The S-29UX94A Series is low power 1K/2K/4K-bit serial E
2
PROMs with a
low operating voltage range. They are organized as 64-word
16-bit,
128-word
16-bit and 256-word 16-bit, respectively. Each is capable of
sequential read, where addresses are automatically incremented in 16-bit
blocks.
The S-29UX94A Series is capable of protecting the memory, 50% of
which can be protected starting from address 00.
Interface is structured so that this IC can be directly connected to the
CPU with serial ports. 8-bit instructions make it easy to prepare your
own software.

Figure 5 Read Timing (S-29U394A)
Instructions (in the order of start-bit, instruction, address, and data) are latched to DI in synchronization with the
rising edge of SK after CS goes low. A start-bit can only be recognized when the high of DI is latched at the rising
edge of SK after changing CS to low, it is impossible for it to be recognized as long as DI is low, even if there are SK
pulses after CS goes low. Instruction finishes when CS goes high, where it must be high between commands during
t
CDS
.
All input, including DI and SK signals, is ignored while CS is high, which is stand-by mode. The start bit + instruction,
address, and data are 8-bit instructions. This makes it easy to prepare your own software using a serial interface
incorporated into the CPU.
1.
READ
The READ instruction reads data from a specified address. After A0 is latched at the risig edge of SK, 16-bit
data is continuously output in synchronization with the falling edge of SK.
When all of the data (D
15
to D
0
) in the specified address has been read, data in the next address can be read
with the input of another SK clock. Thus, the data over whole area of the memory can be read by continuously
inputting SK clocks as long as CS is low.
The last address (An
L
A1 A0 = 1
L
11) rolls over to the top address (An
L
A1 A0 = 0
L
00).

Figure 6 WRITE Timing (S-29U394A)
The PROGRAM instruction automatically begins writing to the non-volatile memory when CS goes high at the
completion of the specified clock input.
The write operation is completed in 10 ms (t
PR
Max.), and the typical write period is less than 5 ms. In the S-
29UX94A Series, it is easy to VERIFY the completion of the write operation in order to minimize the write cycle by
setting CS to low and checking the DO pin, which is low during the write operation and high after its completion.
This VERIFY procedure can be executed over and over again.
There are two methods to detect a change in the DO output. One is to detect a change from low to high setting CS
to low, and the other is to detect a change from low to high as a result of repetitous operations of returning the CS to
high after setting CS to low and checking the DO output.
Because all SK and DI inputs are ignored during the write operation, any input of instruction will also be disregarded.
When DO outputs high after completion of the write operation or if it is in the high-impedence state (Hi-Z), the input
of instructions is available. Even if the DO pin remains high, it will enter the high-impedence state upon the
recognition of a high of DI (start-bit) attached to the rising edge of an SK pulse.
DI input should be low during the VERIFY procedure.
This instruction writes 16-bit data to a specified address.
After changing CS to low, input a start-bit, op-code (PROGRAM), address, and 16-bit data. If there is a data
overflow of more than 16 bits, only the last 16-bits of the data is considered valid. Changing CS to high will start the
PROGRAM operation. It is not necessary to make the data "1" before initiating the PROGRAM operation.

3. Write enable (PEN) and Write disable (PDS)
The PEN instruction puts the S-29UX94A Series into write enable mode, which accepts PROGRAM instruction. The
PDS instruction puts the S-29UX94A Series into write disable mode, which refuses PROGRAM instruction.
The S-29UX94A Series powers on in write disable mode, which protects data against unexpected, erroneous write
operations caused by noise and/or CPU malfunctions. It should be kept in write disable mode except when performing
write operations.
Receiving a Start-Bit
Three-wire Interface (DI-DO direct connection)
Figure 7 PEN/PDS Timing
A start-bit can be recognized by latching the high level of DI at the rising edge of SK after changing CS to low (Start-
Bit Recognition). The write operation begins by inputting the write instruction and setting CS to high. The DO pin
then outputs low during the write operation and high at its completion by setting CS to low (Verify Operation).
Therefore, only after a write operation, in order to accept the next command by having CS go low, the DO pin is
switched from a state of high-impedence to a state of data output; but if it recognizes a start-bit, the DO pin returns
to a state of high-impedence (see Figure 3).
Make sure that data output from the CPU does not interfere with the data output from the serial memory IC when
you configure a 3-wire interface by connecting DI input pin and DO output pin. Such interference may cause a start-
bit fetch problem.
Although the normal configuration of a serial interface is a 4-wire interface to CS, SK, DI, and DO, a 3-wire interface
is also a possibility by connecting DI and DO. However, since there is a possibility that the DO output from the serial
memory IC will interfere with the data output from the CPU with a 3-wire interface, install a resistor between DI and
DO in order to give preference to data output from the CPU to DI (See Figure 8).
Please refer Application Note "S-29 & S-93C series EEPROMs Tips, Tricks & Traps" for equivalent circuit of each pin.

The S-29UX94A Series is capable of protecting the memory. So, the contents of the memory will not be miswritten due to
error run or malfunction of the CPU. When the PROTECT terminal is connected to GND or OPEN, write to Bank 1 in the
memory array is prohibited (50% of the memory can be protected starting from address 00). Because the pull-down
resistance is connected to the PROTECT terminal internally, the memory can be automatically protected when the PROTECT
terminal is OPEN. When the protection is valid, the data in the memory of Bank 1 will not be rewritten. However, because
the write control circuit inside the IC functions, the next instruction cannot be executed during the time period of writing (t
PR
).
While write instruction is being input and write is being executed, always connect the PROTECT terminal to "H," "L" or OPEN,
and leave the input signal unchanged (see Figure 11).
