A mixed-signal microcontroller combines a digital processor core with peripherals designed to acquire and process analog signals. The MSP430F5438AIZQWR belongs to the MSP430 family of ultra-low-power 16-bit RISC microcontrollers, where CPU processing, communication, timing, and data acquisition are integrated into one device. This makes it suitable for embedded systems that require local sensing, control, and serial communications while keeping component count low. The device provides 256 KB of flash, 16 KB of SRAM, a 25 MHz clock, and a high-performance 12-bit ADC. Its communication peripherals include UART, SPI, and I2C, while DMA supports efficient transfers without repeatedly involving the CPU. The integrated hardware multiplier accelerates suitable arithmetic operations, and three 16-bit timers support periodic events, timing, and control-loop functions. These peripherals make the MCU appropriate for industrial instrumentation, data acquisition, building automation, and low-power embedded control. The MSP430 architecture supports low-power-oriented embedded designs, particularly when the firmware can use its timers, interrupts, and serial interfaces to avoid continuous processor activity. Peripheral integration reduces the need for separate interface or conversion ICs, while DMA can improve responsiveness when moving ADC, communication, or memory data. The 113-ball package provides substantial I/O connectivity, but its fine-pitch BGA construction requires careful PCB layout, inspection, and assembly capability.

MSP430F5507IRGZR

MSP430F5507IRGZR - 25MHz MCU, 32KB Flash, USB 2.0 | Texas Instruments

The Texas Instruments MSP430F5507IRGZR is a 16-bit ultra-low-power mixed-signal microcontroller from the MSP430F5xx family, integrating a 25 MHz MSP430 CPUXV2 core with 32KB Flash, 6KB SRAM (one source quotes 4KB), a 10-bit ADC, DMA, UART/SPI/I2C serial interfaces, hardware multiplier, multiple timers, and a USB 2.0 full-speed peripheral. The device is housed in a 48-pin VQFN (RGZ) package measuring 7x7 mm with an exposed thermal pad. An MSP430 microcontroller is a 16-bit RISC mixed-signal MCU platform from Texas Instruments that occupies the low-power and battery-aware tier of the embedded MCU hierarchy. Within that platform hierarchy the device sits as: MSP430F5xx -> MSP430F55xx (USB sub-family) -> MSP430F550x -> MSP430F5507. The 'F' prefix indicates in-system programmable Flash, the '5' indicates the F5xx generation with the CPUXV2 core and 25 MHz operation, and the trailing digits indicate memory size and feature set. The platform is widely used where deterministic low power and integrated analog matter more than raw MHz. Key differentiating features include active-mode current of 180-195 uA/MHz at 3V, standby current of a few uA, a 1.4 V to 3.6 V wide core supply range (3.6 V absolute max), a true hardware USB 2.0 full-speed transceiver on-chip, a 10-bit successive-approximation ADC with up to 12 external input channels and sample-and-hold, a 32-bit hardware multiplier that accelerates DSP routines, and 31 general-purpose I/O pins. The internal oscillator removes an external crystal in many designs, and the DMA controller offloads data movement between peripherals and memory. At the architectural level, the device uses TI's von-Neumann unified memory map with a 16-bit CPUXV2 core, a 3-stage pipeline, and four hardware multiplier operating modes. The integrated USB peripheral includes an on-chip PHY and pull-up resistors; code can implement HID, CDC, or vendor-class stacks directly. The 10-bit ADC is shared across eight internal and up to twelve external channels through the analog mux, while the DMA engine can stream ADC conversions directly into memory without CPU intervention. Typical applications include USB human-interface devices such as keyboards, mice, and game controllers; portable medical and wellness peripherals; industrial sensor nodes and data loggers; low-power metering; and battery-powered instrumentation that needs an MCU + USB in a single chip. The wide I/O count and integrated analog make it a good fit when an external ADC or signal-conditioning chain would otherwise inflate the BOM. When designing with this part, follow the TI MSP430x5xx Family User's Guide for power-management sequencing, especially the wake-from-LPM transitions and the USB suspend current budget. Reserve the exposed thermal pad for soldering to a ground copper pour to meet the package's thermal-resistance spec and to reduce EMI on the USB DP/DM lines. Use TI's USB Descriptor Tool and MSP430 USB Developers Package firmware to accelerate stack bring-up. This page synthesizes distributor pricing from DigiKey/Mouser/LCSC, verified same-family drop-in alternatives, and practical design notes for USB-aware embedded systems that are not always consolidated in the manufacturer datasheet.

