The 8XC196NT 16-bit microcontroller is a high performance member of the MCSé 96 microcontroller family. The 8XC196NT is an enhanced 8XC196KR device with 1 Mbyte of linear address space, 1000 bytes of register RAM, 512 bytes of internal RAM, 20 MHz operation and an optional 32 Kbytes of OTPROM. Intel’s CHMOS III-E process provides a high performance processor along with low power consumption.

Ten high-speed capture/compare modules are provided. As capture modules event times with 200 ns resolution can be recorded and generate interrupts. As compare modules events such as toggling of a port pin, starting an A/D conversion, pulse width modulation, and software timers can be generated. Events can be based on the timer or up/down counter.
