Product details
Overview
SST39LF010-55-4C-NHE from Microchip Technology is a 1-Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 55 ns read access time, single 3.0V–3.6V supply operation, and uniform 4-Kbyte sector erase architecture. It delivers 100,000 program/erase cycles endurance and >100-year data retention, and is used in embedded firmware storage for industrial controllers and legacy BIOS modules where reliable in-system reprogrammability is required.
For engineers reviewing the SST39LF010-55-4C-NHE datasheet, SST39LF010-55-4C-NHE pinout, SST39LF010-55-4C-NHE application, or SST39LF010-55-4C-NHE equivalent, key selection criteria include its JEDEC-standard x8 parallel interface, 32-pin PLCC/TSOP packaging, SuperFlash® low-energy erase/program timing, and hardware/software data protection schemes for robust system-level firmware updates.
Technical Context
This device implements a split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, enabling fixed erase and program times independent of accumulated cycling-unlike conventional flash technologies where timing degrades over endurance life. Its control logic supports standard microprocessor bus timing with CE#/OE#/WE# handshaking and latched address/data paths.
It operates exclusively in asynchronous parallel mode with no internal clock; all write operations (Byte Program, Sector Erase, Chip Erase) are initiated via JEDEC-compliant six-byte software command sequences, and completion is verified using either Data# Polling (DQ7) or Toggle Bit (DQ6) status detection-both accessible without halting host CPU execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), providing sufficient space for boot code or configuration data in resource-constrained 8-bit/16-bit systems. |
| Read Access Time | 55 ns max - enables direct connection to 14 MHz microcontrollers without wait states in most designs. |
| Supply Voltage | 3.0V–3.6V - compatible with legacy 3.3V logic rails and eliminates need for dedicated VPP programming voltage. |
| Endurance | 100,000 program/erase cycles - supports frequent field firmware updates over product lifetime. |
| Data Retention | Greater than 100 years - ensures long-term reliability in unpowered storage applications such as industrial calibration tables. |
| Active Current | 5 mA typical at 14 MHz - reduces power budget impact during active read operations in battery-backed systems. |
| Standby Current | 1 µA typical - enables ultra-low-power sleep modes in always-on embedded devices. |
Pinout & Package
Package: 32-lead PLCC (Plastic Leaded Chip Carrier) with standard JEDEC x8 Flash pinout; RoHS compliant, commercial temperature range (0°C to +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 select byte location; A16 is MSB for 128K×8 addressing (0x0000–0x1FFFF); unused pins are NC per package variant. |
| DQ0–DQ7 | Data I/O | Bidirectional 8-bit data bus; outputs tri-state when CE# or OE# high; latched during write cycles. |
| CE# | Chip Enable | Active-low chip select; device enters standby (1 µA) when high; required low for all read/write operations. |
| OE# | Output Enable | Active-low output gate; controls DQ0–DQ7 drivers independently of CE# to support multiplexed bus sharing. |
| WE# | Write Enable | Active-low write strobe; initiates latching of address/data and triggers internal program/erase state machine. |
| VDD | Power Supply | 3.0V–3.6V supply input; powers core logic and SuperFlash® array; internally generates VPP for tunneling. |
| VSS | Ground | Reference ground for all I/O and core circuitry; requires low-impedance PCB return path. |
| NC | No Connection | Pins 1, 6, 9, 29, 30 are unconnected in 32-lead PLCC package for SST39LF010; must be left floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 18 ms sector erase and 70 ms chip erase times regardless of cycle count-eliminates software derating and simplifies timing-critical firmware design. |
| JEDEC-Compliant Command Set | Fully interoperable with industry-standard x8 Flash controllers and bootloader firmware without custom driver development. |
| Dual Write Completion Detection | Simultaneous support for Data# Polling (DQ7) and Toggle Bit (DQ6) allows flexible, non-blocking status polling in real-time OS or bare-metal environments. |
| Hardware + Software Data Protection | Glitch immunity (<5 ns pulses rejected), VDD power-up/down detection, and mandatory 3-byte/6-byte command sequences prevent accidental writes during brown-out or reset conditions. |
| Low-Energy Programming | Consumes less total energy per erase/program operation than competing NOR flash due to lower current draw and shorter timing-critical for thermally constrained enclosures. |
Applications
| Industrial PLC Firmware Storage | Legacy PC BIOS/UEFI Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM29LV010B-55EC | 55 ns access, 3.0V–3.6V supply, but uses AMD-style command set and lacks Toggle Bit detection; 10,000-cycle endurance rating. | Requires modified bootloader code for erase/write commands; unsuitable for systems relying on DQ6 polling for real-time status. | Select only if existing AMD-compatible firmware infrastructure exists and endurance >10k cycles is sufficient. |
| SST39VF010-70-4C-NHE | Same density and pinout, but 2.7V–3.6V supply range and 70 ns read access; otherwise identical SuperFlash® architecture and command set. | Supports wider voltage tolerance in battery-powered or mixed-voltage systems, but sacrifices 15 ns speed margin for compatibility. | Choose when board-level VDD varies below 3.0V or when SST39LF010-55-4C-NHE is unavailable; no PCB change required. |
Compared with AM29LV010B-55EC, SST39LF010-55-4C-NHE offers 10× higher endurance and deterministic timing, while SST39VF010-70-4C-NHE trades 15 ns speed for broader supply flexibility-making the LF variant optimal for stable 3.3V systems demanding maximum reliability and performance.

FAQ
What is the operating voltage range for SST39LF010-55-4C-NHE?
The SST39LF010-55-4C-NHE operates from 3.0V to 3.6V DC. This single-supply range eliminates the need for external VPP programming voltage and ensures compatibility with standard 3.3V logic families. Operation outside this range-especially below 3.0V-may result in unreliable write operations or data corruption, as confirmed by Microchip's DS20005023E specification.
Does SST39LF010-55-4C-NHE support both hardware and software write protection?
Yes, SST39LF010-55-4C-NHE implements dual-layer protection: hardware features include noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (write inhibited below 1.5V), and write-inhibit mode (via OE#, CE#, or WE# states); software protection requires validated 3-byte (program) or 6-byte (erase) command sequences per JEDEC standard, shipped enabled by default.
What package type is used for SST39LF010-55-4C-NHE?
SST39LF010-55-4C-NHE is supplied in a 32-lead PLCC (Plastic Leaded Chip Carrier) package with standard JEDEC x8 Flash pinout. Pin 1 is NC, and pins 6, 9, 29, and 30 are also unconnected-verified from Microchip's DS20005023E page 3 pin assignment diagrams for the SST39LF010 variant.
How is write completion detected on SST39LF010-55-4C-NHE?
SST39LF010-55-4C-NHE supports two concurrent methods: Data# Polling (monitoring DQ7 for true data vs. complement) and Toggle Bit (monitoring DQ6 for state alternation). Both become valid after the fourth (program) or sixth (erase) WE# pulse rising edge, enabling non-blocking status checks without halting host processor execution.
Is SST39LF010-55-4C-NHE pin-compatible with SST39VF010-70-4C-NHE?
Yes, SST39LF010-55-4C-NHE and SST39VF010-70-4C-NHE share identical 32-pin PLCC/TSOP footprints, pin assignments, and command sets. The only functional differences are read access time (55 ns vs. 70 ns) and supply range (3.0V–3.6V vs. 2.7V–3.6V); no PCB redesign is needed when substituting between them in compatible voltage environments.
