Digital Core Design has announced a new version of its DF6808 eight-bit MCU IP core, which is binary compatible with the industry-standard Motorola 68HC08.
The combination of DCD's architectural enhancements with highly sophisticated on-chip peripheral capabilities allow the new DF6808 to perform 45 million to 100 million instructions per second.
With support for up to 64 KB of data memory and up to 64 KB of program memory, the DF6808 includes a full-duplex UART and supports the asynchronous Serial Communication Interface (SCI) and the synchronous Serial Peripheral Interface (SPI).
The DF6808 is equipped with a variety of sophisticated safety functions, including a Computer Operating Properly (COP) watchdog system that protects against software failures and an illegal opcode detection circuit that provides a nonmaskable interrupt should an illegal opcode occur.
In order to conserve power, the DF6808 supports two software-controlled power-saving modes -- WAIT and STOP -- which make this core especially attractive for battery-powered applications.
