Description1. The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.2. STM8 applications use the USB full speed interface to communicate with STMicroelectronics ST Visual Develop (STVD) or ST Visual Program (STVP) software.3. STM32 applications use the USB full speed interface to communicate with Atollic, IAR, Keil or TASKING integrated development environments.Key Features1. 5V power supplied by a USB connector2. USB 2.0 full speed compatible interface3. USB standard A to mini B cable4. SWIM specific features5. 1.65 V to 5.5 V application voltage supported on SWIM interface6. SWIM low-speed and high-speed modes supported7. SWIM programming speed rate: 9.7 Kbytes/s in low speed and 12.8 Kbytes/s in high speed8. SWIM cable for connection to the application via an ERNI standard vertical (ref: 284697 or 214017) or horizontal (ref: 214012) connector9. SWIM cable for connection to the application via a pin header or a 2.54 mm pitch connector10. JTAG specific features11. 1.65 V to 3.6 V application voltage supported on the JTAG interface and 5 V tolerant inputs12. JTAG cable for connection to a standard JTAG 20-pin pitch 2.54 mm connector13. Direct firmware update feature supported (DFU)14. Status LED which blinks during communication with the PC15. Operating temperature 0 to 50 °CApplication ExampleConnecting the PC and STM8/STM32 application board through ST-LINK/V2 to establish hardware connectionConnection with STM8 applicationsThe ST-LINK/V2 should be connected to the STM8 application via the SWIM cable. Two SWIM cables are delivered with the product:- SWIM flat ribbon with a standard ERNI connector at one end and a 4-pin connector at the other end- SWIM flat ribbon ended with a 4-pin, 2.54 mm, low-cost connector on two sidesConnection with STM32 applicationsFor STM32 developments the ST-LINK/V2 must be connected to the application using the standard 20-pin female-female JTAG flat ribbon provided.ST-LINK/V2 StatusThe LED labeled COM on top of the ST-LINK/V2 shows the ST-LINK/V2 status (whatever the connection type). When the:1. LED is blinking RED: the first USB enumeration with the PC is taking place. If it keeps blinking RED, maybe the USB driver is NOT found.2. LED is RED: communication between ST-LINK/V2 and the PC is established (end of enumeration).3. LED is blinking GREEN/RED: data are being exchanged between the target and the PC.4. LED is GREEN: the last communication has been successful.5. LED is ORANGE: ST-LINK/V2 communication with the target has failed.Specification: Package Weight One Package Weight 0.10kgs / 0.23lb One Package Size 16cm * 9cm * 5cm / 6.3inch * 3.54inch * 1.97inch Qty per Carton 96 Carton Weight 9.60kgs / 21.16lb Carton Size 48cm * 36cm * 40cm / 18.9inch * 14.17inch * 15.75inch Loading Container 20GP: 385 cartons * 96 pcs = 36960 pcs40HQ: 895 cartons * 96 pcs = 85920 pcs
