GENERAL DESCRIPTION
The P87LPC768 is a 20-pin single-chip microcontroller designed for
low pin count applications demanding high-integration, low cost
solutions over a wide range of performance requirements. A
member of the Philips low pin count family, the P87LPC768 offers
programmable oscillator configurations for high and low speed
crystals or RC operation, wide operating voltage range,
programmable port output configurations, selectable Schmitt trigger
inputs, LED drive outputs, and a built-in watchdog timer. The
P87LPC768 is based on an accelerated 80C51 processor
architecture that executes instructions at twice the rate of standard
80C51 devices.
FEATURES
An accelerated 80C51 CPU provides instruction cycle times of
300–600 ns for all instructions except multiply and divide when
executing at 20 MHz. Execution at up to 20 MHz when
VDD = 4.5 V to 6.0 V, 10 MHz when VDD = 2.7 V to 6.0 V.
Four-channel 10-bit Pulse Width Modulator
Four-channel multiplexed 8-bit A/D converter. Conversion time of
9.3
S at fosc = 20 MHz.
2.7 V to 6.0 V operating range for digital functions.
4 kbytes EPROM code memory.
128 byte RAM data memory.
32-byte customer code EPROM allows serialization of devices,
storage of setup parameters, etc.
Two 16-bit counter/timers. Each timer may be configured to toggle
a port output upon timer overflow.
Two analog comparators.
Full duplex UART.
I2C communication port.
Eight keypad interrupt inputs, plus two additional external interrupt
inputs.
Four interrupt priority levels.
Watchdog timer with separate on-chip oscillator, requiring no
external components. The watchdog timeout time is selectable
from 8 values.
Active low reset. On-chip power-on reset allows operation with no
external reset components.
Low voltage reset. One of two preset low voltage levels may be
selected to allow a graceful system shutdown when power fails.
May optionally be configured as an interrupt.
Oscillator Fail Detect. The watchdog timer has a separate fully
on-chip oscillator, allowing it to perform an oscillator fail detect
function.
Configurable on-chip oscillator with frequency range and RC
oscillator options (selected by user programmed EPROM bits).
The RC oscillator option allows operation with no external
oscillator components.
Programmable port output configuration options:
quasi-bidirectional, open drain, push-pull, input-only.
Selectable Schmitt trigger port inputs.
LED drive capability (20 mA) on all port pins.
Controlled slew rate port outputs to reduce EMI. Outputs have
approximately 10 ns minimum ramp times.
15 I/O pins minimum. Up to 18 I/O pins using on-chip oscillator
and reset options.
Only power and ground connections are required to operate the
P87LPC768 when fully on-chip oscillator and reset options are
selected.
Serial EPROM programming allows simple in-circuit production
coding. Two EPROM security bits prevent reading of sensitive
application programs.
Idle and Power Down reduced power modes. Improved wakeup
from Power Down mode (a low interrupt input starts execution).
Typical Power Down current is 1
A.
20-pin DIP and SO packages.
