Product details
Overview
MSP430F4619IPZ from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 120KB+256B Flash/ROM, 4KB RAM, a 12-bit ADC with internal reference and autoscan, integrated LCD driver for up to 160 segments, dual 16-bit timers (Timer_A3 and Timer_B7), USCI_A0 (UART/IrDA/SPI), USCI_B0 (I²C/SPI), DMA controller with three channels, and hardware multiplier - deployed in portable medical devices and electronic metering systems.
For engineers reviewing the MSP430F4619IPZ datasheet, MSP430F4619IPZ pinout, MSP430F4619IPZ application, or MSP430F4619IPZ equivalent, key selection criteria include Flash/RAM size, ADC channel count and resolution, LCD segment drive capability, USCI peripheral flexibility (I²C/UART/SPI/IrDA), and low-power mode wake-up latency under 6 µs.
Technical Context
The MSP430F4619IPZ implements a 16-bit RISC CPUX core with constant generators and 16 general-purpose registers, enabling single-cycle register operations and high code efficiency. Its FLL+ system provides stable clock generation with digital control, supporting MCLK, SMCLK, and ACLK domains derived from XT1 (32.768 kHz watch crystal) and XT2 (up to 8 MHz standard crystal).
It integrates two independent universal serial interfaces: USCI_A0 supports UART (with auto-baud detection), IrDA encoding/decoding, and SPI; USCI_B0 supports I²C master/slave and SPI. The 12-bit ADC12 module includes 12 input channels, sample-and-hold, internal reference (1.5 V/2.0 V/2.5 V), and conversion trigger via timer or external signal.

FAQ
What is the maximum operating frequency of the MSP430F4619IPZ?
The MSP430F4619IPZ supports a maximum system clock (MCLK) frequency of 8 MHz using the XT2 oscillator. Its CPU executes instructions at 125-ns cycle time, enabling deterministic real-time performance for time-critical metering and medical functions. The FLL+ module dynamically adjusts DCO frequency to maintain stability across voltage and temperature variations.
Does the MSP430F4619IPZ include a hardware AES accelerator?
No, the MSP430F4619IPZ does not include a hardware AES accelerator. It relies on software-based cryptographic libraries for security functions. For applications requiring hardware encryption, consider TI's MSP430FR59xx or MSP432P4xx families. The MSP430F4619IPZ does provide programmable code protection via security fuse and brownout detection to prevent unauthorized access during voltage glitch attacks.
How many LCD segments can the MSP430F4619IPZ drive, and what bias configurations are supported?
The MSP430F4619IPZ drives up to 160 LCD segments with 1/2, 1/3, or 1/4 duty and 1/2 or 1/3 bias. It includes a regulated charge pump (LCDCPEN) for generating VLCD from DVCC, eliminating need for external bias supplies. Segments S0–S3 are disabled when charge pump is enabled, per device specification.
Is the ADC12 module present in the MSP430F4619IPZ?
Yes, the MSP430F4619IPZ includes the full ADC12 module with 12 input channels, internal reference (1.5 V/2.0 V/2.5 V), sample-and-hold, and autoscan functionality. This distinguishes it from the MSP430F46191IPZ variant, which omits the ADC12 module entirely. The ADC12CLK input (P2.7) allows external synchronization of conversions.
What development tools are recommended for programming and debugging the MSP430F4619IPZ?
Texas Instruments recommends the MSP-FET430UIF (USB JTAG emulator), MSP-TS430PZ100 (target socket board for 100-pin TQFP), and Code Composer Studio IDE. The device includes an Embedded Emulation Module (EEM) supporting real-time debugging, flash breakpoints, and low-power mode profiling - essential for optimizing energy consumption in battery-powered MSP430F4619IPZ applications.
