Cypress Offers Web Seminar on Designing PSoC Switch Capacitor Filters

7/12/2004 - Cypress MicroSystems Inc., a subsidiary of Cypress Semiconductor Corp. (NYSE: CY), announced that it will host a one-hour web seminar on the process of designing a switch capacitor filter using the company’s popular PSoCTM configurable mixed signal array device, which is capable of implementing up to four Universal Filter Blocks. The seminar, entitled “Designing PSoC Switch Capacitor Filters” will be broadcast live on July 13 at 9:00 a.m. Pacific Time.

Filters are essential to the operation of electronic circuits, however many microcontroller programmers find it to be a difficult and complex subject. Cypress MicroSystems technology expert Dave Van Ess will address fundamental filter basics and guide participants through the process of a designing a filter to meet their specific requirements.

About the PSoC Family
A true system-on-a-chip, PSoC devices are configurable mixed signal arrays that integrate the microchip and related peripheral circuits typically found in an embedded design. Utilizing easy-to-use development tools, designers select configurable, pre-characterized library elements to provide analog functions such as amplifiers, ADS, DACs, filters and comparators and digital functions such as timers, counters, PWMs, SPI and UARTs. PSoC analog performance includes rail-to-rail inputs, programmable gain, 14-bit ADCs, and analog modulator.

In addition to these configurable analog and digital blocks, PSoC devices include a fast 8-bit microcontroller, up to 32KB of Flash memory, 2KBof SRAM, an 8x8 multiplier with 32-bit accumulator, power and sleep monitoring circuits, a precision real time clock and hardware I2C communications.

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 percent 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.
