Product details
Overview
MSP430F5259IZQER from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller designed as an "always-on" system controller for portable electronics. It features 128 KB flash, 32 KB RAM, dual-supply operation (DVCC: 1.8–3.6 V; DVIO: 1.62–1.98 V), and supports up to 35 general-purpose I/Os with 16 external interrupts - enabling seamless interface to application processors without level shifters in sensor hub and power-management applications.
For engineers reviewing the MSP430F5259IZQER datasheet, MSP430F5259IZQER pinout, MSP430F5259IZQER application, or MSP430F5259IZQER equivalent, key selection criteria include its split-rail I/O architecture, LPM3 standby current of 2.3 µA at 3.0 V, 3.5 µs wake-up time, four USCI_A and four USCI_B modules, and RTC-integrated basic timer for autonomous monitoring.
Technical Context
The MSP430F5259IZQER implements a unified clock system with FLL stabilization, VLO and REFO internal sources, XT1 (32-kHz crystal), and XT2 (up to 32-MHz HF crystal). Its power management includes a programmable LDO core regulator, supply voltage supervision, and brownout detection across both DVCC and DVIO domains.
It integrates four 16-bit timers (TA0/TA1/TA2/TB0), a 10-bit ADC10_A with 12 channels (10 external + 2 internal), hardware multiplier (MPY32), 3-channel DMA, comparator_B (8 channels), and dual-domain I/O ports - where P1–P4/P7 are DVIO-powered (1.8 V) and P5–P6/PJ are DVCC-powered (up to 3.6 V), enabling independent voltage domain control for low-power peripheral interfacing.

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 |
|---|---|---|---|
| MSP430F5259IRGC | VQFN-64 package (9 mm × 9 mm); DVCC/DVIO I/O mapping identical; same flash/RAM/timers/USCI count | Preferred for prototyping and PCBs requiring exposed thermal pad and hand-solderability | Select when thermal performance or assembly simplicity outweighs board space constraints. |
| MSP430F5255IZQER | Identical ZQE package and pinout; differs only in BSL type (UART vs I²C) and absence of ADC10_A (N/A in device comparison table) | Suitable where analog sensing is unnecessary but same low-power serial control is required | Choose when cost sensitivity and lack of ADC functionality align with system requirements. |
Compared with MSP430F5259IRGC, the MSP430F5259IZQER offers identical functionality in a smaller 5 mm × 5 mm BGA footprint - critical for space-constrained wearables. Against MSP430F5255IZQER, it adds 10-bit ADC10_A with 12 channels, enabling analog sensor integration without external converters.

FAQ
What is the primary supply voltage range for MSP430F5259IZQER?
The MSP430F5259IZQER operates with a primary digital supply (DVCC) from 1.8 V to 3.6 V and a separate low-voltage I/O supply (DVIO) from 1.62 V to 1.98 V. This dual-rail architecture allows the MSP430F5259IZQER to interface directly with 1.8-V application processors without external level translation, while maintaining higher core voltage for performance and noise immunity.
How many hardware serial interfaces does MSP430F5259IZQER support?
The MSP430F5259IZQER supports eight hardware serial interfaces: four USCI_A modules (each configurable for UART, IrDA, or SPI) and four USCI_B modules (each configurable for I²C or SPI). This enables concurrent, dedicated communication paths - for example, four I²C links to sensors and four SPI links to displays or memory - without CPU overhead or bus arbitration.
What is the standby current consumption of MSP430F5259IZQER in LPM3 mode?
In LPM3 (standby) mode with RTC, watchdog, supply supervisor active and full RAM retention, the MSP430F5259IZQER consumes 2.3 µA at 3.0 V (typical), as specified in TI SLAS903D. This ultra-low current enables multi-week battery life in always-on monitoring applications, and the device wakes in 3.5 µs to resume full operation.
Does MSP430F5259IZQER include an analog-to-digital converter?
Yes, the MSP430F5259IZQER integrates a 10-bit ADC10_A with 12 input channels (10 external, 2 internal), internal reference, and sample-and-hold. It supports up to 200 ksps conversion rate and is powered from the AVCC/AVSS domain - a key differentiator from the MSP430F5255IZQER, which omits this ADC entirely.
What package type and pin count does MSP430F5259IZQER use?
The MSP430F5259IZQER uses the MicroStar Junior™ BGA package (ZQE), with 80 pins and a 5 mm × 5 mm body size. This compact, fine-pitch BGA is optimized for high-density portable designs and shares pin compatibility with other MSP430F525x family members in the ZQE variant, including identical DVIO/DVCC domain assignments.
