Product details
Overview
SST39LF010-55-4C-NHE-T 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 for embedded firmware storage in industrial control systems.
For engineers reviewing the SST39LF010-55-4C-NHE-T datasheet, SST39LF010-55-4C-NHE-T pinout, SST39LF010-55-4C-NHE-T application, or SST39LF010-55-4C-NHE-T equivalent, key selection criteria include JEDEC-standard x8 Flash pinout compatibility, SuperFlash® low-energy erase/program timing, hardware/software write protection, and 32-lead PLCC package suitability for legacy board layouts.
Technical Context
This device implements Microchip's proprietary SuperFlash® split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional Flash where timing degrades over endurance life. Its command-set architecture follows JEDEC standard x8 Flash protocols, requiring six-byte software sequences for sector/chip erase and three-byte sequences for byte programming.
Operation relies on dual control signals (CE# and OE# for read, CE#/WE# for write), latched address/data buses, and end-of-write detection via Toggle Bit (DQ6) or Data# Polling (DQ7). The 32-pin PLCC package supports standard microprocessor bus interfacing with CMOS I/O compatibility and noise/glitch immunity below 5 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - provides sufficient space for boot code, configuration tables, or small firmware images in resource-constrained systems. |
| Read Access Time | 55 ns - enables direct execution from flash (XIP) at up to ~14 MHz system clock without wait states in compatible controllers. |
| Supply Voltage | 3.0V–3.6V - compatible with standard 3.3V logic rails and eliminates need for auxiliary voltage regulators. |
| Endurance | 100,000 cycles - supports field-updatable firmware with multi-year service life under typical reprogramming schedules. |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications such as calibration data or security keys. |
| Sector Size | 4 Kbytes uniform - allows granular firmware updates without erasing entire device, minimizing downtime during field upgrades. |
| Active Current | 5 mA typical @14 MHz - reduces power budget impact in always-on embedded systems compared to parallel NOR alternatives. |
Pinout & Package
Package: 32-lead Plastic Leaded Chip Carrier (PLCC), RoHS-compliant, surface-mountable with standard reflow profile (260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 select 128K-byte address space; AMS = A16 for SST39LF010, used to select target sector during erase. |
| DQ0–DQ7 | Data I/O | Bi-directional 8-bit data bus; outputs tri-stated when CE# or OE# high; latched internally during write cycles. |
| CE# | Chip Enable | Active-low chip select; device enters standby mode (1 µA) when high, enabling low-power system sleep states. |
| OE# | Output Enable | Active-low output gate; controls data bus drive without affecting internal state-critical for shared-bus arbitration. |
| WE# | Write Enable | Active-low write strobe; initiates byte program, sector erase, or chip erase when combined with CE# low per JEDEC command sequence. |
| VDD | Power Supply | 3.0V–3.6V main supply; includes internal VPP generation-no external high-voltage pump required. |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection to minimize noise coupling. |
| NC | No Connection | Pins 1, 6, 9, 29, and 30 are unconnected per datasheet-must remain floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 18 ms sector erase and 70 ms chip erase times across full endurance life-eliminates software derating and simplifies timing-critical firmware design. |
| Hardware Write Inhibit | Automatic lockout when VDD < 1.5V or WE#/CE#/OE# glitch < 5 ns-prevents corruption during brown-out or EMI events without external supervision circuits. |
| Software Data Protection | JEDEC-standard 3-byte (program) and 6-byte (erase) command sequences-enables secure, controller-agnostic firmware update protocols. |
| End-of-Write Detection | Dual-mode status reporting via Toggle Bit (DQ6) or Data# Polling (DQ7)-allows host CPU to perform background tasks while flash executes non-blocking operations. |
| CMOS I/O Compatibility | VIH = 0.7VDD, VIL = 0.8V, VOH = VDD−0.2V, VOL = 0.2V-ensures interoperability with 3.3V microcontrollers, FPGAs, and ASICs without level-shifting. |

FAQ
What is the maximum operating frequency supported by SST39LF010-55-4C-NHE-T?
The SST39LF010-55-4C-NHE-T does not specify a maximum clock frequency, as it is an asynchronous parallel Flash device. Its 55 ns read access time corresponds to a theoretical maximum bus toggle rate of ~14 MHz-meaning the host controller must observe minimum cycle times (TRC ≥ 55 ns) between successive read operations. SST39LF010-55-4C-NHE-T operates without an internal clock and relies entirely on CE#, OE#, and WE# timing compliance per Table 7-1.
Does SST39LF010-55-4C-NHE-T support both sector and chip erase modes?
Yes, SST39LF010-55-4C-NHE-T supports both sector erase (uniform 4-Kbyte blocks) and full-chip erase. Sector erase completes in 18 ms typical and uses a six-byte command sequence with sector address; chip erase takes 70 ms typical and uses a separate six-byte sequence targeting address 5555H. Both modes support end-of-operation detection via Toggle Bit (DQ6) or Data# Polling (DQ7), enabling efficient host polling without fixed delays.
What package type is used for SST39LF010-55-4C-NHE-T?
SST39LF010-55-4C-NHE-T uses a 32-lead Plastic Leaded Chip Carrier (PLCC) package, as confirmed by the "NHE" suffix in the part number and Figure 2-1 in DS20005023E. This surface-mount package features a square footprint with J-leads, is RoHS-compliant, and supports standard reflow profiles up to 260°C for 10 seconds. Pin 1 is NC, and pins 6, 9, 29, and 30 are also unconnected per datasheet specifications.
How does SST39LF010-55-4C-NHE-T handle power-up write protection?
SST39LF010-55-4C-NHE-T incorporates hardware write inhibit that blocks all programming operations when VDD falls below 1.5V-preventing spurious writes during power ramp-up or brown-out conditions. Additionally, WE#, CE#, and OE# pulses shorter than 5 ns are ignored, providing immunity to electrical noise. SST39LF010-55-4C-NHE-T ships with Software Data Protection permanently enabled, requiring valid JEDEC command sequences before any erase or program operation can execute.
Is SST39LF010-55-4C-NHE-T compatible with standard JEDEC x8 Flash interfaces?
Yes, SST39LF010-55-4C-NHE-T conforms fully to JEDEC® standard pinouts and command sets for x8 parallel Flash memories. Its 32-pin PLCC layout matches industry-standard addressing (A0–A16), data (DQ0–DQ7), and control signals (CE#, OE#, WE#), enabling drop-in replacement in existing designs using compatible densities. Command sequences-including byte program, sector erase, chip erase, and software ID read-are JEDEC-approved and interoperable with standard Flash-aware bootloaders and programming tools.
