With CAN FD communication

Infineon Technologies announced the PSoC 4100S Max family. It features CAN FD as well as Flash memory and general-purpose inputs/outputs (GPIO) for human-machine interface (HMI) applications to support the Capsense touch sensors.

The PSoC 4100S Max expands the scalable PSoC 4 portfolio. PSoC 4 is a scalable and reconfigurable platform architecture for a family of programmable embedded system MCUs (micro-controller unit) with an Arm Cortex-M0+ central processing unit. It combines programmable and reconfigurable analog and digital blocks. It is a member of the PSoC 4 platform architecture. It is a combination of a micro-controller with regular communication and timing peripherals, a capacitive sensing system, programmable general-purpose continuous-time analog blocks, and programmable connectivity. The products are compatible with members of the PSoC 4 platform for new applications and design needs.

Available in 7 mm² x 7 mm², 10 mm² x 10 mm², and 14 mm² x 14 mm² packages, the introduced PSoC 4100S Max is suitable for industrial control, automotive HMI, home automation and home appliances including robotics, inductive sensors, washing machines, refrigerators, air conditioners, smart thermostats, and printers.

The product includes up to 384K Flash memory and up to 84 GPIOs, serial communication via CAN FD, high-speed, long-range wired communication, and I²S “commander” for embedded audio solutions. The CAN FD block used in the PSoC is certified to be Bosch CAN standard compliant and operates at 5 Mbit/s, explained the company. It incorporates a 4-KiB receive and transmit buffer. The added features also include dual fifth-generation Capsense blocks, which deliver differentiated HMI and touch sensing solutions. The PSoC devices also include a cryptographic accelerator for cryptographic functions for a more secure interface for tomorrow’s touch user interface applications, said the company.

“Infineon is a leading provider of capacitive touch solutions. The PSoC 4100S Max with next-generation Capsense is the best yet with both mutual and self-capacitance sensing for various touchscreen features,” said Steven Tateosian, Vice President, Internet of Things, Compute, and Wireless Business Unit of Infineon. “This next-generation product provides the industry’s best touch sensing with scalability, while reducing the overall bill of materials for designers’ boards. Additionally, this family delivers industry-leading signal-to-noise ratio under some of the most severe touch sensing environments.”

Compatible with the company’s latest Modustoolbox 3.0 development platform, the devices allow use cases including consumer IoT, automotive HMI, industrial, smart home, wearable, and other applications. In addition to PSoC 4, the Modustoolbox 3.0 is also compatible for embedded applications using Infineon products including PSoC 6, XMC, Airoc Wi-Fi, Airoc Bluetooth, and EZ-PD PMG1 micro-controllers. PsoC 4 can be ordered now. Start of production for the AEC Q-100 automotive-qualified version is planned for quarter two of 2023.
