8-bit FAST Microcontrollers Family

The DF6808 is an advanced, 8-bit, MCU IP Core with highly sophisticated, on-chip peripheral capabilities. The DF6808 soft core is binary-compatible with the industry standard Motorola 68HC08 8-bit microcontroller. It can achieve a performance of 45 – 100 million instructions per second. The DF6808 has a FAST architecture that is 3.2 times faster comparing to the original implementation. In the standard configuration the core has major peripheral functions integrated on-chip. The DF6808 Microcontroller Core contains a full-duplex UART – Asynchronous Serial Communication Interface (SCI) and Synchronous Serial Peripheral Interface (SPI). The main 16-bit, free-running timer system has two input capture lines and two output-compare lines. Self-monitoring circuitry is included on-chip, to protect against system errors. The Computer Operating Properly (COP) watchdog system protects against software failures. An illegal opcode detection circuit provides a non-maskable interrupt if illegal opcode is detected. Two software-controlled power-saving modes – WAIT and STOP are available to preserve additional power. These modes make the DF6808 IP Core especially attractive for automotive and battery-driven applications. The DF6808 is fully customizable – it is delivered in the exact configuration to meet your requirements. There is no need to pay extra for unused features and wasted silicon. It includes fully automated test bench with complete set of tests, allowing easy package validation, at each stage of SoC design flow. Each DCD’s DF68XX Core has a built-in support for a proprietary Hardware Debug System called DoCD™. It’s a real-time hardware debugger which provides debugging capability of a whole System-on-Chip (SoC). Unlike the other on-chip debuggers the DoCD™ enables non-intrusive debugging of a running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, SFRs, including user defined peripherals, data and program memories.
