Introduction The P89LPC9301/931A1 are single-chip microcontrollers designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements. The P89LPC9301/931A1 are 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 P89LPC9301/931A1 in order to reduce component count, board space, and system cost. 1.1 Pin configuration P2.0 P2.1 P0.0/CMP2/KBI0 P1.7 P1.6 P1.5/RST VSS P3.1/XTAL1 P3.0/XTAL2/CLKOUT 1 2 3 4 5 6 7 8 9 28 P2.7 27 P2.6 26 P0.1/CIN2B/KBI1 25 P0.2/CIN2A/KBI2 24 P0.3/CIN1B/KBI3 23 P0.4/CIN1A/KBI4 22 P0.5/CMPREF/KBI5 21 VDD 20 P0.6/CMP1/KBI6 19 P0.7/T1/KBI7 18 P1.0/TXD 17 P1.1/RXD 16 P2.5/S...
