IS25C64A中文资料矽成半导体数据手册PDF规格书

DESCRIPTION

The IS25C32A and IS25C64A are electrically erasable PROM devices that use the Serial Peripheral Interface (SPI) for communications. 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 compatible 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.
