New PSoC 5LP family powers high-precision programmable analog with a single-cell battery to advance embedded design

December 13, 2012 // By Paul Buckley
Cypress Semiconductor Corp. has introduced the fully-qualified PSoC 5LP programmable system-on-chip family.

The new devices claims to provide unmatched high-performance programmable analog, the best ADCs available on an ARM Cortex-M3-based device, and the flexibility to design custom systems with 80+ pre-verified production-ready Components for the PSoC Creator IDE.

Other class-leading features include 0.5 V startup with integrated Boost, 1.71-5.5 V fully functional analog, and the industry’s widest operating range of 0.5-5.5 V. These capabilities open up new applications needing single-cell battery performance and high-precision analog to a world beyond fixed function MCUs. PSoC 5LP devices are shipping today.  

PSoC 5LP offers programmable analog precision with differential 12-bit SARs and a 20-bit DelSig ADC supported by a class leading 1.024 V 0.1% accurate internal voltage reference. The best-in-class ADCs includes 62 channels, fully functional analog from 1.71 - 5.5V and the widest input signal range from 0 - 5.5V of any ARM Cortex-M device. The wide variety of PSoC Creator programmable analog Components include OpAmps, Comparators, Trans Impedance Amplifiers (TIAs), Programmable Gain Amplifiers (PGAs), Mixers, Segment LCDs, CapSense touch sensing, DACs, Analog Muxes and more. All of Components are configurable to meet individual application requirements to deliver a single chip solution.

PSoC 5LP was designed to deliver more than just standard low power consumption. Consuming 300 nA in Hibernate mode, the new devices can wake-up on IOs and retain the state of the CPU core, SRAM and device configuration. Ideal for single cell battery operation, Cypress’ boost technology allows designers to power up and regulate on as little as 0.5 V. Unlike fixed-function MCUs, PSoC allows designers to further reduce power consumption by customizing each peripheral Component so unnecessary functions do not consume any power.

PSoC 5LP offers programmable analog and digital with flexible routing and interconnect in easy-to-use Components within PSoC Creator. Designers can easily build their own custom embedded controller, implementing standard and proprietary protocols with immunity to specification changes. With the ability to customize logic functions, peripherals, the analog
