SEIKO NPC CORPORATION —7
MICROCONTROLLER INTERFACE
The SM6451A uses a 3-wire serial interface comprising MDT (data), MCK (clock) and MLEN (latch enable)
to select channels and attenuation levels for the addressed device.
Input Timing
The microcontroller data input timing is shown in figure 1.
Data is shifted into the internal shift register on the rising edge of MCK, and the attenuation value is updated on
the rising edge of MLEN. Accordingly, data on MDT should be changed on the falling edge of MCK.
Note, however, a minimum of 16 MCK input pulses are required.
Data Format
The format of microcontroller input data is shown in figure 2.
D15, D14
Don’t care.
D13, D12
Chip address bits. D13 corresponds to ADRS1 and D12 corresponds to ADRS2. The device is addressed only
when ADRS1:ADRS2 matches D13:D12.
Example 1: If D13 = LOW, D12 = HIGH and ADRS1 = LOW, ADRS2 = LOW, then the device is not
addressed since ADRS2 and D12 do not match.
Example 2: If D13/D12 = LOW and ADRS1/ADRS2 = LOW, then the device is addressed and all input data
is read and the attenuation settings updated.
D11, D10
Don’t care.
