Ultra Low Power and Gate Count ARM Cortex-M0 Processor Upgrades 8-Bit
Solution
ARM (LSE:ARM) (Nasdaq:ARMH) and Melfas, a leader in capacitive-sensing
touch input solutions, today announced that Melfas has chosen the ARM®
Cortex™-M0 processor and ARM physical IP libraries for their future
controller ICs for capacitive touch screen solutions.
“The ultra low power and gate count of the Cortex-M0 processor, combined
with its 32-bit performance efficiency, makes it an ideal choice for
mobile touch screen applications supporting increasing panel sizes,”
said B.W. Lee, CEO, Melfas. “This upgrade from our previous 8051-based
solution will enable us to deliver a competitive advantage in the energy
efficiency, precision and cost effectiveness of our products.”
Melfas has many years’ expertise in designing turnkey touch screen
module solutions including controller IC, circuitry, driver software,
and patterned ITO panel with window lens and test system. It has shipped
over 40 million controller ICs since 2006. According to market research
firm, DisplaySearch, the total touch screen module market will grow from
$3.6 billion in 2008 to $9 billion by 2015, with a CAGR of 14 per cent.
“Our engineers were already familiar with the Keil software development
tools, which support both 8051 and ARM Cortex-M0 processor-based
devices,” said D.J. Min, VP Engineering, Melfas. “We were able to
quickly and easily evaluate the new processor using our existing 8051
code base. The results demonstrated that we could halve the flash memory
requirement using the Cortex-M0 processor, and reduce the MHz
requirement by 5x, saving power.”
“The use of touch screen controllers in products ranging from mobile
phones, personal media players, digital cameras, navigation devices, to
home appliances is rapidly increasing. The Cortex-M0 processor’s energy
efficiency and small size make it particularly suited for these
applications,” said Eric Schorn, VP marketing, Processor Division, ARM.
“The agreement with Melfas is a further endorsement of the Cortex-M
family of low power processors and ARM physical IP, and demonstrates
ARM’s low power leadership.”
The Cortex-M0 processor is the lowest power and smallest 32-bit ARM
processor. It offers an optimal blend of ultra low-power, energy
efficiency and low gate count, with binary upwards compatibility with
the higher performance ARM Cortex-M3.
