CD9002A-56IBG USB 2.0 peripheral controller with 16K RAM, 40 GPIOs, and serial debugging-ChisynV Microelectronics (Beijing) Co., Ltd.

CD9002A series is a USB microcontroller based on the enhanced 8051 core in line with the industrial standard. It supports two modes of USB2.0 protocol, high-speed 480mbps and full-speed 12mbps. The enhanced 8051 can work at 48, 24 and 12Mhz frequencies; Each instruction cycle is 4 clocks, which is 3 times the speed of the standard 8051. CD9002A series has built-in up to 16K bytes of on-chip SRAM space, which can be used to store user code or data. CD9002A series provides UART, I2C, GPIO and other common low-speed communication interfaces other than USB interface for communication with other peripherals. CD9002A series supports powerful data transmission functions such as SlaveFIFO and PIF (programmable interface), Based on the CD9002A series firmware framework provided by Corebai, it can achieve data transmission capacity of more than 50MB / s, and the maximum bandwidth is USB2.0.