MSP430F5510CY

MSP430F5510CY - 25MHz 16-Bit MCU with 32KB Flash | TI

The Texas Instruments MSP430F5510CY is a 25 MHz, 16-bit mixed-signal microcontroller with 32KB of Flash memory, 4KB of SRAM, a 10-bit ADC, comparator, DMA, UART, SPI, I2C, USB, and a hardware multiplier. The MSP430F5510CY ordering code identifies a die-sale form of the MSP430F5510 family rather than a leaded or surface-mount package. A mixed-signal microcontroller is an integrated circuit that combines a programmable digital controller with analog measurement or comparison functions. In the product hierarchy, the MSP430F5510 belongs to the MSP430 mixed-signal microcontroller family, which is a type of 16-bit embedded processor and system-on-chip. Its combination of low-power-oriented control, serial interfaces, USB connectivity, and analog peripherals allows sensing and control tasks to be consolidated in compact embedded systems. The principal verified specifications are a 25 MHz maximum clock, 32KB Flash organized as 32K x 8, 4KB SRAM, and a 10-bit ADC. The device also provides a comparator, DMA controller, UART, SPI, I2C, USB interface, and hardware multiplier. These resources support applications that require periodic analog sampling, event-driven data transfer, low-rate communication, or multiplication-intensive control without requiring a separate analog front end for every function. The MSP430F5510 uses the MSP430 CPUXV2 architecture and belongs to the MSP430F5xx mixed-signal family. DMA can move data independently of the CPU, while the hardware multiplier accelerates multiplication tasks. The parallel availability of UART, SPI, and I2C permits a designer to connect sensors, displays, storage devices, and other embedded modules while retaining USB for a host-oriented interface. Exact ADC timing, USB details, clock configuration, and electrical limits should be confirmed in the manufacturer datasheet before final design release. Typical uses include industrial sensor nodes, compact USB-connected data collectors, building and equipment controls, low-power monitoring equipment, and mixed-signal instruments. In an analog-monitoring design, the 10-bit ADC can acquire sensor signals while the comparator handles threshold events and DMA transfers results into SRAM. UART, SPI, or I2C can then connect the controller to local peripherals, while USB provides a higher-level connection when required. The most important design consideration for the MSP430F5510CY is that CY is a die-sale device rather than a finished, pin-defined package. Its footprint, assembly process, bonding method, die orientation, and exposed features therefore require direct coordination with the assembly provider. Engineers must also verify clock, memory, USB, analog, and power requirements against the MSP430F5510 datasheet and validate the assembled board before production. This page consolidates the verified manufacturer specifications, current distributor pricing reference, die-sale packaging information, application guidance, and the documented absence of a confirmed drop-in replacement. It also distinguishes verified facts from package-specific information that cannot be inferred from the bare-die ordering code.

