MSP430FG478IZCAR

Microcontrollers Overview

The MSP430FG478IZCAR is a 16-bit ultra-low-power mixed-signal microcontroller from the Texas Instruments MSP430x4xx family. It features 48KB of flash memory and 2KB of RAM, housed in a 113-ball nFBGA (ZCA) package. The device operates within a supply voltage range of 1.8V to 3.6V and supports processor frequencies up to 8MHz at 2.5V. Key peripherals include a 16-bit sigma-delta ADC, dual 12-bit DACs, two configurable operational amplifiers, Timer_A with three capture/compare registers, Timer_B with seven capture/compare-with-shadow registers, and an LCD driver supporting up to 128 segments.

• Configurable analog front-end with dual operational amplifiers and on-chip comparator
• Comprehensive connectivity via dual Universal Serial Communication Interfaces (USCIs)

Microcontrollers Applications

• Analog and digital sensor systems
• Digital motor control
• Hand-held meters

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'IZCAR' against the latest TI Package Option Addendum to confirm availability status and exact pinout configuration. Ensure compatibility with existing PCB footprints for the 113-ball nFBGA package. Cross-reference the device revision history for any updates to electrical specifications or recommended operating conditions prior to final design implementation.

Microcontrollers Selection Notes

Select this component when designing portable measurement applications requiring extended battery life combined with precise analog signal processing. The inclusion of dual op-amps and a 16-bit ADC makes it suitable for low-frequency sensor interfaces. Consider the 113-ball nFBGA package constraints regarding thermal dissipation and board space compared to QFP alternatives if higher I/O density is required.

Microcontrollers Part Context

This device belongs to the MSP430FG47x series, which shares a common peripheral set but varies in flash memory size. The FG478 provides 48KB of flash, positioned between the 32KB FG477 and the 60KB FG479. All variants in this family utilize the same 16-bit RISC CPU core and offer identical peripheral configurations, ensuring software compatibility across the series while differing only in program storage capacity.

Microcontrollers Replacement Considerations

The MSP430FG478IPNR is a documented alternative within the same family, offering identical functionality in an 80-pin LQFP package. Designers must account for the significant difference in physical footprint and pin assignments when transitioning from the BGA package to the QFP package.
