Signal description

During all operations, VCC must be held stable and within the specified valid range:

VCC(min) to VCC(max).

All of the input and output signals can be held high or low (according to voltages of VIL, VIH,

VOL or VOH, as specified in Table 10: "DC Characteristics (M93Sx6-W, device grade 6)".

These signals are described next.

2.1

Serial data output (Q)

This output signal is used to transfer data serially out of the device. Data is shifted out on

the rising edge of Serial Clock (C).

2.2

Serial data input (D)

This input signal is used to transfer data serially into the device. It receives instructions,

addresses, and the data to be written. Values are latched on the rising edge of Serial Clock

(C).

2.3

Serial clock (C)

This input signal provides the timing of the serial interface. Instructions, addresses, or data

present at Serial Data Input (D) are latched on the rising edge of Serial Clock (C). Data on

Serial Data Output (Q) changes after the rising edge of Serial Clock (C).

2.4

Chip select (S)

When this input signal is low, the device is deselected and Serial Data Output (Q) is at high

impedance. Unless an internal Write cycle is in progress, the device will be in the Standby

Power mode. Driving Chip Select (S) high selects the device, placing it in the Active Power

mode.

2.5

Protection register (PRE)

The Protection enable (PRE) signal must be driven High before and during the instructions

accessing the Protection Register.

2.6

Write protect (W)

This input signal is used to control the memory in write protected mode. When Write

Protect (W) is held low, writes to the memory are disabled, but other operations remain

enabled. Write Protect (W) must either be driven high or low, but must not be left floating.

2.7

VSS ground

VSS is the reference for the VCC supply voltage.

2.8

Supply voltage (VCC)

2.8.1

Operating supply voltage VCC

Prior to selecting the memory and issuing instructions to it, a valid and stable VCC voltage

within the specified [VCC(min), VCC(max)] range must be applied (see Table 5: "Operating

conditions (M93Sx6-W)"). This voltage must remain stable and valid until the end of the
