DESCRIPTION

The 80CL410/83CL410 (hereafter generically referred to as 8XCL410) is manufactured in an advanced CMOS process that allows the part to operate at supply voltages down to 1.8V and oscillator frequencies down to DC. The 8XCL410 has the same instruction set as the 80C51.

FEATURES

• Single supply voltage 1.8V to 6.0V
• Frequency from DC to 12MHz
• 80C51 based architecture
– 4k × 8 ROM (64k external)
– 128 × 8 RAM (64k external)
– Four 8-bit I/O ports
– Two 16-bit timer/counters
– A thirteen-source, two-level, nested priority interrupt structure
– 10 external interrupts
• Fully static 80C51 CPU
• I2C Serial Interface
• Two power control modes
– Idle mode
– Power-down mode – can be terminated by reset or external interrupt
• Wake-up via external interrupts at port 1
• Single supply voltage 1.8V to 6.0V
• Frequency range of DC to 12MHz
• On-chip oscillator (quartz crystal, ceramic resonator, RC, LC)
• Very low power consumption
• Operating temperature range: –40 to +85°C
