Abstract

Read online

An embedded NOR Flash controller is descripted for quickly IAP(in application programming),no need of interrupt vector remap by software, but direct address remap by hardware reboot from middle location with dual Flash banks. The Flash controller can support read operation in the process of IAP, and get right read results. The Flash controller has a 1 ?滋s configuration register which can be used to calculate expected timing values for programming or erase automatically, reducing the software workload to configure more timing values one by one with different working frequency. It is verified after simulation and FPGA prototype verification,and taped out on UMC55 nm process in MCU. The samples of MCU with IAP working well prove further the Flash controller.
