... PROM DESCRIPTION The X25C02 is a CMOS 2048-bit serial E nally organized as 256 x 8. The X25C02 features a serial interface and software protocol allowing operation on a simple three-wire bus. The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. ...

... the standby power mode. CS LOW enables the X25C02, placing it in the active power mode. It should be noted that after power-up, a HIGH to LOW transition required prior to the start of any operation. Write Protect (WP) When WP is LOW, nonvolatile writes to the X25C02 are disabled, but the part otherwise functions normally ...

... If the clock line is shared with other peripheral devices on the SPI bus, the user can assert the HOLD input to place the X25C02 into a “PAUSE” condition. After releasing HOLD, the X25C02 will resume operation from the point when HOLD was first asserted ...

... CS HIGH. Refer to the read operation sequence illustrated in Figure 1. Write Sequence Prior to any attempt to write data into the X25C02, the “write enable” latch must first be set by issuing the WREN instruction (See Fig. 2 first taken LOW, then the instruction is clocked into the X25C02. After all eight bits of the instruction are transmitted, CS must then be taken HIGH ...

... X25C02 Operational Notes The X25C02 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 high impedance. • The “write enable” latch is reset. ...
