Product details
Overview
MSP430F5658IZQWT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 384 KB flash, 32 KB + 2 KB RAM, USB 2.0 full-speed interface, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, and integrated LCD driver for up to 160 segments. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable meters.
For engineers reviewing the MSP430F5658IZQWT datasheet, MSP430F5658IZQWT pinout, MSP430F5658IZQWT application, or MSP430F5658IZQWT equivalent, key selection criteria include USB integration without external PHY, LPM3.5 RTC operation at 1.1 µA, 3 µs wake-up time, and MicroStar Junior BGA (113-pin) packaging for space-constrained designs.
Technical Context
The MSP430F5658IZQWT implements a 16-bit RISC CPU with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) with programmable LDO core regulation.
Peripherals include three USCIs (two UART/IrDA/SPI + one I²C/SPI), four 16-bit timers (TA0 with 5 CC, TA1/TA2 with 3 CC each, TB0 with 7 CC), RTC_B with alarm and battery backup, and CRC16 engine. USB functionality uses integrated PHY, PLL, and dual-voltage (3.3 V/1.8 V) power system.
Key Specifications

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 |
|---|---|---|---|
| MSP430F5659IZQWT | 512 KB flash, 64 KB + 2 KB RAM - +128 KB flash, +32 KB RAM vs. MSP430F5658IZQWT | Required for larger firmware images (e.g., USB HID + bootloader + encryption stack) | Select when firmware size exceeds 384 KB or extended RAM is needed for buffering USB transactions. |
| MSP430F6658IPZ | LQFP-100 package (14 mm × 14 mm); includes integrated 3.3-V LDO - differs from ZQW BGA and lacks USB | Suitable for cost-sensitive, non-USB designs where PCB real estate allows larger package | Choose for legacy LQFP layouts or when USB is unnecessary and LDO simplifies power design. |
Compared with MSP430F5658IZQWT, MSP430F5659IZQWT offers higher memory capacity for feature-rich firmware, while MSP430F6658IPZ trades USB and BGA density for LQFP manufacturability and integrated LDO - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum system clock frequency supported by the MSP430F5658IZQWT?
The MSP430F5658IZQWT supports a maximum system clock frequency of 20 MHz. This is achieved using the integrated FLL with XT2 (high-frequency crystal) up to 32 MHz or DCO calibration. The 20-MHz rating reflects guaranteed operation across voltage (1.8 V–3.6 V) and temperature ranges per TI SLAS700E specifications.
Does the MSP430F5658IZQWT include an integrated LDO regulator?
No, the MSP430F5658IZQWT does not include an integrated 3.3-V LDO regulator. Unlike the MSP430F645x/F665x series, the F565x family relies on external regulation. Power must be supplied to DVCC and AVCC rails within 1.8 V–3.6 V, with separate analog and digital ground connections required for optimal ADC/DAC performance.
Can the MSP430F5658IZQWT operate in real-time clock mode while powered down?
Yes, the MSP430F5658IZQWT supports RTC_B operation in LPM3.5 mode with crystal (32.768 kHz) active and main power removed. In this state, it draws 1.1 µA at 3.0 V and retains full RTC functionality including calendar, alarms, and periodic interrupts - ideal for time-critical wake-up in battery-backed systems.
How many USB endpoints does the MSP430F5658IZQWT support?
The MSP430F5658IZQWT supports eight input and eight output USB endpoints. These are configurable via firmware to implement standard USB classes (e.g., CDC, HID, MSC) and handle concurrent control, bulk, and interrupt transfers - sufficient for composite device implementations like meter + HID keyboard.
What is the pin count and package type of the MSP430F5658IZQWT?
The MSP430F5658IZQWT uses a MicroStar Junior™ BGA package with 113 terminals in a 7 mm × 7 mm body. It provides 74 general-purpose I/O pins plus dedicated USB, crystal, reset, and power terminals - optimized for high-density portable designs where LQFP is impractical.