The Texas Instruments MSP430F6638CY is a 20 MHz, 16-bit mixed-signal microcontroller with 256KB of Flash memory, 16KB of SRAM, a 12-bit ADC, a 12-bit DAC, a comparator, DMA, USB connectivity, and support for a 160-segment LCD. The device is identified as a die-sale product, so the MSP430F6638CY ordering code is not associated with a standard finished package in the manufacturer product information shown here. A mixed-signal microcontroller combines a digital processor with analog conversion and other peripheral functions on one integrated circuit. The MSP430F6638 belongs to the MSP430F6xx family, whose 16-bit RISC CPUXV2 architecture uses a reduced instruction set designed for efficient embedded control. USB, serial interfaces, DMA, and high-resolution analog peripherals make this device suitable for industrial instrumentation, data acquisition, communications, and control systems where integration can reduce external component count. The MSP430F6638 operates with a 20 MHz maximum clock and provides 256KB of program Flash plus 16KB of SRAM. Its analog resources include a 12-bit ADC and 12-bit DAC, while the integrated comparator supports thresholding and signal monitoring. Additional peripherals include DMA, brown-out detection and reset, power-on reset, PWM, a watchdog timer, and a 160-segment LCD driver. These features support real-time acquisition, local control loops, human-machine interfaces, and firmware-managed peripheral movement. The device provides I2C, IrDA, LINbus, SCI, SPI, UART/USART, and USB connectivity. USB can support a direct host or device-oriented peripheral role, while the serial interfaces allow connection to sensors, transceivers, displays, and external converters. The 74 I/O positions indicated for the MSP430F6638 family provide a broad hardware interface for a platform assembled from bare die or a qualified module. Because MSP430F6638CY is offered as die sale rather than a conventional packaged ordering option, assembly into a finished electronic assembly requires die attach, wire bonding, electrical verification, and a package or substrate designed for the device. The die-sale designation also means that exposed-pad, lead, pinout, and standard package drawings cannot be assigned safely without the bonding map or assembly documentation. For new production designs, engineers should use the MSP430F6638 family documentation, confirm the available memory and peripheral configuration, and plan the analog input conditioning around the ADC resolution. USB signal routing requires controlled impedance and careful placement of protection and bypass components, while firmware should verify reset behavior and watchdog behavior during startup. This product summary consolidates the manufacturer specifications, ordering information, interface capabilities, die-sale constraints, and application guidance needed to evaluate the MSP430F6638CY before beginning an embedded mixed-signal design.

MSP430F6723IPZ - 25 MHz Metering MCU | Texas Instruments

The Texas Instruments MSP430F6723IPZ is a 16-bit ultra-low-power mixed-signal microcontroller designed for single-phase metering, with a 25 MHz maximum CPU speed, 64 KB of Flash memory, 4 KB of RAM, and two sigma-delta ADCs. It is housed in a 100-pin LQFP (PZ) package rated for -40 °C to 85 °C. A mixed-signal microcontroller combines a digital processor with analog front-end and energy-measurement peripherals on one device. The MSP430F6xx family belongs to the broader embedded MCU category and provides programmable real-time control for energy meters, utility data concentrators, industrial monitoring systems, and portable measurement equipment. Its integration reduces component count while keeping sensing, computation, display control, and communication functions within one low-power device. Key features include 72 configurable I/O pins, two 16-bit sigma-delta ADCs, LCD drive capability, and an internal real-time clock. The device operates from a 3.6 V low-supply range and is specified at 265 µA/MHz in active mode with all system clocks operating at 8 MHz and 3.0 V. These characteristics support metering designs that must continuously acquire analog energy signals while controlling a segment or matrix LCD. The MSP430 architecture uses a 16-bit RISC core with 16-bit registers and constant generators, supporting efficient metering algorithms and compact firmware. Multiple low-power operating modes help reduce energy consumption when the meter is idle, while the real-time clock allows time-of-use measurement and load-profile timing without an external clock component. Typical applications include single-phase electricity meters, smart grid endpoint equipment, industrial energy monitors, and low-cost data loggers with LCD displays. The two sigma-delta channels are particularly relevant to current and voltage sensing, where oversampled conversion and digital filtering improve signal resolution before calculations are performed by the CPU. When laying out a meter board, reserve isolated analog routing for the sigma-delta inputs and keep LCD segment, crystal, and high-current drive connections away from the measurement front end. Confirm the complete pin-assignment table in the manufacturer datasheet before routing, especially for the exposed ground and supply pins in the 100-pin LQFP footprint. This page organizes the device specifications, verified alternatives, metering application guidance, and PCB-level design considerations to support faster component selection and board bring-up.

