STEVAL-PCC002V1

STEVAL-PCC002V1 Low speed USB to serial bridge based on ST7263B Data Brief Features ■ PC executable software for HID communication ■ CTS/RTS flow control ■ Two LEDs to indicate traffic direction ■ In-circuit programming capability through ICC connector ■ Wrapping area capability with access to MCU I/Os ) s ( ct u d o r P e Description t e l o The board is a complete evaluation board for a serial port bridge as well as an evaluation board for ST72F63B/60 devices. This application is used to interface devices with a serial port (RS232 type) and a host-computer USB port. USB data transfers comply with HID-class protocols. The bridge is based on a USB low-speed microcontroller which provides a maximum guaranteed USB transfer rate of 800 bytes per second. The bridge application is evaluated on a PC by running a dedicated applet that controls and monitors data transfers on both the USB and serial COM ports. The included hardware provides in-circuit crogramming (ICP) capabilities for the microcontroller and almost all the MCU I/ Os are available on expansion connectors to evaluate different applications. The RS232 part can be separated by removing the appropriate soldering joints (shunts). This can be used to modify certain firmware or hardware parameters for evaluation or customization purposes. bs STEVAL-PCC002V1 O ) s ( t c u d o r P e t e l o s b O October 2007 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 VBUS DD+ GND VDD 7 6 15 16 19 100nF C10 USBDM USBDP PD0/AIN8 PD1/AIN9 PD2/AIN10 PD3/AIN11 PD4 PD5 PD6 PD7 PC0/RDI PC1/TDO PC2/USBOE PB0 (10mA)/AIN0 PB1 (10mA)/AIN1 PB2 (10mA)/AIN2 PB3 (10mA)/AIN3 PB4 (10mA)/IT5/AIN4 PB5 (10mA)/IT6/AIN5 PB6 (10mA)/IT7/AIN6 PB7 (10mA)/IT8/AIN7 PA0/MCO PA1 (25mA)/SDA/ICCDATA PA2 (25mA)/SCL/ICCCLK PA3/EXTCLK PA4/ICAP1/IT1 PA5/ICAP2/IT2 PA6/COMP1/IT3 PA7/COMP2/IT4 VDD 2 4 6 8 10 ICC FEATURE 1 3 5 7 9 P3 10K PA1/ICCDATA PA2/ICCCLK RESET R6 VPP ST72F63B_QFN40 ST72F60_QFN40(Port D not available) VSSA VSS USBDM USBDP USBVCC VDD VDDA NC NC Vpp/TEST RESET OSCIN 2 10 4 3 USBVCC 5 C8 10nF VPP RESET 14 OSCOUT OSCIN U1 32 PD0 33 PD1 34 PD2 35 PD3 36 PD4 37 PD5 38 PD6 39 PD7 13 PC0 12 PC1 11 PC2 25 PB0 24 PB1 23 PB2 22 PB3 21 PB4 20 PB5 18 PB6 17 PB7 1 PA0 40 PA1/ICCDATA 31 PA2/ICCCLK 30 PA3 29 PA4 28 PA5 27 PA6 26 PA7 VDD 1 PD7 3 PD5 5 PD3 7 PA1/ICCDATA 9 PA3 11 PA5 13 PA7 15 P1 PC2 PC0 PD0 PB6 PB4 PB2 PB0 R4 220 2 4 6 8 10 12 14 16 LED1 YELLOW LED VDD Header8X2 1 3 5 7 9 11 13 15 P2 Header8X2 2 4 6 8 10 12 14 16 USBVCC PC1 PD1 PB7 PB5 PB3 PB1 VDD PD6 PD4 PD2 PA0 PA2/ICCCLK PA4 PA6 s b O R5 220 LED2 GREENLED t e l o + C2 10uF/6.3V 1k5 R2 470 8 9 10 11 1 6 2 7 3 8 4 9 5 D Connector9 J2 r P e 100nF C3 1 2 3 4 VDD 18pF C4 R3 XT1 24MHz_NX2520SA OSCIN d o r t c u ) (s USB CON J1 18pF C1 2 2/4 1 s b O t e l o 4 P e 3 9 16 8 17 SHDN NC V- VCC V+ U3 SHDN CTS RxD RTS TxD SH6 SH5 SH4 SH3 SH2 PB0 PB4 PC0 PB1 PC1 NC GND C1+ C1C2+ C2- SH1 ST3222E C11 100nF SHDN 20 14 7 100nF 19 3 VDD 100nF C7 C5 1 11 18 10 CTS 15 RxD 12 RTS 13 TxD 2 4 5 6 C9 100nF C6 100nF Figure 1.
