SST25VF080B-80-4I-S2AE

The SST25VF080B-80-4I-S2AE is an 8 Mbit SPI serial flash memory manufactured by SST, a Microchip Technology company. This device utilizes a four-wire, SPI-compatible interface, enabling a low pin-count package that reduces board space and system costs.

Key features include a high-speed clock frequency of up to 80 MHz, enabling efficient data transfer. It operates on a single voltage supply ranging from 2.7V to 3.6V. The memory offers superior reliability with an endurance of 100,000 cycles and data retention exceeding 100 years. Power consumption is also optimized, with an active read current of 10 mA and a standby current of 5 µA.

Flexible erase capabilities include uniform 4 KByte sectors, 32 KByte overlay blocks, and 64 KByte overlay blocks. Programming is enhanced with Auto Address Increment (AAI) for faster chip programming times. End-of-write detection is supported through software polling of the BUSY bit. The device includes a HOLD pin to suspend serial sequences without deselecting the device and write protection features via WP# and software block-protection bits.

Available in various packages including 8-lead SOIC (200 mils and 150 mils), 8-contact WSON (6mm x 5mm), and 8-lead PDIP (300 mils). The SST25VF080B series is designed for applications requiring high-speed serial access to non-volatile memory, offering a balance of performance, reliability, and low power consumption.
