Product details
Overview
SST39VF010-70-4C-NHE from Microchip Technology is a 1-Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 2.7V–3.6V single-supply write operation, 70 ns read access time, and uniform 4-Kbyte sector erase architecture. It serves as nonvolatile program/data storage in embedded microcontroller systems requiring field-upgradable firmware and configuration data.
For engineers reviewing the SST39VF010-70-4C-NHE datasheet, SST39VF010-70-4C-NHE pinout, SST39VF010-70-4C-NHE application, or SST39VF010-70-4C-NHE equivalent, key selection criteria include voltage range compatibility (2.7V–3.6V), industrial temperature support (−40°C to +85°C), JEDEC-standard x8 flash command set, and SuperFlash® technology's fixed 100,000-cycle endurance.
Technical Context
This device implements Microchip's proprietary SuperFlash® split-gate cell architecture with thick-oxide tunneling injector, delivering fixed erase/program timing independent of cycle count-unlike conventional flash technologies where timing degrades over endurance life. Its control logic supports both CE#- and WE#-controlled byte programming and sector/chip erase via six-byte software data protection (SDP) command sequences.
Operation relies on dual status detection: Data# Polling (DQ7) and Toggle Bit (DQ6), enabling host software to asynchronously monitor write completion without fixed timing delays. The device conforms to JEDEC-standard x8 flash pinouts and operates with CMOS I/O compatibility, supporting latched address/data and high-impedance tri-state outputs during standby.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8) - provides sufficient space for boot code, firmware patches, and configuration tables in resource-constrained MCU systems. |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) at up to ~14 MHz system bus speeds without wait states. |
| Write Voltage Range | 2.7V–3.6V - supports low-voltage operation in battery-powered or mixed-supply industrial designs without external VPP generation. |
| Endurance | 100,000 program/erase cycles - ensures reliable field updates over product lifetime in applications like industrial HMI firmware revision. |
| Data Retention | >100 years - guarantees long-term integrity of calibration data, serial numbers, or security keys stored in unpowered devices. |
| Active Current | 5 mA typical at 14 MHz - minimizes power budget impact during active read operations in always-on edge nodes. |
| Standby Current | 1 µA typical - enables ultra-low-power sleep modes in portable instrumentation and sensor gateways. |
Pinout & Package
The SST39VF010-70-4C-NHE is packaged in a 32-lead PLCC (Plastic Leaded Chip Carrier) with standard JEDEC x8 flash pinout. Pin 1 is NC; pins 6 and 30 are also NC per device variant specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 select 128K bytes; AMS = A16 defines most significant address for sector/block selection during erase. |
| DQ0–DQ7 | Data I/O | Bi-directional 8-bit data bus; outputs 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 read/write operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; must be low with CE# for valid read data. |
| WE# | Write Enable | Active-low write strobe; initiates byte program, sector erase, or chip erase when CE# is also low. |
| VDD | Power Supply | 2.7V–3.6V supply; powers core logic and SuperFlash® array; internal charge pump generates VPP for erase/program. |
| VSS | Ground | Reference return path for all signals and power; requires low-impedance PCB connection to minimize noise coupling. |
| NC | No Connection | Pins 1, 6, and 30 are unconnected; must remain floating or tied to ground per board layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 70 ns read and 14 µs byte program times across full endurance life-eliminates need for software derating or timeout expansion in production firmware. |
| Uniform 4-Kbyte Sectors | Enables granular firmware updates: only modified sectors require erasure, reducing update time and wear on unaffected memory regions. |
| Hardware + Software Data Protection | Prevents accidental writes during power-up/down via VDD monitoring, noise filtering, and mandatory 3-/6-byte SDP command sequences. |
| JEDEC x8 Standard Compliance | Ensures drop-in compatibility with existing 8-bit microcontroller address/data buses and legacy flash drivers without hardware or software modification. |
| Industrial Temperature Range | Rated for −40°C to +85°C operation-qualified for deployment in motor drives, PLC modules, and outdoor IoT gateways without thermal derating. |

FAQ
What is the operating voltage range for SST39VF010-70-4C-NHE?
The SST39VF010-70-4C-NHE operates from 2.7V to 3.6V for both read and write functions. This single-supply range eliminates the need for external VPP generation, simplifying power design in battery-operated or low-voltage industrial systems. The device is specified across commercial (0°C to +70°C) and industrial (−40°C to +85°C) temperature ranges under this voltage window. SST39VF010-70-4C-NHE maintains full functionality-including 70 ns read access and 14 µs byte program-throughout the entire 2.7V–3.6V band.
Does SST39VF010-70-4C-NHE support sector erase, and what is the sector size?
Yes, SST39VF010-70-4C-NHE supports uniform sector erase with each sector sized at 4 Kbytes. The device contains 32 such sectors (128K total), selectable via address lines A12–A0 during the six-byte SDP command sequence. This granularity enables partial firmware updates without erasing the entire array-critical for minimizing downtime in field-deployed equipment. SST39VF010-70-4C-NHE completes sector erase in 18 ms typical, verified via Toggle Bit (DQ6) or Data# Polling (DQ7).
How is write completion detected on SST39VF010-70-4C-NHE?
SST39VF010-70-4C-NHE provides two hardware-supported methods: Data# Polling (DQ7) and Toggle Bit (DQ6). During byte program or erase, DQ7 returns complemented data until completion, then true data; DQ6 toggles between 0 and 1 until completion, then holds steady. Both are valid after the fourth (program) or sixth (erase) WE# pulse. SST39VF010-70-4C-NHE requires no fixed delay loops-software can poll asynchronously, improving system efficiency.
Is SST39VF010-70-4C-NHE pin-compatible with other SST39x series devices?
SST39VF010-70-4C-NHE shares identical 32-lead PLCC pinout and JEDEC x8 command set with SST39VF020-70-4C-NHE and SST39VF040-70-4C-NHE, differing only in density (128K × 8 vs. 256K × 8 vs. 512K × 8). All variants use A16 as the most significant address and support the same SDP command sequences. SST39VF010-70-4C-NHE is not pin-compatible with SST39LF-series (3.0V–3.6V only) due to different VDD tolerance, though package and pin functions match.
What data retention and endurance specifications apply to SST39VF010-70-4C-NHE?
SST39VF010-70-4C-NHE guarantees greater than 100 years of data retention at +25°C and 100,000 program/erase cycles minimum per JEDEC A103 and A117 standards. These values are measured across the full industrial temperature range (−40°C to +85°C) and reflect SuperFlash® technology's inherent reliability-no derating required over lifetime. SST39VF010-70-4C-NHE achieves this with fixed timing: erase/program durations remain constant regardless of accumulated cycles, unlike conventional flash.
