Loongson 1C is a cost-effective SOC chip for industrial control and the Internet of Things. The Loongson 1C includes a floating-point processing unit, supports multiple types of memory, and supports high-capacity MLC NAND Flash. Loongson 1C provides developers with a wealth of peripheral interfaces and on-chip modules, including Camera controller, USB OTG and USB HOST interfaces, AC97/I2S controller, LCD controller, SPI interface, UART interface, etc., providing sufficient computing power and multi-application connectivity.
Some highlights of this SoC are: - Single core LS232, MIPS32 instruction set compatible, main frequency 300MHZ - 16KB data cache and 16KB instruction cache - 64 bit float unit, hardware division - 8/16 bit SDRAM controller, 45 ~ 133MHz - 8/16 bit SRAM, NAND - I2S/AC97, LCD, MAC, USB, OTG, SPI, I2C, PWM, CAN, SDIO, ADC - 12 UARTs See Techinical Reference Manual for details:
