Product details
Overview
SST39SF010A-70-4C-NHE-T from Microchip Technology is a 1-Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with JEDEC-standard x8 parallel interface, 70 ns read access time, single 4.5V–5.5V supply operation, 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 SST39SF010A-70-4C-NHE-T datasheet, SST39SF010A-70-4C-NHE-T pinout, SST39SF010A-70-4C-NHE-T application, or SST39SF010A-70-4C-NHE-T equivalent, key selection criteria include 70 ns read timing, 100,000-cycle endurance, hardware/software write protection, TTL I/O compatibility, and TSOP-32 packaging for space-constrained PCB layouts.
Technical Context
The SST39SF010A-70-4C-NHE-T implements SuperFlash® split-gate cell technology enabling fixed erase/program times independent of cycle count, eliminating system derating over lifetime. Its control logic supports standard microprocessor bus cycles with CE#, OE#, and WE# inputs governing read, byte program, sector erase, and chip erase operations.
It uses JEDEC-standard command sequences-including three-byte software data protection for programming and six-byte sequences for sector/chip erase-and provides dual end-of-write detection via Data# Polling (DQ7) and Toggle Bit (DQ6), ensuring deterministic timing for host firmware integration without polling overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 1 Mbit (128K × 8), directly replaces EPROMs and earlier flash in legacy 8-bit bus systems |
| Read access time | 70 ns maximum - enables direct connection to 14 MHz microcontrollers without wait states |
| Supply voltage | 4.5V–5.5V - operates across full commercial 5V rail with no external regulator required |
| Endurance | 100,000 program/erase cycles - supports frequent firmware updates in industrial controllers |
| Data retention | 100 years minimum - ensures long-term reliability in unpowered storage applications |
| Active current | 10 mA typical at 14 MHz - low power consumption during active read operations |
| Standby current | 30 µA typical - suitable for battery-backed or low-power sleep modes |
| Sector size | Uniform 4 Kbyte sectors - simplifies firmware partitioning and OTA update management |
Pinout & Package
Package: 32-lead TSOP (Thin Small Outline Package), 8 mm × 13.4 mm body, 0.5 mm lead pitch, RoHS-compliant, surface-mountable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address inputs | 16-bit address bus supporting full 128K-word addressing; A16 is NC for SST39SF010A |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus with latched inputs and tri-state outputs controlled by CE#/OE# |
| CE# | Chip enable | Active-low device select; high-Z output when asserted high, enabling multi-device bus sharing |
| OE# | Output enable | Active-low output gate; decouples data bus from memory during read without disabling chip |
| WE# | Write enable | Active-low control for all write operations (byte program, sector/chip erase) |
| VDD | Power supply | 4.5V–5.5V core and I/O supply; internal VPP generation eliminates external high-voltage circuitry |
| VSS | Ground | Reference return path for all signals and power; separate ground pin improves noise immunity |
| NC | No connection | Pins 1 and 30 are unconnected on SST39SF010A (A18/A17 used only on higher-density variants) |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® technology | Fixed 18 ms sector erase and 70 ms chip erase times - eliminates firmware timing margin growth over product lifetime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM29LV010B-70EC | 70 ns access, 1 Mbit, 3.0V–3.6V supply - requires separate 3.3V rail and level translation for 5V systems | Designed for low-voltage embedded systems; not pin-compatible due to different VCC/VPP pin assignments | Select only if migrating to 3.3V architecture; SST39SF010A-70-4C-NHE-T remains optimal for 5V legacy designs. |
| MX29LV160ETTI-70G | 70 ns access, 16 Mbit (2M × 8), 2.7V–3.6V supply - higher density but incompatible voltage and command set | Targets modern 32-bit processors with wider data buses; lacks hardware write inhibit and has longer erase times | Not suitable as direct alternative; use only in new 3.3V designs requiring larger capacity and different interface protocol. |
Compared with AM29LV010B-70EC and MX29LV160ETTI-70G, the SST39SF010A-70-4C-NHE-T uniquely delivers 5V operation, JEDEC-standard pinout, and SuperFlash® fixed-timing erase/program in a TSOP-32 package - making it the only viable option for maintaining 5V parallel bus compatibility while meeting industrial endurance and retention requirements.
