Product Summary

The P89LPC934F is a single-chip microcontroller, available in low cost packages, based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices. Many system-level functions have been incorporated into the P89LPC934F in order to reduce component count, board space, and system cost.

Parametrics

P89LPC934F absolute maximum ratings: (1)Tamb(bias), operating bias ambient temperature: -55 to +125℃; (2)Tstg, storage temperature range: -65 to +150℃; (3)IOH(I/O), HIGH-level output current per I/O pin: 20 mA; (4)IOL(I/O), LOW-level output current per I/O pin: 20 mA; (5)II/O(tot)(max) maximum total I/O current: 100 mA; (6)Vn, voltage on any pin (except VSS) with respect to VDD: - 3.5 V; (7)Ptot(pack), total power dissipation: 1.5 W.

Features

P89LPC934F features: (1)Four interrupt priority levels; (2)Eight keypad interrupt inputs, plus two additional external interrupt inputs; (3)Schmitt trigger port inputs; (4)Second data pointer; (5)Emulation support; (6)4 kB/8 kB/16 kB byte-erasable flash code memory organized into 1 kB/2 kB sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage; (7)256-byte RAM data memory. Both the P89LPC935 and P89LPC936 also include a 512-byte auxiliary on-chip RAM; (8)512-byte customer data EEPROM on chip allows serialization of devices, storage of setup parameters, etc. (P89LPC935/936); (9)Dual 4-input multiplexed 8-bit A/D converters/DAC outputs (P89LPC935/936, single A/D on P89LPC933/934).Two analog comparators with selectable inputs and reference source; (10)Two 16-bit counter/timers (each may be configured to toggle a port output upon timer overflow or to become a PWM output) and a 23-bit system timer that can also be used as an RTC.
