instruction begins with a start bit of the logical “1” or  
HIGH. Following this are the opcode (2 bits),  
address field (8 or 9 bits), and data, if appropriate. The  
clock signal may be held stable at any moment to  
suspend the device at its last state, allowing clock-  
speed flexibility. Upon completion of bus  
communication, CS would be pulled LOW. The device  
then would enter Standby mode if no internal  
programmingisunderway.

The READ instruction is the only instruction that outputs  
serial data on the DOUT pin. After the read instruction and  
address have been decoded, data is transferred from the  
selectedmemoryregisterintoa serialshiftregister.(Please

Applications  
The IS93C56A/66A are very popular in many  
applications which require low-power, low-density  
storage. Applications using these devices include  
industrial controls, networking, and numerous other  
Low Voltage Read  
The IS93C56A/66A are designed to ensure that data read  
operations are reliable in low voltage environments. They  
provide accurate operation with Vcc as low as 1.8V.  
consumer electronics.  
Endurance and Data Retention  
Auto Increment Read Operations  
The IS93C56A/66A are designed for applications requiring  
up to 1M programming cycles (WRITE, WRALL, ERASE  
and ERAL). They provide 40 years of secure data retention  
withoutpoweraftertheexecutionof1Mprogrammingcycles.  
In the interest of memory transfer operation applications,  
the IS93C56A/66A are designed to output a continuous  
stream of memory content in response to a single read  
operation instruction. To utilize this function, the system  
asserts a read instruction specifying a start location ad-  
dress. Once the 8 or 16 bits of the addressed register have  
been clocked out, the data in consecutively higher address  
locations is output. The address will wrap around continu-  
ously with CS HIGH until the chip select (CS) control pin is  
brought LOW. This allows for single instruction data dumps  
to be executed with a minimum of firmware overhead.  
Device Operations  
The IS93C56A/66A are controlled by a set of  
instructions which are clocked-in serially on the Din pin.  
Before each low-to-high transition of the clock (SK), the  
CS pin must have already been raised to HIGH, and the  
Din value must be stable at either LOW or HIGH. Each
