Description

K12

SPI Chip Select. Active low, 1.8V logic. Bring CS low to begin a SPI transaction, see Figure 167 and

Figure 168 for more information.

ADD_G0

Gain LUT Address Bit 0. Active high, 1.8V logic. No internal pull-up or pull-down resistance. Tie ADD_G0

to the logic output from a microcontroller or FPGA; do not float. If ADD_G0 is not used to set the LUT

address pointer, ground this ball.

L10

VDD_LO

LO Supply Voltage, 1.8V. Place 0.01μF and 1μF decoupling capacitors close to VDD_LO.

L11

VDD_BG

Band-Gap Reference Supply Voltage, 1.8V. Place 0.01μF and 1μF decoupling capacitors close to

VDD_BG. Ideally for proper NVM load operation, apply the VDD_BG voltage after all other supplies have

been turned on and RST has been set high. If this is not possible, as is the case if all supply voltages are

applied together, ensure to set RST high and run the NVM refresh commands.
