Product details
Overview
SST39VF800A-70-4I-MAQE from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 2.7–3.6 V with 70 ns read access time, 14 µs word-program time, and uniform 2 KWord sector / 32 KWord block erase architecture. It serves as nonvolatile program/data storage in industrial embedded controllers requiring field-upgradable firmware.
For engineers reviewing the SST39VF800A-70-4I-MAQE datasheet, SST39VF800A-70-4I-MAQE pinout, SST39VF800A-70-4I-MAQE application, or SST39VF800A-70-4I-MAQE equivalent, key selection criteria include its 2.7 V minimum VDD operation, JEDEC-standard x16 asynchronous interface, 256-sector/16-block organization, hardware/software data protection, and compatibility with CFI query and software ID identification protocols.
Technical Context
This device implements a split-gate SuperFlash cell with thick-oxide tunneling injector for enhanced endurance (100,000 cycles) and >100-year data retention. Its command-set architecture requires six-byte sequences for sector/block/chip erase and three-byte sequences for word-program, all initiated via standard microprocessor write timing with CE# and WE# control.
Write status detection uses DQ7 (Data# Polling) and DQ6 (Toggle Bit), both valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse. The device supports Common Flash Interface (CFI) mode entry via 5555H/AAH–2AAAH/55H–5555H/98H sequence and exits via F0H or 5555H/AAH–2AAAH/55H–5555H/F0H.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16), providing 1 MB of nonvolatile storage for firmware or configuration data |
| Read Access Time | 70 ns - determines maximum sustained read throughput in x16 bus systems |
| Word-Program Time | 14 µs typical - enables fast in-system updates without extended system stall |
| Erase Architecture | 256 uniform 2 KWord sectors + 16 uniform 32 KWord blocks - supports granular firmware patching and full-image reprogramming |
| Supply Voltage Range | 2.7–3.6 V - enables direct integration into 3.3 V industrial power domains with margin for brown-out resilience |
| Endurance & Retention | 100,000 program/erase cycles / >100 years data retention - validated for long-life embedded deployments |
| Interface Standard | JEDEC-standard x16 asynchronous parallel interface - ensures drop-in compatibility with legacy 16-bit microcontroller buses |
Pinout & Package
Package: 48-ball TFBGA (6 mm × 8 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | A0–A17 used for SST39VF800A (512K×16); A18 is most-significant address for block selection during Block-Erase |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; outputs tri-stated when CE# or OE# high; latched on write |
| 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 all write operations (program/erase); initiates command latching on rising/falling edges |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and memory array; internal VPP generation eliminates external high-voltage requirement |
| VSS | Ground | Two dedicated ground pins (pins 23 and 48 in TFBGA) reduce noise coupling and improve signal integrity |
| NC | No Connect | Unbonded pins (e.g., A17 in 200A variant, but used in 400A/800A); must be left floating or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector delivers 100k-cycle endurance and >100-year retention without performance degradation over lifetime |
| Uniform Erase Architecture | 256 × 2 KWord sectors and 16 × 32 KWord blocks enable precise firmware partitioning and incremental field updates |
| Hardware + Software Data Protection | Glitch filtering (<5 ns), VDD lockout (<1.5 V), and JEDEC-compliant 3-/6-byte command sequences prevent accidental writes during power transitions |
| CFI & Software ID Support | Standard CFI query (98H) and product ID (90H) commands allow runtime identification and vendor-agnostic flash management firmware |
| Low-Power Operation | 3 µA standby current and 9 mA active current at 14 MHz support battery-backed or energy-constrained industrial applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the memory organization of the SST39VF800A-70-4I-MAQE?
The SST39VF800A-70-4I-MAQE is organized as 512K words × 16 bits (8 Mbit total), delivering 1 MB of addressable nonvolatile storage. This x16 configuration interfaces directly with 16-bit microcontroller buses, and its address space spans A0–A17 for word addressing, with A18 used during Block-Erase operations. The SST39VF800A-70-4I-MAQE implements 256 uniform 2 KWord sectors and 16 uniform 32 KWord blocks for flexible erase granularity.
Does the SST39VF800A-70-4I-MAQE support CFI and software identification?
Yes, the SST39VF800A-70-4I-MAQE fully supports Common Flash Interface (CFI) mode via the 5555H/AAH–2AAAH/55H–5555H/98H command sequence, enabling runtime interrogation of device geometry and timing parameters. It also supports Software Product Identification using 5555H/AAH–2AAAH/55H–5555H/90H to read manufacturer ID (00BFH) and device ID (2781H), allowing firmware to distinguish SST39VF800A-70-4I-MAQE from other variants in mixed-socket designs.
What voltage range does the SST39VF800A-70-4I-MAQE require for program/erase operations?
The SST39VF800A-70-4I-MAQE requires a single supply voltage of 2.7–3.6 V for all operations - including read, program, and erase - eliminating need for external VPP programming voltage. Internal charge pump circuitry generates required high-voltage levels for Fowler-Nordheim tunneling, simplifying power design. This 2.7 V minimum enables reliable operation in brown-out conditions common in industrial 3.3 V systems.
How is write completion detected on the SST39VF800A-70-4I-MAQE?
Write completion on the SST39VF800A-70-4I-MAQE is detected using two hardware-supported methods: Data# Polling (DQ7) and Toggle Bit (DQ6). During Program, DQ7 returns complemented data until completion, then true data; during Erase, DQ7 reads '0' then '1'. DQ6 toggles between 0 and 1 during operation and stabilizes upon completion. Both signals are valid after the rising edge of the fourth (Program) or sixth (Erase) WE# pulse.
What package type is used for the SST39VF800A-70-4I-MAQE?
The SST39VF800A-70-4I-MAQE is packaged in a 48-ball Thin Fine-Pitch Ball Grid Array (TFBGA) measuring 6 mm × 8 mm, with RoHS-compliant lead-free solder balls. This package supports high-density PCB layouts and offers superior thermal and electrical performance compared to TSOP alternatives. Pin assignments follow JEDEC-standard x16 flash layout, with dedicated VSS pins (balls E6 and H1) and NC locations consistent with SST39VF800A-70-4I-MAQE's 512K×16 architecture.
