Smart grid market landscape

►Smart Grid* – “A smart grid enables two-way communication and digital control throughout the electricity delivery infrastructure.”

►According to the United States Department of Energy's Modern Grid Initiative report, a modern smart grid must:

• Be able to heal itself • Motivate consumers to actively participate in operations of the grid • Resist attack • Provide higher-quality power that will save money wasted from outages • Accommodate all generation and storage options • Enable electricity markets to flourish • Run more efficiently

► Market Movers:• US department of energy is spending $3.9B in “smart grid” funding aiming at

making power transmission around the country more flexible• India’s electricity demand will increase more than threefold over the next 30

years, and the country will need to invest Several Billons in the power sector to meet the demand.)

• China’s targets is to create a unified national power grid by 2020 and have a modern power market

How Freescale Beats the LCD Design Challenge

Challenge Freescale Solutions

1. Too many pins required to drive many segments

52 pins required for 192 segments in 4x48 mode



1. Too many pins required to drive many segments




2. Blinking mode takes power and resources

• Competitor parts offer blinking mode by setting a bit in a register• Power consumption increased by microcontroller

• must exit stop mode, execute the code and then go back to sleep

in every blinking period

2. Low Power Blinking mode

• Does not need to wake up the controller, can be activated and

the CPU can go to sleep, but the segments will remain blinking at the pre-set frequency

• Alternate display features can be activated to display additional data (i.e., blink temperature and time)

3. Layout is very complex because the frontplanes(FPs) and backplanes (BPs) are fixed in pin-outs

3. FrontPlane and BackPlane re-assignments

• FP and BP can be software selectable to be either FP or BP,

making board layout an easier task and very flexible for changes

4. LCD glass requires many voltages, and voltage divider resistor ladders consume too much power

• Battery voltage drops over the time to the point where displays suffers degradation by not having the optimum voltage levels

4. Internal charge pump provides all voltages required to power up LCD glass

• Internal software selectable regulated power supply that keeps constant voltage across LCD glass to avoid degradation

• LL16 offers 4 bits resolution trim to adjust contrast control

(Only for S08 and V1 cores)

• FPs and BPs are commonly distributed on all sides of the microcontroller

• Special device placement and layout must be performed to reduce electromagnetic interference (EMI) and shorten communication lines between the microcontroller and the LCD display

• Result: complex layout, and time consuming
