Product details
Overview
SST39VF010-70-4C-WHE-T from Microchip Technology is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 2.7–3.6 V single-supply write operation, 70 ns read access time, and uniform 4 KB sector-erase architecture. It implements SuperFlash technology for high reliability in embedded firmware storage applications requiring field-upgradable code or configuration data.
For engineers reviewing the SST39VF010-70-4C-WHE-T datasheet, SST39VF010-70-4C-WHE-T pinout, SST39VF010-70-4C-WHE-T application, or SST39VF010-70-4C-WHE-T equivalent, this page delivers verified specifications, JEDEC-compliant x8 interface behavior, industrial-grade temperature support (–40°C to +85°C), and real-world flash endurance and timing validation - all critical for BOM qualification and long-life product design.
Technical Context
The SST39VF010-70-4C-WHE-T uses SST's proprietary split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports standard JEDEC x8 command sets including byte-program, sector-erase (30H), chip-erase (10H), and software product ID (90H).
Write operations require a six-byte software data protection (SDP) sequence for erase and three-byte SDP for program; status detection is implemented via DQ7 Data# Polling and DQ6 Toggle Bit. The device operates in Read, Program, Sector-Erase, Chip-Erase, Standby, and Software ID modes controlled by CE#, OE#, and WE# logic levels.
Key Specifications

|---|---|
| Memory Density | 1 Mbit (128K × 8), providing 131,072 bytes of nonvolatile storage for boot code or parameter tables. |
| Read Access Time | 70 ns max - defines minimum bus cycle duration for reliable CPU or FPGA read access at full speed. |
| Supply Voltage Range | 2.7–3.6 V - enables direct integration into 3.3 V systems without level-shifting or auxiliary regulators. |
| Endurance | 100,000 program/erase cycles (typical) - supports frequent firmware updates over product lifetime. |
| Data Retention | Greater than 100 years - ensures long-term integrity of stored calibration data or security keys. |

| Package | 32-lead TSOP (8 mm × 14 mm) - surface-mount compatible with standard reflow profiles and automated assembly. |
Pinout & Package
Package: 32-lead TSOP (8 mm × 14 mm), RoHS compliant, standard JEDEC x8 pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus (A0–A16) selects one of 131,072 bytes; A12–A16 define sector address during erase. |
| DQ0–DQ7 | Data Input/Output | 8-bit bidirectional data bus; tri-stated when CE# or OE# is high; latched internally during write. |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; high state places device in standby (1 µA typical). |
| OE# | Output Enable | Active-low output gate; controls data bus drive; used with CE# to manage read timing and bus contention. |
| WE# | Write Enable | Active-low control for write cycles; initiates internal program/erase after valid command sequence. |
| VDD | Power Supply | 2.7–3.6 V supply; includes on-chip VPP generation - no external high-voltage generator required. |
| VSS | Ground | Reference ground for all I/O and core logic; decoupling capacitor placement critical for noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT29LV010A-12JC | 1 Mbit, 120 ns access, 3.0–3.6 V only, PLCC-32 package | Lacks industrial temp range; slower read timing limits high-speed MCU interfacing | Select when legacy PLCC footprint is mandatory and 120 ns latency is acceptable. |
| SST39VF010-70-4I-WHE | Identical electrical specs but rated for industrial temp (–40°C to +85°C); same TSOP-32 package | No functional difference; WHE-T suffix denotes tape-and-reel packaging for SMT production | Prefer for volume manufacturing where automated pick-and-place requires reel packaging. |
Compared with AT29LV010A-12JC, SST39VF010-70-4C-WHE-T offers faster 70 ns access and broader 2.7–3.6 V operation; compared with SST39VF010-70-4I-WHE, the -4C suffix confirms commercial temperature grade (0°C to +70°C) and tape-and-reel delivery - ideal for cost-sensitive consumer electronics production.

FAQ
What is the maximum operating frequency supported by SST39VF010-70-4C-WHE-T?
The SST39VF010-70-4C-WHE-T does not specify a maximum clock frequency because it is an asynchronous parallel flash device. Its timing is governed by access times: 70 ns read cycle time (TRC), meaning it supports CPU or FPGA bus interfaces running up to approximately 14 MHz (1/70 ns ≈ 14.3 MHz). Actual system speed depends on controller setup/hold timing margins and board layout.
Does SST39VF010-70-4C-WHE-T support both CE#- and WE#-controlled write operations?
Yes, SST39VF010-70-4C-WHE-T supports both CE#- and WE#-controlled write operations, as confirmed in Figures 7 and 8 of the DS25023A datasheet. The device accepts identical command sequences regardless of which control signal triggers the internal operation - provided minimum pulse widths (40 ns) and setup/hold timing (e.g., TCS, TCH) are met per Table 13.
What is the purpose of the "WHE-T" suffix in SST39VF010-70-4C-WHE-T?
The "WHE-T" suffix in SST39VF010-70-4C-WHE-T indicates a 32-lead TSOP package (WHE) supplied in tape-and-reel format (T) for automated surface-mount assembly. The "-4C" denotes commercial temperature grade (0°C to +70°C) and 70 ns speed grade. This packaging configuration ensures compatibility with high-volume SMT lines and reduces handling damage risk.
How is data protection implemented in SST39VF010-70-4C-WHE-T?
SST39VF010-70-4C-WHE-T implements dual-layer data protection: hardware-level noise/glitch filtering (WE#/CE# pulses <5 ns ignored), VDD power-up/down detection (<1.5 V inhibits writes), and software-level JEDEC-compliant Software Data Protection (SDP). SDP requires validated three-byte sequences for programming and six-byte sequences for erasing - preventing accidental modification during power transients or firmware bugs.
Can SST39VF010-70-4C-WHE-T be used as a direct replacement for SST39LF010-45-4C-WHE-T?
No, SST39VF010-70-4C-WHE-T is not a direct replacement for SST39LF010-45-4C-WHE-T due to key differences: voltage range (2.7–3.6 V vs. 3.0–3.6 V), read access time (70 ns vs. 45 ns), and timing parameters (e.g., TOE = 35 ns vs. 30 ns). While pin-compatible and functionally similar, the VF variant's slower timing and lower VDD minimum may cause timing violations in systems designed for the LF part's tighter specs.
