Frequently Asked Questions
How fast can SST39SF010-70-4C-PH be read and what bus width does it use?
The SST39SF010-70-4C-PH has a 70 ns access time on its 8-bit parallel interface, delivering byte-wide data over a 17-bit address bus and supporting direct memory-mapped code execution from a 5 V microprocessor or microcontroller bus without additional buffering.
What is the sector erase time for SST39SF010-70-4C-PH and how is the memory organized?
Sector erase completes in 18 ms per 4 KB uniform sector, and the 128 KB total array is divided into 32 such sectors, giving designers fine-grained erase granularity for in-system firmware updates without disturbing adjacent code regions.
Is SST39SF010-70-4C-PH a suitable drop-in replacement for legacy BIOS Flash in older embedded boards?
Yes, the SST39SF010-70-4C-PH uses a 32-pin PDIP package with a standard 5 V supply and parallel interface, so it is pin- and electrically compatible with many older 1 Mbit Flash devices used in legacy PC BIOS, industrial HMI, and embedded control boards from the same era.
What endurance and data retention specs should engineers verify before selecting SST39SF010-70-4C-PH for a write-intensive application?
SuperFlash technology in the SST39SF010-70-4C-PH is rated for at least 100,000 erase/write cycles per sector and 100-year data retention under normal storage conditions, which is sufficient for firmware update scenarios but may require wear-leveling strategies if sector erase cycles are frequent.
