Infineon CYT2B95CACQ0AZEGS

CYT2B9 is a family of TRAVEO™ T2G microcontrollers targeted at automotive systems such as body control units. CYT2B9 has an Arm Cortex®-M4 CPU for primary processing, and an Arm® Cortex M0+ CPU for peripheral and security processing. These devices contain embedded peripherals supporting Controller Area Network with Flexible Data rate (CAN FD), Local Interconnect Network (LIN), and Clock Extension Peripheral Interface (CXPI). TRAVEO™ T2G devices are manufactured on an advanced 40-nm process. CYT2B9 incorporates Cypress' low-power flash memory, multiple high-performance analog and digital peripherals, and enables the creation of a secure computing platform.
