Frequently Asked Questions
How fast can the SST39SF010A-55-4C-WHE respond to a read cycle, and does it require wait states at 8 MHz?
The SST39SF010A-55-4C-WHE has a maximum access time of 55ns, which is fast enough for zero-wait-state reads on most 8 MHz to 16 MHz processor buses. At 8 MHz the bus cycle is 125ns, providing more than 70ns of margin over the 55ns access time, so no wait-state generation logic is needed in typical embedded controller designs.
What is the write/erase endurance of the SST39SF010A-55-4C-WHE, and is it suitable for frequent firmware updates?
The device is rated for 100,000 write/erase cycles per sector, which supports frequent in-field firmware updates in products with daily update schedules for over 270 years of typical use. The 1 Mbit array is organized as 128K x 8, and the sector erase granularity allows targeted updates without rewriting the entire memory array each time.
What package does SST39SF010A-55-4C-WHE use, and how does the TSOP-32 footprint fit in a compact PCB design?
The SST39SF010A-55-4C-WHE is housed in a 32-pin TSOP package with a standard 0.5mm pitch, measuring approximately 20mm x 8mm. This thin small-outline profile allows placement in height-constrained designs and is compatible with automated SMT assembly lines, making it practical for high-volume industrial and consumer boards with limited vertical clearance.
Which embedded applications benefit most from the SST39SF010A-55-4C-WHE's 5V supply and parallel interface?
Legacy industrial controllers, network routers, and BIOS replacement boards that run on a 5V supply and rely on parallel address/data buses gain the most from this device. The 128K x 8 organization and 55ns access time let these systems store up to 128 KB of executable code with direct memory-mapped access, eliminating the serial Flash overhead common in SPI-based alternatives.
