3 / 28 page Analog Integrated Circuit Device Data Freescale Semiconductor 3 33993 PIN CONNECTIONS PIN CONNECTIONS Figure 3. 33993 Pin Connections Table 1. 33993 Pin Definitions A functional description of each pin can be found in the Functional Pin Description section beginning on page 9. Pin Number Pin Name Formal Name Definition 1 GND Ground Ground for logic, analog, and switch to battery inputs. 2 SI SPI Slave In SPI control data input pin from MCU to the 33993. 3 SCLK Serial Clock SPI control clock input pin. 4 CS Chip Select SPI control chip select input pin from MCU to the 33993. Logic 0 allows data to be transferred in. 5–8 25–28 SP0–3 SP4–7 Programmable Switches 0–7 Programmable switch-to-battery or switch-to-ground input pins. 9–15, 18–24 SG0–6, SG13–7 Switch-to-Ground Inputs 0–13 Switch-to-ground input pins. 16 VPWR Battery Input Battery supply input pin. Pin requires external reverse battery protection. 17 WAKE Wake-Up Open drain wake-up output. Designed to control a power supply enable pin. 29 INT Interrupt Open-drain output to the MCU. Used to indicate an input switch change of state. 30 AMUX Analog Multiplex Output Analog multiplex output. 31 VDD Voltage Drain Supply 3.3/5.0 V supply. Sets SPI communication level for the SO driver. 32 SO SPI Slave Out Provides digital data from 33993 to the MCU. SO 1 SP7 SP6 SP5 SP4 SG7 SG8 SG9 SG10 SG11 SG13 WAKE SG12 INT VDD AMUX GND SP0 SP1 SP2 SP3 SG0 SG1 SG2 SG3 SG4 SG6 VPWR SG5 CS SI SCLK 8 9 10 11 12 13 14 15 16 3 4 5 6 7 2 32 25 24 23 22 21 20 19 18 17 30 29 28 27 26 31 |
