2 / 60 page Philips Semiconductors P89LPC932 8-bit microcontroller with accelerated two-clock 80C51 core Product data Rev. 04 — 06 January 2004 2 of 60 9397 750 12379 © Koninklijke Philips Electronics N.V. 2004. All rights reserved. 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. |
