HT24LC256数据手册Holtek中文资料规格书

描述 Description

The HT24LC256 device is a 256K-bit 2-wire serial read/write non-volatile memory device manufactured using a CMOS floating gate process. Its 256K bits of memory are organized into 32K words and each word is 8 bits. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. Up to eight HT24LC256 devices may be connected to the same two-wire bus. The HT24LC256 is guaranteed for 1M erase/write cycles and 40-year data retention.
