Product details

The MSP430F477IZQW: At 8 MHz, this MCU isn't breaking any speed records — it's tuned for control loops that update in the tens of microseconds, not nanosecond-level switching. The 16-bit RISC architecture with a hardware multiplier handles PID loops and LCD refresh (the peripheral set includes an LCD driver) without a problem, but don't plan on running a TCP/IP stack or heavy DSP here.

Obsolete — sourcing and lifecycle reality

The brown-out detect and watchdog timer peripherals help it survive noisy supply rails and brownout conditions common in industrial environments.

Frequently asked questions

Who supplies MSP430F477IZQW and how is it quoted for volume purchases?

We supply MSP430F477IZQW through our independent distribution network. For volume purchases, submit an RFQ — we confirm current availability and pricing at quote time. No minimum order quantity is required, but lead times depend on surplus stock levels.

What is MSP430F477IZQW's listed speed?

The MSP430F477IZQW runs at 8 MHz, which is the maximum core clock for this 16-bit MSP430 CPU16 device. That's adequate for control loops and sensor readout but not for high-speed data processing.

What is MSP430F477IZQW's series?

It belongs to the MSP430x4xx series, which features the MSP430 CPU16 core with integrated LCD drivers and analog peripherals — designed for metering and instrumentation applications.

What compliance documentation does this brand provide for MSP430F477IZQW?

Texas Instruments provides standard RoHS and REACH compliance documentation for this part. The 113-VFBGA package is lead-free compatible. No UL or IEC certification is listed in the available records.
