Cypress Semiconductor has introduced a fully-qualified PSoC 5LP programmable system-on-chip family. The new devices provide high-performance programmable analogue, the best ADCs, according to the company, 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’s IDE.
Other features include 0.5V startup with integrated Boost, 1.71-5.5V fully functional analogue, and a wide operating range of 0.5-5.5V. These various capabilities open up new applications that require single-cell battery performance and high-precision analogue but not fixed function MCUs.
The PSoC 5LP offers programmable analogue precision with differential 12-bit SARs and a 20-bit DelSig ADC supported by a class leading 1.024V 0.1% accurate internal voltage reference. The best-in-class ADCs includes 62 channels, fully functional analogue 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 analogue 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 the Components are configurable to meet individual application requirements to deliver a single chip solution.
Consuming only 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. As a result they are suitable for single cell battery operation, Cypress’s boost technology allows designers to power up and regulate on as little as 0.5V. However, unlike fixed-function MCUs, PSoC allows designers to further reduce power consumption by customising each peripheral Component so unnecessary functions do not consume any power.
PSoC 5LP offers programmable analogue 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 customise logic functions, peripherals, the analogue front end and analogue subsystems, designers can achieve greater system integration and a reduced system bill of materials. PSoC enables designers to solve complex problems easily with more than 80 pre-verified, production-ready Components.
PSoC Creator allows users to configure PSoC programmable hardware into a personalized, one-chip solution. The free IDE comes with production ready Components and APIs for easy and fast configuration of the device, and enables users to create and replicate their own custom Components.
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties and they integrate configurable analogue and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings.
