Cypress Packs PSoC Mixed-Signal Arrays into Small-Scale MLF Package

4/30/2004 - Cypress MicroSystems Inc., a subsidiary of Cypress Semiconductor Corp. (NYSE: CY), introduced a number of the company’s popular Programmable System-on-ChipTM (PSOCTM) mixed-signal array devices in the space-saving MicroLeadFrame® (MLF) package. The small size and weight, along with excellent thermal and electrical performance, make the MLF package an ideal choice for handheld portable devices.

“PSoC gives designers the ultimate in flexibility,” said Nathan John, director of marketing for Cypress MicroSystems. “The small size and superior thermal performance of the MLF package enables designers to use PSoC devices in the most demanding portable, space-sensitive applications. They can now add analog and digital functionality to their products while further reducing their size. There’s no longer a trade-off: it’s a win/win situation.”

Utilizing flush leads, MLF packaging has a 50 percent smaller footprint and roughly half the parasitic lead inductance of conventional 4.4 mm. SSOP packages. The package offers ExposedPadTM technology as a thermal enhancement by having the die attach paddle exposed on the bottom of the package surface to provide an efficient heat path when soldered directly to the PWB. In addition to lower thermal impedance and a substantially smaller footprint, MLF packaging significantly reduces package profile height (</= 1 mm.). Thinner-profile packages are particularly useful in the design of highly integrated or portable applications that require height restrictions, thus reducing board space and OEM manufacturing costs.

Pricing and Availability
Available in 48-lead MLF packages, pricing in 10,000-unit quantities is $2.35 each for the CY8C27xxx; $1.45 each for the CY8C24xxx and $1.07 each for the CY8C22xxx.

About the PSoC Family
Programmable System-on-Chip (PSoC) devices are high-performance, field-programmable, mixed-signal arrays for high-volume embedded-control functions in consumer, industrial, office automation, telecom and automotive applications. PSoC devices integrate programmable blocks of analog and digital logic, a fast 8-bit MCU, up to 16 kbytes of flash memory and 256 bytes of SRAM and a multiply-accumulate controller (MAC).

All PSoC devices are dynamically reconfigurable, enabling designers to create new system functions on-the-fly. Re-using the same silicon for different functions on different clock cycles, designers can achieve more than 120% utilization of the die in many cases. In the automotive PSoC LIN bus reference design, the same transistors are re-used four times to support the different LIN communication modes; in doing so, these transistors consume less than 10 percent of PSoC hardware resources and less than 10 percent of the PSoC MCU cycles.

To further shorten design cycles, the PSoC family includes pre-programmed, specialized versions for lighting, energy, motor control, communications, automotive and battery applications. Each family member comes with a reference design and extensive application notes to speed application development.
