WT6573UF数据手册Weltrend中文资料规格书

描述 Description

The WT6573UF is a USB full speed / low speed device controller with Turbo 8052 CPU, 16K-byte Flash ROM, 512-byte SRAM, 19-channel 12-bit ADC, 3-channel 8-bit PWM, standard RS232 interface, SPI master interface, I2C master/slave interface. In-System-Programming (ISP) function by USB or I2C interface, and on-chip ICE. WT6573UF is suitable for the USB peripheral applications, such as PS3 game pad/joystick, USB game controller, USB MIDI keyboard, USB touch-pad, or any USB devices with ADC applications. When USB-related circuit and V33 regulator are disabled, WT6573UF could be used for portable applications which are powered by battery (VBAT <= 3.6V).
