GENERAL DESCRIPTION
The P87LPC760 is a 14-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 P87LPC760 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
P87LPC760 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
2.7 V to 6.0 V operating range for digital functions
1 kbyte 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. One timer may be configured to toggle
a port output upon timer overflow
One analog comparator
Full duplex UART
I2C communication port
Four keypad interrupt inputs, plus one additional external interrupt
input
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
Nine I/O pins minimum. Up to 12 I/O pins using on-chip oscillator
and reset options
Only power and ground connections are required to operate the
P87LPC760 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 mA
