Cypress Semiconductor Corp. introduced a new 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 coprocessors that offload sensor processing from the host and reduce overall system power consumption. The new SoC Analog Coprocessor integrates programmable analog blocks, including a new 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 PSoC Analog Coprocessor 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. Cypress will demonstrate the PSoC Analog Coprocessor, along with its SoC, FM Flexible MCU, Bluetooth® Low Energy and Energy Harvesting Power Management IC solutions at Sensors Expo from June 21 to 23 in booth 416 at the McEnery Convention Center in San Jose.

The design of custom sensor interfaces is enabled by Cypress’s free SoC 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 Coprocessor by dragging and dropping components on the PSoC Creator schematic and customizing them with graphical component configuration tools. The components offer fully engineered embedded initialization, calibration and temperature correction algorithms.

“The PSoC Analog Coprocessor makes sensor interface design accessible to embedded systems engineers without requiring expertise in analog system design; this comes with the added benefit of enabling rapid prototyping and design iterations in software with no hardware changes by simply modifying components in PSoC Creator,” said John Weil, vice president of MCU marketing at Cypress. “Cypress has pioneered and perfected programmable analog technology for 15 years, and now our PSoC Analog Coprocessor provides the most programmable analog IP per square millimeter in a tiny chip-scale package.”

The SoC Analog Coprocessor is available in a 3.7-mm 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 opamps, programmable gain amplifiers, analog multiplexers, analog-to-digital converters, analog filters and digital-to-analog converters.
