Rev. 1.0
Power Supplies: Apply 3.3V to pin 10 of J4 and 5V to pin 10 of J2.
Control signals to the device can be connected through J2 and J4 (see Figure 1.1 and the electrical
schematic Figure 4.1)

Getting Started
Set JP1 to the SCLK setting
Apply clock source to pin 1 of J2
Apply 3.3V (1) or GND (0) to CLKDIV1 and CLKDIV2 pins allows the following:
-
-
-
-
-
-
Crystal included in the Demo Board is 12MHz (NDS applications can use 27MHz)
Set JP1 to XTAL position
Apply 3.3V (1) or GND (0) to CLKDIV1 and CLKDIV2 pins allows the following:
-
-
-
-
CLKDIV1 = CLKDIV2 = 0
73S8014R clock frequency = SCLK/8
73S8014RN/RT clock frequency = SCLK/6
CLKDIV1 = 0, CLKDIV2 =1 clock frequency = SCLK/4 (all)
CLKDIV1 = 1, CLKDIV2 =0 clock frequency = SCLK (all)
CLKDIV1 = CLKDIV2 = 1
CLKDIV1 = CLKDIV2 = 0
CLKDIV1 = 0, CLKDIV2 =1 clock frequency = 3MHz
CLKDIV1 = 1, CLKDIV2 = 0 – clock frequency = 12MHz
CLKDIV1 = CLKDIV2 = 1
12MHz XTAL – clock frequency = 1.5MHz
27MHz XTAL – clock frequency = 4.5MHz
12MHz XTAL – clock frequency = 3MHz
27MHz XTAL – clock frequency = 6.75MHz
12MHz XTAL – clock frequency = 12MHz
27MHz XTAL – Illegal setting. Clock is not guaranteed to be stable as the device spec
max CLK frequency is 20MHz.
12MHz XTAL – clock frequency = 6MHz
27MHz XTAL - clock frequency = 13.5MHz
clock frequency = 6MHz
clock frequency = SCLK/2 (all)
