Texas Instruments MSP430F5328TRGCTEP

Overview

MSP430F5328TRGCTEP from Texas Instruments is an extended-temperature, radiation-tolerant mixed-signal microcontroller featuring a 16-bit RISC CPU, 128 KB flash, 10 KB RAM (8 KB + 2 KB), 12-bit ADC with autoscan, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), integrated 3.3-V LDO, and real-time clock - deployed in space-grade sensor telemetry and battery-powered industrial monitoring systems.

For engineers reviewing the MSP430F5328TRGCTEP datasheet, MSP430F5328TRGCTEP pinout, MSP430F5328TRGCTEP application, or MSP430F5328TRGCTEP equivalent, key selection criteria include its –40°C to +105°C operation, LPM3 standby current of 1.9 µA at 3 V, 47 GPIOs in 64-pin VQFN (RGC), integrated power management with programmable LDO, and radiation-hardened EP-grade qualification per V62/13628-01XE.

Technical Context

The MSP430F5328TRGCTEP implements a unified clock system with FLL-based frequency stabilization, supporting up to 25 MHz system clock via XT2 (32 MHz max), DCO, REFO, and VLO sources. Its low-power architecture enables wake-up from LPM3 in 3.5 µs (typical) using ACLK or RTC-triggered interrupts.

Peripheral integration includes three-channel DMA for zero-CPU-overhead data movement between ADC, USCI, and memory; port mapping controller enabling dynamic reassignment of secondary functions on P4 pins; and hardware multiplier supporting 32-bit operations - all coordinated under a flexible power management system with programmable core voltage regulation.

FAQ

What is the operating temperature range of the MSP430F5328TRGCTEP?

The MSP430F5328TRGCTEP is rated for continuous operation from –40°C to +105°C and fully characterized across this range per MIL-PRF-38535 Class V requirements. Key parameters including LPM3 current (2.1 µA at 3 V), ADC performance, and timer accuracy are validated at both extremes, making it suitable for deployment in engine compartments, downhole tools, and low-earth-orbit satellites.

Does the MSP430F5328TRGCTEP include an integrated voltage regulator?

Yes, the MSP430F5328TRGCTEP integrates a fully programmable LDO that accepts 3.3 V ±10% on LDOI and delivers a stable 3.3 V core supply on LDOO. This eliminates the need for an external regulator, reduces BOM count, and improves power efficiency in battery-operated systems - especially critical in LPM3 and LPM4 modes where supply supervision remains active.

How many analog input channels does the MSP430F5328TRGCTEP support?

The MSP430F5328TRGCTEP supports 12 analog input channels: 10 external (A0–A9) and 2 internal (VeREF+ and VeREF−). The 12-bit ADC includes sample-and-hold, internal reference selection (1.5 V or 2.5 V), and autoscan mode - enabling sequential conversion of multiple sensors without CPU intervention, ideal for multi-parameter environmental monitoring.

What debug interfaces are supported by the MSP430F5328TRGCTEP?

The MSP430F5328TRGCTEP supports three debug interfaces: standard 4-pin JTAG (PJ.0–PJ.3 + TEST/SBWTCK + RST/NMI/SBWTDIO), two-wire Spy-Bi-Wire (RST/NMI/SBWTDIO + TEST/SBWTCK), and UART-based Bootstrap Loader (BSL) using P1.1/P1.2. All are accessible in the 64-pin RGC package and retain full functionality across the –40°C to +105°C range.

Is the MSP430F5328TRGCTEP pin-compatible with other MSP430F53xx devices?

Yes, the MSP430F5328TRGCTEP is pin-compatible with MSP430F5329TRGCTEP and MSP430F5319TRGCTEP in the 64-pin RGC package. All share identical pin functions, electrical characteristics, and thermal pad layout - enabling drop-in memory upgrades (e.g., 128 KB → 144 KB flash) without PCB redesign or firmware changes beyond linker script updates.
