25P40VP datasheet

Description

The 25P40VP is a 4 Mbit (512K x 8) Serial Flash Memory, with advanced write protection mechanisms, accessed by a high speed SPI-compatible bus. The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction.

The memory is organized as 8 sectors, each containing 256 pages. Each page is 256 bytes wide.
Thus, the whole memory can be viewed as consisting of 2048 pages, or 524,288 bytes

25L1005MC datasheet pdf

Description

MX25L1005 is a CMOS 1,048,576 bit serial Flash memory, which is configured as 131,072 x 8 internally. The feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). SPI access to the device is enabled by CS# input.

To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read command can be issued to detect completion status of a program or erase operation via WIP bit.
