Details
Overview This chip is the micro-processor of LCD monitor. It uses the Designware DW8051 of Synopsys as the 8051 core of this chip and is compatible with other industry 8051 series. Also, 96Kbyte FLASH with 8 bit bus is embedded in this chip which is licensed from TSMC 0.18um e-FLASH process. Here we use the package of PLCC44/LQFP48/QFP44 if we would like to have a discrete MCU controller or we make a multi-chip package with our LCD monitor controller to form one chip package to save the cost of package and PCB material.Features • Operating voltage range : 3.0V to 3.6V • 8051 core, CPU operating frequency up to 50MHz • 4 clocks per machine cycle • 256-byte internal RAM • 512-byte external data RAM, including 256-byte DDC RAM(128-byte x 2) and 256-byte general purpose RAM • 96K-byte flash memory, 64k for program and 32k for saving parameter • Two DDC ports compliant with VESA DDC1/2B/2Bi/CI • Three channels of PWM DAC with programmable frequency from 100K to 100Hz • Watchdog timer with programmable interval • Three 16-bit counters/timers (T0, T1, and T2) • One PLL to provide programmable operating frequency and clock output, 2 clock output ports • One full-duplex serial port • Six interrupt sources with 2 external interrupts • Four channels of 6-bit ADC • Hardware In System Programming(ISP) capability, no boot code required • Built-in Low voltage reset circuit • Embedded 1.8V regulator • Code protection • Available in 44-pin PLCC, 44-pin QFP or 48-pin LQFP package
