Flash MCUs cut the cost of high-end
control
Two new high-speed Flash microcontrollers suit motor control, induction heating and other industrial and consumer applications that require 100DMIPS performance and excellent real-time behaviour.
Renesas Technology Europe has announced two new high-speed Flash microcontrollers for motor control, induction heating and other industrial and consumer applications that require 100DMIPS performance and excellent real-time behaviour The SH7146F and SH7149F also have a large timer resource and triple ADC that allows two motors to be driven from a single device

The H8/38004F MCU offers extremely low power consumption together with 32Kbyte single-supply on-chip Flash memory and is the first in the SLP series that is available in a 64-pin quad flatpack.
This results in a major cost reduction compared with systems with one microcontroller per motor.
Joachim Hupper, Marketing Specialist in the Consumer/Industrial Division of Renesas Technology Europe, explains: "With 256Kbyte of zero-wait Flash memory these devices target the heartland of high end embedded microcontrollers, but offer new levels of performance and real-time response speed at cost levels lower than ever before".
"The microcontrollers also feature triple ADC to support advanced motor control performance, even at high motor speed, when two ADC are not enough".

Microcontroller takes third serial line onboard
The latest microcontroller from Renesas Technology Europe incorporates three high-performance serial channels.
The SH7146F and SH7149F are built using Renesas Technology's MONOS (metal oxide nitride oxide silicon) Flash technology, the industry's fastest embedded Flash technology with read access times of just 12.5ns.
The central nitride enables small cell sizes, resulting in high read access performance at low cost levels.
Both devices have two advanced timer units called the MTU2 and the MTUS2S.
The MTU2 has six channels of 16bit timers that can be used for general-purpose timer tasks and for driving an electrical three-phase motor simultaneously.
For this, the timer generates the required six-phase PWM, has an emergency hardware shutdown input and understands quadrature encoder feedback.
The MTU2S is a subset of the MTU2, namely the part of it that has the motor control capability.
Hence, all SH microcontrollers with both the MTU2 and the MTU2S can drive two electrical motors.
The SH7146F and SH7149F each have 256Kbyte of MONOS Flash, which supports 5V/80MHz zero-wait operation.
The devices also have 8Kbyte RAM and a peripheral set comprising a data transfer controller (DTC) for flexible and autonomous data movements, three serial ports, a watchdog, an additional compare-match timer and up to 63 IO lines.
The SH7146F is available now in an 80-pin QFP and the SH7149F is available in a 100-pin QFP with an 8bit external bus option to connect external peripherals.
Both packages are RoHS compliant.
The devices are supported by Renesas' popular E10A-USB on-chip debugger and an evaluation board.
