Product details
Overview
SST39VF010-70-4I-WHE-T from Microchip Technology (formerly Silicon Storage Technology) is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with JEDEC-standard x8 parallel interface, 70 ns read access time, 2.7–3.6 V single-supply operation, and uniform 4 KB sector-erase architecture. It serves as nonvolatile program/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST39VF010-70-4I-WHE-T datasheet, SST39VF010-70-4I-WHE-T pinout, SST39VF010-70-4I-WHE-T application, or SST39VF010-70-4I-WHE-T equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), low standby current (1 µA typical), SuperFlash® endurance (100,000 cycles), and software/hardware data protection compliance with JEDEC command sets.
Technical Context
This device implements SST's proprietary SuperFlash® technology with split-gate cell design and thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional flash. It supports standard microprocessor bus interfacing via CE#, OE#, and WE# control lines with latched address/data inputs.
Operation relies on JEDEC-compliant six-byte software command sequences for sector-erase (30H) and chip-erase (10H), and three-byte sequences for byte-program (A0H). End-of-write detection uses DQ7 Data# Polling and DQ6 Toggle Bit, both valid after the fourth (program) or sixth (erase) WE#/CE# pulse edge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), directly replaces EPROMs and earlier parallel flash in legacy 8-bit bus designs. |
| Read Access Time | 70 ns maximum - enables direct connection to 14 MHz microcontrollers without wait states. |
| Supply Voltage | 2.7–3.6 V - supports battery-backed and low-voltage industrial systems where 3.3 V rails are standard. |
| Endurance | 100,000 program/erase cycles - sufficient for firmware update cycles over 10+ years in deployed equipment. |
| Data Retention | Greater than 100 years - ensures long-term reliability in unpowered storage applications. |
| Standby Current | 1 µA typical - critical for always-on embedded devices with strict power budgets. |
| Sector Size | Uniform 4 KB sectors - simplifies firmware partitioning and OTA update management with predictable erase granularity. |
Pinout & Package
32-lead PLCC (Plastic Leaded Chip Carrier) package, RoHS compliant, with JEDEC-standard x8 parallel memory pinout. Pin functions conform to industry-standard flash memory interface conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A16 provide full 128K-word addressing; A16 is most significant address for SST39VF010. |
| DQ0–DQ7 | Data I/O | Bi-directional 8-bit data bus; outputs tri-stated when CE# or OE# is high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (1 µA) when high. |
| OE# | Output Enable | Active-low output gate; controls data bus visibility during read cycles only. |
| WE# | Write Enable | Active-low control for program/erase command latching and internal timing initiation. |
| VDD | Power Supply | 2.7–3.6 V supply; internal charge pump generates VPP for programming without external high voltage. |
| VSS | Ground | Reference ground for all digital and analog circuitry. |
| NC | No Connection | Pins 12, 17, 20, and 31 are unconnected; must be left floating or tied to ground per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell enables fixed 18 ms sector-erase and 70 ms chip-erase times across full lifetime - eliminates software de-rating. |
| Software Data Protection | JEDEC-compliant 3-byte (program) and 6-byte (erase) command sequences prevent accidental writes during power transitions. |
| Hardware Write Inhibit | Automatic lockout when VDD < 1.5 V, plus noise immunity against <5 ns glitches on WE#/CE#. |
| End-of-Write Detection | DQ7 Data# Polling and DQ6 Toggle Bit allow host CPU to poll status without dedicated interrupt lines or timers. |
| Industrial Temperature Range | Rated −40°C to +85°C - qualified for deployment in factory automation, transportation, and outdoor electronics. |

FAQ
What is the operating temperature range for SST39VF010-70-4I-WHE-T?
The SST39VF010-70-4I-WHE-T is rated for industrial temperature operation from −40°C to +85°C. This specification is confirmed in Table 6 of the official DS25023B datasheet and distinguishes it from commercial-grade variants like SST39VF010-70-4C-WHE-T. The device maintains full functionality-including 70 ns read access and reliable program/erase cycles-across this full range.
Does SST39VF010-70-4I-WHE-T require an external VPP voltage for programming?
No, the SST39VF010-70-4I-WHE-T does not require an external VPP voltage. It integrates an internal charge pump that generates the necessary high voltage for programming and erasing operations using only the 2.7–3.6 V VDD supply. This is explicitly stated in the "Automatic Write Timing" feature section and confirmed in the DC Operating Characteristics table of the DS25023B datasheet.
How many program/erase cycles is SST39VF010-70-4I-WHE-T rated for?
The SST39VF010-70-4I-WHE-T is rated for 100,000 program/erase cycles, with this endurance value specified as typical in the Features section and verified per JEDEC Standard A117 in the Reliability Characteristics table (Table 11) of DS25023B. Data retention exceeds 100 years under normal operating conditions.
What package type is used for SST39VF010-70-4I-WHE-T?
The SST39VF010-70-4I-WHE-T uses a 32-lead PLCC (Plastic Leaded Chip Carrier) package, as documented in the "Packages Available" section and Figure 2 of the DS25023B datasheet. The "WHE-T" suffix denotes this PLCC variant, RoHS compliant, with standard pinout compatible with JEDEC x8 flash memory footprints.
Can SST39VF010-70-4I-WHE-T be used as a direct replacement for SST39LF010-55-4C-WHE-T?
No, SST39VF010-70-4I-WHE-T is not a direct replacement for SST39LF010-55-4C-WHE-T due to key differences: it operates at slower 70 ns (vs. 55 ns), supports lower 2.7 V minimum VDD (vs. 3.0 V), and is rated for industrial temperature (vs. commercial). While pin-compatible and functionally similar, timing and voltage margins must be re-validated in the target system before substitution.
