Product details
Overview
SST39VF800A-70-4C-MAQE-T from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with 2.7–3.6 V single-supply operation, 70 ns read access time, JEDEC-standard x16 asynchronous interface, and SuperFlash® split-gate technology enabling 100,000 program/erase cycles and >100 years data retention. It serves as nonvolatile code/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST39VF800A-70-4C-MAQE-T datasheet, SST39VF800A-70-4C-MAQE-T pinout, SST39VF800A-70-4C-MAQE-T application, or SST39VF800A-70-4C-MAQE-T equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, sector/block-erase architecture (2 KWord sectors / 32 KWord blocks), hardware/software write protection, toggle-bit/data# polling status detection, and compatibility with standard x16 parallel memory buses.
Technical Context
The SST39VF800A-70-4C-MAQE-T implements a JEDEC-compliant x16 asynchronous flash interface with address latching on CE# or WE# falling edge and data latching on rising edge. Its SuperFlash® technology uses a split-gate cell with thick-oxide tunneling injector to deliver fixed erase/program timing independent of cycle count.
It supports three software-controlled erase modes-sector (2 KWord), block (32 KWord), and chip-wide-with six-byte command sequences initiated at address 5555H. Write status is verified via DQ6 (Toggle Bit) or DQ7 (Data# Polling), both valid after the sixth WE# pulse for erase operations.
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 | 2.7–3.6 V - supports low-voltage industrial designs without level-shifting circuitry |
| Endurance | 100,000 program/erase cycles - sufficient for firmware update cycles over 10+ years in field-deployed equipment |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Erase Architecture | Uniform 2 KWord sectors (256 total) and 32 KWord blocks (16 total) - enables granular firmware patching without full-chip erasure |
| Write Timing | 14 µs word-program time; 18 ms sector/block-erase time - reduces system downtime during updates |
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 is MSB for 8 Mbit density and must be driven per JEDEC command protocol |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with internal latching; tri-stated when CE# or OE# is high |
| CE# | Chip Enable | Active-low chip select; device enters standby mode (3 µA) when high |
| OE# | Output Enable | Active-low output gate control; required low with CE# for valid read data |
| WE# | Write Enable | Active-low control for program/erase command latching and internal timing initiation |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and charge pump for erase/program operations |
| VSS | Ground | Two dedicated ground balls (pins E8 and H1) reduce noise coupling during high-speed writes |
| NC | No Connection | Unbonded pads (e.g., A18 in some variants); must be left floating or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell architecture delivers fixed 14 µs program and 18 ms erase times across full lifecycle, eliminating software de-rating |
| Software Data Protection (SDP) | JEDEC-compliant 6-byte erase and 3-byte program command sequences prevent accidental writes during power transitions |
| Hardware Write Inhibit | Automatic lockout when VDD < 1.5 V, or if OE# low / CE# high / WE# high - eliminates external reset supervision |
| Common Flash Interface (CFI) | Built-in CFI query mode (entry via 98H at 5555H) provides runtime identification of geometry, timing, and command set |
| Low Standby Current | 3 µA typical - extends battery life in always-on IoT edge nodes with infrequent firmware updates |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-EQE | Same die and timing, but in 48-ball TFBGA (6 mm × 8 mm) package - larger footprint, different ball pitch (0.8 mm vs. 0.5 mm) | Compatible for board-level redesign where thermal dissipation or assembly yield favors TFBGA over WFBGA | Select when existing PCB layout accommodates 6×8 mm TFBGA and requires identical electrical behavior |
| MX29LV800CTTI-70G | 8 Mbit x16 CFI-compliant flash; 70 ns access, but requires 3.0–3.6 V only and lacks SuperFlash®'s fixed timing - erase time increases with cycle count | Acceptable for cost-sensitive consumer applications where 100K-cycle endurance is not mandatory | Choose only if voltage range compatibility and lower endurance are acceptable trade-offs for legacy design continuity |
Compared with SST39VF800A-70-4C-MAQE-T, the TFBGA variant offers identical functionality in a larger package for easier rework, while the MX29LV800CTTI-70G sacrifices SuperFlash®'s cycle-independent timing and wider voltage range for broader distributor availability.

FAQ
What is the exact memory organization of the SST39VF800A-70-4C-MAQE-T?
The SST39VF800A-70-4C-MAQE-T is organized as 512K words × 16 bits, totaling 8 Mbit (1,048,576 bytes). This structure supports byte-wide or word-wide access via its 16-bit DQ bus, with address lines A0–A17 covering the full 512K-word space. The device uses A18 as the most significant address bit during command sequences per JEDEC protocol, confirming its 8 Mbit density.
Does the SST39VF800A-70-4C-MAQE-T support both sector and block erase modes?
Yes, the SST39VF800A-70-4C-MAQE-T supports both sector-erase (2 KWord uniform sectors, 256 total) and block-erase (32 KWord uniform blocks, 16 total) modes. Erase is initiated via JEDEC-compliant six-byte command sequences - 80H/30H for sector and 80H/50H for block - with address latching on the sixth WE# pulse. Both modes complete in 18 ms typical, enabling flexible firmware update strategies.
What write protection mechanisms does the SST39VF800A-70-4C-MAQE-T implement?
The SST39VF800A-70-4C-MAQE-T implements dual-layer protection: hardware-based write inhibit (VDD lockout below 1.5 V, OE#/CE#/WE# state monitoring) and software-based JEDEC-compliant Data Protection (SDP) requiring 3-byte sequences for programming and 6-byte sequences for erasing. These features prevent unintended writes during power-up/down or noise events without external circuitry.
How is end-of-write detection implemented in the SST39VF800A-70-4C-MAQE-T?
The SST39VF800A-70-4C-MAQE-T provides two software-detectable status bits: DQ6 (Toggle Bit), which alternates between 0 and 1 during internal program/erase and stops toggling upon completion; and DQ7 (Data# Polling), which outputs complemented data during write and true data afterward. Both are valid after the sixth WE# pulse for erase operations and enable deterministic host polling without fixed timeouts.
Is the SST39VF800A-70-4C-MAQE-T compatible with standard x16 parallel memory buses?
Yes, the SST39VF800A-70-4C-MAQE-T conforms fully to JEDEC standard pinouts and command sets for x16 asynchronous flash memories. Its CE#, OE#, and WE# controls, latched address/data timing, and tri-state outputs ensure drop-in compatibility with legacy microcontroller and FPGA memory controllers designed for JEDEC-compliant parallel flash devices.
