Product details
Overview
MSP430FG4619IZQWT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 120KB+256B flash, 4KB RAM, a 12-bit ADC with 12 channels, dual 12-bit DACs, three configurable op-amps, and integrated 160-segment LCD driver with regulated charge pump - designed for portable medical devices and electronic metering applications requiring long battery life and analog signal conditioning.
For engineers reviewing the MSP430FG4619IZQWT datasheet, MSP430FG4619IZQWT pinout, MSP430FG4619IZQWT application, or MSP430FG4619IZQWT equivalent, key selection considerations include its MicroStar Junior™ BGA (113-ball) package, 80 I/O pins with LCD segment mapping, low-power operation down to 0.22 µA in RAM-retention mode, and dual USCI modules supporting UART/IrDA/SPI/I²C for sensor interface and display control.
Technical Context
The MSP430FG4619IZQWT implements a 16-bit RISC CPU with constant generators and hardware multiplier, enabling high code efficiency in battery-constrained systems. Its architecture integrates FLL+ for clock synthesis, DMA controller with three channels, and two independent 16-bit timers (Timer_A3 and Timer_B7) with capture/compare and shadow register support for precise timing and PWM generation.
It features dual USCI modules: USCI_A0 supports UART, IrDA, and SPI; USCI_B0 supports SPI and I²C. The on-chip LCD_A module drives up to 160 segments using internal charge-pump regulation, eliminating external bias components - critical for compact, low-BOM metering and medical displays.

FAQ
What is the package type and ball count for MSP430FG4619IZQWT?
The MSP430FG4619IZQWT uses the MicroStar Junior™ BGA package with 113 balls in a 7 mm × 7 mm body. It shares pinout compatibility with the ZCA variant but differs from the 100-pin LQFP (PZ) option. Ball pitch is 0.5 mm, and thermal pad (ball B3) must be connected to DVSS1 for optimal grounding per TI SLAS508K.
Does MSP430FG4619IZQWT support crystal oscillators for precise timing?
Yes, the MSP430FG4619IZQWT supports two crystal oscillators: LFXT1 (for 32.768 kHz watch crystals) on XIN/XOUT pins and XT2 (for 4–16 MHz standard crystals) on XT2IN/XT2OUT pins. Both are fully integrated with FLL+ for stable system clock generation and RTC operation.
How many LCD segments can MSP430FG4619IZQWT drive, and what voltage support does it provide?
The MSP430FG4619IZQWT drives up to 160 LCD segments using its integrated LCD_A module. It includes a regulated charge pump that generates internal LCD bias voltages (V1–V5), eliminating need for external voltage sources. LCDCAP requires a 2.2 µF ceramic capacitor for stable operation.
What communication interfaces are available on MSP430FG4619IZQWT?
The MSP430FG4619IZQWT features two universal serial communication interfaces: USCI_A0 (supporting UART, IrDA, and SPI) and USCI_B0 (supporting SPI and I²C). USART1 is also present for legacy UART/SPI functionality, providing redundant or parallel communication paths.
Is MSP430FG4619IZQWT suitable for safety-critical medical applications?
The MSP430FG4619IZQWT meets key requirements for Class II medical devices, including brownout detection, supply voltage supervisor (SVS), watchdog timer (WDT+), and programmable security fuse. However, final certification requires system-level validation per IEC 62304 and risk analysis - TI provides documentation support but not device-level safety certification.
