The MB90340 Series is a member of the F2MC-16LX family and is available in the M05 and the M06 package. The MB91270 Series is a member of the FRLite family and is available in the M05 package. When looking at the M05 package of both Series, the pin-out of the power pins and the general purpose IO pins is identical. This offers the possibility of designing a target application that can be equipped with either Series. This application note compares both Series so that the application can be designed in such a way as to allow deploying either Series. The emulation chip of the MB91270 Series is the MB91V280. The emulation chip of the MB90340 Series is the MB90V340. © Fujitsu Microelectronics Europe GmbH -5- MCU-AN-300006-E-V14 Comparison of MB90340 and MB91270 Series MCU Chapter 2 Overview 2 Overview The principle differences between the two series of MCUs are highlighted in this chapter.

MB90340 Series MB91270 Series Burn-in UART UART0 UART1 Mode selection port pins P00, P01 P10, P11 3.2 Mode Setting The external bus mode is set in a two step process. First, the pins MD[2:0] determine, where the mode settings are located. Second, the mode register has to be set correctly. This is done in the start.asm file for the MB90340 Series and in the vectors.c file for the MB91270 Series.

This means that after a power-cycle, the MCU performs a reset, reads the Mode Pins and starts according to the Mode Pin settings. MCU-AN-300006-E-V14 -8- © Fujitsu Microelectronics Europe GmbH Comparison of MB90340 and MB91270 Series MCU Chapter 3 Hardware The MB91270 Series MCUs do not feature a Power-on Reset. This means that after a power-cycle, a reset must be applied externally to the INITX pin. 3.4 Pin Overview The following table compares the pin-out of the MB90340 Series to the MB91270 Series.
