N ew Products MB91260 Series Microcontroller Mounted with the highest-speed A/D Converter in the Industry MB91260 Series A microcontroller using a 32-bit RISC CPU from the FR60Lite Series. With its high-speed product-sum macro, multi-function timer, and A/D converter at 12 inputs/3 units, this new product is optimal for devices requiring inverter control. FR60Lite Series 32-bit Overview This new microcontroller is configured with a core 32-bit RISC CPU from FR60Lite Series, making it ideal for inverter control. Besides its high-speed product-sum macro and multifunction timers configured with input capture, output compare and a waveform generation circuit, the device is mounted with A/D converters at 12 inputs/3 units. The microcontroller function is suited for a wide range of appliances, including home appliances that require inverter control (such as air conditioners and washers), as well as devices requiring system control (such as printer engines, automobile audio products, pachinko products, and so on). , Fig.1 shows FUJITSU s line-up of microcontrollers with built-in multi-function timers. 2 channels ＋2 channels) and a series of built-in, high-speed A/D converters with conversion times of 1.2μs at minimum (at machine clock operation of 33MHz, with sampling time included). The function to interlock with the multi-function timer is ideal for applications requiring inverter control. The high-speed A/D converters are capable of interlock startup with the free run timer in the multi-function timer section (output compare function) and DMAC transfer.

In interlock with the free run timer (output compare function), the device can execute delay startup from the same point, or startup at the compare clear match and zerodetection point. A/D startup point adjustment is also possible. s Multi-Function Timer Mounted This product consists of the following. 16-bit free run timer×1 16-bit output compare×6 16-bit input capture×4 8/16-bit PPG timer×8 Waveform generator×1 A/D startup compare×2 The microcontroller can generate carrier frequency, basic signals, and non-overlap signals, and is designed to perform various signal controls (waveform generator section) required for inverter control. The product can output 12 separate waveforms, and measure input pulse width/external clock cycle. ● ● ● ● ● ● s Timer Macro Repletion Besides the multi-function timer, three different types of timers are built in.
