Product details

8 MHz clock — timing budget for metering loops

The 8 MHz CPU speed is typical for the MSP430x4xx value line — adequate for periodic ADC reads, LCD segment updates, and serial communication at moderate baud rates.

48 KB Flash — firmware capacity and field updates

48 KB of Flash (48K x 8 plus 256 bytes) is enough for a standalone metering or sensor node firmware image with calibration tables and a bootloader for field updates. The 256-byte extra row is typically used for calibration constants or unique device identifiers. The Flash is field-reprogrammable, so firmware can be patched in-system via UART or SPI.

Package — 113-VFBGA Microstar Junior

The 113-ball VFBGA measures 7x7 mm. The BGA footprint requires solder-paste stencil design and X-ray inspection for void detection.

Frequently asked questions

Is the MSP430F478IZQW obsolete?

Yes, Texas Instruments has marked the MSP430F478IZQW as Obsolete. The last-time-buy window has closed. The part is available only through surplus or broker channels, sourced to order against an RFQ.

What replaces the MSP430F478IZQW?

No official successor is listed in the Texas Instruments documentation for this order code. The MSP430F47x3 family shares a similar peripheral set but is not a pin-compatible drop-in; verify BGA ball-map compatibility before substituting. For a validated replacement, review the active MSP430F5xx or MSP430F6xx families with comparable analog integration.

Where can I buy the MSP430F478IZQW?

The MSP430F478IZQW is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. Submit an RFQ for a firm price and lead-time estimate.

What is the MSP430F478IZQW's core speed?

The MSP430 CPU16 core runs at 8 MHz, which is the maximum CPU clock frequency for this device.

What is the MSP430F478IZQW's program memory size?

It has 48 KB of Flash program memory (48K x 8 plus 256 bytes for calibration/ID storage).
