Brief Description

The PM25LD512C2-DCE-TR is a 512Kbit Serial Peripheral Interface (SPI) Flash memory. It supports single- or dual-output and operates at a clock rate of up to 33 MHz in normal read mode and 100 MHz in fast read mode, making it one of the fastest in the industry. The memory is organized in sectors and blocks, with different sizes depending on the variant: 512 Kbit, 1 Mbit, or 2 Mbit. The PM25LD512C2-DCE-TR has low power consumption, with a standby current of 1uA and typical active read current of 10 mA. It features hardware and software write protection, as well as high product endurance of 200,000 program/erase cycles per single sector.
