Product details
Overview
MSP430F5658IZQWR 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 MSP430F5658IZQWR datasheet, MSP430F5658IZQWR pinout, MSP430F5658IZQWR application, or MSP430F5658IZQWR equivalent, key selection criteria include USB integration without external PHY, LPM3.5 RTC operation at 1.1 µA, 3 µs wake-up from standby, 74 GPIO count, and MicroStar Junior BGA (113-pin, 7 mm × 7 mm) packaging for space-constrained designs.
Technical Context
The MSP430F5658IZQWR implements a CPUXV2 core with constant generators and 16-bit RISC architecture, supporting up to 20-MHz system clock via FLL-stabilized DCO or external crystals (XT1 up to 32 kHz, XT2 up to 32 MHz). Its unified clock system includes VLO and REFO internal sources for autonomous low-power operation.
Peripheral integration centers on three USCIs (USCI_A0–A2 for UART/IrDA/SPI; USCI_B0–B2 for I²C/SPI), six-channel DMA, RTC_B with alarm and battery backup, hardware multiplier for 32-bit operations, and memory integrity detection (MID). The device lacks integrated LDO-unlike F645x/F535x variants-relying on external regulation.
Key Specifications

FAQ
What is the operating voltage range for the MSP430F5658IZQWR?
The MSP430F5658IZQWR operates from 1.8 V to 3.6 V. This wide supply range supports direct connection to single-cell Li-ion, Li-polymer, or two-cell alkaline batteries without intermediate regulation-enabling simplified power architecture in portable devices. The device maintains full functionality including USB and ADC operation across this entire range.
Does the MSP430F5658IZQWR include an integrated LDO regulator?
No, the MSP430F5658IZQWR does not include an integrated LDO regulator. Unlike the MSP430F645x/F535x variants, it requires externally supplied DVCC and AVCC rails. This design choice reduces die area and power loss, aligning with applications where system-level regulation is already present or preferred for efficiency control.
What USB speed and features does the MSP430F5658IZQWR support?
The MSP430F5658IZQWR supports full-speed USB 2.0 (12 Mbps) with integrated PHY, on-chip 3.3-V and 1.8-V USB power system, USB-PLL, and eight configurable endpoints (four IN, four OUT). It handles enumeration, control transfers, and bulk/intrerrupt traffic without external transceiver components-reducing bill-of-materials and PCB complexity.
How many I/O pins does the MSP430F5658IZQWR provide, and what packaging is used?
The MSP430F5658IZQWR provides 74 general-purpose I/O pins in the MicroStar Junior™ BGA (ZQW) package-113-terminal, 7 mm × 7 mm, 0.5-mm pitch. This high I/O density in a compact footprint supports complex peripheral interfacing while minimizing PCB area, ideal for handheld and wearable form factors.
What low-power modes are available on the MSP430F5658IZQWR, and what is the lowest current draw?
The MSP430F5658IZQWR supports five low-power modes (LPM0–LPM4.5). The lowest active-retention mode is LPM3.5 (RTC active with 32-kHz crystal), drawing 1.1 µA at 3.0 V. The absolute minimum is LPM4.5 (full shutdown), consuming 0.45 µA at 3.0 V-enabling multi-year operation on coin-cell batteries in maintenance-free sensor applications.
