Product details
Overview
SST39LF010-45-4C-NHE from Microchip Technology is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 45 ns read access time, 3.0–3.6 V single-supply operation, and uniform 4 KB sector-erase architecture. It implements SuperFlash technology for high reliability in embedded firmware storage, BIOS code storage, and configuration memory applications.
For engineers reviewing the SST39LF010-45-4C-NHE datasheet, SST39LF010-45-4C-NHE pinout, SST39LF010-45-4C-NHE application, or SST39LF010-45-4C-NHE equivalent, key selection criteria include JEDEC-standard x8 parallel interface timing, hardware/software data protection, toggle-bit and data# polling status detection, and compatibility with legacy 32-pin PLCC-based board layouts.
Technical Context
This device uses SST's proprietary split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports byte-program, sector-erase (4 KB), and chip-erase operations via JEDEC-standard command sequences executed over standard microprocessor bus cycles.
Read and write operations are controlled by CE#, OE#, and WE# signals with latched address/data buses. End-of-write detection is implemented via DQ6 (toggle bit) and DQ7 (data# polling), both valid after the fourth (program) or sixth (erase) WE#/CE# pulse edge - no external timing circuitry required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - supports full BIOS or boot loader image storage in space-constrained designs |
| Read Access Time | 45 ns - enables direct execution from flash (XIP) in systems with ≤22 MHz bus timing budgets |
| Supply Voltage | 3.0–3.6 V - compatible with 3.3 V logic rails without level-shifting or auxiliary regulators |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates across 10+ years of industrial deployment |
| Data Retention | >100 years - ensures nonvolatile storage integrity without refresh in unpowered storage scenarios |
| Active Current | 5 mA typical at 14 MHz - reduces system power budget impact during active read operations |
| Standby Current | 1 µA typical - enables ultra-low-power retention in battery-backed or energy-harvesting systems |
Pinout & Package
Package: 32-lead PLCC (Plastic Leaded Chip Carrier), RoHS-compliant, 11.43 mm × 11.43 mm footprint with J-lead geometry suitable for through-hole or surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 provide 17-bit addressing for full 128K × 8 memory space; A16 is most significant address for SST39LF010 |
| DQ0–DQ7 | Data Input/Output | 8-bit bidirectional data bus; tri-stated when CE# or OE# is high; latched internally during write cycles |
| CE# | Chip Enable | Active-low chip select - must be low to enable read/write; high state places device in standby (1 µA) |
| OE# | Output Enable | Active-low output gate - controls data bus drive; used with CE# to manage read timing and bus contention |
| WE# | Write Enable | Active-low control for byte-program and erase command initiation; latches address/data on falling/rising edges per JEDEC sequence |
| VDD | Power Supply | 3.0–3.6 V supply input - powers core logic and memory array; requires local 0.1 µF decoupling |
| VSS | Ground | Reference ground for all I/O and internal circuits - must be low-impedance connection to system GND plane |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector delivers stable 45 ns read timing and fixed 14 µs byte-program time across full lifecycle |
| JEDEC-Compliant Command Set | Standard 3-byte program and 6-byte erase sequences ensure drop-in compatibility with existing flash controller firmware |
| Hardware + Software Data Protection | Glitch filtering (<5 ns pulses rejected), VDD power-up/down detection, and mandatory 3-byte unlock sequence prevent accidental writes |
| Uniform 4 KB Sector Architecture | Enables granular firmware updates without erasing entire device - critical for fail-safe OTA update implementations |
| Status Detection via DQ6/DQ7 | Toggle Bit (DQ6) and Data# Polling (DQ7) allow host CPU to poll completion without timers or interrupts - simplifies driver development |
Applications
| Embedded Boot Code Storage | Industrial PLC Configuration Memory |
|---|---|
Use Scenario: Storing boot loader and initial firmware image in microcontroller-based edge devices requiring cold-start reliability. IC Role / Device Role / Timing Role: Nonvolatile parallel x8 memory mapped to processor address space; accessed during reset vector fetch and early initialization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AM29LV010B-45EI | 45 ns access, 3.0–3.6 V, 1 Mbit x8, but uses AMD-style command set and lacks toggle-bit status reporting | Requires firmware modification for erase/write commands; no DQ6 polling support increases driver complexity | Select only if existing AMD-compatible controller firmware is reused and timing margin allows 50 ns worst-case latency |
| SST39VF010-70-4C-NHE | Same density and package, but 2.7–3.6 V supply range and 70 ns read access time; lower voltage tolerance, slower timing | Suitable for battery-powered systems needing wider VDD range, but incompatible with 45 ns timing-critical boot paths | Choose for cost-sensitive, low-power applications where 70 ns read delay is acceptable and 2.7 V operation is required |
Compared with AM29LV010B-45EI, SST39LF010-45-4C-NHE offers simpler status monitoring and JEDEC compatibility; compared with SST39VF010-70-4C-NHE, it provides tighter timing for high-speed boot sequences while sacrificing low-voltage operation.

