The IS25C01 is 1Kbit (128 x 8). The IS25C01 EEPROM is offered in a wide operating voltage range of 1.8V to 5.5V to be compatible with most application voltages. ISSI designed the IS25C01 to be an efficient SPI EEPROM solution. The device is packaged in 8-pin PDIP, 8-pin SOIC, and 8-pin TSSOP. The functional features of the IS25C01 allow it to be among the most versatile serial non-volatile memories available. Each device has a Chip-Select (CS) pin, and a 3-wire interface of Serial Data In (SI), Serial Data Out (SO), and Serial Clock (SCK). While the 3-wire interface of the IS25C01 provides for high-speed access, a HOLD pin allows the memor...
