Texas Instruments MSP430F47196IPZ

Overview

MSP430F47196IPZ from Texas Instruments is an ultralow-power mixed-signal microcontroller designed for poly-phase electricity metering applications. It integrates 120KB Flash, 4KB RAM, six 16-bit sigma-delta ADCs with differential PGA inputs, a 16-bit RISC CPU, four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), and an integrated LCD driver supporting up to 160 segments - enabling single-chip implementation of Class 0.2/0.5 energy meters.

For engineers reviewing the MSP430F47196IPZ datasheet, MSP430F47196IPZ pinout, MSP430F47196IPZ application, or MSP430F47196IPZ equivalent, key selection criteria include its six-channel high-precision ADC architecture, 100-pin QFP package with dedicated analog input pairs (A0.0± through A5.0±), real-time clock capability, and support for E-meter reference design SLAA409.

Technical Context

The MSP430F47196IPZ implements a 16-bit RISC CPU with constant generators and 62.5-ns instruction cycle time, paired with three-channel internal DMA to offload ADC data transfers. Its FLL+ system enables sub-6-µs wake-up from LPM4 using ACLK from external crystals (XT1/XT2) or internal DCO.

It features two independent 16-bit timers (Timer_A3 and Timer_B3), each with capture/compare registers and shadow functionality, plus a basic timer with RTC mode. The SD16_A module supports programmable gain amplification and differential input configurations across all six ADC channels - critical for simultaneous voltage/current sampling in three-phase metering topologies.

The following parts are listed as comparable options for similar mixed-signal microcontroller applications.

Compared with MSP430F47186IPZ, the MSP430F47196IPZ trades RAM capacity for lower cost and identical Flash size, making it optimal for fixed-function metering firmware. Against MSP430F47197IPZ, it reduces pin count and die area by omitting the seventh ADC channel - lowering BOM cost where auxiliary sensing is unnecessary.

FAQ

What is the maximum sampling rate supported by the six sigma-delta ADCs in the MSP430F47196IPZ?

The MSP430F47196IPZ SD16_A module supports up to 128 ksps aggregate throughput across all six channels when configured for 13-bit resolution. At full 16-bit resolution, typical effective sampling rates range from 1.5 ksps to 8 ksps per channel depending on oversampling ratio and filter settings - sufficient for 50/60 Hz power system measurements with harmonic analysis up to the 40th order. Each channel operates independently with configurable conversion triggers.

Does the MSP430F47196IPZ support hardware-accelerated metrology calculations such as RMS or fundamental frequency extraction?

Yes, the MSP430F47196IPZ includes a 32-bit hardware multiplier with MAC (multiply-accumulate) instructions that accelerate fixed-point arithmetic for RMS, active/reactive power, and harmonic computations. While no dedicated metrology co-processor is present, the combination of DMA-driven ADC data flow, timer-synchronized sampling, and optimized instruction set enables real-time calculation of IEC 61000-4-30 compliant parameters within firmware - validated in TI's SLAA409 three-phase watt-hour meter reference design.

Can the MSP430F47196IPZ drive a 160-segment LCD without external components?

Yes, the MSP430F47196IPZ integrates a full-featured LCD_A peripheral supporting up to 160 segments with internal charge pump, contrast control register (LCDCON), and programmable bias generation. It drives common outputs (COM0–COM3) and segment outputs (S0–S39) directly - eliminating external LCD bias ICs and reducing bill-of-materials. The LCDCAP pin connects to an external capacitor to stabilize the internal charge pump voltage for stable contrast across temperature and supply variations.

What crystal configurations are supported for timekeeping and system clocking on the MSP430F47196IPZ?

The MSP430F47196IPZ supports dual crystal oscillators: XT1 accepts 32.768 kHz watch crystals for low-power real-time clock operation in LPM3/LPM4 modes, while XT2 supports 4–16 MHz standard crystals for high-accuracy system clocking and ADC sampling synchronization. Both oscillators are independently controlled and can be selected via software-configurable FLL+ loop settings - enabling precise timekeeping during sleep and jitter-free sampling during active metrology cycles.

Is the MSP430F47196IPZ pin-compatible with other devices in the MSP430F471xx family?

Yes, the MSP430F47196IPZ shares identical 100-pin QFP (PZ) packaging and pin mapping with all MSP430F471x6 variants, including MSP430F47126IPZ, MSP430F47166IPZ, and MSP430F47186IPZ. Pin functions for power, reset, JTAG, USCI, timers, and LCD are fully aligned. Analog input pins A0.0± through A5.0± are consistently assigned across all x6 variants, enabling hardware reuse across different Flash/RAM configurations in meter platform designs.
