Product details
Overview
SST39SF010A-55-4C-NHE-T from Microchip Technology is a 1-Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 55 ns read access time, single 4.5V–5.5V supply operation, and uniform 4-Kbyte sector erase architecture. It implements SuperFlash® split-gate technology for high reliability and is used in embedded firmware storage, BIOS/UEFI code storage, and industrial controller configuration memory.
For engineers reviewing the SST39SF010A-55-4C-NHE-T datasheet, SST39SF010A-55-4C-NHE-T pinout, SST39SF010A-55-4C-NHE-T application, or SST39SF010A-55-4C-NHE-T equivalent, key selection criteria include JEDEC-standard x8 parallel interface compatibility, hardware/software data protection, 100,000-cycle endurance, and TSOP-32 packaging for space-constrained PCB layouts.
Technical Context
This device operates as a nonvolatile parallel-interface Flash memory with TTL-compatible I/O, supporting byte-program, sector-erase, and chip-erase commands via standard microprocessor write sequences. Its control logic responds to CE#, OE#, and WE# signals to manage read, program, and erase states, with internal VPP generation eliminating external high-voltage requirements.
End-of-write detection uses dual status methods: Data# Polling (DQ7) and Toggle Bit (DQ6), both valid after defined WE#/CE# edge counts. The memory array is organized as 128K × 8 with A0–A16 address lines (AMS = A16), and all operations conform to JEDEC-standard pinouts and command sets for x8 Flash EEPROMs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - supports full BIOS or boot loader storage in legacy x86 and microcontroller-based systems. |
| Read Access Time | 55 ns - enables direct execution from flash (XIP) in timing-critical embedded applications without wait states at 14 MHz bus clock. |
| Supply Voltage | 4.5V–5.5V - compatible with standard 5V TTL logic families and legacy industrial power rails. |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in industrial controllers. |
| Data Retention | 100 years - ensures long-term configuration storage without battery backup in unattended equipment. |
| Sector Size | 4 Kbytes uniform sectors - allows granular firmware patching without erasing entire memory image. |
| Standby Current | 30 µA typical - minimizes quiescent power in always-on embedded systems with infrequent update cycles. |
Pinout & Package
Package: 32-lead TSOP (Thin Small Outline Package), RoHS-compliant, surface-mountable with 0.5 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus (AMS = A16) selects one of 131,072 bytes; A12–A0 used for sector address selection during erase. |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus; outputs tri-stated when CE# or OE# is high; latched internally during write cycles. |
| CE# | Chip Enable | Active-low chip select; device enters standby mode (30 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; must be low with CE# for valid read output. |
| WE# | Write Enable | Active-low write control; initiates byte program, sector erase, or chip erase when CE# is also low. |
| VDD | Power Supply | 4.5V–5.5V main supply; powers core logic and I/O buffers; internal VPP generator eliminates external high-voltage circuitry. |
| VSS | Ground | Reference ground for all digital and analog functions; decoupling capacitor required near VDD/VSS pins. |
| NC | No Connection | Pins 1 and 30 are unconnected for SST39SF010A; no PCB routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell design delivers fixed 55 ns read and 14 µs byte program times independent of erase/program cycle count - eliminates software derating over product lifetime. |
| Hardware + Software Data Protection | Glitch immunity (<5 ns pulses rejected), VDD power-up/down detection (<2.5V inhibit), and JEDEC-standard 3-byte/6-byte command sequences prevent accidental writes during reset or noise events. |
| Uniform Sector Architecture | 32 × 4-Kbyte sectors enable selective firmware updates - avoids full chip erase and reduces field update time by >95% versus monolithic erase schemes. |
