P89C60X2BA

The Philips P89C60X2BA is a high-performance static 80C51 microcontroller manufactured using an advanced CMOS process. It features 64KB of non-volatile Flash program memory that is programmable in parallel or In-System Programmable (ISP) via a boot loader. This microcontroller family supports both 12-clock and 6-clock operation.

The P89C60X2 variant includes 512 bytes of RAM, while the P89C61X2 offers 1024 bytes of RAM. Both models provide 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, and a serial I/O port for multi-processor communications, I/O expansion, or full-duplex UART. They also include on-chip oscillator and clock circuits.

Designed for static operation, these devices can function at frequencies down to zero. They incorporate two software-selectable power reduction modes: idle mode, which freezes the CPU while allowing RAM, timers, serial port, and interrupt system to continue functioning, and power-down mode, which saves RAM contents but freezes the oscillator. The static design allows the clock to be stopped and execution resumed from the point of interruption without loss of user data.
