Select a secure architecture
Select a simple solution
The C8051 is based on a Harvard
architecture, allowing it to only execute code
fetched from program memory, and allows
locking of program memory to prevent
unauthorized examination. These are two
advantages in the C8051 hardware that
protects a product from security attacks.
The C8051 microcontroller is ideal for
processing 8-bit data that comes from
port I/O or sensors inputs. A great many
applications don’t require complex
mathematics processing, and benefit
significantly from the code density
advantages of an 8-bit processor when
not tasked with 16-bit or 32-bit
mathematics. Human interface functions,
sensor interface, and distributed processing
functions are examples that easily benefit
from the simplicity of the C8051 solutions.
Select a low latency system
Variations in interrupt response time can
cause adverse effects in some applications,
causing, for example, audio distortion or
motor noise and vibration. With the C8051
it’s easy to work “close to the metal” and
have full control over the entire system.

Despite strong media coverage
of the rapid expansion of the
ARM ecosystem, the largest
ecosystem in MCUs still exists
around the mature and tiny 8051
MCU architecture.

capacitive sensing.
Crystal-less Operation
Fast and Efficient Processor Core
Precision internal oscillators with speeds up 50
MHz support full speed processor and peripheral
operation and reduce PCB area requirements and
BOM cost.
With up to 100 MIPS peak throughput, the C8051
microcontrollers provide an economical solution
that satisfies the performance needs of embedded
applications.
Fast and Efficient Digital
Peripherals
No Performance Compromises
C8051 microcontrollers provide robust oscillators,
core, I/O and analog and digital peripherals with
guaranteed performance over voltage and
temperature range.
Efficient peripherals reduces processor overhead
and include high performance timers and
PWMs for high-resolution and high-speed serial
peripherals to optimize throughput.
Highly Integrated USB
Free software libraries simplify development,
and crystal-less operation, onboard voltage
regulator, and internal memory reduces PCB
area and BOM cost.
Ultra Low Power
2µs
150uA/
MHz
50nA
Time
Ultra low standby with brown out detection, fast wake
times, and low active current along with buck and
boost converter options offer long battery lifetime.
Digital Crossbar and
Analog Multiplexer
Simplicity Studio™ Software and
Crossbar Configurator
Silicon Labs’ patented crossbar technology
enables maximum flexibility and unparalleled
ease of development, allowing designers to
select peripherals without pinout conflicts.
Automatic configuration code generation, free
unlimited code size Keil compiler, profile tools,
easily updated support packages, software and
documentation, all at your finger tips.
