The RA4M2 32-bit microcontroller (MCU) family uses the high-performance Arm® Cortex®-M33 core with TrustZone support. Cooperating with the on-chip Secure Crypto Engine (SCE), it can realize the function of a security chip. Built on a highly efficient 40nm process, the RA4M2 is powered by an open and flexible ecosystem concept called the Flexible Software Package (FSP), which is built on FREERTOS and can be extended to use other real-time operating systems (RTOS) and middleware

Selectable time-out watchdog timer, low VCC detection and reset assertion, five standard reset threshold voltages, reprogrammed low VCC reset threshold voltages, using a special programming sequence. Reset signal valid to VCC = 1V, long battery life, low power consumption

The HIP4081A is a high frequency, medium voltage full-bridge N-channel FET driver IC in 20-pin plastic SOIC and DIP packages. The HIP4081A can drive all possible switch combinations except those that would result in a shoot-through condition.