MSP430F6734AIPNR

MSP430F6734AIPNR - 16-bit 96KB Flash Metering SoC | Texas Instruments

The Texas Instruments MSP430F6734AIPNR is a single-phase metering system-on-chip (SoC) built around the 16-bit MSP430 CPUXV2 core running at up to 25 MHz, integrating 96 KB Flash and 4 KB RAM in an 80-pin LQFP (PN) package measuring 12 x 12 mm. It is purpose-engineered for metrology and energy-meter front-ends, combining three independent 24-bit sigma-delta analog-to-digital converters, an on-chip real-time clock, hardware LCD driver, and the ultra-low-power MSP430 architecture to deliver years of battery life on a single lithium cell. Background: A metering SoC is a class of mixed-signal microcontroller optimized for accurate measurement of line-voltage and line-current waveforms in single- or poly-phase electricity meters. Within the broader power-management IC hierarchy, the metering SoC sits alongside analog front-ends (AFEs), metrology coprocessors, and standard MCUs, but uniquely combines the metering-specific sigma-delta data path, reference, and LCD segment drive into a single low-power die. This integration eliminates the need for a dedicated metrology AFE companion chip and reduces BOM count. Key differentiating features include the three 24-bit sigma-delta ADCs with built-in programmable gain amplifiers, dedicated tamper-detection input pins for anti-tamper designs, hardware RTC with calendar function, integrated segmented LCD driver supporting up to 320 segments, and the MSP430 CPUXV2 core offering multiple low-power modes (LPM3, LPM4) with sub-microamp standby current. The 96 KB Flash supports full application firmware plus IEC 62053-22 calibration tables. Technical depth: The three sigma-delta ADCs are paired with on-chip voltage reference and gain stages, enabling simultaneous sampling of phase voltage, phase current, and neutral current with effective number of bits (ENOB) suitable for Class 0.2 or Class 0.5 meters per IEC 62053. The 25 MHz CPUXV2 core provides ample headroom for FFT-based harmonic analysis up to the 63rd harmonic while remaining in active mode only during measurement windows. Typical applications include single-phase residential electricity meters, smart energy monitoring sockets, energy-harvesting IoT sensors, prepayment meters, and battery-backed tamper-detecting metering nodes. The integrated LCD driver eliminates a separate driver chip and reduces cost in display-equipped designs. Compared with a discrete MCU + AFE solution, the SoC approach reduces PCB area by approximately 40% and BOM cost. Design consideration: When laying out the PCB, keep the analog sigma-delta traces short and symmetric to avoid degrading effective resolution, place the 32.768 kHz crystal within 5 mm of the XIN/XOUT pins, and provide a solid ground plane under the device to minimize noise coupling into the metrology inputs.

Communication interfaces include up to four USCI modules supporting UART/SPI/I2C, IrDA encoder/decoder, and JTAG/SBW for in-system programming and debugging. The MSP430F6736AIPNR uses TI's MSP430 CPUXV2 16-bit RISC core with a 16-bit register file, hardware multiplier, and four-byte fetch. Code execution from Flash at 25 MHz delivers 1.46 DMIPS/MHz (Whetstone equivalent). The architecture trades absolute throughput for energy efficiency: each peripheral can be individually clock-gated, and the CPU enters one of five low-power modes (LPM0-LPM4) with standby currents below 1 uA. Typical applications include single-phase electricity meters (Class 0.2/0.5/1.0 accuracy), smart energy monitoring plugs, solar PV string monitors, appliance line-monitoring controllers, and any battery-aware IoT sensor requiring an integrated LCD. Pin compatibility with the F6736A family allows easy migration to higher-memory or lower-cost variants. When designing with this device, place the three sigma-delta ADC inputs in a quiet ground island and route the analog LDO output to dedicated AVDD pins. The device ships in tape and reel (T&R) and is lead-free / RoHS compliant.

The integrated LCD driver simplifies display integration for meter front panels. Industrial sensor transmitters and battery-powered data loggers also benefit from the ultra-low-power sleep modes and RTC wake functionality. Designers should plan PCB layout with separate analog and digital ground planes, keeping the sigma-delta ADC traces short and isolated from switching nodes. Use low-ESR ceramic bypass capacitors within 5mm of each supply pin. The integrated peripherals reduce BOM cost versus discrete ADC-plus-MCU architectures, but firmware should still use the hardware CRC and watchdog for IEC 62053-22 compliance.

