MSP430BT5190IZQWT

Application Specific Microcontrollers Overview

The MSP430BT5190IZQWT is a 16-bit mixed-signal microcontroller from Texas Instruments, based on the MSP430 core. It integrates 256 KB of flash program memory and 16 KB of RAM within a 113-pin VFBGA package (Microstar Junior). The device supports a maximum clock frequency of 25 MHz and operates on a supply voltage range of 1.8 V to 3.6 V. Key peripherals include an 87 I/O count, a 12-bit ADC, and communication interfaces such as I2C, IrDA, SCI, SPI, and UART/USART. It is designed for low-power applications requiring Bluetooth connectivity.

Application Specific Microcontrollers Feature Summary

• 256 KB Flash memory and 16 KB RAM for code and data storage
• 12-bit Analog-to-Digital Converter (ADC) for signal acquisition
• Supports multiple serial communication protocols including SPI, I2C, and UART

Application Specific Microcontrollers Applications

• Bluetooth-enabled sensor nodes
• Wireless medical devices
• Smart home automation controllers
• Industrial wireless monitoring systems

Application Specific Microcontrollers Part Context

This component belongs to the MSP430BT series, which combines the ultra-low-power MSP430 microcontroller with a Bluetooth radio. It is distinct from standard MSP430F or MSP430G series parts by its integrated wireless capability. The 'IZQWT' suffix indicates the specific package type (VFBGA), temperature range, and tape-and-reel packaging configuration.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements may be limited due to the integrated Bluetooth radio. Consider MSP430F series MCUs paired with external Bluetooth modules if the radio integration is not required. Verify compatibility with existing firmware libraries designed for the MSP430BT architecture.
