LPC1311/13/42/43

32-bit ARM Cortex-M3 microcontroller

[1]

Typical ratings are not guaranteed. The values listed are at room temperature (25

°C), nominal supply voltages.

[2]

Tie together VDD(3V3) and VDD(IO) externally. If separate supplies are used for VDD(3V3) and VDD(IO), ensure that the voltage difference

between both supplies is smaller than or equal to 0.5 V.

[3]

IRC enabled; system oscillator disabled; system PLL disabled.

[4]

BOD disabled.

[5]

All peripherals disabled in the AHBCLKCTRL register. Peripheral clocks to UART, SSP, trace clock, and SysTick timer disabled in the

syscon block.

[6]

IRC disabled; system oscillator enabled; system PLL enabled.

[7]

All oscillators and analog blocks turned off in the PDSLEEPCFG register; PDSLEEPCFG = 0xFFFF FFFF

[8]

WAKEUP pin pulled HIGH externally.

[9]

For LPC134x: USB_DP and USB_DM pulled LOW externally.

[10] Including voltage on outputs in 3-state mode.

[11] VDD(3V3) and VDD(IO) supply voltages must be present.

[12] 3-state outputs go into 3-state mode when VDD(IO) is grounded.

[13] Accounts for 100 mV voltage drop in all supply lines.

[14] Allowed as long as the current limit does not exceed the maximum current allowed by the device.

[15] To VSS.

[16] Includes external resistors of 33

Ω± 1 % on USB_DP and USB_DM.
