DESCRIPTION
The IS24C32C is electrically erasable PROM
devices that use the standard 2-wire interface for
communications. The IS24C32C contains a
memory array of 32K-bits (4K x 8). Each device is
organized into 32 byte pages for page write mode.
This EEPROM operates in a wide voltage range of
1.8V to 5.5V to be compatible with most application
voltages. ISSI designed this device family to be a
practical, low-power 2-wire EEPROM solution.
The devices are available in 8-pin PDIP, 8-pin
SOIC, 8-pin TSSOP, 8-pad DFN, and 8-pin MSOP
packages.
The IS24C32C maintains compatibility with the
popular 2-wire bus protocol, so it is easy to use in
applications implementing this bus type. The
simple bus consists of the Serial Clock wire (SCL)
and the Serial Data wire (SDA). Using the bus, a
Master device such as a microcontroller is usually
connected to one or more Slave devices such as
this device. The bit stream over the SDA line
includes a series of bytes, which identifies a
particular Slave device, an instruction, an address
within that Slave device, and a series of data, if
appropriate. The IS24C32C has a Write Protect pin
(WP) to allow blocking of any write instruction
transmitted over the bus.

... Once all 32 bytes are received and the Stop condition has been sent by the Master, the internal programming cycle begins. At this point, all received data is written to the IS24C32C in a single Write cycle. All inputs are disabled until completion of the internal Write cycle. Acknowledge (ACK) Polling The disabling of the inputs can be used to take advantage of the typical Write cycle time ...

... ACK and transmit the 8-bit data byte stored at address location n+1. The Master should not acknowledge the transfer but should generate a Stop condition so the IS24C32C discontinues transmission. If 'n' is the last byte of the memory, the data from location '0' will be transmitted. (Refer to Figure 8. Current Address Read Diagram.) ...
