MSP430FR6989IPZ - 16-bit ULP FRAM MCU 128KB | TI LQFP-100
MPN: MSP430FR6989IPZ ✓ Hoạt độngMSP430FR6989IPZ Tóm tắt
An FRAM-based microcontroller is a mixed-signal MCU whose non-volatile memory uses Ferroelectric RAM rather than flash. FRAM delivers nearly unlimited write endurance (roughly 100x more than flash), faster unified-memory writes at low energy, and a simpler software model because code and data share one address space. The MSP430 FRAM platform combines this memory with TI's holistic ultra-low-power system architecture, allowing designers to log data or run frequent writes without the wear-budget anxiety associated with flash. In the broader hierarchy, this device is a microcontroller -> embedded MCU -> mixed-signal SoC -> semiconductor.
Key specifications include 128 KB of non-volatile FRAM, 2 KB of information FRAM, 16 KB of SRAM, a 12-bit SAR ADC with up to 16 channels, four 16-bit timers, up to 83 GPIO pins, a real-time clock, and a 320-segment LCD driver. The integrated extended scan interface is purpose-built for liquid flow-meter rotary sensing, while the AES-128 hardware accelerator supports encrypted metering and secure connectivity.
The MSP430FR6989IPZ leverages TI's MSP430 CPUXV2 architecture with active current of approximately 118 uA/MHz and standby current under 1 uA with RTC retention, enabling multi-year battery life in metering and sensor applications. The unified FRAM memory can be partitioned at runtime between code and data, simplifying field firmware updates and over-the-air data logging. Built-in BSL and JTAG/SBW interfaces simplify in-system programming.
Typical applications include water, heat, and gas flow meters with rotary sensing, portable medical and industrial sensor loggers, secure battery-powered IoT endpoints, e-paper / LCD human-machine interfaces, and energy-harvesting wireless sensor nodes where its ultra-low-power modes and FRAM endurance deliver measurable system-level advantages.
When designing with this MCU, allocate the FRAM memory between code and data carefully - because writes are nearly instantaneous and unlimited, data-logging applications can reserve large blocks for circular buffers, but be sure to budget enough FRAM for firmware images so that in-field updates remain possible.

Ứng dụng tiêu biểu
MSP430FR6989IPZ phù hợp cho 6 Áp dụngs: Water and Heat Flow Meters, Portable Medical and Health Monitors, Industrial Sensor Loggers, Battery-Powered IoT Edge Nodes, LCD Human-Machine Interfaces, Energy-Harvesting Wireless Sensor Nodes.
Water and Heat Flow Meters
The MSP430FR6989IPZ is purpose-built for battery-powered water, heat, and gas flow meters because its integrated Extended Scan Interface (ESI) directly digitizes rotary sensor outputs without external analog front-end components. The 128 KB FRAM retains logged consumption and tamper events across decades without flash wear-out, while the AES-128 hardware accelerator secures wireless AMR/AMI transmissions. The 320-segment LCD driver displays cumulative volume, instantaneous flow, and diagnostic icons without an external driver. Active current of 118 uA/MHz plus LPM3.5 standby under 1 uA enable 10-year+ battery life on a single lithium cell, even with hourly logging and daily wireless reports.

Portable Medical and Health Monitors
In portable medical devices such as glucose meters, pulse oximeters, and single-lead ECG patches, the MSP430FR6989IPZ delivers the right mix of analog integration and ultra-low power. The 12-bit SAR ADC with up to 16 channels captures biosensor signals directly, while FRAM stores patient logs and trend buffers with effectively unlimited write endurance - critical for continuous-monitoring patches that log every minute. The integrated LCD driver supports a 320-segment display for readouts, and AES hardware protects patient-identifiable health information during BLE/Miracast synchronization. The device's <1 uA RTC retention standby enables multi-week ambulatory operation from a coin cell.

Industrial Sensor Loggers
Factory-floor vibration, temperature, and pressure loggers benefit from the MSP430FR6989IPZ's FRAM endurance and its mix of analog and serial interfaces. The 12-bit ADC plus 4 timers handle multi-axis vibration sampling, while the 128 KB FRAM circular-buffer architecture logs days of data without fear of flash wear-out. The integrated AES-128 secures factory IP during wireless backhaul via SPI-to-Wi-Fi or SPI-to-LoRa co-processors. The LQFP-100 package with up to 83 GPIO lets designers parallel-wire multiple sensors and displays, replacing PLDs and external logic. LPM3.5 standby below 1 uA extends battery replacement cycles beyond five years in remote installations.

