Programmable system-on-chip enhances integrated systems control

20 October 2004 DSP, Micros & Memory

Cypress MicroSystems, a subsidiary of Cypress Semiconductor, has produced a new member of its programmable system-on-chip (PSoC) mixed-signal arrays. Featuring expanded digital integration functionality, these devices extend the reach of the popular PSoC architecture to address larger and more complex embedded control functions in consumer, industrial, office automation, telecom and automotive applications.

With 12 configurable analog and 16 configurable digital blocks, the CY8C29xxx family doubles the number of digital peripherals in the PSoC product line. This provides the capability to integrate more timers, counters and PWMs, says the company. For example, the new device can integrate four full-duplex UARTs and adds the ability to integrate four 14-bit ADCs in a single PSoC chip.

The new devices also include two MACs with 8-bit multipliers and 32-bit accumulators, enabling parallel maths paths with simultaneous digital filters while minimising MPU overhead. System designers also benefit from increased memory resources, with 32 Kbytes of flash for programs and 2 Kbytes of SRAM.

The new PSoC devices are available in PDIP, SSOP, SOIC, TQFP and MLF packages, up to 100 pins and 64 I/O.
