Product details
Overview
SST39LF010-45-4C-MME 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 command set, and is used in embedded firmware storage for industrial controllers and legacy BIOS modules.
For engineers reviewing the SST39LF010-45-4C-MME datasheet, SST39LF010-45-4C-MME pinout, SST39LF010-45-4C-MME application, or SST39LF010-45-4C-MME equivalent, key selection criteria include 45 ns read timing, 3.0–3.6 V VDD compatibility, PLCC-32 package footprint, byte-program capability (≤20 µs), and hardware/software data protection schemes.
Technical Context
This device operates as a nonvolatile x8 parallel interface flash memory with latched address/data bus, requiring CE#, OE#, and WE# control signals. Its SuperFlash architecture delivers fixed erase/program times independent of cycle count-enabling predictable system timing without software de-rating.
It supports three primary operations via JEDEC-compliant command sequences: Byte-Program (three-byte unlock + address/data), Sector-Erase (six-byte sequence with 30H command), and Chip-Erase (six-byte sequence with 10H command). End-of-write detection uses DQ7 Data# Polling and DQ6 Toggle Bit status reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - provides sufficient space for boot code or configuration data in resource-constrained systems |
| Read Access Time | 45 ns - enables direct interfacing with 14 MHz microcontrollers without wait states |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V logic rails and eliminates need for auxiliary voltage regulators |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over product lifetime |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Active Current | 5 mA typical at 14 MHz - minimizes power impact during active read operations |
| Standby Current | 1 µA typical - enables ultra-low-power hold mode in battery-backed systems |
Pinout & Package
Package: 32-lead Plastic Leaded Chip Carrier (PLCC), RoHS compliant, surface-mountable with standard reflow profile (260°C for 10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K × 8 addressing; A16 is most significant address (AMS) |
| DQ0–DQ7 | Data Input/Output | 8-bit bidirectional data bus; tri-stated when CE# or OE# is high; DQ6/DQ7 used for status polling |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; controls device power state (standby if high) |
| OE# | Output Enable | Active-low output gate; allows data read without deselecting chip; required low with CE# for valid read |
| WE# | Write Enable | Active-low write control; initiates byte-program, sector-erase, and chip-erase command sequences |
| VDD | Power Supply | 3.0–3.6 V supply input; powers core logic and memory array; internal VPP generation eliminates external high-voltage source |
| VSS | Ground | Reference ground for all I/O and core circuitry; decoupling capacitor placement critical near this pin |
| NC | No Connection | Pins A17, A18, and NC marked on PLCC layout are unconnected and must remain floating |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell design with thick-oxide tunneling injector enables faster erase (18 ms sector) and lower total energy per operation vs. conventional flash |
| Uniform Sector Architecture | 32 × 4 KByte sectors allow granular firmware updates without erasing entire memory - reduces risk of corruption during partial reprogramming |
| Hardware + Software Data Protection | Glitch immunity (<5 ns pulses rejected), VDD power-up/down detection, and mandatory 3-byte unlock sequence prevent accidental writes during reset or noise events |
| JEDEC-Compliant Interface | Standard x8 pinout and command set ensure drop-in replacement compatibility with other JEDEC flash devices in existing PCB layouts |
| CMOS I/O Compatibility | Input thresholds (VIL = 0.8 V, VIH = 0.7×VDD) and output drive (VOH ≥ VDD−0.2 V, VOL ≤ 0.2 V) guarantee interoperability with 3.3 V microcontrollers and FPGAs |

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, same PLCC-32 package but uses different command set (AMD-style) and lacks Toggle Bit status reporting | Requires firmware driver modification due to non-JEDEC command protocol; no built-in DQ6 status feedback | Select only if legacy AMD-compatible system requires exact pinout and timing match without software changes to status polling logic |
| SST39VF010-70-4C-MFE | Same density and PLCC-32 package but wider 2.7–3.6 V VDD range and slower 70 ns read access; identical SuperFlash architecture and command set | Compatible in systems requiring extended voltage tolerance (e.g., battery-powered designs) where 70 ns timing is acceptable | Choose when broader supply range is needed and 25 ns timing margin is available; fully software-compatible replacement |
Compared with AM29LV010B-45EI, SST39LF010-45-4C-MME offers JEDEC-standard commands and dual-status detection for safer field updates; compared with SST39VF010-70-4C-MFE, it delivers 25 ns faster read performance at the cost of narrower voltage range-ideal for stable 3.3 V rail environments.

FAQ
What is the maximum operating temperature range for SST39LF010-45-4C-MME?
The SST39LF010-45-4C-MME is rated for commercial temperature operation from 0°C to +70°C. It is not specified for industrial (-40°C to +85°C) use-this distinction applies to the SST39VF variant family. The 'C' in the part number explicitly denotes Commercial grade, and thermal validation per DS25023A confirms operation only within this range.
Does SST39LF010-45-4C-MME support both CE#-controlled and WE#-controlled programming?
Yes, SST39LF010-45-4C-MME supports both CE#- and WE#-controlled programming and erase operations, as confirmed in Figures 7 and 8 of DS25023A. The timing parameters (TWP, TCP, TWPH, TCPH) are defined for both control methods, and the device accepts identical command sequences regardless of which signal triggers the operation.
Is SST39LF010-45-4C-MME pin-compatible with SST39LF020 or SST39LF040?
No, SST39LF010-45-4C-MME is not pin-compatible with SST39LF020 or SST39LF040. While all share the same PLCC-32 package, the higher-density variants require A17 or A18 address lines-pins designated as NC on SST39LF010-45-4C-MME are functional address inputs on those parts, making direct substitution electrically invalid.
What does the '-4C-MME' suffix indicate in SST39LF010-45-4C-MME?
The '-4C-MME' suffix breaks down as follows: '-45' = 45 ns read access time; '-4C' = Commercial temperature grade (0°C to +70°C); '-MME' = 32-lead PLCC package with matte tin lead finish, RoHS compliant, and shipped in tube packaging per Microchip's ordering nomenclature in DS25023A.
How is hardware write protection implemented in SST39LF010-45-4C-MME?
SST39LF010-45-4C-MME implements hardware write protection via three mechanisms: (1) noise/glitch rejection for WE# or CE# pulses <5 ns, (2) automatic write inhibition when VDD falls below 1.5 V, and (3) forced write-inhibit when OE# is low, CE# is high, or WE# is high-ensuring safe behavior during power transitions without firmware intervention.
