4 / 40 page  Analog Integrated Circuit Device Data 4 Freescale Semiconductor 908E624 TERMINAL CONNECTIONS MCU 43 48 VREFL VREFH ADC References These terminals are the reference voltage terminals for the analog-to- digital converter (ADC). MCU 44 47 VSSA VDDA ADC Supply Terminals These terminals are the power supply terminals for the analog-to-digital converter. MCU 45 46 EVSS EVDD MCU Power Supply Terminals These terminals are the ground and power supply terminals, 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 terminals are special-function, bidirectional I/O port terminals that are shared with other functional modules in the MCU. MCU 51 FLSVPP Test Terminal For test purposes only. Do not connect in the application. Analog 17 PWMIN Direct High Side Control Input This terminal allows the enabling and PWM control of the high side HS1 and HS2 terminals. Analog 18 RST_A Internal Reset Output This terminal is the reset output terminal of the analog die. Analog 19 IRQ_A Internal Interrupt Output This terminal is the interrupt output terminal of the analog die indicating errors or wake-up events. Analog 23 24 L1 L2 Wake-Up Inputs These terminals are the wake-up inputs of the analog chip. Analog 25 26 27 HS3 HS2 HS1 High Side Output These output terminals are low RDS(ON) high side switches. Analog 31 28 VSUP1 VSUP2 Power Supply Terminals These terminals are device power supply terminals. Analog 29 LIN LIN Bus This terminal represents the single-wire bus transmitter and receiver. Analog 30 34 GND AGND Power Ground Terminals These terminals are device power ground connections. Analog 33 VDD Voltage Regulator Output The +5.0 V voltage regulator output terminal is intended to supply the embedded microcontroller. Analog 35 VCC Amplifier Power Supply This terminal is the single +5.0 V power supply for the current sense operational amplifier. Analog 36 OUT Amplifier Output This terminal is the output of the current sense operational amplifier. Analog 37 38 -E +E Amplifier Inputs These terminals are the current sense operational amplifier inverted and non-inverted inputs. Analog 39 WDCONF Window Watchdog Configuration Terminal This input terminal is for configuration of the watchdog period and allows the disabling of the watchdog. Analog 40 RXD LIN Transceiver Output This terminal is the output of LIN transceiver. Table 1. Terminal Definitions (continued) A functional description of each terminal can be found in the Functional Terminal Description section beginning on page 18.
