Microcontroller vs. Microprocessors
1.
2.
3.
CPU for Computers
No RAM, ROM, I/O on CPU chip itself
Example：Intel’s x86, Motorola’s 680x0
1.
2.
3.
A smaller computer
On-chip RAM, ROM, I/O ports...
Example：Motorola’s 6811,
Intel’s 8051, Zilog’s Z8 and PIC
Microcontroller vs. Microprocessors
Microprocessor
1.
CPU is stand-alone, RAM,
ROM, I/O, timer are separate
2.
designer can decide on the
amount of ROM, RAM and
I/O ports.
3.
expansive
4.
versatility
5.
general-purpose
Microcontroller
1. CPU, RAM, ROM, I/O and
timer are all on a single chip
2. fix amount of on-chip ROM,
RAM, I/O ports
3. for applications in which cost,
power and space are critical
4. single-purpose
uP vs. uC – cont.
Applications
– uCs are suitable to
control of I/O
devices in designs
requiring a minimum
component
– uPs are suitable to
processing
information in
computer systems.
uP vs. uC – cont.
uC is easy to use and design.
– Only single chip can be a complete system
– interfacing to other devices,
• for example, motors, displays, sensors, and
communicate with PC.
In contrast, similar system that builds from
uP would require a lot of additional units,
– such as RAM, UART, I/O , TIMER and etc.
Embedded Computing Systems
Use a microprocessor or microcontroller to do one
task only
– Printer
PC used for any number of applications
– Word processor, print-server, bank teller terminal,
video game player, network server, internet terminal
PC contains or is connected to various embedded
products
– Keyboard, printer, modem, disk controller, sound card,
CD-ROM driver, mouse
X86 PC embedded applications
High-end Embedded Processor
Microcontroller types
•
The predominant family of microcontrollers are 8-bit
•
most manufacturers provide a family of devices
•
The Philips products are identified bythe numbering system:
8XCXXX
•
•
•
•
0 for a ROMless device
3 for a device with ROM
7 for a device with EPROM/OTP (one time programmable)
9 or a device with FEEPROM (flash).
