Signal description
2.1
Serial data output (SDO)
The output pin is used to transfer data serially out of the memory. Data is shifted out on the
falling edge of the serial clock.
2.2
Serial data input (SDI)
The input pin is used to transfer data serially into the device. Instructions, addresses, and
the data to be written, are each received this way. Input is latched on the rising edge of the
serial clock.
2.3
Serial clock (SCL)
The serial clock provides the timing for the serial interface (as shown in Figure 7 on page 13
and Figure 8 on page 14). The W/R bit, addresses, or data are latched, from the input pin,
on the rising edge of the clock input. The output data on the SDO pin changes state after the
falling edge of the clock input.
The M41T94 can be driven by a microcontroller with its SPI peripheral running in either of
the two following modes:
●
(CPOL, CPHA) = ('0', '0') or
●
(CPOL, CPHA) = ('1', '1').
For these two modes, input data (SDI) is latched in by the low-to-high transition of clock
SCL, and output data (SDO) is shifted out on the high-to-low transition of SCL (see Table 2
2.4
Chip enable (E)
When E is high, the memory device is deselected, and the SDO output pin is held in its high
impedance state. After power-on, a high-to-low transition on E is required prior to the start of
any operation.
