Product Summary
The AR8327-AL1A is a high performance CMOS single chip 8-bit Microcontroller. The AR8327-AL1A retains all the features of the 80C52 with extended ROM capacity (16K bytes), 256 bytes of RAM, 32 I/O lines, a 6-source 2-level interrupts, a full duplex serial port, an on-chip oscillator and clock circuits, three 16 bit timers with extra features: 32 bit timer and watchdog functions. Timer 0 and 1 can be configured by program to implement a 32 bit timer. The watchdog function can be activated either with timer 0 or timer 1 or both together (32 bit timer).
