The XC2300B series, with the XC2336B (LQFP-64) and XC236xB (LQFP-100) derivatives, is the low-end extension of the XC2300 microcontroller family focussing on Safety applications. With a total memory size of up to 320kB Flash and up to 34kB RAM running at up to 80MHz, the microcontrollers of this series are well suited for low-end cost-sensitive safety applicationss like Airbag, low-end Braking or Belt Pretensioner applications.