FAQ
What is the maximum operating frequency supported by SST39LF010-45-4C-NHE?
The SST39LF010-45-4C-NHE does not specify a maximum clock frequency, as it is an asynchronous parallel flash device. Its 45 ns read access time corresponds to a maximum effective bus speed of approximately 22 MHz for zero-wait-state operation. System timing must comply with AC parameters including TAA (45 ns), TOE (30 ns), and TRC (45 ns) under 3.0–3.6 V and 0°C to +70°C conditions. SST39LF010-45-4C-NHE requires no external clock signal.
Does SST39LF010-45-4C-NHE support sector-erase only, or also chip-erase?
SST39LF010-45-4C-NHE supports both sector-erase (uniform 4 KB sectors) and chip-erase operations. Sector-erase uses a six-byte command sequence ending with 30H and a sector address; chip-erase uses the same six-byte sequence ending with 10H. Typical sector-erase time is 18 ms and chip-erase time is 70 ms. Both operations use DQ6 toggle-bit or DQ7 data# polling for completion detection. SST39LF010-45-4C-NHE guarantees these timings across its full rated temperature and voltage range.
Is SST39LF010-45-4C-NHE pin-compatible with older 27C010 EPROMs?
SST39LF010-45-4C-NHE is functionally and pin-compatible with 27C010 EPROMs in 32-lead PLCC packages, sharing identical pin assignments for A0–A16, DQ0–DQ7, CE#, OE#, WE#, VDD, and VSS. However, it replaces UV-erasable programming with electrical byte-program and sector-erase, and requires different write command sequences. SST39LF010-45-4C-NHE retains the same 32-pin PLCC footprint and timing interface, enabling direct socket replacement in many legacy designs.
What data protection mechanisms are built into SST39LF010-45-4C-NHE?
SST39LF010-45-4C-NHE implements dual-layer data protection: hardware-level noise/glitch filtering (rejects WE#/CE# pulses <5 ns), VDD power-up/down detection (inhibits writes below 1.5 V), and write-inhibit mode (OE# low, CE# high, or WE# high); plus software-level JEDEC-standard three-byte unlock sequence for programming and six-byte sequence for erasing. SST39LF010-45-4C-NHE ships with software data protection permanently enabled, preventing accidental writes during power transitions.
Can SST39LF010-45-4C-NHE operate in industrial temperature range?
No - SST39LF010-45-4C-NHE is specified only for commercial temperature range (0°C to +70°C), as indicated by the "C" suffix in its part number. For industrial temperature operation (–40°C to +85°C), the SST39VF010-70-4I-NHE variant is required, which uses a 2.7–3.6 V supply and has 70 ns access time. SST39LF010-45-4C-NHE's 3.0–3.6 V supply range and 45 ns timing are optimized for commercial-grade applications where ambient thermal stability is assured.
