P89LPC9151/9161/9171

8-bit microcontroller with 8-bit ADC

[1]

Input/output for P1.0 to P1.4. Input for P1.5.

P1.0/TXD

I/O

P1.0 — Port 1 bit 0.

TXD — Transmitter output for serial port.

P1.1/RXD

I/O

P1.1 — Port 1 bit 1.

RXD — Receiver input for serial port.

P1.2/T0/SCL

I/O

P1.2 — Port 1 bit 2 (open-drain when used as output).

I/O

T0 — Timer/counter 0 external count input or overflow output (open-drain when

used as output).

I/O

SCL — I2C-bus serial clock input/output.

P1.3/INT0/SDA

I/O

P1.3 — Port 1 bit 3 (open-drain when used as output).

INT0 — External interrupt 0 input.

I/O

SDA — I2C-bus serial data input/output.

P1.4/INT1

I/O

P1.4 — Port 1 bit 4. High current source.

INT1 — External interrupt 1 input.

P1.5/RST

P1.5 — Port 1 bit 5 (input only).

RST — External Reset input during power-on or if selected via UCFG1. When

functioning as a reset input, a LOW on this pin resets the microcontroller, causing

I/O ports and peripherals to take on their default states, and the processor begins

execution at address 0. Also used during a power-on sequence to force ISP

mode.

VSS

Ground: 0 V reference.

VDD

Power supply: This is the power supply voltage for normal operation as well as

Idle and Power-down modes.
