Product details
Overview
MSP430F4618IPZR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 116KB+256B Flash memory, 8KB 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), three-channel DMA, USCI_A0 (UART/IrDA/SPI), USCI_B0 (I²C/SPI), and USART1 (UART/SPI). It operates from 1.8 V to 3.6 V and targets portable medical devices and electronic metering systems.
For engineers reviewing the MSP430F4618IPZR datasheet, MSP430F4618IPZR pinout, MSP430F4618IPZR application, or MSP430F4618IPZR equivalent, key selection criteria include Flash/RAM capacity, integrated LCD drive capability, ADC resolution and channel count, low-power mode wake-up time (<6 µs), and compatibility with TI's MSP430 development ecosystem including MSP-FET430UIF and MSP-TS430PZ100.
Technical Context
The MSP430F4618IPZR implements the MSP430x461x family architecture with a 16-bit RISC CPUX core, hardware multiplier, FLL+ clock system, and five configurable low-power modes. Its ADC12 module supports 12-bit conversion across 12 analog inputs with internal/external reference selection and sample-and-hold functionality.
It integrates two independent universal serial interfaces: USCI_A0 supporting UART, IrDA, and SPI; USCI_B0 supporting I²C and SPI; plus a dedicated USART1 for asynchronous/synchronous communication. The LCD_A module delivers regulated charge-pump-based bias generation for static-to-4-mux segment driving.

FAQ
What is the maximum operating frequency of the MSP430F4618IPZR?
The MSP430F4618IPZR supports a maximum system clock (MCLK) frequency of 8 MHz using the XT2 oscillator with FLL+ multiplication. Its 125-ns instruction cycle time corresponds to 8 MHz operation, enabling responsive real-time control while maintaining ultralow power consumption in active mode.
Does the MSP430F4618IPZR include a hardware real-time clock (RTC)?
Yes, the MSP430F4618IPZR integrates a basic timer with real-time clock capability, driven by the 32.768 kHz XT1 crystal. This RTC function supports calendar timekeeping, alarm interrupts, and periodic wake-up events-essential for energy meter billing cycles and medical device scheduling.
How many LCD segments can the MSP430F4618IPZR drive, and what mux configurations are supported?
The MSP430F4618IPZR's LCD_A module drives up to 160 segments with 1-, 2-, 3-, or 4-mux configurations.
