MSP430F6736AIPNR - 128KB Flash 16-Bit Metering SoC | TI

The Texas Instruments MSP430F6736AIPNR is a 16-bit RISC ultra-low-power single-phase metering system-on-chip (SoC) with three independent 24-bit sigma-delta ADCs, an integrated LCD driver, real-time clock, 128 KB Flash and 8 KB RAM, packaged in an 80-pin LQFP (PN) at 12x12 mm. The CPU core runs at up to 25 MHz and the device supports 1.8V-3.6V supply with active-mode current typically in the 200-400 uA/MHz range, suitable for line-powered and battery-aware smart-meter designs. A single-phase metering SoC is a microcontroller with on-chip analog front-end and LCD driver, purpose-built to perform metrology calculations (RMS voltage, RMS current, active/reactive power, energy) for one residential or commercial phase. The MSP430 family belongs to the broader hierarchy: metering MCU -> mixed-signal microcontroller -> 16-bit microcontroller -> ultra-low-power MCU -> embedded processor. Sigma-delta ADCs offer 24-bit resolution at low sample rates, ideal for current transformers and shunt-based sensing where high dynamic range and noise rejection matter more than bandwidth. Key features include three 24-bit sigma-delta ADCs with differential inputs and programmable gain, hardware AES-256 accelerator on most F67xxA derivatives, integrated LCD driver supporting up to 320 segments, on-chip RTC with calendar, brown-out reset, supply voltage supervisor, and a multi-channel 10-bit SAR ADC on shared pins. 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 CPU runs at up to 25 MHz from the MSP430 CPUXV2 core, and the device operates from 1.8V to 3.6V across an industrial -40C to +85C temperature range. According to the manufacturer datasheet, three sigma-delta ADCs were pre-tuned for voltage and current sensing channels typical of class-0.2 metering accuracy. An MSP430 microcontroller is a 16-bit RISC mixed-signal processor from Texas Instruments designed for ultra-low-power embedded applications. The MSP430 family integrates an orthogonal RISC architecture with configurable on-chip peripherals including ADCs, timers, communication interfaces, and LCD drivers. MSP430 devices dominate battery-powered metering, sensor nodes, and portable instrumentation due to sub-microamp standby currents and integrated analog front-ends that would otherwise require external components.

The 100-pin LQFP package exposes extensive GPIO and multiple serial interfaces (UART, SPI, I2C) alongside the metering-specific peripherals, eliminating external ADC chips in single-phase meter designs. The MSP430F6736AIPZ uses a von Neumann 16-bit architecture with a 16-register file, allowing any register to act as an accumulator or address pointer. Three independent sigma-delta ADCs sample voltage and current waveforms simultaneously at programmable data rates, with built-in reference and PGA eliminating most external analog conditioning. The 128KB Flash supports in-field firmware updates, and 8KB RAM is sufficient for metering algorithm storage plus display buffers. Typical applications include single-phase electricity meters, smart plug energy monitors, power-quality analyzers, and utility AMI endpoints. 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 FRAM write mechanism requires no erase cycle, so data logging writes are roughly 100x faster and far lower energy than flash-based writes. Typical applications include battery-powered metering and data logging, portable medical monitoring, sensor-fusion nodes performing DSP pre-processing via LEA, and secure connected endpoints using the AES256 engine. Designers should note that FRAM read timing is fast but the maximum system frequency of 16 MHz requires wait-state management for FRAM access above 8 MHz, and the LQFP-64 PM package needs a solid DVSS/DVCC decoupling network per TI's layout guidance.

Texas Instruments MSP430G2553CY is a 16-bit mixed-signal microcontroller operating at 16 MHz, with 16 KB of Flash memory and 512 bytes of SRAM. The device combines a comparator, timers, UART, SPI, and I2C interfaces in a 32-pin QFN package. The supplied ordering information identifies this orderable MPN as a die-sale device, so package-specific mechanical details and production procurement terms must be confirmed with TI before assembly. A mixed-signal microcontroller is an embedded semiconductor that combines a programmable digital controller with analog or sensing functions. In the product hierarchy, this MSP430 belongs to the microcontroller, embedded processor, semiconductor, and mixed-signal controller classes. Its 16-bit MSP430 CPU architecture makes it suitable for compact control systems requiring low power, deterministic peripheral access, and several communication interfaces without a separate analog processor. The verified device information identifies a 16 MHz operating speed, 16 KB Flash, 512 B SRAM, one comparator, UART/SPI/I2C connectivity, and timers. DigChip additionally lists 24 I/O ports, a 3.3 V to 3.6 V supply range, and a 0.1 µA off-mode current with RAM retention. These figures position MSP430G2553CY for low-power sensing, control, instrumentation, and communications designs where memory and integrated interfaces are more important than high-speed digital processing. The MSP430G2xx family architecture is oriented toward low-power embedded control. Its integrated comparator supports threshold-based sensing, while UART, SPI, and I2C support connections to sensors, displays, transceivers, and external nonvolatile memory. The timer resources can provide event timing and periodic service functions, but individual timer channels, capture/compare resources, and interrupt assignments must be selected from the MSP430G2x53 datasheet for the exact die. Typical applications include battery-powered sensor nodes, compact industrial monitors, digital thermometers, environmental measurement systems, motor or actuator controllers, and simple serial gateways. For a new PCB, the CY suffix and die-sale status require careful review: developers should not assume that the QFN-32 package information found in generic listings corresponds to the CY deliverable. Board assembly may instead require the documented die-sale process, bonding method, and package outline. Before layout, confirm the exact pin assignment and exposed-pad requirements in the official MSP430G2x53 datasheet and with TI. Program development commonly uses an MSP430-compatible toolchain, but the verified data does not identify a specific IDE version, debugger, or programming adapter. Power, ground, decoupling, reset, boot-strapping, communication, and exposed-pad connections should therefore follow the authoritative device documentation rather than generic QFN assumptions. This page consolidates verified manufacturer and distributor information, separates die-sale ordering facts from generic family specifications, and identifies unresolved package, pricing, pinout, lifecycle, and compliance details instead of guessing. It is intended as an engineering-data starting point for MSP430G2553CY sourcing and design review, not as a substitute for TI's final orderable datasheet and quality documentation.

