Product data
Low voltage reset (Brownout detect) allows 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 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.
Programmable port output configuration options:
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.
Second data pointer.
Schmitt trigger port inputs.
LED drive capability (20 mA) on all port pins. Maximum combined I/O current of
100 mA.
Controlled slew rate port outputs to reduce EMI. Outputs have approximately
10 ns minimum ramp times.
23 I/O pins minimum (28-pin package). Up to 26 I/O pins while using on-chip
oscillator and reset options.
Only power and ground connections are required to operate the P89LPC930/931
using on-chip oscillator and on-chip reset options.
Serial Flash programming allows in-circuit production coding. Flash security bits
prevent reading of sensitive programs.
code in a running application.
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).
28-pin TSSOP package.
Emulation support.
In-Application Programming of the Flash code memory. This allows changing the
