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
spectrum of applications.

(E) STANDBY MODE
The EEPROM goes into low power STANDBY mode after a fresh power up, after receiving a STOP bit
in read mode, or after completing a self-time internal programming operation.

DEVICE ADDRESSING
The 2-wire serial bus protocol mandates an 8 bits device address word after a START bit condition to invoke
a valid read or write command. The first four most significant bits of the device address must be 1010,
which is common to all serial EEPROM devices. The next three bits are device address bits. These three
device address bits (5th, 6th and 7th) are to match with the external chip select/address pin states. If a match
is made, the EEPROM device outputs an ACKNOWLEDGE signal after the 8th read/write bit, otherwise the
chip will go into STANDBY mode. However, matching may not be needed for some or all device address
bits (5th, 6th and 7th) as noted below. The last or 8th bit is a read/write command bit. If the 8th bit is at VIH
then the chip goes into read mode. If a “0” is detected, the device enters programming mode.
