LPC436x

32-bit ARM Cortex-M4/M0 microcontroller

[3]

5 V tolerant pad with 15 ns glitch filter (5 V tolerant if VDDIO present; if VDDIO not present, do not exceed 3.6 V); provides digital I/O

functions with TTL levels, and hysteresis; high drive strength.

[4]

5 V tolerant pad with 15 ns glitch filter (5 V tolerant if VDDIO present; if VDDIO not present, do not exceed 3.6 V); provides high-speed

digital I/O functions with TTL levels and hysteresis.

[5]

5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input or output (5 V tolerant if VDDIO present;

if VDDIO not present, do not exceed 3.6 V). When configured as a ADC input or DAC output, the pin is not 5 V tolerant and the digital

section of the pad must be disabled by setting the pin to an input function and disabling the pull-up resistor through the pin’s SFSP

[6]

5 V tolerant transparent analog pad.

[7]

For maximum load CL = 6.5 F and maximum resistance Rpd = 80 k, the VBUS signal takes about 2 s to fall from VBUS = 5 V to VBUS

= 0.2 V when it is no longer driven.

[8]

Transparent analog pad. Not 5 V tolerant.

[9]

Pad provides USB functions; 5 V tolerant if VDDIO present; if VDDIO not present, do not exceed 3.6 V. It is designed in accordance with

the USB specification, revision 2.0 (Full-speed and Low-speed mode only).

[10] Open-drain 5 V tolerant digital I/O pad, compatible with I2C-bus Fast Mode Plus specification. This pad requires an external pull-up to

provide output functionality. When power is switched off, this pin connected to the I2C-bus is floating and does not disturb the I2C lines.

[11] 5 V tolerant pad with 20 ns glitch filter; provides digital I/O functions with open-drain output and hysteresis.

[12] On the LQFP208, VPP is internally connected to VDDIO.

[13] On the LQFP208 package, VSSIO and VSS are connected to a common ground plane.
