KK24LC16

TECHNICAL DATA 16K Serial EEPROM with I2C bus DESCRIPTION KK24LC16 The KK24LC16 is a 16K bit Electrically Erasable PROM. The chip is organized as eight blocks of 256 x 8 bit memory with a 2-wire serial interface. Low voltage design permits operation down to 2.5 volts with standby and active currents of only 5 µA and 1 mA respectively. The IZ24LC16B also has a page-write capability for up to 16 bytes of data. FEATURES • Single supply with operation down to 2.5V • Low power CMOS technology - 1 mA active current typical - 10 µA standby current typical at 5.5V - 5 µA standby current typical at 3.0V • Organized as 8 blocks of 256 bytes (8 x 256 x 8) • 2-wire serial interface bus, I2C compatible • Schmitt trigger inputs for noise suppression • Output slope control to eliminate ground bounce • 100 kHz (E-temp) and 400 kHz (C/I-temp) compatibility • Self-timed write cycle (including auto-erase) • Page-write buffer for up to 16 bytes • 2 ms typical write cycle time for page-write • Hardware write protect for entire memory • Can be operated as a serial ROM • 1,000,000 erase/write cycles guaranteed • Data retention > 200 years • Temperature range -40oC to +85oC PACKAGE TA = -40 ... +85 °C Figure 1.
