Product data sheet Rev. 4 — 20 June 2011 10 of 73 NXP Semiconductors LPC1311/13/42/43 32-bit ARM Cortex-M3 microcontroller 6.2 Pin description Table 3. LPC1313/42/43 LQFP48 pin description table Symbol Pin Start logic input Type Reset state [1] Description RESET/PIO0_0 3[2] yes I I; PU RESET — External reset input with 20 ns glitch filter. A LOW-going pulse as short as 50 ns on this pin resets the device, causing I/O ports and peripherals to take on their default states, and processor execution to begin at address 0. I/O - PIO0_0 — General purpose digital input/output pin with 10 ns glitch filter. PIO0_1/CLKOUT/ CT32B0_MAT2/ USB_FTOGGLE 4[3] yes I/O I; PU PIO0_1 — General purpose digital input/output pin. A LOW level on this pin during reset starts the ISP command handler or the USB device enumeration (USB on LPC1342/43 only, see description of PIO0_3). O- CLKOUT — Clockout pin. O- CT32B0_MAT2 — Match output 2 for 32-bit timer 0. O- USB_FTOGGLE — USB 1 ms Start-of-Frame signal (LPC1342/43 only). PIO0_2/SSEL0/ CT16B0_CAP0 10[3] yes I/O I; PU PIO0_2 — General purpose digital input/output pin. I/O - SSEL0 — Slave select for SSP0. I- CT16B0_CAP0 — Capture input 0 for 16-bit timer 0. PIO0_3/USB_VBUS 14[3] yes I/O I; PU PIO0_3 — General purpose digital input/output pin. LPC1342/43 only: A LOW level on this pin during reset starts the ISP command handler, a HIGH level starts the USB device enumeration. I- USB_VBUS — Monitors the presence of USB bus power (LPC1342/43 only). PIO0_4/SCL 15[4] yes I/O I; IA PIO0_4 — General purpose digital input/output pin (open-drain). I/O - SCL — I2C-bus clock input/output (open-drain). High-current sink only if I2C Fast-mode Plus is selected in the I/O configuration register. PIO0_5/SDA 16[4] yes I/O I; IA PIO0_5 — General purpose digital input/output pin (open-drain). I/O - SDA — I2C-bus data input/output (open-drain). High-current sink only if I2C Fast-mode Plus is selected in the I/O configuration register. PIO0_6/ USB_CONNECT/ SCK0 22[3] yes I/O I; PU PIO0_6 — General purpose digital input/output pin. O- USB_CONNECT — Signal used to switch an external 1.5 k resistor under software control. Used with the SoftConnect USB feature (LPC1342/43 only). I/O - SCK0 — Serial clock for SSP0. PIO0_7/CTS 23[3] yes I/O I; PU PIO0_7 — General purpose digital input/output pin (high-current output driver). I- CTS — Clear To Send input for UART. PIO0_8/MISO0/ CT16B0_MAT0 27[3] yes I/O I; PU PIO0_8 — General purpose digital input/output pin. I/O - MISO0 — Master In Slave Out for SSP0. O- CT16B0_MAT0 — Match output 0 for 16-bit timer 0. |
