CMOS SERIAL E2PROM
S-93C86B
The S-93C86B is a high speed, low current
consumption, 16 K-bit serial E2PROM with a wide
operating voltage range. It is organized as 1024-word
× 16-bit, respectively. This product is capable of
sequential read, at which time addresses are
automatically incremented in 16-bit blocks. The
instruction code is compatible with the NM93CS86.

4. Writing (WRITE, ERASE, WRAL, ERAL)
A write operation includes four write instructions: data write (WRITE), data erase (ERASE), chip write
(WRAL), and chip erase (ERAL).
A write instruction (WRITE, ERASE, WRAL, ERAL) starts a write operation to the memory cell when a
low level is input to CS after a specified number of clocks have been input. The SK and DI inputs are
invalid during the write period, so do not input an instruction.
Input an instruction while the output status of the DO pin is high or high impedance (Hi-Z).
A write operation is valid only in program enable mode (refer to “5. Write enable (EWEN) and write
disable (EWDS)”).
4.1 Verify operation
A write operation executed by any instruction is completed within 4 ms (write time tPR: typically 2
ms), so if the completion of the write operation is recognized, the write cycle can be minimized. A
sequential operation to confirm the status of a write operation is called a verify operation.
(1) Operation
After the write operation has started (CS = low), the status of the write operation can be verified
by confirming the output status of the DO pin by inputting a high level to CS again. This
sequence is called a verify operation, and the period that a high level is input to the CS pin after
the write operation has started is called the verify operation period.
The relationship between the output status of the DO pin and the write operation during the
verify operation period is as follows.
• DO pin = low: Writing in progress (busy)
• DO pin = high: Writing completed (ready)
(2) Operation example
There are two methods to perform a verify operation: Waiting for a change in the output status
of the DO pin while keeping CS high, or suspending the verify operation (CS = low) once and
then performing it again to verify the output status of the DO pin. The latter method allows the
CPU to perform other processing during the wait period, allowing an efficient system to be
designed.
Caution 1. Input a low level to the DI pin during a verify operation.
2. If a high level is input to the DI pin at the rise of SK when the output status of the DO
pin is high, the S-93C86B latches the instruction assuming that a start bit has been
input. In this case, note that the DO pin immediately enters a high-impedance (Hi-Z)
state.
