EC000 CORE PROCESSOR USER’S MANUAL
1-1
SECTION 1
OVERVIEW
This document contains a summary of the use and operation of the SCM68000 micropro-
cessor core (also referred to as the EC000 core)1 and a detailed set of timing and electrical
specifications. Refer to the
M68000 8-/16-/32-Bit Microprocessor User’s Manual
(M68000UM/AD) for detailed information on the operation of the instruction set, addressing
modes, and bus architecture for this core.
The SCM68000 is a core implementation of the MC68000 32-bit microprocessor and is
designed to be used as part of the FlexCore Program. In the FlexCore program, high-volume
manufacturers can create their own integrated microprocessor containing a core processor,
such as the SCM68000, and their own proprietary technology. A FlexCore integrated pro-
cessor allows significant reductions in component count, power consumption, board space,
and cost while yielding much higher system reliability and performance.
The main features of the SCM68000 include:
Low-Power HCMOS Implementation Requires Only 15 mA at 3.3 V
32-Bit Performance for 16-Bit Applications—2.7 MIPS at 16 MHz
Statically Selectable 8-Bit or 16-Bit Data Bus Operation
32-Bit Address Bus Directly Addresses up to 4 Gbytes of Address Space
Static Operation Provides Almost Zero Power Consumption During Idle Periods
Sixteen General-Purpose 32-Bit Data and Address Registers
Fifty-Six Powerful Instruction Types That Support High-Level Programming Languages
Fourteen Addressing Modes and Five Main Data Types Allow Compact, Efficient Code
Seven Priority Level Interrupt Control
Special Core Interfacing Signals
Emulation Support Signals Including Pipeline Refill, Processor Status, and Interrupt
Pending Signals
Both 3.3-V and 5-V Operation
The SCM68000 has a statically selectable 8-bit or 16-bit data bus. The address bus is 32-
bits wide and may be used as either a 24-bit address bus as on the MC68000 microproces-
sors, or as a 32-bit address bus to fully support the internal architecture. The 32-bit address
1. The SCM68000 is the name of the Verilog model for the EC000 core. The remainder of this section
will refer to the EC000 core as only the SCM68000.
