Product details
Overview
MSP430F4616IPZ from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 92KB+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 MSP430F4616IPZ datasheet, MSP430F4616IPZ pinout, MSP430F4616IPZ application, or MSP430F4616IPZ equivalent, key selection criteria include its 100-pin TQFP package, ADC12 module presence, LCD charge-pump regulation, wake-up time under 6 µs, and support for UART/I²C/SPI via dual USCI modules.
Technical Context
The MSP430F4616IPZ implements the MSP430x461x family architecture with CPUX core, FLL+ frequency-locked loop, and hardware multiplier. Its ADC12 module supports 12-bit resolution, internal reference, sample-and-hold, and autoscan across 12 channels - confirmed for the 'x461x' (non-'x461x1') variant. The device integrates two independent USCI modules: USCI_A0 supporting UART/IrDA/SPI and USCI_B0 supporting SPI/I²C.
It features dual power domains (DVCC1/DVCC2, AVCC/AVSS) with dedicated analog and digital supply pins, SVS/SVM brownout detection with programmable threshold, and JTAG-based debugging via TCK/TMS/TDI/TDO. The LCD_A peripheral includes regulated charge pump and supports 1–4 multiplex configurations with COM0–COM3 backplanes and up to 160 segments.

FAQ
Does the MSP430F4616IPZ include the ADC12 module?
Yes, the MSP430F4616IPZ includes the full ADC12 module with 12-bit resolution, internal reference, sample-and-hold, and autoscan capability. This is confirmed by its membership in the MSP430x461x (not x461x1) family, where ADC12 is implemented. The MSP430F4616IPZ datasheet explicitly lists ADC12CLK on pin P2.7 and analog inputs A0–A15 across multiple port pins.
What is the maximum LCD segment count supported by the MSP430F4616IPZ?
The MSP430F4616IPZ supports up to 160 LCD segments using its integrated LCD_A peripheral with 1–4 multiplexing and regulated charge pump. This is achieved via 40 segment outputs (S0–S39), 4 common backplanes (COM0–COM3), and programmable voltage levels (V1–V5) - all documented in the functional block diagram and terminal functions table for the MSP430x461x series.
Is the MSP430F4616IPZ pin-compatible with other devices in the MSP430x461x family?
Yes, the MSP430F4616IPZ is pin-compatible with MSP430F4617IPZ, MSP430F4618IPZ, and MSP430F4619IPZ in the 100-pin TQFP (PZ) package. All share identical pin numbering, electrical characteristics, and peripheral mapping - enabling direct substitution where memory requirements align, as confirmed in the "Available Options" section of the SLAS675 datasheet.
What debug interfaces does the MSP430F4616IPZ support?
The MSP430F4616IPZ supports standard 4-wire JTAG (TCK/TMS/TDI/TDO) for full-speed emulation, programming, and boundary-scan testing. It also supports Spy-Bi-Wire (2-wire JTAG) via TCLK/TDI for space-constrained designs. Both interfaces are enabled by the integrated Embedded Emulation Module (EEM) and are compatible with TI's MSP-FET430UIF and MSP-FET430PIF debuggers.
Does the MSP430F4616IPZ support real-time clock functionality?
Yes, the MSP430F4616IPZ includes a Basic Timer module with real-time clock (RTC) capability, supporting calendar mode with seconds/minutes/hours/days/months/year counters and alarm interrupts. This is implemented using the ACLK source (e.g., 32.768 kHz crystal on XIN/XOUT) and requires no external RTC IC - a key feature highlighted in the device description and functional block diagram.
