Overview
SST39LF801C-55-4C-MAQE-T from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with 55 ns read access time, operating at 3.0–3.6 V supply, and featuring bottom-boot block protection for firmware storage in embedded controllers. It supports sector/block/chip erase, hardware write protection via WP#, and Ready/Busy# status signaling.
For engineers reviewing the SST39LF801C-55-4C-MAQE-T datasheet, SST39LF801C-55-4C-MAQE-T pinout, SST39LF801C-55-4C-MAQE-T application, or SST39LF801C-55-4C-MAQE-T equivalent, key selection considerations include boot-block architecture (bottom 8 KWord), 48-ball WFBGA (4 mm × 6 mm) package, JEDEC-compliant x16 interface, and SuperFlash® technology enabling fixed 7 µs word-program time and 100,000-cycle endurance.
Technical Context
This device implements a split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, delivering stable erase/program timing independent of cycle count-unlike conventional flash. It uses standard microprocessor bus timing with CE#/OE#/WE# control and supports JEDEC-standard command sets including CFI Query and Software ID entry.
It integrates hardware block protection (bottom 8 KWord boot sector), Erase-Suspend/Resume capability, Auto Low Power mode (3 µA standby), and dual status detection (DQ6 toggle bit + DQ7 data polling) for robust system-level firmware update management in resource-constrained environments.
