For engineers reviewing the MSP430FR6887IPZ datasheet, MSP430FR6887IPZ pinout, MSP430FR6887IPZ application, or MSP430FR6887IPZ equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (0.35 µA typical), 100-pin LQFP package compatibility, and integrated capacitive touch I/O across all ports P1–P10 and PJ.

Technical Context

The MSP430FR6887IPZ implements the MSP430 CPUXV2 core with 16 registers and supports seven low-power modes optimized for energy-constrained deployments. Its FRAM architecture enables unified memory space for code, data, and storage - eliminating separate flash/EEPROM partitions and enabling atomic writes without erase cycles.

Peripherals include dual eUSCI_A (UART/IrDA/SPI) and dual eUSCI_B (I²C/SPI) modules, three 16-bit Timer_A instances (TA0/TA1/TA3), two Timer_B units (TB0/TB1), 32-bit hardware multiplier, CRC16/CRC32 engines, and a 16-channel analog comparator. The device integrates an on-chip LDO, SVS, and programmable pullup/pulldown on all I/O pins.

FAQ

What is the FRAM endurance specification for the MSP430FR6887IPZ?

The MSP430FR6887IPZ features 10¹⁵ write cycle endurance for its 128KB FRAM. This means each memory location can be written to approximately one quadrillion times - far exceeding flash-based MCUs and eliminating wear-out concerns in high-frequency logging applications like smart metering. The MSP430FR6887IPZ leverages this to enable reliable, maintenance-free operation over 10+ years.

Does the MSP430FR6887IPZ support capacitive touch sensing without external components?

Yes, the MSP430FR6887IPZ supports capacitive touch sensing on all I/O pins across ports P1–P10 and PJ. This is implemented via integrated charge-transfer circuitry and requires no external RC networks or dedicated touch controller ICs. The MSP430FR6887IPZ uses this capability to enable sealed, low-cost user interfaces in utility meters and portable devices.

What is the lowest active power consumption of the MSP430FR6887IPZ at 16 MHz?

At 16 MHz and 3.0 V supply, the MSP430FR6887IPZ consumes approximately 100 µA/MHz in Active Mode, equating to ~1.6 mA total. This value is measured excluding external peripheral current and reflects the efficiency of the FRAM-based architecture and optimized CPUXV2 core. The MSP430FR6887IPZ maintains this efficiency across its full 1.8–3.6 V operating range.

Which crystal frequencies are supported by the MSP430FR6887IPZ clock system?

The MSP430FR6887IPZ supports both low-frequency (32.768 kHz) and high-frequency crystals via dedicated LFXT and HFXT oscillators. It also includes a factory-trimmed DCO with 10 selectable frequencies and a low-power VLO source. The MSP430FR6887IPZ uses these to drive ACLK, MCLK, and SMCLK independently - enabling precise RTC timing and flexible system clocking.

Is the MSP430FR6887IPZ pin-compatible with other devices in the MSP430FR687x family?

Yes, the MSP430FR6887IPZ shares the same 100-pin LQFP (PZ) package and pinout as MSP430FR6879IPZ and MSP430FR6877IPZ. Signal mapping, power domains, and peripheral multiplexing are identical across these variants. The MSP430FR6887IPZ can be substituted in existing designs targeting the same package, provided FRAM size and BSL type meet application requirements.
