The NXP Semiconductors S87C654-5A44 is a single-chip 8-bit microcontroller manufactured using an advanced CMOS process. It is a derivative of the 80C51 microcontroller family, sharing the same instruction set. This device is suitable for general control systems and offers architectural enhancements.
The microcontroller includes 16KB of mask-programmable ROM for program storage and 256 bytes of volatile read/write data memory. It is equipped with four 8-bit I/O ports, two 16-bit timer/event counters identical to the 80C51 timers, a multi-source, two-priority-level, nested interrupt structure, an I2C interface, and a full-duplex UART. On-chip oscillator and timing circuits are also integrated.
For systems requiring additional capability, the 8XC654 can be expanded using standard TTL-compatible memories and logic. The device supports clock frequencies ranging from 3.5 to 24 MHz. It operates within an ambient temperature range of -40 to +125°C and is available in a PDIP package.
