Product details
Overview
SST39WF800A-90-4C-B3KE-T from Silicon Storage Technology is an 8 Mbit (512K × 16) single-supply Multi-Purpose Flash memory IC with SuperFlash technology, operating at 1.65–1.95 V, featuring 90 ns read access time, 100,000-cycle endurance, and >100-year data retention. It supports sector-, block-, and chip-erase modes and is used in embedded firmware storage for industrial controllers, network boot loaders, and FPGA configuration memory.
For engineers reviewing the SST39WF800A-90-4C-B3KE-T datasheet, SST39WF800A-90-4C-B3KE-T pinout, SST39WF800A-90-4C-B3KE-T application, or SST39WF800A-90-4C-B3KE-T equivalent, key selection criteria include its 1.8 V core voltage compatibility, uniform 2 KWord sector architecture, JEDEC-standard x16 asynchronous interface, Toggle Bit/Data# Polling write completion detection, and 48-ball WFBGA (5 mm × 6 mm) packaging for space-constrained PCBs.
Technical Context
The SST39WF800A-90-4C-B3KE-T implements a split-gate SuperFlash cell with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional flash-and eliminating software de-rating over lifetime. Its command-set architecture follows JEDEC standard pinouts and uses six-byte sequences for sector/block/chip erase, with internal VPP generation removing external high-voltage requirements.
Operation relies on dual control signals (CE# and WE#) for latching address/data on falling/rising edges respectively, supporting both CE#- and WE#-controlled programming and erase. Write status is verified via DQ6 (Toggle Bit) and DQ7 (Data# Polling), with detection enabled after the fourth (program) or sixth (erase) WE#/CE# pulse-ensuring deterministic timing for real-time system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16), providing 1 MB of nonvolatile storage for firmware images or configuration data |
| Read Access Time | 90 ns max - enables direct execution (XIP) from flash in low-latency microcontroller systems |
| Supply Voltage | 1.65–1.95 V - compatible with 1.8 V I/O domains without level shifting in modern SoC interfaces |
| Endurance | 100,000 program/erase cycles - supports field-updatable firmware with multi-year service life |
| Data Retention | >100 years at 25°C - ensures long-term reliability in unpowered storage applications |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - balances update flexibility with wear-leveling efficiency |
| Write Timing | 28 µs typical word-program time; 36 ms typical sector/block-erase - reduces firmware update duration vs. legacy NOR flash |
Pinout & Package
Package: 48-ball WFBGA (5 mm × 6 mm), RoHS-compliant, lead-free, surface-mountable with 0.5 mm ball pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | A0–A17 select 512K words; A18 (AMS) selects upper/lower half for sector/block addressing |
| DQ0–DQ15 | Data I/O | x16 bidirectional bus; tri-stated when CE# or OE# is high; latched during write on rising edge of CE#/WE# |
| CE# | Chip Enable | Active-low device select; must be low for read/write; high-Z output and standby current (5 µA) when asserted high |
| OE# | Output Enable | Active-low output gate; controls data bus drive; no effect on internal operations when high |
| WE# | Write Enable | Controls latching of address/data and initiates internal program/erase; falling edge latches address, rising edge triggers operation |
| VDD | Power Supply | 1.65–1.95 V core supply; powers all logic and SuperFlash array; internal charge pump generates programming voltage |
| VSS | Ground | Reference for all I/O and core circuitry; two dedicated VSS balls ensure low-noise return path |
| NC | No Connection | Unbonded pins (e.g., A9 in TFBGA variant); must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide injector delivers fixed 36 ms erase time across full lifecycle-no software adaptation needed |
| Hardware + Software Data Protection | Glitch immunity (<5 ns pulses rejected), VDD power-on detection, and JEDEC-standard 3-/6-byte command lockout prevent accidental writes |
| Common Flash Interface (CFI) | Embedded CFI query table (at 10H–34H) enables automatic driver detection and vendor-agnostic firmware initialization |
| Write Completion Detection | DQ6 Toggle Bit and DQ7 Data# Polling provide deterministic, non-blocking status feedback without polling overhead |
| JEDEC x16 Pinout Compliance | Direct drop-in replacement for industry-standard 8 Mbit x16 NOR flash in existing sockets and PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-90-4C-B3KE-T | 3.0 V supply (2.7–3.6 V); identical density, timing, and command set but incompatible voltage domain | Requires separate 3.3 V rail; unsuitable for 1.8 V-only systems; higher active current (15 mA vs. 5 mA) | Select only if legacy 3.3 V design mandates voltage compatibility-no PCB change needed but power delivery must be revised. |
| MX29LV800CTTI-90G | 3.0 V operation; 8 Mbit x16; 90 ns access; lacks SuperFlash fixed-timing; endurance rated at 100,000 cycles but erase time increases with cycling | Compatible pinout but requires firmware adaptation for variable erase timing; no CFI support | Use where cost is primary constraint and lifetime timing predictability is not required; verify system-level wear leveling. |

FAQ
What is the operating voltage range for the SST39WF800A-90-4C-B3KE-T?
The SST39WF800A-90-4C-B3KE-T operates exclusively within a 1.65 V to 1.95 V supply range, optimized for 1.8 V systems. Operation outside this window-such as at 3.3 V-is not supported and may cause permanent damage. This narrow range enables lower power consumption (5 µA standby) and tighter timing margins compared to wider-voltage flash devices.
Does the SST39WF800A-90-4C-B3KE-T support JEDEC-standard commands and pinouts?
Yes, the SST39WF800A-90-4C-B3KE-T fully complies with JEDEC Standard JESD21-C for x16 flash pin assignments and command sets-including sector/block/chip erase, word-program, and software ID entry. Its pinout matches industry-standard 48-ball WFBGA packages, enabling drop-in replacement in validated designs without layout changes.
How does the SST39WF800A-90-4C-B3KE-T detect completion of program or erase operations?
The SST39WF800A-90-4C-B3KE-T provides two hardware-supported methods: DQ6 Toggle Bit (alternating 0/1 during operation, stops when complete) and DQ7 Data# Polling (complement of target data during write, returns true value upon completion). Both are valid after the fourth WE#/CE# pulse for programming and sixth pulse for erasing-enabling efficient, non-blocking firmware routines.
What package type is used for the SST39WF800A-90-4C-B3KE-T?
The SST39WF800A-90-4C-B3KE-T is packaged in a 48-ball WFBGA (5 mm × 6 mm) with 0.5 mm ball pitch, RoHS-compliant and lead-free. This micro-package supports high-density PCB layouts and meets IPC/JEDEC standards for reflow soldering at 260°C for 10 seconds-verified for industrial thermal cycling reliability.
Is the SST39WF800A-90-4C-B3KE-T suitable for automotive applications?
No-the SST39WF800A-90-4C-B3KE-T is specified for commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges only. It does not meet AEC-Q100 qualification requirements for automotive use, lacks extended temperature screening, and has no automotive-grade reliability reporting. For automotive applications, consult Microchip's AEC-Q100-qualified flash portfolio.
