Description
The Philips 8XC51/31 designed as a high-performance static 80C51 design fabricated with Philips high-density CMOS technology. The 80C51 can work with a voltage range of 2.7V to 5.5V. The 80C31 has a 4k 8 ROM, 128 8 RAM, 32 I/O lines, three 16-bit counter/timers, and a hierarchical interrupt mechanism with six sources and four priority levels. There’s also an on-chip oscillator and clock circuit, as well as a serial I/O port for multi-processor communications, I/O extension, or full duplex UART.
Furthermore, the 80C31 is equipped with static logic for operating at low frequencies and offers two software configurable power saving modes. The CPU is turned off in Idle Mode, although RAM, timers/counters, serial port, and interrupt system continue to work. The Power-down mode, on the other hand, saves the RAM data but freezes the oscillator. All other chip functions are disabled until the next external interrupt or hardware reset. It is appropriate for battery-operated applications because of these two properties. The lack of an in-built ADC and support for the SPI and I2C protocols are the microcontroller’s biggest flaws. The clock can be stopped without losing user data since the design is static. The execution then restarted from where the clock had been paused.
Applications
- Multiple DIY Projects
- Very good choice if you are learning ATmel
- Projects requiring Multiple I/O interfaces and communications
- Replacement for Arduino Module
- Ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
