Nuvoton Technology NUC502
The NUC502 is an ARM7TDMI-based MCU, specifically designed to offer low-cost and high performance for various applications, like interactive toys, edutainment robots, and home appliances. It integrates the 32-bit RISC CPU with 64KB high-speed SRAM, crypto engine with OTP key, boot ROM, LDO regulator, ADC, DAC, I2C, SPI, USB2.0 FS Device, & GPIO into a cost-affordable while feature-rich micro-controller. The ARM7TDMI runs up to 81MHz on the high-speed SRAM to offer enough horsepower for many MIPS-hungry tasks, while the remaining MIPS is still able to serve the need of application program.

GENERAL DESCRIPTION
Owing to the simplicity of the NUC502 architecture that boots SpiMemory into the highspeed SRAM for program execution, the total system BOM is reduced to its minimum. Unlike usual ARM-based MCU products, the NUC502 operates without the use of SDRAM, which is usually the source of complexity, higher power consumption, and cost. For those applications, like cartridge games, that require large code storage and variation of game play scenarios, the patented Extensible XIP Addressing on SpiMemory gives the flexibility whenever program execution speed is not a critical concern. To protect the code against illegal pirating, the NUC502 provides a crypto engine that works with internal OTP2 key to encrypt the data stored at external SpiMemory when the design-in is finished. Without the knowledge of the OTP key, others can’t decrypt the data even by means of ICE debugging. The NUC502 is designed with special care to minimize the power consumption while allowing for the flexibility to reach for high performance.
