KSZ8863MLL/FLL/RLL TABLE 2-1: SIGNALS (CONTINUED) Pin Pin Type Description Number Name Note 2-1
SPI Slave mode: chip select (active-low) When SPISN is high, KSZ8863MLL/FLL/RLL is deselected and SPIQ is held in a high impedance state. 39 SPISN Ipd A high-to-low transition is used to initiate SPI data transfer. Note: An external pull-up is needed on this pin when using SPI or MDC/ MDIO-MIIM/SMI mode. 3.3V, 2.5V, or 1.8V digital V 40 VDDIO P DD input power supply for IO with well decou- pling capacitors 41 GND GND Digital ground 1.8V core power voltage output (internal 1.8V LDO regulator output) This 1.8V output pin provides power to both VDDA_1.8 and VDDC input pins. 42 VDDCO P Note: Internally, 1.8V LDO regulator input comes from VDDIO. Do not con- nect an external power supply to VDDCO pin. The ferrite bead is requested between analog and digital 1.8V core power.
Port 1 LED Indicators:
Default: Speed (refer to register 195 bit [5:4]) 43 P1LED1 Ipu/O
Strap option:
Force the speed on port 1 (P1SPD) PU = Force port 1 to 100BT if P1ANEN = 0 PD = Force port 1 to 10BT if P1ANEN = 0
Port 1 LED Indicators:
Default: Link/Act. (refer to register 195 bit [5:4]) 44 P1LED0 Ipd/O
Strap option:
Enable auto-negotiation on port 1 (P1ANEN) PU = Enable (better to pull up in design) PD = Disable (default) DS00002335B-page 8 2017 Microchip Technology Inc.
