Mixed-Signal MCU Value Proposition
Industry Leading
Functional Density
21st Century technology extends the life of
your 8-bit system, reduces system costs
and enables new features
♦ Smallest
¾ Highest functional density in packages as
small as 3 x 3 mm
♦ Fastest
¾ Pipelined, patented 100 MIPS 8051 core
♦ Best analog
¾ Up to 24-bit ADC, up to 12-bit DAC, up to
0.5% precision oscillator, comparators, onchip temperature sensor
3
Portable Application Designer Challenges
♦ Consumers demand longer battery life
¾ Impact: Designers must maximize power
efficiency
♦ Consumers demand lower cost
¾ Impact: Designers must revolutionize
systems to realize cost efficiency
♦ Consumers demand more portability
¾ Impact: Each components must maximize
functionality to reduce the overall board
space

♦ C8051F9xx with integrated LDO regulator
¾ Provides a constant output voltage of 1.7 V independent of battery voltage
¾ Provides a constant current independent of battery voltage
¾ Result is lower power over all operating voltages,
maximizing battery life
7
One-Cell Mode: DC-DC Converter Advantage
♦ C8051F9xx integrates a high-efficiency dc-dc boost converter
¾ Provides MCU core with 1.7 V supply
¾ Programmable output voltage from 1.8 - 3.3 V
¾ Can supply up to 65 mW total power to external devices
ƒEnables a true one-cell system solution for smaller
form factors
8
The Multi-Chip Disadvantage
+
=
♦ Two chip MCU and dc-dc converter solution:
¾ Occupies more board space
¾ Cost is higher (typically ~$1.00 - $3.00)
¾ Low current sleep mode is not possible because dc-dc converter
needs to operate continuously (typically >20 µA)
¾ Most stand-alone converters have poor efficiency at MCU-level load
currents (50 - 70%)
¾ Overall power efficiency of the two-chip solution is much lower
