Overview
CH559 is a MCS51 compatible E8051 core microcontroller, 79% instructions of CH559 is single byte or single cycle, and average instruction speed is 8 to 15 times faster than the standard MCS51. CH559 support up to 56MHz system clock, built-in 64KB Flash-ROM, 256B on-chip iRAM, 6KB on-chip xRAM, and some of xRAM support DMA mode. CH559 built-in ADC converter, 4timers/PWM, 2UART, 2*SPI, and dual port Root-HUB, which support USB-Host and USB-Device Mode.
