Product details
Overview
MSP430FR6877IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64KB ferroelectric RAM (FRAM), 2KB SRAM, 12-bit ADC with 16 external inputs, integrated LCD driver supporting up to 320 segments, and real-time clock with calendar function. It operates from 1.8 V to 3.6 V and targets battery-powered metering applications requiring long-term data retention and low active/standby current.
For engineers reviewing the MSP430FR6877IPZ datasheet, MSP430FR6877IPZ pinout, MSP430FR6877IPZ application, or MSP430FR6877IPZ equivalent, key selection criteria include FRAM endurance (1015 write cycles), LPM3.5 RTC current (0.35 µA typical), 100-pin LQFP package compatibility, and support for capacitive touch I/O without external components.
Technical Context
The MSP430FR6877IPZ implements the MSP430 CPUXV2 core with 16 registers and integrates three independent Timer_A modules (TA0, TA1, TA3), two Timer_B modules (TB0, TB1), and dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (I²C/SPI) peripherals. Its FRAM memory architecture enables byte-level writes at 125 ns/word with no erase-before-write overhead.
Power management includes seven low-power modes (LPM0–LPM4.5), SVS brownout detection, and programmable pullup/pulldown on all I/O ports. The device supports crystal oscillators (LFXT/HFXT), internal DCO with 10 factory-trimmed frequencies, and VLO for ultra-low-power standby operation.
Key Specifications

Does the MSP430FR6877IPZ support hardware encryption?
No, the MSP430FR6877IPZ does not include dedicated AES or SHA hardware accelerators. However, it provides a true random number seed generator for cryptographic algorithm initialization and supports secure boot via its hardware bootloader (BSL) with password protection - features confirmed in the SLASE33C datasheet Section 6.5.
How many I/O pins does the MSP430FR6877IPZ have, and which support capacitive touch?
The MSP430FR6877IPZ has 83 general-purpose I/O pins in its 100-pin LQFP package. All pins across ports P1–P10 and PJ support capacitive touch sensing without external components, as verified in the "Multifunction Input/Output Ports" section of the SLASE33C datasheet and confirmed by TI's CTSI documentation.
What LCD configuration does the MSP430FR6877IPZ support?
The MSP430FR6877IPZ integrates the LCD_C module supporting up to 320 segments with static, 2–8 multiplex configurations. It generates internal LCD bias voltages (V1–V5) and provides dedicated COM0–COM7 outputs on P6.x and P2.x pins - eliminating external charge pumps or resistor networks per TI SLASE33C Section 1.1.
Is the MSP430FR6877IPZ pin-compatible with other devices in the MSP430FR687x family?
Yes, the MSP430FR6877IPZ shares identical pinout and electrical characteristics with the MSP430FR6879IPZ and MSP430FR68791IPZ in the 100-pin LQFP (PZ) package, as confirmed in TI's Device Comparison Table 3-1 and Pin Diagram Figure 4-1.
