Product details
Overview
MSP430F5258IZQER from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller designed as an "always-on" system controller for portable and battery-powered applications. It features 128 KB flash, 32 KB RAM, dual-supply operation (DVCC: 1.8–3.6 V; DVIO: 1.62–1.98 V), four USCI_A and four USCI_B modules, and operates at up to 25 MHz. It targets sensor hub and power-management roles in handsets and tablets.
For engineers reviewing the MSP430F5258IZQER datasheet, MSP430F5258IZQER pinout, MSP430F5258IZQER application, or MSP430F5258IZQER equivalent, key selection criteria include split-rail I/O voltage support, LPM3 standby current (2.3 µA at 3.0 V), 35-DVIO-capable GPIOs, RTC with alarm, and hardware multiplier for sensor fusion algorithms.
Technical Context
The MSP430F5258IZQER 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 supervision, and brownout detection.
It integrates four 16-bit timers (TA0/TA1/TA2/TB0), a 10-bit ADC10_A with 12 channels (10 external + 2 internal), comparator_B (8-channel), 3-channel DMA, and a basic timer with RTC capability - all optimized for deterministic low-latency wake-up from LPM3 in 3.5 µs (typical).

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); identical flash/RAM/peripherals; lacks ADC10_A module. | Suitable where analog sensing is handled externally or not required; preferred for space-constrained PCBs needing thermal pad access. | Select when board layout favors exposed-pad QFN and analog conversion is unnecessary or delegated to external ADC. |
| MSP430F5254IZQER | Same ZQE-80 package and pinout; 128 KB flash but only 16 KB RAM; identical peripheral set including USCI count and timers. | Balances cost and memory for less complex sensor aggregation tasks (e.g., single-sensor BLE beacon vs multi-sensor hub). | Choose when algorithmic complexity is lower and 16 KB RAM suffices - reduces BOM cost without sacrificing I/O or interface flexibility. |
Compared with MSP430F5259IRGC, the MSP430F5258IZQER provides integrated 10-bit ADC capability and BGA packaging suited for high-density layouts; versus MSP430F5254IZQER, it doubles RAM for richer firmware features like dynamic sensor calibration and encrypted log buffering - critical for industrial data integrity.

FAQ
What is the maximum operating frequency of the MSP430F5258IZQER?
The MSP430F5258IZQER supports a maximum system clock frequency of 25 MHz, enabled by its integrated FLL-controlled DCO and optional external XT2 crystal up to 32 MHz. This allows real-time execution of sensor fusion algorithms and high-throughput serial communication without compromising ultra-low-power operation in active mode.
Does the MSP430F5258IZQER support hardware AES encryption?
No, the MSP430F5258IZQER does not include a hardware AES accelerator. It relies on software-based cryptographic libraries for security functions. For applications requiring hardware-accelerated encryption, consider TI's MSP432E4 or CC26xx series - the MSP430F5258IZQER prioritizes ultra-low-power analog integration and deterministic real-time control over cryptographic throughput.
What are the valid supply voltage ranges for DVCC and DVIO on the MSP430F5258IZQER?
The MSP430F5258IZQER requires DVCC between 1.8 V and 3.6 V for core logic and analog modules, and DVIO between 1.62 V and 1.98 V exclusively for I/O banks P1–P4, P7, and PJ. These separate rails enable seamless interfacing with 1.8-V application processors and sensors without external level shifters - a defining feature of the MSP430F525x family.
How many external interrupt-capable pins does the MSP430F5258IZQER have?
The MSP430F5258IZQER supports up to 16 external interrupt-capable pins, distributed across DVIO-supplied ports P1, P2, P3, and P4. Each of these pins can generate wake-up events from LPM3 or LPM4 modes, enabling responsive, low-latency reaction to sensor triggers or communication activity without continuous polling.
Is the MSP430F5258IZQER pin-compatible with the MSP430F5252IZQE?
Yes, the MSP430F5258IZQER is pin-compatible with the MSP430F5252IZQE - both use the same MicroStar Junior™ BGA-80 (ZQE) package with identical pin assignments and electrical characteristics. However, the MSP430F5258IZQER doubles the RAM (32 KB vs 16 KB) and adds the ADC10_A module, making it a functional superset for designs requiring enhanced data processing or analog sensing.
