Product details
Overview
MSP430BT5190IZQWT from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller with 256 KB flash, 16 KB RAM, three 16-bit timers (TA0/TA1/TB0), a 12-bit ADC with 14 external + 2 internal channels, four USCI modules (UART/IrDA/SPI/I²C), and hardware multiplier-designed for Bluetooth-enabled portable medical and metering devices requiring long battery life and integrated wireless serial link capability.
For engineers reviewing the MSP430BT5190IZQWT datasheet, MSP430BT5190IZQWT pinout, MSP430BT5190IZQWT application, or MSP430BT5190IZQWT equivalent, this page delivers verified technical context, exact pin functions for the 113-pin MicroStar Junior BGA package, real-world low-power mode current values, Bluetooth stack integration details, and validated alternative microcontrollers for SPP-based wireless sensor node designs.
Technical Context
The MSP430BT5190IZQWT integrates a unified clock system with FLL stabilization, VLO and REFO internal oscillators, and support for 32-kHz crystals and up to 32-MHz high-frequency crystals-enabling precise timing control across active and low-power modes. Its power-management subsystem includes a programmable LDO core regulator, supply voltage supervisor (SVS), and brownout reset (BOR) circuitry for robust operation from 1.8 V to 3.6 V.
It features eight I/O ports (P1–P11) totaling 87 configurable pins, DMA-driven peripheral operation, RTC with alarm, and dedicated hardware acceleration for UART baud-rate detection and CRC16 computation-optimized for deterministic response in battery-powered Bluetooth peripheral applications interfacing with TI CC2560 transceivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6736IPZ | Same 113-pin BGA footprint; no Bluetooth stack qualification; lacks USCI_B3 and TB0 shadow registers | Targeted at metering-only applications without wireless; requires external Bluetooth module integration | Select when Bluetooth functionality is handled externally and lower cost is prioritized over certified stack integration |
| MSP430FR5969IRGZR | Ferroelectric RAM (64 KB FRAM) instead of flash; 100-pin QFN; lower max clock (16 MHz); no CC2560 co-design validation | Suitable for rapid firmware updates and write-intensive logging; limited to simpler SPP implementations due to fewer USCI instances | Select when field firmware upgrades and energy-efficient nonvolatile storage outweigh certified Bluetooth platform requirements |
Compared with MSP430F6736IPZ and MSP430FR5969IRGZR, the MSP430BT5190IZQWT uniquely provides factory-validated Ethermind stack compatibility, full 87-pin I/O count in compact BGA, and hardware-optimized UART/IrDA for Bluetooth cable replacement-making it the only choice for production-ready, certified SPP peripherals.

FAQ
What Bluetooth protocol versions does the MSP430BT5190IZQWT officially support?
The MSP430BT5190IZQWT is commercially licensed with Mindtree's Ethermind Bluetooth stack and is compliant with Bluetooth v2.1 + EDR. It implements the Serial Port Profile (SPP) for cable replacement applications. No official support for Bluetooth 4.x (BLE), 5.x, or LE Audio is provided-its design focus is classic BR/EDR SPP interoperability with TI CC2560 transceivers.
Does the MSP430BT5190IZQWT include an integrated Bluetooth radio?
No, the MSP430BT5190IZQWT does not contain an integrated Bluetooth radio. It is a standalone microcontroller designed to interface with external TI CC2560 Bluetooth baseband + RF solutions via UART or SPI. The "BT" in its part number denotes Bluetooth system-level qualification-not on-die RF functionality.
What is the maximum operating frequency and corresponding supply voltage range for the MSP430BT5190IZQWT?
The MSP430BT5190IZQWT operates up to 25 MHz with external high-frequency crystal (XT2) and up to 8 MHz using the internal DCO. Its specified supply voltage range is 1.8 V to 3.6 V DC. Operation above 8 MHz requires VCC ≥ 2.2 V per TI SLAS703C Section 7.3 Recommended Operating Conditions.
How many analog input channels does the MSP430BT5190IZQWT ADC support, and are internal references included?
The MSP430BT5190IZQWT features a 12-bit ADC (ADC12_A) with 14 external analog input channels (A0–A15, excluding A10/A11) and 2 internal channels (temperature sensor and VMID). It includes built-in VREF+ and VREF− references, plus support for external reference inputs via P5.0 and P5.1 pins-enabling ratiometric or absolute voltage measurements without external reference ICs.
Is the MSP430BT5190IZQWT pin-compatible with other MSP430x5xx or MSP430x6xx family members?
No, the MSP430BT5190IZQWT is not pin-compatible with standard MSP430x5xx or MSP430x6xx MCUs. While it shares architectural similarities, its 113-pin MicroStar Junior BGA (ZQW) package and signal mapping-including dedicated CC2560 interface pins and unique VCORE power node-are specific to the BT5190 variant. Migration requires PCB redesign and firmware adaptation.
