Pins designated as "NC" are typically unbonded pins. However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care
should be taken that the voltage applied on these pins does not exceed the V
CC
applied to the device. This will ensure proper operation.

Note 1:
Stress above those listed under “Absolute Maximum Ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.

The shortest allowable SK clock period = 1/f

SK clock speed (minimum SK period) is determined by the interaction of several AC parameters stated
in the datasheet. Within this SK period, both t

NM93C06 256-Bit Serial CMOS EEPROM
(MICROWIRE
TM
Synchronous Bus)
Pin Description
Chip Select (CS)
This is an active high input pin to NM93C06 EEPROM (the device)
and is generated by a master that is controlling the device. A high
level on this pin selects the device and a low level deselects the
device. All serial communications with the device is enabled only
when this pin is held high. However this pin cannot be permanently
tied high, as a rising edge on this signal is required to reset the
internal state-machine to accept a new cycle and a falling edge to
initiate an internal programming after a write cycle. All activity on the
SK, DI and DO pins are ignored while CS is held low.
Microwire Interface
A typical communication on the Microwire bus is made through the
CS, SK, DI and DO signals. To facilitate various operations on the
Memory array, a set of 7 instructions are implemented on NM93C06.
The format of each instruction is listed under Table 1.
Instruction
Each of the 7 instructions is explained under individual instruction
descriptions.
Start bit
This is a 1-bit field and is the first bit that is clocked into the device
when a Microwire cycle starts. This bit has to be “1” for a valid cycle
to begin. Any number of preceding “0” can be clocked into the
device before clocking a “1”.
Serial Clock (SK)
This is an input pin to the device and is generated by the master that
is controlling the device. This is a clock signal that synchronizes the
communication between a master and the device. All input informa-
tion (DI) to the device is latched on the rising edge of this clock input,
while output data (DO) from the device is driven from the rising edge
of this clock input. This pin is gated by CS signal.
Opcode
This is a 2-bit field and should immediately follow the start bit.
These two bits (along with 2 MSB of address field) select a
particular instruction to be executed.
Serial Input (DI)
This is an input pin to the device and is generated by the master
that is controlling the device. The master transfers Input informa-
tion (Start bit, Opcode bits, Array addresses and Data) serially via
this pin into the device. This Input information is latched on the
rising edge of the SCK. This pin is gated by CS signal.
Address Field
This is a 6-bit field and should immediately follow the Opcode bits.
In NM93C06, only the LSB bits are used for address decoding
during READ, WRITE and ERASE instructions. During these
three instructions (READ, WRITE and ERASE) the MSB 2 bits are
"don't care" (can be 0 or 1).During all other instructions, the MSB
2 bits are used to decode instruction (along with Opcode bits).
Serial Output (DO)
This is an output pin from the device and is used to transfer Output
data via this pin to the controlling master. Output data is serially
shifted out on this pin from the rising edge of the SCK. This pin is
active only when the device is selected.
Data Field
This is a 16-bit field and should immediately follow the Address
bits. Only the WRITE and WRALL instructions require this field.
D15 (MSB) is clocked first and D0 (LSB) is clocked last (both
