Product details
Overview
SST39VF800A-70-4I-MAQE-T from Microchip Technology is an 8 Mbit (512K x 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 industrial microcontroller boot loaders and firmware update modules.
For engineers reviewing the SST39VF800A-70-4I-MAQE-T datasheet, SST39VF800A-70-4I-MAQE-T pinout, SST39VF800A-70-4I-MAQE-T application, or SST39VF800A-70-4I-MAQE-T equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, sector/block-erase architecture (256 × 2 KWord sectors / 16 × 32 KWord blocks), toggle-bit/data# polling status detection, and industrial temperature range (–40°C to +85°C).
Technical Context
The SST39VF800A-70-4I-MAQE-T implements a JEDEC-compliant x16 asynchronous parallel interface with dedicated CE#, OE#, and WE# control lines, supporting standard microprocessor bus timing. Its SuperFlash® split-gate cell architecture enables fixed erase/program times independent of wear level - 18 ms for sector/block erase and 14 µs per word-program - eliminating software de-rating over lifetime.
It uses AMS = A18 addressing (per Table 1 and Figure 4), supports CFI Query mode via 0x5555/0x98 command sequence, and requires six-byte software command sequences for all erase operations. Hardware protection includes VDD power-up/down detection (<1.5 V inhibit), noise/glitch immunity (<5 ns pulse rejection), and write-inhibit mode via CE#/OE#/WE# logic states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Package | 48-ball WFBGA (4 mm × 6 mm); meets space-constrained PCB layouts in industrial controllers and IoT edge nodes. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, industrial-grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A17 | Address Inputs | A0–A16 used for byte/word addressing; A17 selects upper/lower half of 512K-word array (AMS = A18 per Table 1). |
| DQ0–DQ15 | Data I/O | x16 bidirectional data bus; outputs tri-stated when CE# or OE# high; latched during write cycles. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; must be low with CE# for valid reads. |
| WE# | Write Enable | Active-low write control; initiates command latching and internal program/erase timing on rising edge. |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and memory array; internally generates VPP for programming. |
| VSS | Ground | Two dedicated ground balls (pins E8, H1) reduce noise coupling and improve signal integrity. |
| NC | No Connect | Unbonded pads (e.g., A18 in WFBGA layout per Figure 4); must remain floating per design. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide tunneling injector delivers fixed 14 µs word-program and 18 ms erase times across full lifetime - no software aging compensation needed. |

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-MAQE-T | Commercial temperature grade (0°C to +70°C); identical electrical specs and pinout. | Limited to climate-controlled indoor electronics; not rated for industrial ambient extremes. | Select when cost sensitivity outweighs extended temperature requirements and board-level thermal management is assured. |
| MX29LV800CTTI-70G | 8 Mbit x16, 70 ns, 3.0–3.6 V; uses different command set and lacks CFI support; 48-TSOP package only. | Requires driver rework due to non-JEDEC-compatible erase commands; no WFBGA option limits miniaturization. | Choose only if legacy TSOP socket reuse is mandatory and firmware abstraction layer can accommodate vendor-specific commands. |
Compared with SST39VF800A-70-4C-MAQE-T, the -4I variant adds guaranteed operation down to –40°C - critical for outdoor or factory-floor deployment - while MX29LV800CTTI-70G trades CFI compatibility and WFBGA packaging for lower unit cost in non-space-constrained designs.

FAQ
What is the maximum operating temperature range for the SST39VF800A-70-4I-MAQE-T?
The SST39VF800A-70-4I-MAQE-T is rated for industrial temperature operation from –40°C to +85°C. This specification is guaranteed across the full 2.7–3.6 V supply range and applies to all functional modes - read, program, and erase - as defined in the DS25001A datasheet revision 03/11. The "I" suffix explicitly denotes industrial grade.
Does the SST39VF800A-70-4I-MAQE-T support Common Flash Interface (CFI)?
Yes, the SST39VF800A-70-4I-MAQE-T fully supports CFI per JEDEC JESD68. Entering CFI Query mode requires writing 0x98 to address 0x5555 using the standard software command sequence. CFI data - including geometry, timing parameters, and command set - is accessible at standardized offsets (e.g., 0x10–0x12 for "QRY" string) and enables generic flash driver implementation in RTOS or bootloader environments.
What package type is used for the SST39VF800A-70-4I-MAQE-T?
The SST39VF800A-70-4I-MAQE-T uses a 48-ball WFBGA package measuring 4 mm × 6 mm. This is confirmed in Figures 4 and 5 of the DS25001A datasheet and distinguishes it from TSOP or TFBGA variants. The "MAQE" suffix in the part number explicitly denotes this WFBGA configuration with industrial temperature rating and lead-free finish.
How many erase sectors and blocks does the SST39VF800A-70-4I-MAQE-T have?
The SST39VF800A-70-4I-MAQE-T contains 256 uniform 2 KWord sectors (totaling 512K words) and 16 uniform 32 KWord blocks (also totaling 512K words), as specified in Table 9 of DS25001A. Each sector is 4 KBytes (2 KWords × 2 bytes), and each block is 64 KBytes (32 KWords × 2 bytes), enabling flexible firmware partitioning and partial reprogramming without full chip erase.
What is the typical active current consumption of the SST39VF800A-70-4I-MAQE-T during read operations?
At 14 MHz operation, the SST39VF800A-70-4I-MAQE-T draws a typical active current of 9 mA during read cycles, as stated in the "Low Power Consumption" section of the DS25001A datasheet. This value is measured under standard conditions (VDD = 3.3 V, CL = 100 pF per Table 10) and reflects actual dynamic power draw - not worst-case DC supply current.
