HK24C32

Two-Wire Serial EEPROM 32K, 64K (8-bit wide) FEATURES  Low voltage and low power operations:  HK24C32/HK24C64: VCC = 1.8V to 5.5V  Maximum Standby current < 1µA (typically 0.02µA and 0.06µA @ 1.8V and 5.5V respectively).  32 bytes page write mode.  Partial page write operation allowed.  Internally organized: 4,096 × 8 (32K), 8,192 × 8 (64K).  Standard 2-wire bi-directional serial interface.  Schmitt trigger, filtered inputs for noise protection.  Self-timed Write Cycle (5ms maximum).  800 kHz (5V), 400 kHz (1.8V, 2.5V, 2.7V) Compatibility.  Automatic erase before write operation.  Write protect pin for hardware data protection.  High reliability: typically 1, 000,000 cycles endurance.  100 years data retention.  Industrial temperature range (-40℃ to 85℃).  Standard 8-lead DIP/SOP/ MSOP/TSSOP/DFN and 5-lead SOT23/TSOT23 Pb-free packages. DESCRIPTION The HK24C32/24C64 series are 32,768/65,536 bits of serial Electrical Erasable and Programmable Read Only Memory, commonly known as EEPROM. They are organized as 4096/8192 words of 8 bits (one byte) each. The devices are fabricated with proprietary advanced CMOS process for low power and low voltage applications. These devices are available in standard 8-lead DIP, 8-lead SOP, 8-lead MSOP, 8-lead TSSOP, 8-lead DFN, 5-lead SOT23, and 5-lead TSOT23 packages. A standard 2-wire serial interface is used to address all read and write functions. Our extended VCC range (1.8V to 5.5V) devices enables wide sp...
