13 / 140 page  Document Number: 001-84932 Rev. *N Page 12 of 139 PSoC® 5LP: CY8C58LP Family Datasheet 3. Pin Descriptions IDAC0, IDAC1, IDAC2, IDAC3. Low-resistance output pin for high-current DACs (IDAC). Opamp0out, Opamp1out, Opamp2out, Opamp3out. High current output of uncommitted opamp.[7] Extref0, Extref1. External reference input to the analog system. SAR0 EXTREF, SAR1 EXTREF. External references for SAR ADCs Opamp0-, Opamp1-, Opamp2-, Opamp3-. Inverting input to uncommitted opamp. Opamp0+, Opamp1+, Opamp2+, Opamp3+. Noninverting input to uncommitted opamp. GPIO. Provides interfaces to the CPU, digital peripherals, analog peripherals, interrupts, LCD segment drive, and CapSense.[7] I2C0: SCL, I2C1: SCL. I2C SCL line providing wake from sleep on an address match. Any I/O pin can be used for I2C SCL if wake from sleep is not required. I2C0: SDA, I2C1: SDA. I2C SDA line providing wake from sleep on an address match. Any I/O pin can be used for I2C SDA if wake from sleep is not required. Ind. Inductor connection to boost pump. kHz XTAL: Xo, kHz XTAL: Xi. 32.768-kHz crystal oscillator pin. MHz XTAL: Xo, MHz XTAL: Xi. 4 to 25-MHz crystal oscillator pin. nTRST. Optional JTAG Test Reset programming and debug port connection to reset the JTAG connection. SIO. Provides interfaces to the CPU, digital peripherals and interrupts with a programmable high threshold voltage, analog comparator, high sink current, and high impedance state when the device is unpowered. SWDCK. SWD Clock programming and debug port connection. SWDIO. SWD Input and Output programming and debug port connection. TCK. JTAG Test Clock programming and debug port connection. TDI. JTAG Test Data In programming and debug port connection. TDO. JTAG Test Data Out programming and debug port connection. TMS. JTAG Test Mode Select programming and debug port connection. TRACECLK. Cortex-M3 TRACEPORT connection, clocks TRACEDATA pins. TRACEDATA[3:0]. Cortex-M3 TRACEPORT connections, output data. SWV. SWV output. USBIO, D+. Provides D+ connection directly to a USB 2.0 bus. May be used as a digital I/O pin; it is powered from VDDD instead of from a VDDIO. Pins are Do Not Use (DNU) on devices without USB. USBIO, D-. Provides D- connection directly to a USB 2.0 bus. May be used as a digital I/O pin; it is powered from VDDD instead of from a VDDIO. Pins are Do Not Use (DNU) on devices without USB. VBOOST. Power sense connection to boost pump. VBAT. Battery supply to boost pump. VCCA. Output of the analog core regulator or the input to the analog core. Requires a 1uF capacitor to VSSA. The regulator output is not designed to drive external circuits. Note that if you use the device with an external core regulator (externally regulated mode), the voltage applied to this pin must not exceed the allowable range of 1.71 V to 1.89 V. When using the internal core regulator, (internally regulated mode, the default), do not tie any power to this pin. For details see Power System on page 26. VCCD. Output of the digital core regulator or the input to the digital core. The two VCCD pins must be shorted together, with the trace between them as short as possible, and a 1uF capacitor to VSSD. The regulator output is not designed to drive external circuits. Note that if you use the device with an external core regulator (externally regulated mode), the voltage applied to this pin must not exceed the allowable range of 1.71 V to 1.89 V. When using the internal core regulator (internally regulated mode, the default), do not tie any power to this pin. For details see Power System on page 26. VDDA. Supply for all analog peripherals and analog core regulator. VDDA must be the highest voltage present on the device. All other supply pins must be less than or equal to VDDA. VDDD. Supply for all digital peripherals and digital core regulator. VDDD must be less than or equal to VDDA. VSSA. Ground for all analog peripherals. VSSB. Ground connection for boost pump. VSSD. Ground for all digital logic and I/O pins. VDDIO0, VDDIO1, VDDIO2, VDDIO3. Supply for I/O pins. Each VDDIO must be tied to a valid operating voltage (1.71 V to 5.5 V), and must be less than or equal to VDDA. XRES. External reset pin. Active low with internal pull-up. Note 7. GPIOs with opamp outputs are not recommended for use with CapSense. |
