CHAPTER 1 OVERVIEW
1.1 Overview of MB90360
The MB90360 Series is a 16-bit microcontroller designed for automotive applications
and contains CAN function, capture, compare timer, A/D converter, and so on.
■ Features of MB90360 Series
MB90360 series has the following features:
●
Clock
• Built-in PLL clock multiplying circuit
• Machine clock (PLL clock) selectable from 1/2 frequency of oscillation clock or 1 to 6-multiplied
oscillation clock (4 MHz to 24 MHz when oscillation clock is 4 MHz)
• Subclock operation (8.192 kHz)
• Minimum instruction execution time: 42 ns (4-MHz oscillation clock and 6-multiplied PLL clock)
• Clock supervisor: monitors main clock or subclock independently
• Subclock mode: Clock source selectable from external oscillator or internal CR oscillator
●
16-MB CPU memory space
