1.1 Feature of MB90335 Series
The MB90335 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. 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 MB90335 Series
In the MB90335 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 to 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 M bytes
●
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
●
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