The integrated analog blocks remove the need for external signal-conditioning ICs in many sensor-interface designs. Architecturally, the device leverages TI's MSP430 CPU16 core with a 3-stage pipeline and 16-bit RISC instruction set. FRAM delivers 100× lower write energy than Flash, supports byte-level writes at full CPU speed (no erase cycles), and offers 100× higher endurance (≥ 10^14 cycles) compared to conventional Flash. The integrated smart analog combo (SAC) lets each op-amp operate in general-purpose, PGA, transimpedance, or unity-gain-buffer mode without external resistors, reducing BOM and PCB area. Typical applications include battery-powered IoT sensor nodes, analog signal conditioning for temperature/RTD/photodiode front ends, portable medical and fitness monitors, smart-meter data acquisition, and industrial 4–20 mA loop transmitters. The combination of high-integrity FRAM storage and on-chip analog is especially attractive for data loggers that must retain calibration history across power cycles. When designing, note that the LQFP-48 (PT) package shares pinout with other MSP430FR2xx family members, allowing upward migration (e.g., to MSP430FR2355 with more memory) and downward scaling without PCB redesign. Provide a clean analog supply (AVCC) decoupling network with 1 µF + 100 nF ceramic capacitors close to pins, and follow TI SLAA704 layout guidance for SAC routing.

The integrated 10-bit ADC and 1.5 KB of additional FRAM over the sibling MSP430FR2422 family gives designers headroom for data logging without external EEPROM. The architecture centers on a 16-bit RISC MSP430 CPU16 core with 16 registers, hardware multiplier, and a unified memory map that lets FRAM be partitioned arbitrarily between code and data. The chip also features a wide 1.8 V-3.6 V supply range, brownout reset, and a low-power boron-doped polysilicon process. Performance analysis shows the device achieves 16 MIPS at 16 MHz while consuming ~700 µA/MHz active and ~0.5 µA in LPM3.5 retention. Typical applications include battery-powered IoT sensor nodes, water/gas metering, electronic shelf labels, HVAC thermostats, wearable health monitors, and any portable sensing application requiring 10-bit analog measurement and years of battery life. Its tiny 16-TSSOP footprint makes it suitable for space-constrained PCB designs. When designing with the MSP430FR2422IPW16, ensure decoupling is placed close to DVCC/AVCC pins (1 µF + 100 nF) and that unused ADC channels are tied to ground to minimize leakage. For long-term retention in LPM4.5, hold RESET low to enter ship mode and reduce quiescent current to <100 nA.

FRAM provides non-volatile storage with high write endurance and fast write speeds, making it suitable for data logging and battery-powered sensing. The CPU16 core uses a von-Neumann architecture with a unified memory space, a hardware multiplier, and low-power modes LPM0-LPM4. These modes allow the device to wake quickly from deep sleep while consuming minimal current, which is critical for portable and energy-harvesting designs. The integrated 10-bit ADC with internal reference simplifies direct connection of analog sensors without external converter ICs. Typical applications include industrial sensors, medical and health monitoring devices, smart meters, portable instrumentation, and IoT sensor nodes. The combination of low power, non-volatile FRAM, and the compact VQFN-24 package makes the MSP430FR2433IRGER especially suited for space-constrained designs that must retain data during power loss. When designing with this MCU, tie the exposed thermal pad on the bottom of the VQFN package to the PCB ground plane for optimal thermal and electrical performance. Place 100 nF and 10 µF decoupling capacitors close to the supply pins. For lowest power consumption, use the low-power modes and disable unused peripherals in firmware.

