Product details
Overview
MSP430F47193IPZ from Texas Instruments is an ultralow-power mixed-signal microcontroller designed for precision electricity metering applications. It integrates 120KB Flash, 4KB RAM, three 16-bit sigma-delta ADCs with differential PGA inputs, a 160-segment LCD driver, and four USCI modules supporting UART, IrDA, SPI, and I²C - enabling single-phase and poly-phase watt-hour meter implementations.
For engineers reviewing the MSP430F47193IPZ datasheet, MSP430F47193IPZ pinout, MSP430F47193IPZ application, or MSP430F47193IPZ equivalent, key selection criteria include its 100-pin QFP package, 1.8–3.6 V supply range, 350 µA active current at 1 MHz/2.2 V, RAM-retentive 0.2 µA off-mode, and dedicated metrology-grade analog front-end with programmable gain.
Technical Context
The MSP430F47193IPZ implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and three-channel internal DMA to support concurrent high-precision ADC sampling and real-time data processing. Its SD16_A module provides three independent 16-bit sigma-delta converters, each with differential input pairs and selectable PGA gain, directly optimized for current/voltage sensing in revenue-grade energy meters.
Power management is handled via five software-selectable low-power modes, including LPM4 (0.2 µA) with RAM retention and sub-6 µs wake-up latency. The integrated Basic Timer with real-time clock capability and hardware multiplier enable time-stamped energy accumulation and billing calculations without external components.

FAQ
What is the maximum operating frequency of the MSP430F47193IPZ CPU?
The MSP430F47193IPZ features a 16-bit RISC CPU with a 62.5-ns instruction cycle time, corresponding to a maximum system clock frequency of 16 MHz. This timing is achieved using the integrated digitally controlled oscillator (DCO) or external crystal sources, and supports deterministic execution for metrology algorithms requiring precise sample intervals.
Does the MSP430F47193IPZ support hardware-based cryptographic functions?
The MSP430F47193IPZ does not include dedicated cryptographic accelerators such as AES or SHA engines. However, it provides programmable code protection via a security fuse and supports secure bootloader implementation through its bootstrap loader and flash memory write-protection features - sufficient for basic firmware authentication in utility-grade meters.
How many analog input channels does the MSP430F47193IPZ support for sigma-delta conversion?
The MSP430F47193IPZ supports exactly three independent 16-bit sigma-delta analog-to-digital converter channels (SD16_A), each with differential input pairs (A0.0±, A1.0±, A2.0±) and programmable gain amplifier stages. This matches the "x3" suffix in its part number and is confirmed in the device family documentation SLAS626C.
What is the function of the LCDCAP/R33 pin on the MSP430F47193IPZ?
The LCDCAP/R33 pin on the MSP430F47193IPZ serves as the connection point for the external capacitor used by the integrated LCD charge pump circuit. It also functions as the most positive analog voltage level (V1) output for LCD bias generation, enabling direct drive of up to 160 segments without external voltage dividers or regulators.
Can the MSP430F47193IPZ operate from a single 3.3 V supply without level shifters?
Yes, the MSP430F47193IPZ operates over a supply range of 1.8 V to 3.6 V, making it fully compatible with standard 3.3 V system rails. All I/O pins are 3.3 V tolerant, and internal voltage regulators manage DVCC1/DVCC2 and AVCC domains - eliminating the need for external level shifters in typical meter designs.
