P89LPC932
8-bit microcontroller with accelerated two-clock 80C51 core
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.
