MC68HC705K1CP Description

Short technical summary and product information.

The MC68HC705K1CP is a microcontroller manufactured by ON Semiconductor, based on the popular M68HC05 CPU core. This component is designed for embedded applications and features 504 bytes of erasable, programmable read-only memory (EPROM) and 32 bytes of user random-access memory (RAM).

 

Key features include memory-mapped input/output (I/O) registers, 10 bidirectional I/O pins with software programmable pulldown devices, and support for maskable external interrupts. The device operates in a fully static manner with no minimum clock speed requirement and includes an on-chip oscillator with options for crystal, ceramic resonator, or RC configurations. It also incorporates a Computer Operating Properly (COP) watchdog timer and a 15-bit multifunction timer with a real-time interrupt circuit.

 

Power-saving modes such as stop, wait, halt, and data-retention are supported. The microcontroller includes an 8x8 unsigned multiply instruction and features for illegal address reset and low-voltage reset, enhancing system reliability. The MC68HC705K1CP is suitable for various embedded control tasks where its specific memory and I/O capabilities meet design requirements.
