125°C OPERATION 3-WIRE SERIAL
E2PROM FOR AUTOMOTIVE
Rev.6.1_00
The S-93A86A is a high temperature operation 3-wire serial E2PROM for automotive components. The S-93A86A has the
capacity of 16 K-bit, and the organization is 1024-word × 16-bit. It is capable of sequential read, at which time addresses are
automatically incremented in 16-bit blocks. The communication method is by the Microwire bus.

3. Reading (READ)
The READ instruction reads data from a specified address.
After CS has gone high, input an instruction in the order of the start bit, read instruction, and address. Since the last
input address (A0) has been latched, the output status of the DO pin changes from high impedance (High-Z) to low,
which is held until the next rise of SK. 16-bit data starts to be output in synchronization with the next rise of SK.
3. 1 Sequential read
After the 16-bit data at the specified address has been output, inputting SK while CS is high automatically
increments the address, and causes the 16-bit data at the next address to be output sequentially. The above
method makes it possible to read the data in the whole memory space. The last address (A9 A1 A0 = 1
1 1) rolls over to the top address (A9 A1 A0 = 0 0 0).
