P89LPC930

P89LPC930/931 8-bit microcontrollers with two-clock 80C51 core 4 kB/8 kB 3 V Flash with 256-byte data RAM Rev. 04 — 06 January 2004 Product data 1. General description The P89LPC930/931 is a single-chip microcontroller designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements. The P89LPC930/931 is 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 P89LPC930/931 in order to reduce component count, board space, and system cost. 2. Features s A high performance 80C51 CPU provides instruction cycle times of 167-333 ns for all instructions except multiply and divide when executing at 12 MHz. This is 6 times the performance of the standard 80C51 running at the same clock frequency. A lower clock frequency for the same performance results in power savings and reduced EMI. s 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V). s 4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size. s Byte-erase allowing code memory to be used for data storage. s Flash program operation completes in 2 ms. s Flash erase operation completes in 2 ms. s 256-byte RAM data memory. s Two 16-bit counter/timers. Each timer may be configured to toggle a port output upon timer overflow or to become a PWM output. s Real-Time clock that c...
