Feature Of Mb90330 Series - Fujitsu F2MC-16LX Hardware Manual

CHAPTER 1 OVERVIEW
1.1

Feature of MB90330 Series

The MB90330 series are 16-bit microcontrollers designed for applications, such as
personal computer peripheral devices, that require USB communications. The USB
function enables not only 12-Mbps function operations but also simplified host
operations (Mini-HOST). It is equipped with functions that are suitable for personal
computer peripheral devices such as displays and audio devices, and control of mobile
devices that support USB communications.
Feature of MB90330 Series
In the MB90330 series, there are the following features.
Built-in PLL clock multiplying circuit
• When the original oscillation is 6 MHz. Operating clock (PLL clock) of 3-24 MHz can be selected from:
divided-by-two of the original oscillation or 1-, 2-, or 4-times multiplication of the original oscillation.
A clock for USB is 48 MHz.
• Minimum instruction execution time of 41.6 ns (at oscillation of 6 MHz, four multiplied PLL clock,
operation at Vcc of 3.3 V)
Maximum memory space: 16 Mbytes
Instruction system optimized to control usage
• Data type which can be handled: Bit/byte/word/longword
• Standard addressing mode: 23 types
• High-precision operation enhanced by the employed 32-bit accumulator
• Signed multiplication and division, and enhanced RETI instructions
Instruction system that supports high-level language (C language) multitasking
• Adoption of system stack point
• Instruction set symmetry and barrel shift instructions
For no multi-bus/multi-bus
Higher execution speed: 4-byte queue
Powerful interrupt function (priority is programmable and can be set to eight levels): 8 external
interrupts
Data transfer function
• µDMAC: maximum 16 channels
• Extended intelligent I/O service function: maximum 16 channels
