Product details
Overview
MSP430F4619IPZR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 120KB+256B Flash memory, 4KB RAM, a 12-bit ADC (MSP430x461x variant), integrated LCD driver for up to 160 segments, dual 16-bit timers (Timer_A3 and Timer_B7), USCI_A0/USCI_B0 serial interfaces, and DMA controller. It operates from 1.8 V to 3.6 V and targets portable medical devices and electronic metering applications.
For engineers reviewing the MSP430F4619IPZR datasheet, MSP430F4619IPZR pinout, MSP430F4619IPZR application, or MSP430F4619IPZR equivalent, key selection criteria include Flash/RAM size, ADC presence and channel count, LCD segment drive capability, USCI peripheral configuration (UART/I²C/SPI), and TQFP-100 package compatibility with high-pin-count sensor or display subsystems.
Technical Context
The MSP430F4619IPZR implements the MSP430x461x family architecture with a 16-bit RISC CPU, constant generators, and five low-power modes optimized for battery longevity. Its FLL+ module enables sub-6 µs wake-up from standby mode using internal DCO or external crystal sources (XT1/XT2).
It integrates dedicated hardware blocks including a 12-bit ADC12 with internal reference and autoscan, LCD_A controller with regulated charge pump, and two independent universal serial communication interfaces-USCI_A0 supporting UART/IrDA/SPI and USCI_B0 supporting SPI/I²C-enabling concurrent wired and wireless interface management in resource-constrained systems.

FAQ
Does the MSP430F4619IPZR include a 12-bit ADC?
Yes, the MSP430F4619IPZR includes the ADC12 module with 12-bit resolution, 12 input channels, internal reference, sample-and-hold, and autoscan capability. This is confirmed in the MSP430x461x family datasheet (SLAS675) and distinguishes it from the MSP430x461x1 variants where ADC12 is omitted. The MSP430F4619IPZR is part of the MSP430x461x (not x461x1) series.
What is the maximum number of LCD segments supported by the MSP430F4619IPZR?
The MSP430F4619IPZR supports up to 160 LCD segments using its integrated LCD_A controller with 1–4 multiplexing. This capability is enabled by 32 segment outputs (S0–S39), four common outputs (COM0–COM3), and programmable charge pump regulation - all documented in the functional block diagram and terminal functions table of SLAS675.
Which serial communication protocols does the MSP430F4619IPZR support natively?
The MSP430F4619IPZR supports UART, IrDA, SPI, and I²C natively via two independent USCI modules: USCI_A0 (configurable for UART/IrDA/SPI) and USCI_B0 (configurable for SPI/I²C). These are hardware-peripheral implementations - not software bit-banged - and are verified in the "Functional Block Diagram" and "Terminal Functions" sections of SLAS675.
What package type and pin count does the MSP430F4619IPZR use?
The MSP430F4619IPZR uses a 100-pin plastic TQFP (PZ) package with 0.5 mm pitch, as specified in the "Available Options" table of SLAS675. Pin assignments match the MSP430x461xIPZ pin designation diagram (pages 3–4), confirming full compatibility with standard 100-pin TQFP footprints and routing guidelines.
How much Flash and RAM memory does the MSP430F4619IPZR provide?
The MSP430F4619IPZR provides 120KB+256B of Flash memory and 4KB of RAM, as explicitly listed under "Family Members Include" in SLAS675. This memory configuration is unique to the MSP430x4619/x46191 variants and exceeds the Flash capacity of MSP430F4616IPZ (92KB), MSP430F4617IPZ (92KB), and MSP430F4618IPZ (116KB).
