CH559L 8 bit microcontroller IC

The 8 bit microcontroller CH559L with E8051 processor core is packaged in SMD format and conforms to the LFQP48 standard, aligning with the MCS51 processor standard. Its most significant feature is the ability to operate in Root-HUB mode with this controller. 79% of the instructions of this small controller are single-byte and single-cycle, and the execution speed of more than half of its instructions is 8 to 15 times faster than that of MCS51. The processing speed or operating frequency of the 8-bit CH559L microcontroller IC is 56 MHz, with a 64 KB ROM flash memory, 256-byte on-chip iRAM, and 6 KB of xRAM, some of which operates in DMA mode. Features and advantages of the small WCH CH559L processor include analog-to-digital converters, timer and PWM port, two UART ports, SPI port, and a dual-port Root-HUB for USB port functionality in both USB-Host and USB-Device modes.
