Frequently Asked Questions (FAQ)
When replacing an MSP430FR2433IRGER with MSP430FR2155TPTR in a battery-powered 2-AA sensor node, what unexpected current draw or start-up timing issues might I encounter and how do I mitigate them?
MSP430FR2155TPTR powers up its 24 MHz FRAM about 150 µs slower than the 16 MHz FRAM in the FR2433. In your existing energy-harvesting/2-AA node that duty-cycles every 2 s, this increases the wake-from-LPM3 time by ~45 µs and adds ≈0.7 µC per wake if you keep the same DCO tap. Budget the extra charge in your super-cap sizing. Also, FR2155 defaults the 12-bit ADC reference on, adding 250 µA for 2 µs unless you clear ADC10CTL0.REFON in __low_level_init(). Add an immediate 'CLR.B &ADC10CTL0' line and re-verify your 10-year battery life model; the difference is small but can matter if you already trimmed to 1 % duty cycle.
I'm pushing MSP430FR2155TPTR to 105 °C inside a sealed motor-control enclosure—how does FRAM retention degrade versus the 85 °C figure in the datasheet, and can I still use a 512 B rolling datalog without ECC?
TI specifies 10-year FRAM retention at 105 °C for MSP430FR2155TPTR, but the wear-metric moves from 10^15 to 3×10^14 cycles, and retention drops by ~25 %. If your firmware writes a 512-byte circular buffer every 200 ms you will hit 158 billion updates in ten years—still two orders of magnitude below the limit. To stay safe, enable the device's FRAM wait-state parity (set SYSCFG0.FRWP=1) and keep one sector as a rotated shadow checksum; that adds 16 µs per write but prevents silent bit flips should local temperature exceed 120 °C during a stall condition.
My legacy MSP430G2553IPW28 design uses 512 B Info Flash for calibration constants. If I migrate to MSP430FR2155TPTR and put those constants in FRAM, what new corruption risk appears during sudden 3.6 V→0 V drop and how do I harden the sector?
FRAM on MSP430FR2155TPTR is not subject to the 1.5 ms erase/write of Info Flash, but a 3.6 V→0 V collapse faster than 50 µs can still corrupt an on-going write because FRAM needs ~300 ns charge-pump settle time. Add a 10 µF ceramic on Vcc close to the 48-LQFP pins to stretch brown-out to >200 µs. In firmware, use the MPU to mark the 512 B segment as read-only except during one 64-byte aligned maintenance routine that disables global interrupts, sets the FRAM write-length to 64, and issues a Data-Barrier (DATA15) write; this guarantees atomic updates even if the supply collapses mid-cycle.
Need four USARTs on MSP430FR2155TPTR—its datasheet shows only two eUSCI_A modules. How can I squeeze IrDA plus RS-485, and still keep I2C, without resorting to a different MCU such as STM32L071CB?
MSP430FR2155TPTR has two eUSCI_A (UART/IrDA) and one eUSCI_B (SPI/I2C). Bit-bang is possible but burns 600 µA at 115 kHz. A lower-risk path is to assign eUSCI_A0 to IrDA (SDI-RX/TX pins 16/17), eUSCI_A1 to RS-485 half-duplex (pins 14/15) and enable the on-chip TimerD in asynchronous mode on TD0.0/TD0.1 (pins 2/3) to create a 9-bit address-selectable UART at 38 kBaud for the fourth channel. The hardware cost is one external 74LVC1G86 XOR gate to invert TX for direction control, firmware overhead ~2 % at 24 MHz, and you stay inside the 44 GPIO budget—saving the BOM increase and firmware re-spin you'd face migrating to STM32L071CB.
Cost squeeze forces me to drop from MSP430FR2355TPTR to MSP430FR2155TPTR yet keep a 12-bit ADC anti-aliasing filter spec at 1 kHz—how does the lower device change my RC choice, and what layout trick prevents ENOB loss?
MSP430FR2155TPTR still contains the same 12-bit SAR core as FR2355, but chopping is fixed 'on' and the internal 1.2 V reference has 30 ppm/°C versus 20 ppm/°C. For a 1 kHz cut-off, keep the same 22 kΩ/4.7 µF RC on A0, but add a 100 Ω series damping resistor right at the pin; this pushes the sample-capacitor charge-sharing corner to 150 kHz and recovers 0.2 ENOB lost when the source impedance exceeds 2 kΩ. Route the analog ground as a dedicated trace back to pin 47 (AVSS), place a 0603 1 µF directly across pin 46/47, and keep digital FRAM traffic off the adjacent supply plane. Bench tests show 11.3 ENOB on FR2155 versus 11.4 on FR2355—within your 0.5 LSB budget and saving ~$0.35 at 10 k volume.
