s Oscillator Fail Detect. The Watchdog timer has a separate fully on-chip oscillator

allowing it to perform an oscillator fail detect function.

s Conﬁgurable on-chip oscillator with frequency range and RC oscillator options

(selected by user programmed Flash conﬁguration bits). The RC oscillator option

allows operation without external oscillator components. Oscillator options

support frequencies from 20 kHz to the maximum operating frequency of 12 MHz.

The RC oscillator option is selectable and ﬁne tunable.

s Programmable port output conﬁguration options:

x quasi-bidirectional,

x open drain,

x push-pull,

x input-only.

s 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.

s Second data pointer.

s Schmitt trigger port inputs.

s LED drive capability (20 mA) on all port pins. A maximum limit is speciﬁed for the

entire chip.

s Controlled slew rate port outputs to reduce EMI. Outputs have approximately

10 ns minimum ramp times.

s 23 I/O pins minimum (28-pin package). Up to 26 I/O pins while using on-chip

oscillator and reset options.

s Only power and ground connections are required to operate the P89LPC932

when on-chip oscillator and reset options are selected.

s Serial Flash programming allows simple in-circuit production coding. Flash

security bits prevent reading of sensitive application programs.

s In-Application Programming of the Flash code memory. This allows changing the

code in a running application.

s 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

µA (total Power-down with voltage comparators disabled).

s 28-pin PLCC, TSSOP, and HVQFN packages.

s Emulation support.
