Product details
Overview
MSP430F5436AIZQWR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 192 KB flash, 16 KB RAM, 12-bit ADC (14 external + 2 internal channels), four USCI modules (UART/IrDA/SPI/I²C), three 16-bit timers, RTC, hardware multiplier, and DMA-designed for battery-powered sensor systems and portable measurement devices.
For engineers reviewing the MSP430F5436AIZQWR datasheet, MSP430F5436AIZQWR pinout, MSP430F5436AIZQWR application, or MSP430F5436AIZQWR equivalent, key selection considerations include its MicroStar Junior™ BGA-113 package, 3.6 V to 1.8 V supply range, LPM4.5 shutdown current of 0.1 µA, 3.5 µs wakeup from LPM3, and integrated LDO with programmable core voltage.
Technical Context
The MSP430F5436AIZQWR implements a CPUXV2 core with constant generators and extended memory addressing, supporting up to 25-MHz system clock via FLL-stabilized DCO or external crystals (up to 32 MHz). Its unified clock system provides MCLK, SMCLK, and ACLK sourced from VLO, REFO, XT1, or XT2.
Power management includes programmable LDO regulation, brownout reset (BOR), supply voltage supervisor (SVS/SVM), and five low-power modes (LPM0–LPM4.5) with full RAM retention in LPM3/LPM4. The ADC12_A module supports autoscan, sample-and-hold, and internal reference at 200 ksps.

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 |
|---|---|---|---|
| MSP430F5438AIZQW | 256 KB flash (vs. 192 KB), identical RAM, peripherals, package, and pinout | Preferred where firmware complexity requires larger code space or future-proofing against feature expansion | Select when additional flash headroom is needed without changing PCB layout or driver software |
| MSP430F5436AIPZ | LQFP-100 package (14 mm × 14 mm) vs. ZQW BGA; same flash/RAM/peripherals; 87 I/O pins retained | Better suited for prototyping, manual assembly, or designs requiring thermal relief or optical inspection access | Choose for development boards, low-volume production, or environments where BGA rework is impractical |
Compared with MSP430F5438AIZQW, the MSP430F5436AIZQWR offers 64 KB less flash but identical low-power performance, peripheral set, and BGA footprint-making it optimal for cost-sensitive, volume production of fixed-function sensor nodes.

FAQ
What is the maximum system clock frequency supported by the MSP430F5436AIZQWR?
The MSP430F5436AIZQWR supports up to 25 MHz system clock frequency via its digitally controlled oscillator (DCO) with FLL stabilization. It also accepts external high-frequency crystals up to 32 MHz on XT2, enabling precise timing for high-speed communication or signal processing tasks while maintaining full peripheral functionality at rated voltage.
Does the MSP430F5436AIZQWR support in-system programming without external voltage?
Yes, the MSP430F5436AIZQWR supports serial onboard programming (SBP) through its Spy-Bi-Wire (SBW) interface using only the TEST and SBWTCK pins-no external programming voltage is required. This enables field firmware updates and eliminates the need for dedicated HV programming circuitry on the target board.
How many analog input channels does the ADC12_A module provide on the MSP430F5436AIZQWR?
The ADC12_A module on the MSP430F5436AIZQWR provides 16 total input channels: 14 external analog inputs (A0–A15, with A10/A11 reserved) and 2 internal channels (temperature sensor and VCC/2 reference). All channels are accessible via the same 12-bit SAR architecture with autoscan and sample-and-hold capability.
Is the MSP430F5436AIZQWR pin-compatible with other devices in the MSP430F543xA family?
Yes, the MSP430F5436AIZQWR shares identical pinout and signal mapping with MSP430F5438AIZQW and MSP430F5419AIZQW in the ZQW package-confirmed by TI's functional block diagrams and pin configuration tables. This allows direct substitution within the same BGA footprint when flash size or peripheral count permits.
What low-power mode achieves the lowest current consumption on the MSP430F5436AIZQWR?
The MSP430F5436AIZQWR achieves its lowest active current in LPM4.5 (shutdown mode) at 0.1 µA typical at 3.0 V, with full RAM retention and supply supervisor enabled. Unlike LPM4, LPM4.5 disables the LDO and stops all clocks-including the VLO-requiring a reset to resume operation.
