GENERAL DESCRIPTION
The P80CL580; P83CL580 (hereafter generally referred to as P8xCL580) is manufactured in an advanced CMOS technology. The P8xCL580 has the same instruction set as the 80C51, consisting of over 100 instructions: 49 one- byte, 46 two-byte, and 16 three-byte. The device operates over a wide range of supply voltages and has low power consumption; there are two software selectable modes for power reduction: Idle and Power-down. For emulation purposes, the P85CL580 (piggy-back version) with 256 bytes of RAM is recommended.
FEATURES
• Full static 80C51 Central Processing Unit
• 8-bit CPU, ROM, RAM, I/O in a 56-lead VSO or 64-lead
QFP package
• 256 bytes on-chip RAM Data Memory
• 6 kbytes on-chip ROM Program Memory for P83CL580
• External memory expandable up to 128 kbytes: RAM up
to 64 kbytes and ROM up to 64 kbytes
• Five 8-bit ports; 40 I/O lines
• Three 16-bit Timers/Event counters
• On-chip oscillator suitable for RC, LC, quartz crystal or
ceramic resonator
• Fifteen source, fifteen vector, nested interrupt structure
with two priority levels
• Full duplex serial port (UART)
• I2C-bus interface for serial transfer on two lines
• Analog-to-digital converter (ADC) with Power-down
mode; 4 input channels and 8-bit ADC
• Pulse Width Modulated (PWM) output (8-bit resolution)
• Watchdog Timer
• Enhanced architecture with:
– non-page oriented instructions
– direct addressing
– four 8-byte RAM register banks
– stack depth limited only by available internal RAM
(maximum 256 bytes)
– multiply, divide, subtract and compare instructions
• Reduced power consumption through Power-down and
Idle modes
• Wake-up via external interrupts at Port 1
• Frequency range: 0 to 12 MHz. For ADC operation
minimum 250 kHz at 2.7 V
• Supply voltage: 2.5 to 6.0 V
• Very low current consumption:
typically 4.5 mA at 2.5 V and 8 MHz
• Operating ambient temperature range: −40 to +85 °C.APPLICATIONS
The P8xCL580 is an 8-bit general purpose microcontroller especially suited for cordless telephone and mobile communication applications. The P8xCL580 also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities.
