1. Automotive PSoC™ 4 Features

Infineon has a lineup of high-performance, low-power 32-bit Automotive PSoC™ 4 (Programmable System on Chip) as automotive microcontrollers. In addition to general MCU peripheral peripherals, it incorporates an analog block that can program the connection of each component such as the industry's No. 1 capacitive sensor, operational amplifier, ADC, etc., and a digital block that can efficiently program custom logic. increase.

Industry's No. 1 capacitive sensor (CAPSENSE™)

Infineon's capacitive sensor (CAPSENSE™) installed in Automotive PSoC™ 4 has shipped more than 1 billion units since its introduction in 2003, and has the industry's No. 1 track record. Over 15 years of continuous development, CAPSENSE™ ensures high reliability.

・Best-in-class high SNR in the industry
・High water resistance
・High noise immunity that meets automotive EMI/EMC requirements
・Low power consumption
・In addition to self-capacitance and mutual-capacitance sensors, new inductive sensors are supported.
・The latest high-sensitivity electrostatic sensor: Noise error is eliminated by a new differential method

Custom analog front end with programmable analog block

Automotive PSoC™ 4 offers op amps that can be connected directly to the ADC inside the device. This makes it possible to configure an analog front end without using external components, such as configuring a buffer or gain amplifier, or creating a differential amplifier circuit using two operational amplifiers.

Example of sensor system integration with flexible AFE design

Specification scalability and BOM cost reduction with programmable digital blocks

Automotive PSoC™ 4 is equipped with timers, PWM, SCB, segmented LCD drivers, smart I/O, and built-in LUTs for Boolean operations and simple logic operations. In addition, as a UDB (Universal Digital Block), 16 16-bit flip-flops such as PLD are configured in two stages, including digital elements that can perform logic operations before and after, and can perform logic operations using memory elements. Is possible.

In addition, it is also possible to select the desired functions of the designer, build them on software, and use them as a digital/analog mixed custom MCU.
