Product details
Overview
MSP430BT5190IZCAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller designed for Bluetooth-enabled portable measurement systems. It integrates 256 KB Flash, 16 KB RAM, a 12-bit ADC with 14 external + 2 internal channels, three 16-bit timers (TA0/TA1/TB0), four USCI modules supporting UART/IrDA/SPI/I²C, and a real-time clock with crystal support - all operating from 1.8 V to 3.6 V supply.
For engineers reviewing the MSP430BT5190IZCAR datasheet, MSP430BT5190IZCAR pinout, MSP430BT5190IZCAR application, or MSP430BT5190IZCAR equivalent, this device is selected for battery-powered wireless sensor nodes requiring sub-2 µA LPM3 RTC retention, <5 µs wake-up, and integrated Bluetooth host controller interface compatibility with CC2560 solutions.
Technical Context
The MSP430BT5190IZCAR implements TI's Unified Clock System with DCO-based FLL for frequency stabilization, dual crystal oscillators (XT1 for 32 kHz RTC, XT2 up to 32 MHz), and programmable LDO core regulation (VCORE). Its architecture supports simultaneous low-power operation and high-precision analog acquisition via autoscan-capable ADC12_A running at 200 kSPS.
It features three-channel DMA, hardware multiplier for 32-bit operations, and eight 8-bit I/O ports (P1–P11) delivering 87 total GPIOs with interrupt capability on most pins. The device is explicitly configured for coexistence with TI's CC2560 Bluetooth baseband IC and Mindtree Ethermind stack to implement SPP-based cable replacement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal Bluetooth host controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5438AIPZR | No integrated Bluetooth stack support; lacks CC2560-specific peripheral mapping and Ethermind-certified firmware layer. | Suitable for custom wireless protocols or non-Bluetooth sensor hubs; requires full stack development effort. | Select when Bluetooth functionality is implemented externally or not required - offers larger 256 KB RAM but no BT-optimized USCI configuration. |
| MSP430FR5969IPM | Ferroelectric RAM (FRAM) instead of Flash; lower active current (120 µA/MHz); no native CC2560 interface guidance in documentation. | Better for ultra-low-energy logging or frequent write-cycle applications; lacks production-validated BT+CC2560 reference designs. | Select for energy harvesting or high-write-cycle applications where Bluetooth integration is handled via software abstraction rather than hardware co-design. |

FAQ
What is the primary target application for the MSP430BT5190IZCAR?
The MSP430BT5190IZCAR is purpose-built for Bluetooth-enabled portable measurement devices such as remote controls, blood glucose meters, pulseoximeters, thermostats, and smart meters. Its architecture, peripherals, and pre-validated Ethermind stack integration make it ideal for SPP-based wireless serial replacement where ultra-low power and medical-grade reliability are critical. The MSP430BT5190IZCAR combines 256 KB Flash, 12-bit ADC, and four USCI modules to execute both application logic and Bluetooth host duties without external co-processors.
Does the MSP430BT5190IZCAR include an integrated Bluetooth radio?
No, the MSP430BT5190IZCAR does not contain an integrated Bluetooth radio. It is a Bluetooth host controller microcontroller designed to interface with external Bluetooth baseband ICs - specifically TI's CC2560 - via UART or SPI. The "BT" in its part number denotes optimized hardware and firmware support for Bluetooth protocol stacks (e.g., Mindtree Ethermind), not built-in RF transceivers. The MSP430BT5190IZCAR handles link-layer management, HCI, and profile execution while offloading RF functions to the companion CC2560.
What package type and pin count does the MSP430BT5190IZCAR use?
The MSP430BT5190IZCAR uses the 113-pin MicroStar Junior™ BGA (ZQW) package with a 7 mm × 7 mm body size and 0.5 mm pitch. This high-density BGA variant provides 87 GPIOs and full peripheral access in a compact footprint suited for space-constrained portable medical and consumer devices. The ZQW package is distinct from the 100-pin LQFP (PZ) variant and requires BGA-compatible PCB layout and assembly processes. The MSP430BT5190IZCAR pinout includes dedicated XT1/XT2 crystal connections, VCORE regulation pins, and USCI signal routing optimized for CC2560 interfacing.
How does the MSP430BT5190IZCAR achieve ultra-low power consumption?
The MSP430BT5190IZCAR achieves ultra-low power through multiple architectural features: a digitally controlled oscillator (DCO) enabling sub-5 µs wake-up from LPM3, integrated LDO with programmable VCORE, and five low-power modes including LPM4.5 (0.1 µA at 3 V). Its unified clock system separates ACLK (32 kHz RTC), SMCLK (system), and MCLK (CPU) domains to minimize active switching. The MSP430BT5190IZCAR also uses intelligent peripheral activation - e.g., ADC autoscan and DMA - to keep the CPU asleep during data acquisition, further reducing average system current in battery-powered applications.
Is the MSP430BT5190IZCAR pin-compatible with other MSP430x5xx devices?
No, the MSP430BT5190IZCAR is not pin-compatible with standard MSP430x5xx family members such as the MSP430F5438A due to differences in peripheral mapping, power domain routing (e.g., VCORE, DVCC/DVSS splits), and Bluetooth-specific signal assignments (e.g., dedicated USCI configurations for CC2560). While it shares the same 16-bit CPUXV2 core and memory architecture, the ZQW package pinout and function allocation - including XT2, RTCCLK, and SVMOUT signals - are unique to the BT5190 series. Migration requires PCB redesign and firmware adaptation. The MSP430BT5190IZCAR must be treated as a distinct platform within the MSP430x5xx lineage.
