IP CORE OVERVIEW This document contains a brief description of the D6802 core functionality. The D6802 is an 8-bit MCU IP Core. It is binary-compatible with the industry standard MC6802 8-bit microprocessor. Two software-controlled power-saving modes WAIT and HALT are available, to conserve additional power. These modes make the D6802 IP Core especially attractive for automotive and battery-driven applications. The D6802 is fully customizable - it is delivered in an exact configuration to meet user’s requirements. It includes fully automated test bench with complete set of tests, allowing easy package validation at each stage of SoC design flow. ● De-multiplexed Address/Data Bus, to allow easy connection to memory ● Two power saving modes: HALT, WAIT ● No internal reset generator or gated clock ● Scan test ready ● Technology independent HDL source code ● Core can be fully customized TM ● DoCD - Hardware On-Chip Debugger LICENSING Comprehensible and clearly defined licensing methods without royalty-per-chip fees make use of our IP Cores easy and simple. Single-Site license option – dedicated to small and middle sized companies, which run their business in one place. Multi-Site license option – dedicated to corporate customers, who operate at several locations. The licensed product can be used in selected company branches. In all cases the number of IP Core instantiations within a project and the number of manufactured chips are unlimited. The license is royalty-per-chip free. There are no restrictions regarding the time of use.

You can specify your own peripheral set (including listed above and the others) and request the core modifications. 3 900 6 000 9 000 * - 6 700 * - 6 700 * - 8 900 * - 8 900 16 000 TM UNITS SUMMARY Control Unit - Performs the core synchronization and data flow control. This module manages execution of all instructions. The Control Unit also manages HALT input pin events. Opcode Decoder - Performs an instruction opcode decoding and the control functions for all other blocks. ALU - Arithmetic Logic Unit performs the arithmetic and logic operations, during execution of an instruction. It contains accumulator (A, B), Condition Code Register (CCREG), Index register X and related logic, like arithmetic unit, logic unit, multiplier and divider. Bus Controller – Program Memory, Data Memory interface controls access into the program and data memories. It contains Program Counter (PC), Stack Pointer (SP) register, and related logic. Interrupt Controller - The interrupt requests may come from external pins (IRQ and NMI) as well as from particular peripherals. DoCD - Debug Unit – it’s a real-time hardware debugger, which provides debugging capability of a whole SoC system. Unlike other on-chip debuggers, DoCD™ provides non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller, including all registers, internal, external, program memories, all SFRs, including user defined peripherals. Hardware breakpoints can be set and controlled on program memory, internal and external data memories, as well as on SFRs. Hardware breakpoint is executed, if any write/read occurs at particular address, with cerTM tain data pattern or without pattern. The DoCD system includes three-wire interface and complete set of tools, to communicate and work with core in real time debugging. It is built as scalable unit and some features can be turned off by the user, to save silicon and reduce power consumption. When debugger is not used, it is automatically switched to power save mode. Finally, when debug option is no longer used, whole debugger is turned off. 2 Copyright © 1999-2016 DCD – Digital Core Design. All Rights Reserved.
