Product details
Overview
SST39WF800B-70-4I-C2QE from Microchip Technology is a 8 Mbit (512K × 16) Multi-Purpose Flash memory IC using SuperFlash technology, designed for embedded program/data storage in low-voltage systems. It operates at 1.65–1.95 V, delivers 70 ns read access time, supports sector/block/chip erase, and features hardware/software data protection. It is used in industrial controllers requiring field-upgradable firmware with high reliability.
For engineers reviewing the SST39WF800B-70-4I-C2QE datasheet, SST39WF800B-70-4I-C2QE pinout, SST39WF800B-70-4I-C2QE application, or SST39WF800B-70-4I-C2QE equivalent, key selection criteria include its 1.65–1.95 V single-supply operation, JEDEC-standard x16 asynchronous interface, 100,000-cycle endurance, 100-year data retention, and 48-ball WFBGA (4 mm × 6 mm) packaging.
Technical Context
The SST39WF800B-70-4I-C2QE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command-set follows JEDEC-standard x16 flash protocols, including Software Data Protection (SDP) with three-byte program and six-byte erase sequences.
It uses dual status detection-Data# Polling (DQ7) and Toggle Bit (DQ6)-for end-of-write verification, and supports CFI Query mode for automatic device identification. The device requires no external VPP and generates internal programming voltage, simplifying system power design.

FAQ
What is the operating voltage range for the SST39WF800B-70-4I-C2QE?
The SST39WF800B-70-4I-C2QE operates from 1.65 V to 1.95 V for both read and write functions. This single-supply range eliminates the need for external VPP generation or level shifters, making it ideal for modern low-power embedded systems. The device is specified across the full industrial temperature range (-40°C to +85°C) at this voltage window, and all DC and AC parameters-including 70 ns read access and 28 µs word-program-are guaranteed within these limits. SST39WF800B-70-4I-C2QE does not support 3.3 V or 5 V operation.
Does the SST39WF800B-70-4I-C2QE support JEDEC-standard commands and pinout?
Yes, the SST39WF800B-70-4I-C2QE conforms fully to JEDEC standard pin assignments and command sets for x16 asynchronous flash memories. Its pinout matches industry-standard 48-ball WFBGA layouts, and its software command sequences-including Word-Program, Sector-Erase, Block-Erase, and Chip-Erase-follow JEDEC JESD21-C guidelines. It also supports Common Flash Interface (CFI) Query mode for automatic identification. SST39WF800B-70-4I-C2QE is designed as a pin- and command-compatible upgrade path for legacy x16 NOR flash in existing designs.
How does the SST39WF800B-70-4I-C2QE protect against inadvertent writes?
The SST39WF800B-70-4I-C2QE implements dual-layer protection: hardware-level noise/glitch filtering (rejects WE#/CE# pulses <5 ns), VDD power-up/down detection (inhibits writes below 1.0 V), and Write Inhibit Mode (activated by OE# low, CE# high, or WE# high); plus software-level JEDEC-approved Software Data Protection (SDP) requiring validated three-byte (program) or six-byte (erase) command sequences. SST39WF800B-70-4I-C2QE ships with SDP permanently enabled, ensuring robustness during power cycling or EMI events.
What package type is used for the SST39WF800B-70-4I-C2QE?
The SST39WF800B-70-4I-C2QE is packaged in a 48-ball WFBGA (Wafer-Level Fine-Pitch Ball Grid Array) measuring 4 mm × 6 mm, with 0.5 mm ball pitch. This micro-package supports high-density PCB layouts and complies with RoHS and lead-free assembly standards. Pin assignments match Figures 2 and 3 in DS25031A, and the package includes two VSS balls and dedicated NC positions consistent with the WFBGA variant-not TFBGA or XFLGA variants. SST39WF800B-70-4I-C2QE's mechanical footprint and thermal profile are optimized for reflow soldering per IPC-J-STD-020.
What are the endurance and data retention specifications for the SST39WF800B-70-4I-C2QE?
The SST39WF800B-70-4I-C2QE is rated for a minimum of 10,000 erase/write cycles per JEDEC A117 (with typical performance at 100,000 cycles), and guarantees greater than 100 years of data retention at 25°C per JEDEC A103. These values are measured across the full industrial temperature range (-40°C to +85°C) and apply to all sectors and blocks. Unlike conventional NOR flash, SuperFlash technology maintains fixed erase/program times across the entire endurance lifetime, eliminating the need for software de-rating. SST39WF800B-70-4I-C2QE's reliability metrics are validated under accelerated stress testing and documented in DS25031A Table 13.
