C166CBC (C161U, SDA6000) Microcontrollers - Architectural Overview of the enhanced 16-Bit Microcontroller

The C161U is a low-cost, high-performance, general-purpose 16-Bit microcontroller that includes USB device interface at full speed of 12 Mbits. The device combines the successful Infineon C166 16-Bit static core technology and offers many on-chip peripheral functions such as USART, 5 timers, Watchdog timer, 8 DMA channels, 8 software configurable bi-directional USB end-points, and a high number of programmable I/Os. C161U’s high performance, low cost, and rich peripheral functions provide users the maximum flexibility and performance to implement additional value-added software for product differentiation.

The C165H device combines the successful Infineon C166 16-bit full static core with four independent HDLC controllers, IOM-2 interface and 3kbyte of on-chip Dual-Port RAM. The C165H addresses all embedded HDLC features in ISDN-TA, Intelligent-NT and low cost SOHO-PBX designs offering up to 18 MIPS along with legacy peripherals, such as USART, SSC/SCI and Timers. The C165H device core has a built-in DMA, which provides maximum flexibility and performance. Off-loading the CPU in such a manner allows the user to implement value add software features enabling product differentiation.

The SDA 6000/6001 integrates a high-speed 16-bit C166 microcontroller with digital signal processing for VBI data acquisition and the most flexible display controller ever seen since Megatext. The SDA 6000/6001 is the cost-effective solution for consumer products that require flexible pixel graphics for the optimum user interface:

Television sets with Teletext up to Level 2.5, Electronic Program Guides (NexTView and others), HTML-, GIF-, and JPEG-based applications
Telecommunication devices with gray-scale or color pixel displays
Display-oriented consumer info-devices
