Abstract
Systems and methods for using memory-mapped memories in a microcontroller-based instrument are provided herein. The method includes operating the microcontroller-based instrument using a complex application or protocol and operating a highly integrated, low-power microcontroller unit (MCU). The MCU is configured to use memory mapping for accessing at least one off-MCU memory connected to the MCU by at least one interface. The MCU's memory-mapping configuration enables the off-MCU memory(ies) to behave as an extension of at least one on-MCU memory that is connected directly to the CPU to effectively extend a range of the at least one on-MCU memory, wherein the effective extended range of the at least one on-MCU memory enables the microcontroller-based instrument to utilize the complex application or protocol. The method further includes writing addresses and/or data to and/or reading addresses and/or data from the off-MCU memory using serial transmission during a memory mapped transaction.
