The IS25C32A is 32Kbit (4096 x 8) and the IS25C64A is 64Kbit (8192 x 8). The IS25C32A/64A EEPROMs are offered in a wide operating voltage range of 1.8V to 5.5V to be patible with most application voltages. ISSI designed the IS25C32A/64A to be an efficient SPI EEPROM solution. The devices are packaged in 8-pin PDIP, 8-pin SOIC, and 8-pin TSSOP. The functional features of the IS25C32A/64A allow them to be among the most advanced 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 IS25C32A/64A provides for high-speed access, a HOLD pin allows the memories to ignore the interface in a suspended state; later the HOLD pin re-activates munication without reinitializing the serial sequence. A Status Register facilitates a flexible write protection mechanism, and a device-ready bit (RDY). Copyright © 2006 Integrated Silicon Solution, Inc. All rights reserved.
