MSP430F5519IPNR 16-bit Microcontroller TSSOP-38

MSP430F5519IPNR Overview

The MSP430F5519IPNR is a low-power, 16-bit microcontroller designed for USB-capable embedded designs that demand efficient processing and robust peripheral integration. It combines a 16-bit RISC core running up to 25 MHz with on-chip USB 2.0 full-speed support, a 12-bit analog converter, and non-volatile storage. With 128 KB of Flash and 8 KB of RAM, it offers more code and data space than many 8-bit controllers, while maintaining sub-milliamp sleep currents for battery-conscious systems. See official resources from IC Manufacturer for ordering and lifecycle details.

MSP430F5519IPNR Technical Specifications

MSP430F5519IPNR Key Features

• Single 16-bit RISC core at up to 25 MHz ?? provides deterministic performance with lower code size than many 32-bit alternatives.
• On-chip USB 2.0 full-speed peripheral (12 Mbps) ?? simplifies USB connectivity without external transceivers or controllers.
• 128 KB Flash and 8 KB RAM ?? supports more complex firmware and larger buffers compared with typical 8-bit MCU options.
• 12-bit ADC ?? gives higher measurement resolution for sensors and control loops than 8-bit converters.
• Multiple on-chip 16-bit timers and peripheral modules ?? reduce external components and improve integration for motor control, timing, and PWM tasks.
• Wide 1.8?C3.6 V supply range ?? enables direct operation from common battery cells and 3.3 V rails.
• Industrial temperature rating (-40 ??C to +85 ??C) ?? suitable for harsh and factory-floor conditions.
• Small TSSOP-38 package ?? balances board area and pin access for mixed-signal designs.

Typical Applications

• Battery-powered USB sensor nodes that require low standby current and reliable full-speed USB connectivity for data upload or firmware update.
• Industrial control interfaces where the 16-bit core, 12-bit ADC, and multiple timers provide stable closed-loop control and accurate analog measurement over wide temperature ranges.
• Consumer peripherals that need USB device support and more program space than 8-bit MCUs, enabling richer GUIs, logging, or protocol stacks.
• Data acquisition modules that combine on-chip USB, 12-bit analog conversion, and modest SRAM to stream sensor data at higher resolution to host systems.

MSP430F5519IPNR Advantages vs Typical Alternatives

The device mixes low-power operation with mid-range compute and integrated USB, giving a better balance than many 8-bit controllers for USB-connected products. With 128 KB of Flash and a 16-bit architecture, it often requires fewer external components and less code optimization than constrained MCUs. Its 1.8?C3.6 V range and industrial temperature rating let it fit into wider application sets than narrow-voltage parts. The on-chip USB and higher-resolution ADC reduce system cost and complexity compared with controllers that need external peripherals.

FAQ

What package does it use?

The device is supplied in a TSSOP-38 package (IPNR designation). This package offers a compact footprint with exposed pins for mixed-signal board layouts and soldering compatibility with typical TSSOP-38 footprint designs.

What is the operating voltage range?

This microcontroller runs from 1.8 V to 3.6 V. That range supports single-cell lithium batteries, common 3.3 V rails, and systems that need low-voltage operation without external regulators in some cases.

Does it include USB support?

Yes. The device includes on-chip USB 2.0 full-speed functionality (12 Mbps). This removes the need for a separate USB controller and simplifies firmware stacks for USB device communication and firmware upgrade use cases.

How much non-volatile memory is available?

It provides 128 KB of on-chip Flash for program storage. This amount accommodates larger application code, USB stacks, or file-system style arrangements compared with many smaller MCUs.

Is it suitable for industrial environments?

Yes. The specified operating range down to -40 ??C and up to +85 ??C and the device’s integrated features make it suitable for many industrial and rugged embedded applications.
