Serial Flash In-Circuit Programming (ICP) allows simple production coding with
commercial EPROM programmers. Flash security bits prevent reading of sensitive
application programs.
Watchdog timer with separate on-chip oscillator, requiring no external components.
The Watchdog prescaler is selectable from 8 values.
Low voltage brownout detect allows a graceful system shutdown when power fails.
May optionally be configured as an interrupt.
Idle and two different power-down reduced power modes. Improved wake-up from
Power-down mode (a LOW interrupt input starts execution). Typical power-down
current is 1 A (total power-down with voltage comparators disabled).
Active-LOW reset. On-chip power-on reset allows operation without external reset
components. A reset counter and reset glitch suppression circuitry prevent spurious
and incomplete resets. A software reset function is also available.
Programmable port output configuration options: quasi-bidirectional, open drain,
push-pull, input-only.
Port ‘input pattern match’ detect. Port 0 may generate an interrupt when the value of
the pins match or do not match a programmable pattern.
LED drive capability (20 mA) on all port pins. A maximum limit is specified for the
entire chip.
Controlled slew rate port outputs to reduce EMI. Outputs have approximately 10 ns
minimum ramp times.
Only power and ground connections are required to operate the P89LPC915/916/917
when internal reset option is selected.
Four interrupt priority levels.
Five (P89LPC916), six (P89LPC915), or seven (P89LPC917) keypad interrupt inputs.
Second data pointer.
Schmitt trigger port inputs.
Emulation support.
