P89LPC924/925
8-bit microcontrollers with accelerated two-clock 80C51 core
4 kB/8 kB 3 V low-power Flash with 8-bit A/D converter
Rev. 03 — 15 December 2004
Product data
1. General description
www.DataSheet4U.com
The P89LPC924/925 are single-chip microcontrollers designed for applications
demanding high-integration, low cost solutions over a wide range of performance
requirements. The P89LPC924/925 is based on a high performance processor
architecture that executes instructions in two to four clocks, six times the rate of
standard 80C51 devices. Many system-level functions have been incorporated into
the P89LPC924/925 in order to reduce component count, board space, and system
cost.
2. Features
2.1 Principal features
s 4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable page
size, and single byte erase.
s 256-byte RAM data memory.
s Two 16-bit counter/timers. Each timer may be configured to toggle a port output
upon timer overflow or to become a PWM output.
s Real-Time clock that can also be used as a system timer.
s 4-input 8-bit multiplexed A/D converter/single DAC output. Two analog
comparators with selectable inputs and reference source.
s Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities.
s 400 kHz byte-wide I2C-bus communication port.
s Configurable on-chip oscillator with frequency range and RC oscillator options
(selected by user programmed Flash configuration bits). The RC oscillator (factory
calibrated to ±1 %) option allows operation without external oscillator
components. Oscillator options support frequencies from 20 kHz to the maximum
operating frequency of 18 MHz. The RC oscillator option is selectable and fine
tunable.
s 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
s 15 I/O pins minimum. Up to 18 I/O pins while using on-chip oscillator and reset
options.

I/O, I [1] Port 1: Port 1 is an 8-bit I/O port with a user-configurable output type, except for three
pins as noted below. During reset Port 1 latches are configured in the input only mode
with the internal pull-up disabled. The operation of the configurable Port 1 pins as inputs
and outputs depends upon the port configuration selected. Each of the configurable
port pins are programmed independently. Refer to Section 8.13.1 “Port configurations”
and Table 8 “DC electrical characteristics” for details. P1.2 - P1.3 are open drain when
used as outputs. P1.5 is input only.
All pins have Schmitt triggered inputs.

Port 1 also provides various special functions as described below:
I/O P1.0 — Port 1 bit 0.
O TXD — Transmitter output for the serial port.
11 I/O P1.1 — Port 1 bit 1.
I RXD — Receiver input for the serial port.
10 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 serial clock input/output.
9 I/O P1.3 — Port 1 bit 3 (open-drain when used as output).
I INT0 — External interrupt 0 input.
I/O SDA — I2C serial data input/output.
8 I/O P1.4 — Port 1 bit 4.
I INT1 — External interrupt 1 input.
4 I P1.5 — Port 1 bit 5 (input only).
I RST — External Reset input (if selected via FLASH configuration). 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. When using an oscillator
frequency above 12 MHz, the reset input function of P1.5 must be enabled. An
external circuit is required to hold the device in reset at power-up until VDD has
reached its specified level. When system power is removed VDD will fall below the
minimum specified operating voltage. When using an oscillator frequency above
12 MHz, in some applications, an external brownout detect circuit may be
required to hold the device in reset when VDD falls below the minimum specified
operating voltage.
3 I/O P1.6 — Port 1 bit 6.
2 I/O P1.7 — Port 1 bit 7.
