6、 Software reset Power-on detect reset ADC charge pump disable ONCE mode ADC active in Idle modeDESCRIPTIONThe 87C552 Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 87C552 has the same instruction set as the 8

7、0C51.The 87C552 contains a 8k 8 non-volatile EPROM, a 256 8 read/write data memory, five 8-bit I/O ports, one 8-bit input port, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and compare latches, a 15-source, four-priority-level,

8、 nested interrupt structure, an 8-input ADC, a dual DAC pulse width modulated interface, two serial interfaces (UART and I2C-bus), a “watchdog” timer and on-chip oscillator and timing circuits. For systems that require extra capability, the 8xC552 can be expanded using standard TTL compatible memori

9、es and logic.In addition, the 8xC552 has two software selectable modes of power reductionidle mode and power-down mode. The idle mode freezes the CPU while allowing the RAM, timers, serial ports, and interrupt system to continue functioning. Optionally, the ADC can be operated in Idle mode. The powe

10、r-down mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative.The device also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set consists of over 100 instruc

11、tions: 49 one-byte, 45 two-byte, and 17 three-byte. With a 16MHz crystal, 58% of the instructions are executed in 0.75ms and 40% in 1.5ms. Multiply and divide instructions require 3ms.2003 Apr 012853-2410 29338Philips SemiconductorsProduct data80C51 8-bit microcontroller8K/256 OTP, 8 channel 10 bit
