Texas Instruments MSP430F4618IPZ

Overview

MSP430F4618IPZ 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), USCI_A0 (UART/IrDA/SPI), USCI_B0 (I²C/SPI), and hardware DMA. It operates from 1.8 V to 3.6 V and targets battery-powered portable medical devices and electronic metering systems.

For engineers reviewing the MSP430F4618IPZ datasheet, MSP430F4618IPZ pinout, MSP430F4618IPZ application, or MSP430F4618IPZ equivalent, key selection criteria include Flash/RAM capacity, integrated LCD driver capability, ADC channel count and resolution, low-power mode wake-up time (<6 µs), and TQFP-100 package compatibility with high I/O density requirements.

Technical Context

The MSP430F4618IPZ implements the MSP430x461x family architecture with a 16-bit RISC CPUX core, constant generators, and FLL+ frequency locking loop enabling sub-6-µs wake-up from standby. Its memory-mapped peripherals include dual timer modules with capture/compare shadow registers (Timer_B7 supports seven CCRs with shadowing), and a dedicated ADC12 module with 12 channels, sample-and-hold, and internal 2.5-V reference.

It integrates two independent universal serial communication interfaces: USCI_A0 supporting UART, IrDA, and SPI; and USCI_B0 supporting I²C and SPI. The LCD_A module provides regulated charge-pump-based bias generation and direct drive for multiplexed LCDs up to 4-backplane × 40-segment or 2-backplane × 80-segment configurations.

FAQ

What is the maximum operating frequency of the MSP430F4618IPZ?

The MSP430F4618IPZ supports a maximum CPU clock frequency of 8 MHz via its FLL+ module. Its instruction cycle time is 125 ns at this speed. The device achieves this using the digitally controlled oscillator (DCO) locked to external crystals (XT1 or XT2) or internal reference, enabling precise timing control while maintaining ultralow power consumption in active mode.

Does the MSP430F4618IPZ include an integrated ADC, and what are its key specifications?

Yes, the MSP430F4618IPZ includes a 12-bit ADC12 module with 12 input channels, internal 2.5-V reference, sample-and-hold, and autoscan capability. It supports conversion rates up to 200 ksps and features configurable memory buffers, burst conversion mode, and hardware-triggered sampling - all fully supported in the MSP430F4618IPZ variant per the SLAS675 datasheet.

What LCD configurations does the MSP430F4618IPZ support, and how many segments can it drive?

The MSP430F4618IPZ integrates the LCD_A module capable of driving up to 160 segments with 1–4 backplanes. It supports static, 2-, 3-, and 4-mux configurations. The regulated charge pump generates required bias voltages internally, eliminating external components. Segment outputs (S0–S39) and COM0–COM3 are mapped to specific pins as defined in the pinout table for MSP430F4618IPZ.

Is the MSP430F4618IPZ pin-compatible with other devices in the MSP430x461x family?

Yes, the MSP430F4618IPZ is pin-compatible with MSP430F4616IPZ, MSP430F4617IPZ, and MSP430F4619IPZ in the 100-pin TQFP (PZ) package. All share identical pin assignments, electrical characteristics, and peripheral mappings - enabling hardware reuse across variants differentiated primarily by memory size and ADC inclusion.

What development tools are recommended for programming and debugging the MSP430F4618IPZ?

Texas Instruments recommends the MSP-FET430UIF (USB interface) or MSP-FET430PIF (parallel port) for debugging and programming the MSP430F4618IPZ. For evaluation, the MSP-TS430PZ100 target board provides socketed support for the 100-pin TQFP package, and the MSP-FET430U100 combines debugger and target board in one unit - all fully compatible with MSP430F4618IPZ's JTAG interface.
