Active-Semi’s EP5223LVM1-1 development platform is a complete hardware solution enabling users not only to evaluate the PAC5223 device, but also develop power applications revolving around this powerful and versatile ARM® Cortex®-M0 based mirco-controller. The module contains a PAC5223 Power Application Controller (MCU) and its internal peripherals once power is applied.
To aid in the application development the EP5223LVM1-1 offers access to each and every one of the PAC5223 device’s signals by means of a series of female header connectors.
The EP5223LVM1-1 can be used with various Graphical User Interface (GUI) software suites to externally control particular application’s features over the PAC5223 UART I/F. The ET-UARTISO-1 is a USB to UART adapter that can provide the required PC connectivity. If CooCox CoIDE or CoFlash are desired for development, the ET-COLINK-1 adapter is an inexpensive option for SWD Flash programming and debugging.
RD5223PT Battery operated Power Tool Reference Design
The EP5223PT1-1 reference design shows how the PAC5223 can be used to implement a high-current power tool application such as a battery-operated drill in a compact form-factor. This design is a 2.5cmx6cm PCB that can support up to 25A RMS and a peak current of 200W to 300W with the proper heat-sinking. Since the PAC5223 provides just the controller function, by selecting different FETs and component values, the power output of this design could be increased to much higher levels for different application requirements.
“TinyBLDC” reference design
The “TinyBLDC” reference design shows how the PAC5223 may be used to implement an Embedded Speed Controller (ESC) for drone and RC applications. This reference design supports BLDC with a single current shunt for motor current and can run up to 20V with an RMS output current of 17A. Since the PAC5223 provides just the controller function, by selecting different FETs and component values, the power output of this design could be increased to much higher levels for different application requirements.
“TinyFOC” reference design
The “TinyFOC” reference design shows how the PAC5223 may be used to implement an Embedded Speed Controller (ESC) for drone and RC applications. This reference design supports FOC with three phase current shunts for motor current and can run up to 20V with an RMS output current of 17A. Since the PAC5223 provides just the controller function, by selecting different FETs and component values, the power output of this design could be increased to much higher levels for different application requirements.
Supporting Evaluation Tools
The ET-COLINK-1 adapter allows the user to program and perform source level debugging of the target device using SWD from a PC. This adapter is required when using the CooCox CoIDE for development. This IDE and adapter will allow the user to program FLASH on the device, as well as perform source-level debugging of the application.
The ET-UARTISO-1 adapter allows the user to connect the graphical user interface (GUI) to the target board via USB. The adapter allows the user to access the UART serial channel on the PAC device, so that the GUI may be used for evaluation and debugging of an operating system.