| Status Detection Methods | Dual asynchronous end-of-write indicators: Data# Polling (DQ7 toggles complement/data) and Toggle Bit (DQ6 toggles 0/1) - allows host CPU to perform other tasks during erase/program latency. |
| TTL I/O Compatibility | Direct interface with 5V microcontrollers and FPGAs without level-shifting; VIH = 2.0V min, VOL = 0.4V max at 2.1 mA load - ensures robust noise margin in industrial environments. |

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-55EC | 55 ns access, 1-Mbit (128K × 8), 3.0V–3.6V supply only - requires level shifters for 5V systems. | Lacks hardware write-inhibit on power-up; relies solely on software protection. | Select when migrating to 3.3V-only designs; avoid in mixed-voltage 5V legacy systems. |
| MX29LV160CBTI-55G | 55 ns access, 16-Mbit (2M × 8), 2.7V–3.6V supply - higher density but incompatible voltage and command set. | Uses different sector architecture (16 × 8-Kbyte + 2 × 32-Kbyte + 1 × 64-Kbyte) and AMD-style command sequences. | Use only if redesigning for 3.3V and requiring larger capacity; not drop-in replaceable. |
Compared with AM29LV010B-55EC and MX29LV160CBTI-55G, the SST39SF010A-55-4C-NHE-T uniquely combines 5V operation, JEDEC-standard command compatibility, and integrated hardware write-inhibit - making it the only viable option for maintaining legacy 5V embedded systems without board-level changes.

FAQ
What is the maximum operating temperature range for the SST39SF010A-55-4C-NHE-T?
The SST39SF010A-55-4C-NHE-T is rated for commercial operation from 0°C to +70°C and industrial operation from -40°C to +85°C. Its guaranteed performance specifications-including 55 ns read access time and 100,000-cycle endurance-are validated across the full industrial temperature range, making SST39SF010A-55-4C-NHE-T suitable for deployment in factory automation and outdoor infrastructure equipment.
Does the SST39SF010A-55-4C-NHE-T require an external high-voltage supply for programming?
No, the SST39SF010A-55-4C-NHE-T integrates an internal charge pump that generates the required programming voltage (VPP) from the standard 4.5V–5.5V VDD supply. This eliminates the need for external high-voltage circuitry, simplifying board design and reducing BOM cost-confirming that SST39SF010A-55-4C-NHE-T operates fully from a single 5V rail during all read, program, and erase operations.
How does the SST39SF010A-55-4C-NHE-T indicate completion of a byte program operation?
The SST39SF010A-55-4C-NHE-T provides two hardware-supported status detection methods: Data# Polling (monitoring DQ7 for true data return) and Toggle Bit (monitoring DQ6 for cessation of 0/1 toggling). Both become valid after the rising edge of the fourth WE# or CE# pulse, enabling the host processor to poll asynchronously without fixed timing delays-ensuring deterministic SST39SF010A-55-4C-NHE-T integration into real-time firmware update routines.
Can the SST39SF010A-55-4C-NHE-T be used as a direct replacement for the SST39SF020A or SST39SF040 in existing designs?
No-while pin-compatible and sharing identical command sets, the SST39SF010A-55-4C-NHE-T has only 128K × 8 organization (A0–A16), whereas SST39SF020A uses A0–A17 and SST39SF040 uses A0–A18. Using SST39SF010A-55-4C-NHE-T in a design expecting 2-Mbit or 4-Mbit addressing will result in address wraparound and memory corruption; it is not a functional substitute outside its specified 1-Mbit capacity.
What package type is used for the SST39SF010A-55-4C-NHE-T, and what are its mounting requirements?
The SST39SF010A-55-4C-NHE-T uses a 32-lead TSOP (Thin Small Outline Package) with 0.5 mm lead pitch and RoHS-compliant finish. It requires standard reflow soldering per J-STD-020, with peak temperature ≤240°C for 3 seconds. Board layout must include dedicated VDD/VSS decoupling (0.1 µF ceramic) adjacent to pins 16 and 32, and NC pins (1 and 30) must remain unconnected-key mechanical and thermal constraints for reliable SST39SF010A-55-4C-NHE-T assembly.
