DESCRIPTION
The M25P10 is an 1 Mbit Paged Flash Memory
fabricated with STMicroelectronics High
Endurance CMOS technology. The memory is
accessed by a simple SPI bus compatible serial
interface. The bus signals are a serial clock input
(C), a serial data input (D) and a serial data output
(Q).
The device connected to the bus is selected when
the chip select input (S) goes low. Data is clocked
in during the low to high transition of clock C, data
