Automotive PSoC™ 4200 - Infineon Technologies

Overview

The automotive PSoC™ 4200 product family, based on this platform, is a combination of a microcontroller with digital programmable logic, high-performance analog-to-digital conversion, opamp with Comparator mode, and standard communication and timing peripherals.

The PSoC™ 4200 products will be fully upward compatible with members of the PSoC™ 4 platform for new applications and design needs. The programmable analog and digital subsystems allow flexibility and in-field tuning of the design.

Universal Digital Blocks

Universal digital blocks are programmable digital blocks that can be configured for custom state machines, custom logic functions, or custom digital interfaces. UDBs can be cascaded together to create wider than 8-bit functions.

UDBs can be configured via a variety of design methods in the PSoC™ Creator IDE tool suite. These methods include using digital logic components in schematic capture, using the graphical state machine editor, or using Verilog code in the code editor.

PSoC™ Enables:

High-performance USB audio streaming using DMA and precision clocks, allowing up to 24-bit 96-kHz stereo
Up to eight I2S audio channels using Universal Digital Blocks (UDBs)
Capacitive touch interface
Battery management with programmable analog front end
LEDs with TCPWM
