Product data sheet Rev. 06 — 20 June 2005 7 of 75 Philips Semiconductors P89LPC933/934/935/936 8-bit microcontroller with accelerated two-clock 80C51 core 6.2 Pin description Table 4: Pin description Symbol Pin Type Description TSSOP28, PLCC28 HVQFN28 P0.0 to P0.7 I/O Port 0: Port 0 is an 8-bit I/O port with a user-configurable output type. During reset Port 0 latches are configured in the input only mode with the internal pull-up disabled. The operation of Port 0 pins as inputs and outputs depends upon the port configuration selected. Each port pin is configured independently. Refer to Section 8.13.1 “Port configurations” and Table 11 “Static characteristics” for details. The Keypad Interrupt feature operates with Port 0 pins. All pins have Schmitt trigger inputs. Port 0 also provides various special functions as described below: P0.0/CMP2/ KBI0/AD01 3 27 I/O P0.0 — Port 0 bit 0. O CMP2 — Comparator 2 output. I KBI0 — Keyboard input 0. I AD01 — ADC0 channel 1 analog input. (P89LPC935/936) P0.1/CIN2B/ KBI1/AD10 26 22 I/O P0.1 — Port 0 bit 1. I CIN2B — Comparator 2 positive input B. I KBI1 — Keyboard input 1. I AD10 — ADC1 channel 0 analog input. P0.2/CIN2A/ KBI2/AD11 25 21 I/O P0.2 — Port 0 bit 2. I CIN2A — Comparator 2 positive input A. I KBI2 — Keyboard input 2. I AD11 — ADC1 channel 1 analog input. P0.3/CIN1B/ KBI3/AD12 24 20 I/O P0.3 — Port 0 bit 3. I CIN1B — Comparator 1 positive input B. I KBI3 — Keyboard input 3. I AD12 — ADC1 channel 2 analog input. P0.4/CIN1A/ KBI4/DAC1 23 19 I/O P0.4 — Port 0 bit 4. I CIN1A — Comparator 1 positive input A. I KBI4 — Keyboard input 4. O DAC1 — Digital-to-analog converter output 1. I AD13 — ADC1 channel 3 analog input. P0.5/ CMPREF/ KBI5 22 18 I/O P0.5 — Port 0 bit 5. I CMPREF — Comparator reference (negative) input. I KBI5 — Keyboard input 5. P0.6/CMP1/ KBI6 20 16 I/O P0.6 — Port 0 bit 6. O CMP1 — Comparator 1 output. I KBI6 — Keyboard input 6. P0.7/T1/ KBI7 19 15 I/O P0.7 — Port 0 bit 7. I/O T1 — Timer/counter 1 external count input or overflow output. I KBI7 — Keyboard input 7. |
