The AT26DF161A is a serial interface Flash memory device designed for use in a wide variety of high-volume consumer-based applications. It has a flexible erase architecture with a minimum erase granularity of 4 Kbytes, making it ideal for data storage. The physical sectoring and the erase block size make it a good choice for a variety of applications.
The AT26DF161A DataFlash provides a 16‑megabit serial interface Flash memory designed for high‑volume consumer and data‑storage applications. It supports SPI modes 0 and 3, operates from a single 2.7 V‑3.6 V supply, and offers low power consumption (5 mA active read, 10 pA deep power‑down).
The device features a flexible erase architecture with 4‑KB, 32‑KB and 64‑KB block sizes, 32 physical sectors of 64 KB each, and individual sector protection with global protect/unprotect commands. It is available in 8‑lead SOIC and 8‑contact MLF packages.
