l
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.
l
Oscillator Fail Detect. The watchdog timer has a separate fully on-chip oscillator, allowing it to perform an oscillator fail detect
function.
l
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.
l
Programmable port output configuration options: quasi-bidirectional, open drain, push-pull, input-only.
l
Selectable Schmitt trigger port inputs.
l
LED drive capability (20 mA) on all port pins.
l
Controlled slew rate port outputs to reduce EMI. Outputs have approximately 10 ns minimum ramp times.
l
15 I/O pins minimum. Up to 18 I/O pins using on-chip oscillator and reset options.
l
Only power and ground connections are required to operate the 87LPC768 when fully on-chip oscillator and reset options are
selected.
l
Serial EPROM programming allows simple in-circuit production coding. Two EPROM security bits prevent reading of sensitive
application programs.
l
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.
l
20-pin DIP and SO packages.
