MSP430F5304IPTR - 16-bit 25MHz 8KB Flash MCU | Texas Instruments

The Texas Instruments MSP430F5304IPTR is a 16-bit ultra-low-power mixed-signal microcontroller based on the MSP430 CPUXV2 RISC core, running at up to 25 MHz with 8KB Flash and 6KB SRAM in a 48-pin LQFP (7x7 mm) package. On-chip peripherals include an integrated 3.3V LDO, four 16-bit timers, a high-performance 10-bit ADC, one USCI supporting UART/SPI/I2C, a hardware multiplier, DMA, an RTC with alarm capabilities, and 31 I/O pins. An ultra-low-power microcontroller (MCU) is a single-chip processor optimized to minimize active and standby current draw, essential for battery-operated and energy-harvesting systems. The MSP430 family sits within the broader hierarchy of 16-bit microcontrollers -> mixed-signal MCUs -> embedded processors, and is widely recognized as an industry benchmark for low-power design. Key features include the flexible clock system with five selectable low-power modes, a hardware 32x32 multiplier that offloads arithmetic from the CPU, and DMA for peripheral-to-memory transfers without CPU intervention. Active-mode consumption is approximately 195 uA/MHz at 8 MHz and 3V during Flash execution, with supply voltage supported from 2.4V to 3.6V. The MSP430F5xx architecture pairs the von Neumann CPUXV2 core with a clock system supporting VLO, REFO, XT1, and DCO sources, allowing designers to trade clock accuracy against current consumption. Interrupt-driven operation with fast wake-up keeps average current in the microamp range in duty-cycled applications. The integrated LDO simplifies the power tree by generating the core supply from a single external rail. Typical applications include battery-powered metering, portable medical monitoring, industrial sensor nodes, and consumer appliances where the combination of 25 MHz performance, one USCI serial port, and 31 GPIO covers most moderate-complexity control tasks. Design consideration: the family shares the MSP430F5xx/F6xx User's Guide peripheral set, so code migrates freely between family members; verify Flash/SRAM sizing and package pinout before board reuse, as memory-density variants exist in identical 48-LQFP footprints.

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.

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.

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.

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. This page synthesizes distributor pricing, drop-in alternative MPNs, and design guidance not consolidated in the manufacturer datasheet, supporting rapid component selection and second-sourcing decisions.

MSP430F6736AIPN - 25MHz Metering SoC MCU 128KB Flash | TI

The Texas Instruments MSP430F6736AIPN is a 16-bit ultra-low-power microcontroller SoC designed for single-phase electricity metering, integrating three independent 24-bit Sigma-Delta ADCs, an LCD driver, real-time clock (RTC), 128KB of Flash, and 8KB of RAM in an 80-pin LQFP (PN) package. It runs the MSP430 CPUXV2 core at up to 25 MHz and operates from 2.5V or 3.3V supplies across -40C to +85C, with rich connectivity including I2C, IrDA, LINbus, SCI, SPI, and UART/USART. A metering SoC (System-on-Chip) is a microcontroller that integrates application-specific analog front-end peripherals - in this case, three precision Sigma-Delta analog-to-digital converters - directly onto the same silicon as the CPU, memory, and display drivers. This topology eliminates the need for an external ADC chip in single-phase energy-meter products, reducing BOM cost and PCB area. The MSP430F6736AIPN sits inside TI's MSP430F6xx metering family, which extends from the broader MSP430 ultra-low-power MCU lineage into the power-measurement domain. Synonyms commonly used in the trade include 'metering MCU', 'energy-meter SoC', and 'e-meter microcontroller'. Key differentiating features of the MSP430F6736AIPN include its 128KB of in-system programmable Flash (sufficient for storing calibration tables, metrology algorithms, and display fonts), an integrated segmented-LCD driver that eliminates external LCD bias-generation hardware, the three 24-bit Sigma-Delta ADCs which simultaneously sample voltage and current channels for class-0.2 or class-0.5 energy accuracy, and ultra-low-power modes that allow the entire meter to draw under 4 mA active while continuously metering. Technically, the device combines a 16-bit RISC MSP430 CPUXV2 core with hardware multiplier, an embedded RTC with calendar, brown-out reset, supply-voltage supervisor, watchdog timer, and multiple timer/capture modules. The three SD24 ADCs achieve effective resolution suitable for IEC 62053-22 class-0.2 meters, and the integrated LCD driver supports up to 320 segments in 8-mux mode. The 80-pin LQFP package exposes all analog and digital pins, with the PN suffix identifying a 12x12 mm body. Typical applications include single-phase residential electricity meters, smart-plug energy monitors, in-home display panels, sub-metering for solar inverters, and industrial power-monitoring controllers. The combination of three SD ADCs and an LCD driver makes the part a true single-chip solution for IEC-compliant class meters. When designing with this device, place the crystal and the SD24 RC components as close to the respective pins as the layout allows, route the analog and digital grounds as separate nets joined at a single point near the IC, and follow TI's 'Single-Phase Metering with the MSP430F6736A' reference design for ADC gain calibration. This page consolidates distributor pricing, drop-in package-matched alternatives, application notes, and design guidance that go beyond a single datasheet table, giving engineers a faster path from datasheet to working single-phase meter prototype.
