Description

The MB90F244 is a 16-bit microcontroller optimized for applications in mechatronics such as HDD units. The architecture of the MB90F244 is based on the MB90242A, and embedded with a 128-Kbyte flash memory.

The instruction set is based on the AT architecture of the F2MC* family, with additional high-level language supporting instruction, expanded addressing modes, enhanced multiplication and division instructions, and improved bit processing instructions. In addition, long-word data can now be processed due to the inclusion of a 32-bit accumulator.

The MB90F244 includes a variety of peripherals on chip, such as the device is equipped with 8-channel 8/10-bit A/D converter, UART, 3-channel 16-bit reload timers, 1-channel 16-bit timer, 4-channel 16-bit input capture and 4-channel DTP/external interrupts.

Differences between the MB90F244 and MB90F243 to meet the 3.3 V ±0.3 V power supply voltage are that the power consumption of the MB90F244 is about 10% less than that of the MB90F243 and the operating frequency of the MB90F244 is up to 50 MHz from 32 MHz of the MB90F243.

* : F2MC stands for FUJITSU Flexible Microcontroller.
