IS24C64  
65,552-BIT SERIAL ELECTRICALLY  
ERASABLE PROM  
ISSI
ADVANCE INFORMATION  
OCTOBER 1997  
FEATURES  
OVERVIEW  
• 400 KHz (5V) Compatibility  
• Low power CMOS  
The IS24C64 provides 65,536 bits of serial electrically  
erasableandprogrammablereadonlymemory(EEPROM)  
organized as 8197 words of 8 bits each. It is fabricated  
using ISSI’s advanced CMOS EEPROM technology and  
operates from a single supply.  
– Active current less than 3.0 mA  
– Standby current less than 35 µA  
• Operating voltage: 4.5V to 5.5V  
• Hardware write protection  
– Write control pin  
• Internally organized: 8192 x 8  
• 32 byte page write mode (partial page writes  
allowed)  
The IS24C64 is internally organized as 256 pages of 32  
bytes each. Random word addressing requires 12/13 bit  
data word address bank. The IS24C64 cascadable fea-  
ture allows up to 8 devices to share a common 2-wire bus.  
Included is a bidirectional serial data bus synchronized by  
a clock offering flexible byte write and a faster 32-byte  
pagewrite.Awriteprotectpincanprotectdataintheupper  
quadrant of memory.  
• Two-wire serial interface  
• Bidirectional data transfer protocol  
• Self timed write cycles (10 ms max)  
• High-reliability  
– Endurance: 1 million cycles per byte  
– Data retention: 100 years  
• Industrial temperature available  
• 8-pin PDIP or SOIC packages  
PIN DESCRIPTIONS  
Serial Clock (SCL) - The SCL input is used to positive  
edgeclockalldataintothedevice.IntheREADmode,data  
is clocked out on the falling edge of SCL.  
SerialData(SDA)-TheSDApinisabidirectionalpinused  
to transfer data into and out of the device. Data may  
change only when SCL is LOW. It is an open-drain output,  
and may be wire-ORed with any number of open-drain or  
open-collector outputs.  
PIN CONFIGURATION  
8-Pin DIP and SOIC  
Device/Page Addresses (A0, A1, and A2):  
The A2, A1 and A0 pins are device address inputs that are  
hard wired or left not connected for hardware compatibility  
with IS24C64. When the pins are hardwired, as many as  
eight 64K devices may be addressed on a single bus  
system (device addressing is discussed in detail under the  
Device Addressing section). When the pins are not  
hardwired, the default A2, A1 and A0 are zero.

PIN DESCRIPTIONS  
Write Control (WC) - The Write Control input is used to  
disable any attempt to write to the memory. When HIGH,  
the upper quadrant (16K bits)of array is protected against  
write operations; when LOW, the write function is normal.  
The part can be read independent of the state of WC pin.  
When not connected this pin will be pulled LOW.
