Product details
Overview
MSP430BT5190IZQWR 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 supporting UART/IrDA/SPI/I²C, and hardware multiplier. It integrates RTC, DMA, and LDO for battery-powered Bluetooth-enabled devices such as remote controls and smart meters.
For engineers reviewing the MSP430BT5190IZQWR datasheet, MSP430BT5190IZQWR pinout, MSP430BT5190IZQWR application, or MSP430BT5190IZQWR equivalent, key selection criteria include its 87 I/O count, MicroStar Junior BGA-113 package, 1.8–3.6 V supply range, sub-2 µA LPM3 current, and native support for TI CC2560 Bluetooth solutions with Mindtree Ethermind stack.
Technical Context
The MSP430BT5190IZQWR implements a unified clock system with FLL stabilization, dual crystal support (32 kHz XT1 and up to 32 MHz XT2), VLO and REFO internal sources, and programmable core voltage regulation via integrated LDO. Its power architecture enables five low-power modes (LPM0–LPM4.5) with wake-up in under 5 µs from standby.
Peripherals include three independent 16-bit timers with capture/compare capability (TA0: 5 registers; TA1: 3; TB0: 7), four USCI modules (two UART/IrDA/SPI-capable, two SPI/I²C-capable), and a 200 kSPS 12-bit ADC with autoscan, internal reference, and temperature sensor - all optimized for deterministic real-time operation in energy-constrained systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5438AIPZR | Same 113-pin BGA package, 256 KB flash, 16 KB RAM, but lacks Bluetooth-specific peripherals and CC2560 interface optimizations | No native Ethermind stack support; requires external Bluetooth IC and custom driver integration | Select when Bluetooth is not required or when using alternative radio ICs (e.g., nRF52 series) |
| MSP430FR5969IRGCR | Ferroelectric RAM (FRAM) instead of flash; 64 KB FRAM, 2 KB RAM; lower active current (120 µA/MHz), but no integrated LDO or RTC alarm | Superior write endurance and faster nonvolatile storage, but lacks dedicated Bluetooth timing/peripheral co-design | Select for high-data-logging-frequency applications where FRAM write speed outweighs Bluetooth integration needs |
Compared with MSP430F5438AIPZR and MSP430FR5969IRGCR, the MSP430BT5190IZQWR uniquely combines Bluetooth system-level optimization (CC2560 interface, Ethermind stack licensing, SPP profile) with ultra-low-power analog/mixed-signal capabilities - making it the only choice for certified, production-ready Bluetooth cable-replacement designs requiring minimal firmware porting effort.

FAQ
What Bluetooth protocol versions does the MSP430BT5190IZQWR support?
The MSP430BT5190IZQWR supports Bluetooth v2.1 + EDR (Enhanced Data Rate) compliance through its licensed Mindtree Ethermind stack. It implements the Serial Port Profile (SPP) for transparent serial link emulation. The microcontroller itself does not contain a radio; it interfaces externally with TI's CC2560 Bluetooth IC to deliver full protocol stack functionality. MSP430BT5190IZQWR provides dedicated timer, USCI, and GPIO resources optimized for this pairing.
Does the MSP430BT5190IZQWR include an integrated Bluetooth radio?
No, the MSP430BT5190IZQWR is a microcontroller only and does not integrate a Bluetooth radio transceiver. It is designed to operate as the host processor alongside TI's CC2560 Bluetooth IC, handling stack execution, application logic, and peripheral interfacing. The "BT" in the part number denotes Bluetooth system compatibility-not on-die RF functionality. MSP430BT5190IZQWR provides optimized signal routing, clocking, and power sequencing for seamless CC2560 integration.
What is the package type and pin count of the MSP430BT5190IZQWR?
The MSP430BT5190IZQWR uses a MicroStar Junior™ BGA package with 113 balls and 87 functional I/O pins. Its body size is 7 mm × 7 mm with 0.5 mm ball pitch. This compact, high-density package supports fine-pitch PCB assembly while delivering robust thermal performance for battery-powered applications. The pinout is documented in Figure 6-2 and Table 6-2 of the SLAS703C datasheet for MSP430BT5190IZQWR.
Can the MSP430BT5190IZQWR operate from a single 3.0 V coin cell battery?
Yes, the MSP430BT5190IZQWR operates across 1.8 V to 3.6 V, making it fully compatible with standard 3.0 V lithium coin cells (e.g., CR2032). Its integrated LDO regulates core voltage down to 1.8 V, and ultra-low-power modes-including 1.2 µA in LPM4 and 0.1 µA in LPM4.5-enable multi-year operation. MSP430BT5190IZQWR also supports brown-out reset and supply supervision to prevent erratic behavior during battery depletion.
How many analog input channels does the MSP430BT5190IZQWR ADC support?
The MSP430BT5190IZQWR 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 VREF/2). Total usable channels = 16. Channel selection is managed via autoscan mode or manual register writes. The ADC supports up to 200 kSPS sampling rate, internal reference (1.5 V or 2.5 V), and differential input configurations - all confirmed in Section 7.36–7.39 of the MSP430BT5190IZQWR datasheet.
