF010A; must remain unconnected to avoid signal integrity or ESD risks. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell architecture ensures stable 70 ns read timing and fixed 10 µs program time across full lifecycle - no derating required in system firmware. |
| Hardware + Software Data Protection | Glitch immunity (<5 ns), VDD lockout (<2.5V), and JEDEC-standard 3-byte/6-byte command sequences prevent accidental writes during power transitions. |
| TTL I/O Compatibility | Direct interface with 5V microcontrollers and FPGAs without level-shifting; VIH = 2.0V min, VOH = 2.4V min at 400 µA load. |
| Uniform 4-Kbyte Sectors | 32 independent erasable blocks enable modular firmware updates - e.g., overwrite communication stack without touching bootloader. |
| End-of-Write Detection | DQ7 (Data# Polling) and DQ6 (Toggle Bit) provide deterministic status feedback - eliminates need for fixed delay loops in host firmware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM29LV010B-70EC | 70 ns access, 1-Mbit (128K × 8), but requires 3.0V–3.6V or 4.75V–5.25V dual-supply options; no internal VPP generation. | Not suitable for single-rail 5V systems without external charge pump; higher system BOM cost and layout complexity. | Select only if migrating to 3.3V core logic; verify voltage translation and timing margins before substitution. |
| MX29LV160ETTI-70G | 16-Mbit (2M × 8), 70 ns access, 3.0V supply; supports CFI query and wider command set including suspend/resume. | Higher density enables consolidated memory map; incompatible voltage domain and pinout require PCB redesign. | Use for new designs requiring scalability; not a drop-in replacement due to different address/data bus width and power requirements. |
Compared with AM29LV010B-70EC and MX29LV160ETTI-70G, the SST39SF010A-70-4C-NHE offers unique single 5V operation with integrated VPP, making it optimal for cost-sensitive, space-constrained legacy 5V systems where minimal layout change and proven field reliability are critical.

FAQ
What is the maximum operating temperature range for the SST39SF010A-70-4C-NHE?
The SST39SF010A-70-4C-NHE is rated for commercial operation from 0°C to +70°C and industrial operation from –40°C to +85°C. Its guaranteed performance across this full industrial range makes the SST39SF010A-70-4C-NHE suitable for deployment in factory automation equipment, outdoor kiosks, and vehicle-mounted control units where ambient thermal stress is significant.
Does the SST39SF010A-70-4C-NHE require an external high-voltage supply for programming?
No, the SST39SF010A-70-4C-NHE integrates internal VPP generation and operates entirely from a single 4.5V–5.5V supply for both read and write operations. This eliminates the need for external charge pumps or high-voltage programming circuits, simplifying system design and reducing bill-of-materials cost compared to earlier flash technologies.
How does the SST39SF010A-70-4C-NHE handle inadvertent write operations during power-up or power-down?
The SST39SF010A-70-4C-NHE incorporates three hardware protections: noise/glitch immunity (rejects WE#/CE# pulses <5 ns), VDD power-up/down detection (inhibits writes below 2.5V), and write-inhibit mode (forces safe state when OE# is low or CE#/WE# is high). These features ensure the SST39SF010A-70-4C-NHE remains immune to spurious writes during unstable supply conditions.
Can the SST39SF010A-70-4C-NHE be used in systems requiring JEDEC-standard command compatibility?
Yes, the SST39SF010A-70-4C-NHE fully conforms to JEDEC® standard pinouts and command sets for x8 parallel flash memory. Its byte-program, sector-erase, and chip-erase command sequences align with industry-standard protocols, enabling interoperability with existing flash programming tools and firmware drivers built for JEDEC-compliant devices.
What is the sector architecture of the SST39SF010A-70-4C-NHE and how does it impact firmware updates?
The SST39SF010A-70-4C-NHE features 32 uniform 4-Kbyte sectors, allowing granular erasure of specific functional blocks - such as communication stacks or user-interface assets - without affecting bootloader or calibration data stored elsewhere. This architecture enables robust, field-safe firmware updates and reduces downtime during maintenance, a key advantage of the SST39SF010A-70-4C-NHE in deployed systems.
