IS93C76A IS93C86A
ISSI ®
8K-BIT/16K-BIT SERIAL ELECTRICALLY
ERASABLE PROM
Preliminary Information
MAY 2005
FEATURES
DESCRIPTION
• Industry-standard Microwire Interface
— Non-volatile data storage
— Low voltage operation:
Vcc = 1.8V to 5.5V -2
Vcc = 2.5V to 5.5V -3
— Full TTL compatible inputs and outputs
— Auto increment for efficient data dump
• User Configured Memory Organization
— By 16-bit or by 8-bit
IS93C76A/86A are 8kb/16kb non-volatile, ISSI ®
serial EEPROMs. They are fabricated using an
enhanced CMOS design and process. IS93C76A/
86A contains power-efficient read/write memory,
and organization of either 1,024/2,048 bytes of 8
bits or 512/1,024 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.
• 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
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 device are write-enabled.
• Versatile, easy-to-use Interface
A selected x8 byte or x16 word can be modified
— Self-timed programming cycle
— Automatic erase-before-write
with a single WRITE or ERASE instruction.
Additionally, the two instructions WRITE ALL or DataShee
— Programming status indicator
— Word and chip erasable
DataSheet4U.EcoRmASE ALL can program an entire array. Once a
device begins its self-timed program procedure,
— Chip select enables power savings
the data out pin (Dout) can indicate the READY/
• Durable and reliable
BUSY status by raising chip select (CS). The self-
— 40-year data retention after 1M write cycles
timed write cycle includes an automatic erase-
— 1 million write cycles
before-write capability. The devices can output

single READ instruction.
• Industrial and Automotive Temperature Grade
• Lead-free available
