Product details
Overview
SST39VF800A-70-4C-M1QE from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with x16 asynchronous interface, 2.7–3.6V single-supply operation, 70 ns read access time, and JEDEC-standard pinout. It delivers uniform 2 KWord sector and 32 KWord block erase, 14 µs word-program time, and >100 years data retention for embedded firmware storage in industrial controllers and legacy system upgrades.
For engineers reviewing the SST39VF800A-70-4C-M1QE datasheet, SST39VF800A-70-4C-M1QE pinout, SST39VF800A-70-4C-M1QE application, or SST39VF800A-70-4C-M1QE equivalent, this page provides verified package mapping (48-ball WFBGA), confirmed SuperFlash architecture advantages, JEDEC-compliant command set support, and validated alternative part selection guidance for drop-in replacement scenarios in space-constrained designs.
Technical Context
The SST39VF800A-70-4C-M1QE implements SST's proprietary SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program timing independent of cycle count. Its 512K × 16 organization uses A0–A18 address lines (AMS = A18), supports CFI Query mode via 5555H/98H command, and requires six-byte software command sequences for sector/block/chip erase operations.
It features dual end-of-write detection (DQ6 Toggle Bit and DQ7 Data# Polling), hardware noise/glitch protection (<5 ns pulse rejection), VDD power-up/down write inhibition, and JEDEC-standard x16 pinout compatibility-ensuring interoperability with existing 16-bit memory bus interfaces without redesign.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16), providing 1 MB of nonvolatile storage for boot code or configuration data |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in systems with ≤14 MHz bus timing budgets |
| Supply Voltage | 2.7–3.6V - supports wide-input industrial power rails and battery-backed operation without level-shifting |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in deployed equipment |
| Data Retention | >100 years - guarantees long-term reliability in unpowered storage applications like calibration tables |
| Word-Program Time | 14 µs typical - reduces firmware update latency and minimizes host CPU wait states during writes |
| Erase Granularity | 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - enables selective reprogramming without full-chip erasure |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | A0–A17 used for 512K × 16 addressing; A18 (AMS) selects top-level block/sector during erase commands |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during write; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 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; initiates internal timing on rising edge per JEDEC command sequence |
| VDD | Power Supply | 2.7–3.6V supply; powers all logic and SuperFlash tunneling circuitry |
| VSS | Ground | Two dedicated ground balls (pins E8, H1) reduce noise coupling in high-speed reads |
| NC | No Connection | Unbonded pads (e.g., A17 in WFBGA layout for 800A variant) - must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash split-gate cell | Enables fixed 14 µs program and 18 ms sector-erase times across full lifetime - eliminates software de-rating for aging devices |
| JEDEC-standard x16 interface | Direct drop-in replacement for legacy 16-bit parallel flash sockets without PCB or driver changes |
| Software Data Protection (SDP) | Three-byte unlock sequence required before programming; six-byte sequence for erase - prevents accidental corruption during power transients |
| CFI Query support | Enables automatic detection of density, timing, and command set by bootloader - simplifies multi-part BOM management |
| Uniform 4 KB sectors | 256 sectors total - allows fine-grained firmware partitioning (e.g., separate bootloader, app, config regions) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-EKE | Same die, 48-ball TFBGA (6 mm × 8 mm) package - larger footprint, different ball map, no A18 connection in pinout | Requires PCB redesign; suitable for new designs prioritizing assembly yield over size | Select when board layout allows larger BGA and thermal dissipation requirements exceed WFBGA limits |
| MX29LV800CTTC-70G | 8 Mbit x16 flash with 70 ns access, but uses standard AMD/Fujitsu command set (not SST-specific); 3.0–3.6V only | Not software-compatible - requires bootloader modification for erase/write sequences | Choose only if migrating from legacy AMD-family systems and SST command set dependency is absent |
Compared with SST39VF800A-70-4C-M1QE, the TFBGA variant offers higher thermal mass but demands layout revision, while the MX29LV800CTTC-70G sacrifices command compatibility for broader ecosystem support - making the M1QE optimal for drop-in replacements where firmware and footprint must remain unchanged.

FAQ
What is the exact memory organization of the SST39VF800A-70-4C-M1QE?
The SST39VF800A-70-4C-M1QE is organized as 512K words × 16 bits (8 Mbit total), with address lines A0–A17 used for word selection and A18 (AMS) serving as the most significant address bit for sector/block addressing during erase operations. This structure supports direct 16-bit bus interfacing without data multiplexing.
Does the SST39VF800A-70-4C-M1QE require an external VPP voltage for programming?
No, the SST39VF800A-70-4C-M1QE does not require an external VPP voltage. It generates all necessary high-voltage programming signals internally using its on-chip charge pump, operating solely from the 2.7–3.6V VDD supply - simplifying power design and eliminating VPP routing on the PCB.
How many erase sectors does the SST39VF800A-70-4C-M1QE have, and what is their size?
The SST39VF800A-70-4C-M1QE contains 256 uniform sectors, each sized at 2 KWords (4 KB). This granularity enables precise firmware updates - for example, modifying only the application partition while preserving bootloader and calibration data in adjacent sectors.
Is the SST39VF800A-70-4C-M1QE compatible with standard JEDEC x16 flash sockets?
Yes, the SST39VF800A-70-4C-M1QE conforms fully to JEDEC standard pinouts and command sets for x16 parallel flash memory. Its 48-ball WFBGA footprint maps directly to JEDEC-defined signal assignments, allowing mechanical and electrical compatibility with existing socketed or soldered x16 flash implementations.
What end-of-write detection methods does the SST39VF800A-70-4C-M1QE support?
The SST39VF800A-70-4C-M1QE supports two hardware-supported end-of-write detection methods: Data# Polling (DQ7 toggles until completion, then returns true data) and Toggle Bit (DQ6 alternates logic states during operation and stabilizes upon completion). Both are accessible via standard read cycles without additional hardware.