The MSP430G2553 belongs to the MSP430 family of ultra-low-power microcontrollers and targets applications that require deterministic control, efficient peripheral integration, and low standby consumption. Its architecture supports portable instruments, sensing nodes, data acquisition modules, and small embedded-control systems. Key features include a 16-bit RISC CPU operating at up to 16 MHz, 16 KB of Flash, 512 bytes of SRAM, a 10-bit ADC, an analog comparator, UART, SPI, I²C, and timers. The integrated peripherals reduce external component count and allow compact designs that measure analog inputs while exchanging data with external sensors, displays, or host systems. The manufacturer identifies the device for low-power portable measurement applications. The MSP430 architecture uses 16-bit registers and an interrupt-oriented peripheral model. Its mixed-signal resources support sensor conditioning and threshold comparison without requiring a separate analog processor, while UART, SPI, and I²C interfaces provide paths to external integrated circuits. The 20-pin PDIP package also exposes the device through a conventional through-hole footprint suitable for prototyping, education, and industrial control boards. Typical uses include battery-powered measurement instruments, simple data loggers, environmental sensors, industrial sensing nodes, keypad interfaces, and compact embedded-control products. UART, SPI, or I²C can connect a sensor module or local display, while the ADC and comparator support analog measurement. The MSP430G2553IN20 is also widely used as the target device for MSP430 LaunchPad-style development and educational projects. Designers should verify the exact pin functions and peripheral multiplexing against the manufacturer datasheet before laying out the PCB. Decoupling, grounding, unused-pin handling, clock configuration, and low-power mode sequencing are critical in a compact mixed-signal design. The verified data does not provide a complete pin-level mapping, so pin names and electrical details not explicitly supplied are marked as needed rather than inferred.

MSP430G2553IPW0RQ1 - 16MHz Automotive MCU | Texas Instruments

The Texas Instruments MSP430G2553IPW0RQ1 is an automotive 16-bit mixed-signal microcontroller operating at 16 MHz, with 16 KB of Flash memory, 512 B of SRAM, and a 10-bit ADC. It is supplied in a 20-pin TSSOP (PW) package rated for -40°C to +85°C and integrates UART, SPI, I²C, timer, and comparator peripherals. A mixed-signal microcontroller is a semiconductor device that combines a programmable digital controller with analog measurement or signal-conditioning resources. The MSP430 belongs to the MCU → microcontroller → embedded processor → semiconductor hierarchy and is designed for compact, low-power control systems. Its 16-bit CPU16 architecture, on-chip memory, and communication peripherals allow standalone sensing and control without requiring separate memory, ADC, or serial-interface devices. Key device resources include a 16 MHz maximum clock, 16 KB of Flash program memory, 512 B of SRAM, a 10-bit analog-to-digital converter, and an integrated comparator. The MCU supports UART, SPI, and I²C communication, while timer resources support periodic measurement, timing, and control functions. The -40°C to +85°C operating range and automotive qualification make the Q1 device suitable for demanding vehicle electronic modules. The MSP430G2 family architecture combines compact digital processing with mixed-signal measurement. Flash memory retains programmed firmware across power removal, while SRAM supports working variables and stack operations. The ADC provides an integrated path for analog inputs, and the comparator can support threshold detection or basic signal monitoring. Serial interfaces allow the device to communicate with sensors, transceivers, memories, and external controllers. Typical uses include automotive body and sensing modules, battery-powered instrumentation, condition-monitoring controllers, compact data loggers, and low-power industrial controls. The device is especially appropriate where a small TSSOP footprint, mixed-signal integration, and multiple serial interfaces are more valuable than a high-pin-count application processor. Designers should preserve the power, ground, and decoupling layout recommended by the MSP430G2553-Q1 datasheet and verify unused I/O states in the final design. Because automotive qualification, operating-temperature grade, and ordering suffix affect procurement, replacements should be checked for identical package pinout, 16 MHz operation, memory capacity, ADC resolution, and peripheral configuration before substitution. This product page consolidates the verified manufacturer and distributor information for MSP430G2553IPW0RQ1, including package and memory details, current purchasing data, drop-in replacement guidance, comparison parameters, and practical design considerations.
