Cypress Semiconductor introduced a PSoC programmable system-on-chip that simplifies the design of next-generation industrial, home appliance and consumer systems that require multiple sensors.
Many Internet of Things (IoT) applications require multiple sensors and can benefit from dedicated co-processors that offload sensor processing from the host and reduce overall system power consumption. The PSoC analog co-processor integrates programmable analog blocks, including a universal analog block (UAB) which can be configured with GUI-based software components. This combination simplifies the design of custom analog front ends for sensor interfaces by allowing engineers to update sensor features quickly with no hardware or host processor software changes, while also reducing BOM costs.
For example, in home automation applications, engineers can easily configure the device to continuously monitor multiple sensors, such as temperature, humidity, ambient light, motion and sound, allowing the host to stay in a standby low-power mode. Future design changes to support new sensor types can also be easily implemented by reconfiguring the programmable analog blocks.
The design of custom sensor interfaces is enabled by Cypress’s free PSoC Creator integrated design environment (IDE), which simplifies system design by enabling concurrent hardware and firmware development using PSoC Components – free embedded ICs represented by an icon in the IDE. Engineers can easily configure the programmable analog blocks in the PSoC analog co-processor by dragging and dropping components on the PSoC Creator schematic and customising them with graphical component configuration tools. The components offer fully engineered embedded initialisation, calibration and temperature correction algorithms.
The PSoC analog co-processor is available in a 3,7 by 2,0 mm chip-scale package option. Based on a 32-bit ARM Cortex-M0+ signal processing engine, it delivers a low-cost, fully programmable analog front end with op-amps, programmable gain amplifiers, analog multiplexers, analog-to-digital converters,
