Product details
Overview
SST39SF010A-55-4I-NHE 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 system firmware storage, BIOS/UEFI code retention, and industrial controller configuration memory.
For engineers reviewing the SST39SF010A-55-4I-NHE datasheet, SST39SF010A-55-4I-NHE pinout, SST39SF010A-55-4I-NHE application, or SST39SF010A-55-4I-NHE equivalent, key selection criteria include JEDEC-standard x8 parallel interface compatibility, hardware/software data protection, 100,000-cycle endurance, and 100-year data retention at commercial temperature range.
Technical Context
This device operates as a nonvolatile parallel-interface Flash memory with TTL I/O compatibility and standard JEDEC pinouts. Its internal SuperFlash® cell architecture enables fixed erase/program times independent of cycle count, eliminating software derating over lifetime.
It supports three primary operations via command sequences: byte programming (max 10 µs), sector erase (max 25 ms), and chip erase (max 100 ms), all using toggle-bit or data# polling for end-of-write detection. Address decoding uses A0–A16 (17 address lines), with NC pins varying by density variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - supports full firmware image storage for 8-bit microcontrollers and legacy BIOS applications. |
| Read Access Time | 55 ns - enables direct execution from flash (XIP) in systems with ≤18 MHz bus timing budgets. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic rails without level-shifting circuitry. |
| Endurance | 10,000 cycles (min) - sufficient for field-updatable firmware with infrequent reprogramming. |
| Data Retention | 100 years (min) - ensures long-term reliability in unpowered industrial deployments. |
| Operating Temp | -40°C to +85°C - qualified for industrial-grade embedded control and networking equipment. |
| Standby Current | 100 µA (max, CMOS input) - reduces quiescent power in battery-backed or low-power sleep modes. |
Pinout & Package
32-lead TSOP (Thin Small Outline Package) with 0.5 mm pitch; RoHS-compliant, surface-mountable, and designed for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A16 is AMS (most significant) for this density. |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus with tri-state outputs controlled by CE# and OE#; latched during write cycles. |
| CE# | Chip Enable | Active-low chip select; device enters standby (30 µA) when high, enabling multi-device bus sharing. |
| OE# | Output Enable | Active-low output gate; allows data read without asserting CE#, useful for memory-mapped I/O arbitration. |
| WE# | Write Enable | Active-low control for byte program, sector erase, and chip erase commands; initiates internal timing sequences. |
| VDD | Power Supply | 4.5–5.5 V supply input; internally generates VPP for programming, eliminating external high-voltage circuitry. |
| VSS | Ground | Reference return path for all signals and power; decoupling required within 10 mm of VDD pin. |
| NC (Pins 1, 30) | No Connection | Unbonded pins for SST39SF010A; Pin 1 = NC, Pin 30 = NC - must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell design delivers fixed 10 µs byte program and 25 ms sector erase times across full lifecycle - no software timing adjustments needed. |
| JEDEC x8 Standard Compliance | Pinout and command set match industry-standard parallel Flash devices, enabling drop-in replacement in existing 8-bit memory interfaces. |
| Hardware + Software Data Protection | Glitch immunity (<5 ns), VDD power-up/down detection, and mandatory 3-byte/6-byte command sequences prevent accidental writes during reset or noise events. |
| End-of-Write Detection | Dual status methods - Toggle Bit (DQ6) and Data# Polling (DQ7) - allow host CPU to poll asynchronously without dedicated interrupt lines. |
| Uniform 4-Kbyte Sectors | 32 independent sectors enable granular firmware updates (e.g., bootloader vs. application partition) without erasing entire memory array. |

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, 3.0 V core (3.0–3.6 V), requires external VPP for programming | Lower voltage operation; not pin-compatible due to different VPP pin assignment and command set | Select for 3.3 V systems where voltage scaling is critical; requires redesign of power and timing logic. |
| MX29LV160CBTI-55G | 55 ns access, 16-Mbit (2M × 8), 3.0 V supply, CFI-compliant command set | Higher density and different command protocol; incompatible with SST39SF010A's JEDEC sequence | Choose for new designs needing larger code space and standardized CFI interface; not a drop-in replacement. |
Compared with AM29LV010B-55EC and MX29LV160CBTI-55G, the SST39SF010A-55-4I-NHE offers native 5 V operation with integrated VPP generation and JEDEC-standard command compatibility - simplifying legacy 5 V system upgrades without voltage translation or firmware changes.

FAQ
What is the maximum byte program time for SST39SF010A-55-4I-NHE?
The SST39SF010A-55-4I-NHE has a maximum byte program time of 10 µs, as specified in Table 7-2 of the datasheet. This value is guaranteed across the full industrial temperature range (-40°C to +85°C) and 4.5–5.5 V supply. The SST39SF010A-55-4I-NHE achieves this performance using internal VPP generation and SuperFlash® technology, eliminating external high-voltage circuitry while maintaining consistent timing regardless of program cycle count.
Does SST39SF010A-55-4I-NHE support sector erase, and what is the sector size?
Yes, the SST39SF010A-55-4I-NHE supports uniform sector erase with a fixed size of 4 Kbytes per sector, resulting in 32 total sectors for its 128K × 8 organization. Sector erase is initiated via a six-byte software command sequence and completes in up to 25 ms. This granularity allows targeted firmware updates without disturbing unrelated code or configuration data - a key requirement for field-upgradable embedded systems using the SST39SF010A-55-4I-NHE.
What package type is used for SST39SF010A-55-4I-NHE?
The SST39SF010A-55-4I-NHE is packaged in a 32-lead TSOP (Thin Small Outline Package) with standard 0.5 mm lead pitch and RoHS-compliant finish. This surface-mount package is optimized for high-density PCB layouts and automated assembly. Pin 1 is NC (no connection), and Pin 30 is also NC for this 1-Mbit variant - both must remain unconnected per Microchip's datasheet DS20005022F, page 3.
How does SST39SF010A-55-4I-NHE indicate completion of a write operation?
The SST39SF010A-55-4I-NHE provides two hardware-supported status detection methods: Toggle Bit (DQ6) and Data# Polling (DQ7). During internal program or erase, DQ6 toggles between 0 and 1; cessation indicates completion. DQ7 returns complemented data until completion, then true data. Both methods are valid after the fourth (program) or sixth (erase) WE# pulse edge. These mechanisms eliminate need for fixed delay loops and enable efficient host CPU utilization during SST39SF010A-55-4I-NHE write cycles.
Is SST39SF010A-55-4I-NHE compatible with JEDEC-standard x8 parallel Flash interfaces?
Yes, the SST39SF010A-55-4I-NHE conforms fully to JEDEC® standard pin assignments and command sets for x8 parallel Flash memories. Its pinout matches industry-standard 32-pin configurations, and its command sequences (e.g., 3-byte load for programming, 6-byte for sector erase) align with JEDEC JESD21-C. This compliance enables direct substitution in legacy 5 V systems originally designed for other JEDEC-compliant Flash devices - a core design objective of the SST39SF010A-55-4I-NHE.
