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 confidential 3 Realtek RTD2120-series Pin Configurations P5.4/PWM4 6 P5.3/PWM3 5 P5.2/PWM2 4 P5.1/PWM1 3 P5.0/PWM0 2 P1.0/T2 VCC 44 P1.1 P1.2 P1.3 NC 1 43 42 41 40 39 38 37 36 P5.5/PWM5 DSCL/P5.6 DSDA/P5.7 RST ASCL/P3.0/RXD NC ASDA/P3.1/TXD P3.2/INT0 P3.3/INT1 P3.4/T0 P3.5/T1 7 8 9 10 11 12 13 14 15 16 17 18 P7.6/CLKO2 P5.4/PWM4 48 P1.4 P1.5 P1.6 P1.7 NC NC NC VSYNC P6.7 P6.6/CLKO1 P6.5 RTD2120S 44-PIN PLCC 35 34 33 32 31 30 29 19 P7.7 P5.3/PWM3 47 20 XO P5.2/PWM2 46 21 XI P5.1/PWM1 45 P5.0/PWM0 22 VSS 44 23 NC NC 43 NC 42 24 P6.0/ADC0 VCC 41 25 P6.1/ADC1 P1.0/T2 40 26 P6 […]
