Min-Do Kwon, Seok-Ho Seo, Il-Ki Kim · 2002
The EFMCU (Embedded Flash MCU) for digital multimedia applications is designed and fabricated with a ARM7TDMI/sup TM/ CPU core, 192 K bytes flash memory, 4 K bytes SRAM, 10-bit ADC and various functional peripherals. These modules are connected to AMBA (Advanced Microcontroller Bus Architecture) bus. The EFMCU is operated with a clock frequency of 66 MHz at 3.3 V single power, and can support both on-chip and on-board programming of the embedded flash. The technology of EFMCU is the 0.35 /spl mu/m triple-well 2-poly 3-Metal CMOS process. The chip size is 36.8 mm/sup 2/, and the package type is 100 TQFP.
