The 80296SA is performance enhanced from the 8xC196NP and 8xC196NU controllers while maintaining binary code compatibility. Hence, the 80296SA can be dropped into a 8xC196NP/NU socket and immediately boost system performance. |
|
|
The 80296SA exhibits improved math performance over previous architectures making it suitable for embedded digital signal processing and feedback control systems. The 80296SA can perform 12.5 DSP MIPS and 16 general purpose MIPS. The 80296SA has 512 bytes of register RAM and 2 Kbytes of code/data |

RAM. The 80296SA utilizes the same peripherals as the 8xC196NP/NU. Additionally, like the 8xC196NU, the 80296SA includes a phase-lock loop. With the phase lock loop, an external clock drives the device at one half or one quarter the maximum internal clock frequency. Therefore, the system is designed for lower frequency external clock or oscillators while maintaining the maximum internal operating frequency. Enhancements to the chip select unit, the interrupts, and the timers were also implemented. The windowing scheme was enhanced to include the windowing of some external memory locations for direct addressing. |

The 80296SA is available in 100L QFP which is pin compatible with the 8xC196NU/NP for ease of upgradability. For existing 8xC196NU/NP users, the 80296SA provides an easy performance upgrade which translates to faster time to market. For customers who are looking for 16 bit microcontroller with an extra boost to performance, the 80296SA provides the performance edge required at an affordable price. |