Battery-Powered IoT Edge Nodes
For LoRa-, BLE-, or sub-GHz IoT edge nodes that wake, sense, encrypt, and transmit, the MSP430FR6989IPZ combines sub-1 uA standby, fast FRAM wake-and-execute, and on-chip AES-128 - a near-ideal MCU-side partner for transceivers like the SX126x or CC2640. Its 128 KB FRAM lets designers reserve space for over-the-air firmware images plus rolling sensor buffers, while the integrated LCD driver supports local HMI on a coin-cell device. Compared with Cortex-M0+ IoT MCUs, the MSP430FR6989IPZ delivers competitive MIPS while spending far less energy in sleep, giving months-to-years of battery life in metering and asset-tracking deployments.

LCD Human-Machine Interfaces
The MSP430FR6989IPZ's integrated LCD driver can drive up to 320 segments - enough for a 4-MUX 8-digit numeric display plus icon row - without any external driver IC, simplifying BOM and PCB area. Designers can pair the MCU with segment or dot-matrix LCDs for thermostats, appliances, instrument panels, and consumer electronics. FRAM stores customizable HMI screens and user preferences without flash wear-out even with continuous user updates. The deep-sleep LPM3.5 mode with LCD charge pump disabled allows <2 uA display-off standby, ideal for battery-operated appliances that must wake on button press.
Được đề xuất
Energy-Harvesting Wireless Sensor Nodes
Energy-harvesting applications - solar, thermal, vibrational, or RF - require an MCU that wakes, executes, and returns to deep sleep while consuming the smallest possible energy budget per task. The MSP430FR6989IPZ excels here: its LPM3.5 standby at <1 uA, sub-100 us wake time from FRAM, and 118 uA/MHz active draw let designers extract meaningful work from milliwatt-class harvesters. FRAM's ability to accept partial writes without block-erase simplifies wear-leveling across harvest cycles. The integrated LCD driver adds a local readout for sensor data, and AES-128 secures over-the-air packets when paired with a sub-GHz radio companion.

Ghi chú thiết kế
Estimated: at 16 MHz active current of about 118 uA/MHz, the MSP430FR6989IPZ draws roughly 1.9 mA while executing from FRAM at 3.3 V. In LPM3.5 with RTC retention the device drops below 1 uA, so duty-cycling sensor reads at 1 Hz and FRAM logging at 0.1 Hz typically yields a multi-year battery budget on a single CR2032 coin cell. Always place a 100 nF decoupling capacitor within 2 mm of DVCC1/DVCC2 and a bulk 4.7 uF ceramic near AVCC1 to suppress FRAM-write current spikes.
Estimated: with 83 GPIO plus LCD/ESI/analog functions, route the 100-LQFP layout on a four-layer PCB with a continuous ground plane beneath the device. Keep crystal traces (XIN/XOUT) shorter than 5 mm and shield with a ground ring to avoid coupling into the ESI analog inputs. Reserve a 0.1 uF + 10 uF decoupling pair within 2 mm of each DVCC/AVCC pin pair. For LCD outputs, keep segment traces short and avoid running digital signals parallel to COM lines to preserve contrast.
Three pitfalls recur in MSP430FR6989 designs. First, do not store data in the upper FRAM region reserved for interrupt vectors without remapping - misaligned writes can corrupt vector tables. Second, when migrating from MSP430F5xx flash code, remember FRAM allows byte writes but still requires the SYSCTL unlock pattern before mass erase. Third, the Extended Scan Interface analog inputs share pins with Port 6; users must configure the analog-mux lockout (P6SEL) before invoking ESI calibration routines. Review the SLAU628 user guide before board bring-up.
When driving sub-GHz or BLE radios from the MSP430FR6989IPZ, isolate the radio's noisy supply from DVCC using a ferrite bead and a 10 uF + 0.1 uF LC filter, then keep SMCLK traces short or gate them off when the radio is asleep. The 12-bit SAR ADC achieves 6 ENOB at 200 ksps; sample-and-hold settling time degrades above 50 kohm source impedance, so add an external buffer if the sensor exceeds that threshold.
