Product details
Overview
MSP430F4783IPZ from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller designed for single-phase electricity metering applications. It integrates three 16-bit sigma-delta ADCs with differential PGA inputs, 48KB flash + 256B information memory, 2KB RAM, and an on-chip LCD driver supporting up to 160 segments - all operating within 1.8 V to 3.6 V supply range.
For engineers reviewing the MSP430F4783IPZ datasheet, MSP430F4783IPZ pinout, MSP430F4783IPZ application, or MSP430F4783IPZ equivalent, key selection considerations include its triple sigma-delta ADC architecture, 100-pin QFP package with LCD segment mapping, low-power operation (0.2 μA in off mode), and integrated USCI_A/B modules supporting UART, IrDA, SPI, and I²C.
Technical Context
The MSP430F4783IPZ implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and five software-selectable low-power modes, enabling sub-6-μs wake-up from standby. Its FLL+ clock system supports dual crystal oscillators (XT1 at 32.768 kHz and XT2 up to 16 MHz) and generates MCLK, SMCLK, and ACLK with programmable division.
Peripherals include two 16-bit timers (Timer_A3 with three capture/compare registers; Timer_B3 with three capture/compare plus shadow registers), four USCI modules (two UART/IrDA/SPI and two SPI/I²C), a comparator, hardware multiplier, brownout detector, and supply voltage supervisor with programmable threshold detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators; enables high code efficiency and deterministic timing for metering firmware. |
| Flash / RAM | 48KB + 256B flash memory and 2KB RAM - sufficient for full metrology algorithm, communication stack, and LCD UI code. |
| ADC Configuration | Three independent 16-bit sigma-delta ADCs with differential PGA inputs - supports simultaneous voltage/current/neutral channel sampling in energy meters. |
| Power Consumption | 0.2 μA in off mode (RAM retention); 1.1 μA in standby; 280 μA active at 1 MHz/2.2 V - extends battery life in portable or backup-powered meters. |
