8位微控制器 -MCU FINISHED GOOD
Overview
RS08KA microcontrollers MCUs are general-purpose 8-bit devices for the ultra-low-end market. Featuring RS08 architecture, RS08KA devices are specifically crafted to be more efficient and cost effective for small memory size microcontrollers. The MC9RS08KA MCU is a general-purpose device that can be used in a wide variety of applications, including high-brightness light-emitting diodes LEDs, lighting system controls, small handheld devices, toys, AC line voltage monitoring and simple logic, analog drivers and ASIC replacements. It’s ideal for transitioning from solid-state relays and switching systems to a full electronic solution.