MSP430FR2476TPT - 16MHz MCU 64KB FRAM 48-LQFP | Texas Instruments

The Texas Instruments MSP430FR2476TPT is a 16-bit RISC mixed-signal microcontroller in the MSP430FRxx value-line portfolio, integrating 64KB of FRAM, 8KB of SRAM, and a 12-bit ADC in a 48-pin LQFP (TPT) package. The CPU16 core runs up to 16 MHz and is paired with ultra-low-power peripherals for sensing and measurement applications. Wide supply voltage range from 3.6V down to 1.8V (minimum supply voltage is restricted by SVS levels) supports battery and energy-harvesting designs. What is an MSP430 FRAM MCU? An MSP430 FRAM microcontroller is a 16-bit ultra-low-power MCU that uses Ferroelectric Random Access Memory (FRAM) instead of flash for non-volatile code and data storage. FRAM combines the speed of SRAM with the non-volatility of flash, enabling faster writes (100x faster than flash), higher endurance (10^15 write cycles vs 10^5 for flash), and unified memory for code/data, which simplifies firmware design and enables in-field data logging at high rates. FRAM MCUs sit in the broader taxonomy: microcontroller -> embedded MCU -> 16-bit MCU -> ultra-low-power MCU -> MSP430 family -> FRAM value line. Key features of the MSP430FR2476TPT include: 16 MHz CPU16 core, 64.5KB (64K x 8) FRAM program/data memory, 8KB SRAM, an integrated 12-bit SAR ADC with multiple channels, an analog comparator, hardware UART/SPI/I2C, multiple 16-bit timers, and an intelligent digital peripherals interface. The device ships in a 48-pin LQFP (7x7 mm) package suitable for low-cost PCB designs. The architecture centers on a 16-bit RISC core optimized for low active current and ultra-low standby current, enabling years of operation on a single coin cell. FRAM enables byte-addressable non-volatile storage with near-instant write times, allowing data logging and wireless firmware updates without the erase-then-write cycle penalty of flash. The 12-bit ADC supports internal voltage reference and temperature sensor channels for direct sensor interfacing. Typical applications for the MSP430FR2476TPT include battery-powered sensor nodes, IoT end nodes, low-cost data loggers, energy-harvesting devices, smoke/CO detectors, smart thermostats, fitness wearables, and home automation peripherals. The combination of low cost, ultra-low power, and integrated analog peripherals makes it well suited for always-on sensing applications where energy budget is measured in microwatts. When designing with the MSP430FR2476TPT, follow the MSP430 hardware user's guide for SVS threshold settings, decoupling capacitor placement, and JTAG/SBW programming connections. Use the MSP-TS430PZ48 target board for development and the free MSP430Ware/Code Composer Studio toolchain for code development. Pay attention to the SVS minimum supply voltage restriction to avoid brown-out at low VCC.

The MSP430FR2476TPT is a member of the wider MSP430FR247x family and shares the same 48-LQFP (TPT) footprint across the TPT and TPTR tape-and-reel variants.

MSP430FR5989IPMR - 128KB FRAM 16MHz Rotary Sensing MCU | TI

The Texas Instruments MSP430FR5989IPMR is a 16-bit ultra-low-power microcontroller based on the MSP430 CPUXV2 RISC core running at up to 16MHz, with 128KB embedded FRAM, 2KB SRAM, and an extended Scan Interface 2 for rotary sensing, housed in a 64-pin LQFP (PM) 10x10mm package. A microcontroller (MCU) is a compact integrated circuit that combines a processor core, program memory, data memory, and programmable peripherals on a single die to govern a specific embedded function. Within the MCU hierarchy, this device belongs to the MSP430 FRAM family of ultra-low-power (ULP) microcontrollers under the broader MSP430 platform and power-management IC taxonomy. Its FRAM (ferroelectric RAM) memory unites SRAM-like speed, flexibility, and endurance with flash-like non-volatility at much lower write energy, eliminating the erase-before-write cycles of conventional flash. Key features include the extended Scan Interface 2 that offloads high-resolution rotary and linear position sensing from the CPU, a hardware AES accelerator for secure metering data, a real-time clock with calendar mode, a 12-bit ADC, comparator, DMA controller, a 32-bit hardware multiplier, and multiple 16-bit timers. Power performance is exceptional: active mode draws approximately 100 uA/MHz and standby (LPM3 with VLO) about 0.4 uA, enabling decade-class battery life in field instruments. Architecturally, the CPUXV2 core executes a 16-bit RISC instruction set over a von Neumann bus at 16MHz. FRAM is byte-writable in-system, allowing fast data logging without external EEPROM, while the AES accelerator encrypts measurements for smart-grid and flow-metering security. The operating supply range is 1.8V to 3.6V with -40C to +85C temperature tolerance for harsh deployments. Typical applications include gas, water, and heat flow meters, rotary and linear position sensing systems, smart-grid endpoints, industrial process control, and secure wireless sensor nodes. Scan Interface 2 directly supports rotary encoders while the CPU sleeps, minimizing average current. Design tip: decouple each VCC pin with 100nF close to the pin plus 10uF bulk capacitance, keep the supply above the SVS threshold for reliable FRAM writes, and use JTAG or two-wire Spy-Bi-Wire for debugging.
