Cypress Semiconductor has introduced a new product family from its PSoC 4 programmable system-on-chip architecture. The new PSoC 4 M-Series expands the acclaimed PSoC 4 architecture by delivering: more programmable analog and digital blocks, 128KB flash memory, a direct memory access controller, dual control area network (CAN) interfaces and 55 general purpose I/Os with the 32-bit ARM-Cortex-M0 core—making it a natural fit to replace existing 8- and 16-bit applications. Additionally, these devices extend the design flexibility of the PSoC architecture to a wide range of sensor-based systems in home appliance, automotive and system management control applications.
“Our PSoC 4 portfolio enables customers to replace their 8- and 16-bit MCU-based products and seamlessly migrate to a 32-bit ARM platform for as low as 25-cents,” said John Weil, vice president of PSoC marketing at Cypress. “Our new PSoC 4 M-Series expands the PSoC 4 portfolio and now enables designers to create even more custom interfaces and analog front ends to add differentiation, functionality and performance to their products and create world-class, innovative solutions.”
The PSoC 4 M-Series delivers 16 programmable digital blocks including eight timer/counter/PWM blocks, four serial communication blocks and four Universal Digital Blocks—Cypress’s programmable digital blocks containing two programmable logic devices, a programmable data path and status and control registers. The programmable digital blocks can implement coprocessors to offload compute-intensive tasks from the included ARM Cortex-M0 core, which traditionally were only available in 8- and 16-bit platforms. Further, the blocks enable engineers to create emerging or custom serial communication interfaces in the available programmable hardware, such as support for Pulse-Density Modulation microphones and the USB Type-C configuration channel protocol, which typically required new silicon platforms from traditional microcontroller (MCU) vendors.
The PSoC 4 M-Series delivers 12 programmable analog blocks including four highly configurable opamps, four current-output digital-to-analog converters (IDACs), two low-power comparators, a 12-bit SAR ADC and a CapSense capacitive touch-sensing block. The programmable analog blocks enable engineers to create on-chip, custom analog front ends to support new end-product features like sensors for wearable devices without increasing product costs, size or power consumption. Cypress’s industry-leading CapSense capacitive touch-sensing technology enables engineers to add sophisticated user interfaces with advanced features like proximity sensing and water tolerance.
The scalable PSoC 4 architecture is complemented by the easy-to-use PSoC Creator Integrated Design Environment (IDE), which simplifies system design and accelerates time-to-market by enabling concurrent hardware and firmware design, and PSoC Components—free embedded ICs represented by an icon in the IDE. Together they enable rapid prototyping of end applications while minimising PCB spins and firmware changes that are typically required.
PSoC 4 M-Series is built on the low-power PSoC 4 architecture and offers five low-power modes to minimize system power consumption. It supports a low leakage retention power mode, using only 150nA while retaining SRAM, programmable logic and the ability to wake up from an interrupt. It also offers a best-in-class non-retention stop mode down to 20nA with a GPIO wakeup capability.
Cypress is demonstrating the PSoC 4 M-Series, along with its PSoC, Bluetooth Low Energy, USB Type-C, 4-PLL clock generator, automotive and memory solutions at the Embedded World 2015 exhibition in booth number 259, located in Hall 5, at the Nuremberg Messe.
PSoC 4 M-Series Development Kit
The $25 CY8CKIT-044 PSoC 4 M-Series Pioneer Kit is a highly expandable development kit that enables engineers to evaluate and create designs with a PSoC 4 M-Series device. It includes Arduino Shield, Digilent Pmod and Raspberry Pi compatible connectors, enabling customers to pick from a variety of third-party expansion boards to accelerate prototyping and time-to-market.
