Comparison of MB90340 and MB91270 Series MCU
Chapter 1 Introduction
1 Introduction
This application note compares the MB90340 Series MCUs and the MB91270 Series MCUs.
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.

design.

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.

Note: The device MB91F272 supports only the Single Chip and the Internal ROM modes.
The mode register MODR of the MB91270 Series, located at address 0xFFFF8, has to be
set in the vectors.c file as shown in the following table.

Note: The device MB91F272 supports only the Single Chip and the Internal ROM modes.
3.3
Power-on Reset
The MB90340 Series MCUs feature a Power-on Reset. This means that after a power-cycle,
the MCU performs a reset, reads the Mode Pins and starts according to the Mode Pin
settings.

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.

LIN-USART
For the LIN function of the LIN-USART, the LIN break detection is connected to a fixed ICU.
The following table shows the assignments. Differences between the MB90340 Series and
the MB91270 Series are highlighted.

Chapter 5 External Bus
5 External Bus
This chapter describes the differences between the MB90340 Series and the MB91270
Series with respect to the usage of the external bus.
5.1
Chip Select
The chip select signals CSX[3:0] are assigned to the pins P9[3:0] respectively. If these pins
are used as general purpose IO by your application, make sure to disable the chip select
feature.
The chip select feature is disabled by setting the Chip Select Enable Register CSER=0x00.

Bus Operation Frequency
The external bus of the MB91270 Series devices is specified for an operation frequency of
up to 16 MHz. Before selecting a PLL setting that results in an internal base clock that
exceeds 16 MHz, make sure that the external bus frequency is set to a lower frequency.
The clock divider for the external clock is set by Base Clock Division Setting Register 1
(DIVR1) according to the following table. The register bits T[3:0] are located at bits
DIVR1[7:4] respectively.

Hold Function
The MB90340 Series supports a Hold Function. In the MB91270 Series, only the evaluation
chip MB91V280 supports it at this time. The signal names differ. Please see the table below
for the corresponding signal names.
