Product details
Overview
SST39LF010-45-4C-WHE from Microchip Technology is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 45 ns read access time, single 3.0–3.6 V supply for both read and write operations, and uniform 4 KByte sector-erase architecture. It implements SuperFlash technology with split-gate cells, supports JEDEC-standard x8 pinout, and is used in firmware storage for industrial controllers and embedded boot code applications.
For engineers reviewing the SST39LF010-45-4C-WHE datasheet, SST39LF010-45-4C-WHE pinout, SST39LF010-45-4C-WHE application, or SST39LF010-45-4C-WHE equivalent, key selection criteria include its 45 ns read timing, 3.0–3.6 V operating range, 100,000-cycle endurance, sector-erase capability, and compatibility with standard 8-bit microcontroller buses in space-constrained designs.
Technical Context
This device uses SST's proprietary SuperFlash technology with a split-gate cell and thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports byte-program (20 µs typical), sector-erase (18 ms typical), and chip-erase (70 ms typical) via JEDEC-standard command sequences.
Write status detection is implemented via Data# Polling (DQ7) and Toggle Bit (DQ6); hardware protection includes noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5 V inhibit), and software data protection (SDP) requiring three-byte unlock sequences for programming and six-byte for erasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - provides sufficient space for bootloader, configuration tables, or small firmware images in 8-bit systems. |
| Read Access Time | 45 ns - enables direct execution from flash (XIP) at up to ~14 MHz bus clock without wait states in compatible controllers. |
| Supply Voltage | 3.0–3.6 V - single-supply operation simplifies power design versus dual-rail alternatives; not compatible with 2.7 V systems. |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over product lifetime in industrial monitoring devices. |
| Data Retention | >100 years - ensures long-term reliability for unattended equipment such as utility meters or remote sensors. |
| Sector Size | 4 KByte uniform sectors - allows granular firmware patching without full chip erase, reducing update time and wear. |
| Standby Current | 1 µA typical - minimizes quiescent power in battery-backed or low-power sleep modes. |
Pinout & Package
Package: 32-lead PLCC (Plastic Leaded Chip Carrier), RoHS-compliant, surface-mountable with standard reflow profile (260°C/10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 provide 17-bit addressing for 128K × 8 capacity; A16 is most significant address (AMS) for sector selection during erase. |
| 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; device enters standby (1 µA) when high; required low for all operations except write-inhibit. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; must be low with CE# low for valid read data. |
| WE# | Write Enable | Active-low control for program/erase; initiates internal timing on rising edge; used with CE# for command sequencing. |
| VDD | Power Supply | 3.0–3.6 V supply; powers core logic and memory array; requires local decoupling per JEDEC guidelines. |
| VSS | Ground | Reference ground for all I/O and core functions; must be low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell architecture delivers fixed 20 µs byte-program and 18 ms sector-erase times across full lifecycle-no software de-rating needed. |
| JEDEC x8 Pinout Compliance | Direct drop-in replacement for legacy parallel NOR flash in existing 8-bit bus designs without PCB modification. |
| Hardware + Software Data Protection | Glitch immunity, VDD monitoring, and mandatory 3-byte unlock sequence prevent accidental writes during power transitions or noise events. |
| Toggle Bit & Data# Polling | Real-time write completion detection via DQ6 toggle or DQ7 complement behavior-enables efficient polling without timer overhead. |
| Uniform 4 KByte Sectors | Enables selective firmware updates (e.g., patching only communication stack) while preserving calibration data in other sectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT29LV010A-15JI | 1 Mbit, 150 ns access, 3.0–3.6 V, 100,000 cycles - slower read speed and larger access time. | Not suitable for XIP at >6 MHz; higher latency impacts real-time boot performance. | Select only if system timing budget permits 150 ns read; verify compatibility with existing SDP command flow. |
| SST39VF010-70-4C-WHE | 1 Mbit, 70 ns access, 2.7–3.6 V supply - wider voltage range but slower timing; same pinout and command set. | Supports battery-powered or wide-input-range systems but sacrifices 45 ns performance headroom. | Choose when 2.7 V operation is required; otherwise SST39LF010-45-4C-WHE offers superior speed within 3.3 V systems. |
Compared with AT29LV010A-15JI and SST39VF010-70-4C-WHE, the SST39LF010-45-4C-WHE delivers the fastest read access (45 ns) in its voltage class, making it optimal for time-critical boot and firmware execution, while maintaining identical JEDEC x8 pinout and command compatibility for seamless integration.

FAQ
What is the maximum operating frequency supported by SST39LF010-45-4C-WHE?
The SST39LF010-45-4C-WHE has a 45 ns read access time, supporting reliable operation at up to approximately 14 MHz bus clock frequency in systems with zero wait-state timing. Its performance is validated under JEDEC AC conditions with 30 pF load and 5 ns input rise/fall times. The device does not specify a maximum clock frequency directly but derives timing limits from TRC, TAA, and TOE parameters in Table 12.
Does SST39LF010-45-4C-WHE support 2.7 V operation?
No, the SST39LF010-45-4C-WHE is rated for 3.0–3.6 V operation only, as defined in Table 5 of the datasheet. For 2.7 V compatibility, the SST39VF010-70-4C-WHE variant is specified with 2.7–3.6 V supply range. Attempting to operate SST39LF010-45-4C-WHE below 3.0 V may result in failed program/erase operations or data corruption due to insufficient internal charge pump voltage.
How many address lines does SST39LF010-45-4C-WHE require?
The SST39LF010-45-4C-WHE requires 17 address lines (A0–A16) to access its full 128K × 8 memory space. A16 serves as the most significant address (AMS) for sector selection during erase operations. This matches JEDEC-standard x8 parallel flash addressing and is consistent across all 32-lead PLCC, TSOP, and BGA packages of this device.
Is SST39LF010-45-4C-WHE pin-compatible with SST39LF020 or SST39LF040?
Yes, the SST39LF010-45-4C-WHE shares identical pinout and command set with SST39LF020 and SST39LF040 in the same package type (e.g., 32-lead PLCC), differing only in density (128K × 8 vs. 256K × 8 vs. 512K × 8) and AMS address width (A16 vs. A17 vs. A18). System-level compatibility requires verifying address decoding logic accommodates the larger address space of higher-density variants.
What write protection mechanisms does SST39LF010-45-4C-WHE implement?
The SST39LF010-45-4C-WHE implements dual-layer protection: hardware features include noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5 V inhibit), and write-inhibit mode (OE# low, CE# high, or WE# high); software protection requires mandatory three-byte unlock sequences before byte-program and six-byte sequences before sector/chip-erase operations, per JEDEC-standard SDP.
