Product details
Overview
SST39WF800B-70-4C-C2QE from Microchip Technology is an 8 Mbit (512K × 16) Multi-Purpose Flash memory IC using SuperFlash technology, operating at 1.65–1.95 V, with 70 ns read access time, 100,000-cycle endurance, and >100-year data retention. It serves as nonvolatile program/data storage in embedded controllers requiring low-voltage, sector/block-erasable flash.
For engineers reviewing the SST39WF800B-70-4C-C2QE datasheet, SST39WF800B-70-4C-C2QE pinout, SST39WF800B-70-4C-C2QE application, or SST39WF800B-70-4C-C2QE equivalent, this page delivers verified pin functions, JEDEC-compliant x16 interface timing, SuperFlash energy efficiency metrics, and validated alternatives for industrial firmware storage upgrades.
Technical Context
The SST39WF800B-70-4C-C2QE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed 28 µs word-program and 36 ms sector/block-erase times independent of cycle count. Its command set conforms to JEDEC-standard x16 flash pinouts and software data protection (SDP) sequences.
It supports three erase granularities-2 KWord sectors, 32 KWord blocks, and full-chip erase-with Toggle Bit (DQ6) and Data# Polling (DQ7) for asynchronous operation completion detection. The device uses internal VPP generation and requires no external high-voltage supply for programming or erasing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit SPI NOR (quad I/O), 3V supply, 8-pin SOIC; serial interface vs. parallel x16. | Requires MCU SPI peripheral and driver stack; unsuitable for legacy parallel-bus boot ROM designs. | Select only if board redesign permits serial interface migration and lower pin count is prioritized. |
| Macronix MX29LV800CTTI-70G | 8 Mbit x16 parallel NOR, 3V supply, 48-TSOP; higher VDD (2.7–3.6 V), slower 70 ns access but same JEDEC pinout. | Not voltage-compatible with 1.8 V SoCs; requires level-shifting or power rail change. | Consider only for 3V systems needing identical footprint and command compatibility without voltage scaling. |
Compared with SST39WF800B-70-4C-C2QE, the Winbond alternative trades parallel bandwidth for integration simplicity, while the Macronix part preserves interface compatibility at the cost of incompatible supply voltage - making SST39WF800B-70-4C-C2QE uniquely suited for 1.8 V embedded systems demanding JEDEC x16 performance and SuperFlash reliability.

FAQ
What is the operating voltage range for the SST39WF800B-70-4C-C2QE?
The SST39WF800B-70-4C-C2QE operates from 1.65 V to 1.95 V for both read and write operations. This single-supply range eliminates the need for external VPP generation and aligns directly with 1.8 V I/O domains of modern microcontrollers and SoCs. Operation outside this range may cause data corruption or failure to execute commands, and the device inhibits writes below 1.0 V via internal power-on reset circuitry.
Does the SST39WF800B-70-4C-C2QE support sector-level erase?
Yes, the SST39WF800B-70-4C-C2QE supports uniform 2 KWord sector-erase using a six-byte command sequence ending with 30H. It contains 256 such sectors, allowing fine-grained firmware updates without disturbing adjacent code or configuration data. Sector-erase completes in 36 ms (typical), and completion is confirmed via Toggle Bit (DQ6) or Data# Polling (DQ7).
What package type is used for the SST39WF800B-70-4C-C2QE?
The SST39WF800B-70-4C-C2QE is packaged in a 48-ball WFBGA (4 mm × 6 mm), also referenced as Micro-Package. This package features a 0.5 mm ball pitch, RoHS compliance, and is qualified for reflow soldering at 260°C for 10 seconds. Pin assignments match JEDEC-standard x16 flash layouts, enabling direct PCB footprint reuse across compatible devices.
How does the SST39WF800B-70-4C-C2QE detect end-of-write operations?
The SST39WF800B-70-4C-C2QE provides two hardware-supported methods: Data# Polling on DQ7 (returns complemented data until completion, then true data) and Toggle Bit on DQ6 (toggles between 0 and 1 during operation, then stabilizes). Both are valid after the fourth WE# pulse for programming and sixth WE# pulse for erase, enabling efficient polling without busy-wait overhead.
Is the SST39WF800B-70-4C-C2QE compatible with JEDEC-standard flash command sets?
Yes, the SST39WF800B-70-4C-C2QE fully conforms to JEDEC Standard JESD21-C for x16 flash pinouts and command definitions. It supports standard commands including Word-Program (A0H), Sector-Erase (30H), Block-Erase (50H), Chip-Erase (10H), and Software ID Read (90H), ensuring interoperability with existing flash controllers and bootloader firmware stacks.
