21 / 170 page  4.2001; Rev. 1.3 CYGNAL Integrated Products, Inc. 2001 Page 21 C8051F000/1/2/5/6/7 C8051F010/1/2/5/6/7 PRELIMINARY 4. PINOUT AND PACKAGE DEFINITIONS Table 4.1. Pin Definitions Pin Numbers Name F000 F010 F001 F011 F002 F012 Type Description VDD 31, 40, 62 23, 32 18, 20 Digital Voltage Supply. DGND 30, 41, 61 22, 33, 27, 19 17, 21 Digital Ground. AV+ 16, 17 13, 43 9, 29 Positive Analog Voltage Supply. AGND 5, 15 44, 12 8, 30 Analog Ground. TCK 22 18 14 DIn JTAG Test Clock with internal pull-up. TMS 21 17 13 DIn JTAG Test-Mode Select with internal pull-up. TDI 28 20 15 DIn JTAG Test Data Input with internal pull-up. TDI is latched on a rising edge of TCK. TDO 29 21 16 D Out JTAG Test Data Output with internal pull-up. Data is shifted out on TDO on the falling edge of TCK. TDO output is a tri-state driver. XTAL1 18 14 10 AIn Crystal Input. This pin is the return for the internal oscillator circuit for a crystal or ceramic resonator. For a precision internal clock, connect a crystal or ceramic resonator from XTAL1 to XTAL2. If overdriven by an external CMOS clock, this becomes the system clock. XTAL2 19 15 11 A Out Crystal Output. This pin is the excitation driver for a crystal or ceramic resonator. /RST 20 16 12 D I/O Chip Reset. Open-drain output of internal Voltage Supply monitor. Is driven low when VDD is < 2.7V. An external source can force a system reset by driving this pin low. VREF 6 3 3 A I/O Voltage Reference. When configured as an input, this pin is the voltage reference for the MCU. Otherwise, the internal reference drives this pin. CP0+ 4 2 2 AIn Comparator 0 Non-Inverting Input. CP0- 3 1 1 AIn Comparator 0 Inverting Input. CP1+ 2 45 AIn Comparator 1 Non-Inverting Input. CP1- 1 46 AIn Comparator 1 Inverting Input. DAC0 64 48 32 A Out Digital to Analog Converter Output 0. The DAC0 voltage output. (See Section 7 DAC Specification for complete description). DAC1 63 47 31 A Out Digital to Analog Converter Output 1. The DAC1 voltage output. (See Section 7 DAC Specification for complete description). AIN0 7 4 4 AIn Analog Mux Channel Input 0. (See ADC Specification for complete description). AIN1 8 5 5 AIn Analog Mux Channel Input 1. (See ADC Specification for complete description). AIN2 9 6 6 AIn Analog Mux Channel Input 2. (See ADC Specification for complete description). AIN3 10 7 7 AIn Analog Mux Channel Input 3. (See ADC Specification for complete description). AIN4 11 8 AIn Analog Mux Channel Input 4. (See ADC Specification for complete description). AIN5 12 9 AIn Analog Mux Channel Input 5. (See ADC Specification for complete description). AIN6 13 10 AIn Analog Mux Channel Input 6. (See ADC Specification for complete description). |
