Infineon CYPM1115-48LQXI

EZ-PD™ PMG1-B1 CYPM1115-48LQXI distinguishes itself for its Rp and Rd termination resistors and the tray packing. It is part of the EZ-PD™ PMG1-B1 family of highly integrated single-port USB-C Power Delivery (PD) solution with integrated buck-boost controllers.The Cortex®-M0 in EZ-PD™ PMG1-B1 devices is a 32-bit MCU, which is optimized for low-power operation with extensive clock gating. EZ-PD™ PMG1-B1 devices have 128 KB Flash and 32 KB ROM for non-volatile storage. ROM stores libraries for authentication and device drivers such as I2C, SPI, and so on. Flash provides the flexibility to store code for any customer feature and allows firmware upgrades to meet the latest USB power delivery specifications and application needs. The 16-KB RAM is used under software control to store the temporary status of system variables and parameters. A supervisory ROM that contains boot and configuration routines is provided.The USBPD subsystem contains the USBPD physical layer block and supporting circuits. The USBPD physical layer consists of a transmitter and receiver that communicate BMC encoded data over the CC channel per the PD 3.1 standard. All communication is half-duplex. The USBPD block includes all termination resistors (Rp and Rd) and their switches as required by the USB Type-C spec.The EZ-PD™ PMG1-B1 device family along with the accompanying firmware is fully compliant with revision 3.1 of the USB Power delivery specification. The device supports programmable power supply (PPS) operation at all valid voltages from 3.3 to 21 V and has a programmable switching frequency (150 to 600 kHz).

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.
