Part Overview
Description
The RENESAS AT25DF256 is a 256-Kbit, 1.65 V minimum SPI serial flash memory with dual-read support. It is compatible with SPI modes 0 and 3 and supports a maximum operating frequency of 104 MHz. The AT25DF256 features a flexible, optimized erase architecture for code and data storage applications, including small (256-byte) page erase, uniform 4-kByte block erase, uniform 32-kByte block erase, and full chip erase. It also has hardware-controlled locking of protected sectors through the WP pin and a 128-byte, one-time programmable (OTP) security register.
