MC68EC020FG25 Description
The MC68EC020FG25 is an economical high-performance embedded microprocessor based on the MC68020 and has been designed specifically to suit the needs of the embedded microprocessor market. This device belongs to the M68000 family of microprocessors from Motorola. With the use of VLSI technology, the MC68020 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes. The main differences in the MC68EC020FG25 and the MC68020 are that the MC68EC020FG has a 24-bit address bus and does not implement the following signals such as ECS, OCS, DBEN, IPEND, and BGACK.
Pin Configuration of MC68EC020FG25
The VCC and GND pins are separated into four groups to provide individual power supply connections for the address bus buffers, data bus buffers, and all other output buffers and internal logic. It is recommended that all pins be connected to power and ground as indicated. No Connection pins are reserved by Motorola for future use and should have no external connection.
Specifications and features of MC68EC020FG25
The main features of the MC68EC020FG25 is as follows:
● Object-Code compatible with earlier M68000 Microprocessors
● Addressing Mode extensions for improved support of high-level languages
● New bit field data type fastened bit-oriented applications (e.g : Video Graphics)
● An on-chip instruction cache for faster execution of instructions
● Pipelined Architecture with High Degree of Internal Parallelism Letting Multiple Instructions to Be Executed Concurrently
● High-Performance Asynchronous Bus which is Non-multiplexed and Full 32 Bits
● Dynamic Bus Sizing Efficiently Supports 8-/16-Bit Memories and Peripherals
● Full Support of Virtual Machine and Virtual Memory.
● Presence of sixteen 32-Bit General-Purpose Data and Address Registers
● Presence of eighteen Addressing Modes and Seven Data Types
● 16-Mbyte Direct Addressing Range for the MC68EC020 FG25
● Selection of the processor speeds for the MCEC68020FG25: 16.67 MHz and 25 MHz
● Operating temperature of 0 to +105 Celsius degrees.
Working principle of MC68EC020FG25
The MC68EC020FG25 is object-code compatible with earlier members of the M68000 family and has the added features of new addressing modes in support of high-level languages, an on-chip instruction cache, and a flexible coprocessor interface having the full IEEE floating-point support. The internal operations of the MC68EC020FG25 microprocessor operate in parallel, allowing multiple instructions to be executed concurrently.
The processor supports a dynamic bus sizing mechanism that permits the processor to transfer operands to or from external devices while automatically determining device port size on a cycle-by-cycle basis. The dynamic bus interface permits access to devices of differing data bus widths, in addition to eliminating all data alignment restrictions. The asynchronous bus structure of the device uses a non-multiplexed bus with 24 bits of address and 24 bits of data. The device has a maximum clock frequency of 25 MHz and it operates in a supply voltage of 5v.
