4V~5.
5V Low power consumption – Operation: 5mA max.
– Standby: 5µA max.
Internal organization – 1K (HT24LC01):128×8 – 2K (HT24LC02): 256×8 2-wire serial interface Write cycle time: 5ms max.
Automatic erase-before-write operation • • • • • • • • • Partial page write allowed 8-byte Page write modes Write operation with built-in timer Hardware controlled write protection 40-year data retention 106 erase/write cycles per word 8-pin DIP/SOP package 8-pin TSSOP (HT24LC02 only) Commerical temperature range (0°C to +70°C) General Description The HT24LC01/02 is a 1K/2K-bit serial read/write non-volatile memory device using the CMOS floating gate process.
Its 1024/2048 bits of memory are organized into 128/256 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 HT24LC01/02 devices may be connected to the same two-wire bus.
The HT24LC01/02 is guaranteed for 1M erase/write cycles and 40-year data retention.
