... TM Protection DESCRIPTION The X25F047 is a CMOS 4K-bit SerialFlash, internally organized as 512 x 8. The X25F047 features a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple four-wire bus. The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input, allowing any number of devices to share the same bus ...

... CS SO *SOIC Measurement PRINCIPLES OF OPERATION The X25F047 is a 512 x 8 SerialFlash designed to inter- face directly with the synchronous Serial Peripheral Inter- face (SPI) of many popular microcontroller families. The X25F047 contains an 8-bit instruction register accessed via the SI input, with data being clocked in on the rising edge of SCK ...

... Enable” latch must first be set by issuing the PREN instruction (Table 1 and Figure 4 first taken LOW. Then the PREN instruction is clocked into the X25F047. After all eight bits of the instruction are transmitted, CS must then be taken HIGH. If the user continues the program operation without taking CS HIGH after issuing the PREN instruction, the program opera- tion will be ignored ...

BYTE) SI HIGH IMPEDANCE SO Operational Notes The X25F047 powers up in the following state: • The device is in the low power, standby state. • A HIGH to LOW transition required to enter an active state and receive an instruction. • SO pin is at high impedance. • The “Program Enable” latch is reset. ...
