CS8955 8051 Embedded Micro-Controller with 64K Flash ROM and ISP Production
 General Description:
The CS8955 micro-controller is an 8051 CPU core embedded device targeted for LCD Monitor, LCD TV, Home Appliance, or Consumer Products application. The CS8955 is pin-out compatible with MCS-51 family
MCU. It includes an 8051 CPU core, a 64K-byte internal program Flash-ROM, a 512-byte SRAM, 6 channels of PWM DAC, and 4 channels of 6-bit ADC (Analog to Digital Converter). It also includes a Boot-Code-Free ISP (In System Programming), which allows users to update the programming codes easily. In addition, there are two IIC Slave B ports supporting VESA DDC 2B/2Bi/2B+/CI standards for both D-sub and DVI interfaces in LCD Monitor/TV application. An external 64K bytes data flash memory can be accessed by properly setting of Port 0, Port 2 and Port 3.6/3.7.
