4 / 60 page Analog Integrated Circuit Device Data 4 Freescale Semiconductor 908E621 PIN CONNECTIONS MCU 45 48 VSSA/VREFL VDDA/VREFH ADC Supply and Reference Pins These pins are the power supply and voltage reference pins for the analog-to-digital converter (ADC). MCU 46 47 EVSS EVDD MCU Power Supply Pins These pins are the ground and power supply pins, respectively. The MCU operates from a single power supply. MCU 49 50 52 53 54 PTA4/KBD4 PTA3/KBD3 PTA2/KBD2 PTA1/KBD1 PTA0/KBD0 Port A I/Os These pins are special function, bidirectional I/O port pins that are shared with other functional modules in the MCU. MCU 51 FLSVPP Test Pin For test purposes only. Do not connect in the application. Analog 11 RST_A Internal Reset This pin is the bidirectional reset pin of the analog die. Analog 12 IRQ_A Internal Interrupt Output This pin is the interrupt output pin of the analog die indicating errors or wake-up events. Analog 13 LIN LIN Bus This pin represents the single wire bus transmitter and receiver. Analog 14 A0CST Analog Input Trim Pin This is the analog input trim pin for the A0 input. This is to connect a known fixed resistor value to trim the current source measurement. Analog 15 A0 Analog Input Pin This pin is an analog input port with selectable source values. Analog 16 19 25 30 GND1 GND2 GND3 GND4 Power Ground Pins These pins are device power ground connections. Analog 29 26 20 17 HB1 HB2 HB3 HB4 Half-bridge Outputs This device includes power MOSFETs configured as four half-bridge driver outputs. These outputs may be configured for DC motor drivers, or as high side and low side switches. Note: The HB3 and HB4 have a lower RDS(ON) then HB1 and HB2. Analog 18 21 27 28 31 32 35 VSUP1 VSUP2 VSUP3 VSUP4 VSUP5 VSUP6 VSUP7 Power Supply Pins These pins are device power supply pins. –22 23 NC NC No Connect These pins are not connected. Analog 24 TESTMODE TESTMODE Input Pin for test purpose only. In application this pin needs to be tied GND. Analog 34 35 HS1a HS1b High Side HS1 Output This output pin is a low RDS(ON) high side switch. Analog 36 38 HS2 HS3 High Side HS2 Output High Side HS3 Output These output pins are low RDS(ON) high side switches. Analog 39 H0 Hall-Effect Sensor / General Purpose Input This pin provides an input for a Hall-effect sensor or general purpose input. Analog 40 L0 Wake-up Input This pin provides an high voltage input, which is wake-up capable. Analog 41 HVDD Switchable VDD Output This pin is a switchable VDD output for driving resistive loads requiring a regulated 5.0 V supply; e.g. potentiometers. Analog 42 VDD Voltage Regulator Output The +5. V voltage regulator output pin is intended to supply the embedded microcontroller. Table 1.
