HK24C64 - Two-Wire Serial EEPROM

Download the HK24C64 datasheet PDF. This datasheet also covers the HK24C32 variant, as both devices belong to the same two-wire serial eeprom family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
