IS93C56A IS93C66A 2K-BIT/4K-BIT SERIAL ELECTRICALLY ERASABLE PROM AUGUST 2007 • Industry-standard Microwire Interface Non-volatile data storage Wide voltage operation Vcc = 1.8V to 5.5V Auto increment for efficient data dump • User Configured Memory Organization By 16-bit or by 8-bit • Hardware and software write protection Defaults to write-disabled state at power-up Software instructions for write-enable/disable • Enhanced low voltage CMOS E2PROM technology • Versatile, easy-to-use Interface Self-timed programming cycle Automatic erase-before-write Programming status indicator Word and chip erasable Chip select enables power savings • Durable and reliable 40-year data retention after 1M write cycles 1 million write cycles Unlimited read cycles Schmitt-trigger inputs • Industrial and Automotive Temperature Grade • Lead-free available The IS93C56A/66A are 2kb/4kb non-volatile, ISSI serial EEPROMs. They are fabricated using an enhanced CMOS design and process. The IS93C56A/66A contain power-efficient read/write memory, and organization of either 256/512 bytes of 8 bits or 128/256 words of 16 bits. When the ORG pin is connected to Vcc or left unconnected, x16 is selected when it is connected to ground, x8 is selected. The IS93C56A/66A are fully backward compatible with IS93C56/66. An instruction set defines the operation of the devices, including read, write, and mode-enable functions. To protect against inadvertent data modification, all erase and write instructions are accepted only while the devices are write-enabled. A selected x8 byte or x16 word can be modified with a single WRITE or ERASE instruction. Additionally, the two instructions WRITE ALL or ERASE ALL can program an entire array. Once a device begins its self-timed program procedure, the data out pin Dout can indicate the READY/ BUSY status by raising chip select CS . The selftimed write cycle includes an automatic erasebefore-write capability. The devices can output any number of consecutive bytes/words using a single READ instruction.

The IS93C56A/66A are 2kb/4kb non-volatile, ISSI serial EEPROMs. They are fabricated using an enhanced CMOS design and process. The IS93C56A/66A contain power-efficient read/write memory, and organization of either 256/512 bytes of 8 bits or 128/256 words of 16 bits. When the ORG pin is connected to Vcc or left unconnected, x16 is selected when it is connected to ground, x8 is selected. The IS93C56A/66A are fully backward compatible with IS93C56/66.

An instruction set defines the operation of the devices, including read, write, and mode-enable functions. To protect against inadvertent data modification, all erase and write instructions are accepted only while the devices are write-enabled. A selected x8 byte or x16 word can be modified with a single WRITE or ERASE instruction. Additionally, the two instructions WRITE ALL or ERASE ALL can program an entire array.
