Product details
Overview
MSP430F5658IPZ from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with USB 2.0 interface, 384 KB flash, 32 KB + 2 KB RAM, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, and integrated LCD driver for up to 160 segments - deployed in battery-powered sensor nodes and portable meters.
For engineers reviewing the MSP430F5658IPZ datasheet, MSP430F5658IPZ pinout, MSP430F5658IPZ application, or MSP430F5658IPZ equivalent, this page delivers verified functional specs, LQFP-100 package mapping, USB-capable MCU architecture details, and validated alternative options for low-power embedded designs requiring real-time control and analog integration.
Technical Context
The MSP430F5658IPZ implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL stabilization, VLO/REFO internal sources, XT1 (32-kHz crystal), and XT2 (up to 32-MHz crystal) - enabling precise timing across five low-power modes.
Peripherals include three USCI modules (USCI_A0–A2 for UART/IrDA/SPI; USCI_B0–B2 for I²C/SPI), six-channel DMA, RTC_B with battery backup, CRC16 engine, and Comp_B - all operating under programmable LDO-regulated core voltage (1.8–3.6 V) with brownout detection and fast 3-µs wake-up from LPM3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with 32-bit hardware multiplier - enables efficient signal processing and math-intensive firmware without external coprocessor. |
| Flash / RAM | 384 KB flash + 32 KB + 2 KB RAM - supports large firmware images, data logging buffers, and USB descriptor tables in single-chip USB device implementations. |
| ADC Performance | 12-bit ADC with 200 ksps sampling, autoscan, and 16 channels (12 external + 4 internal) - allows simultaneous multi-sensor acquisition with built-in temperature sensor and VMID reference. |
| USB Interface | Full-speed USB 2.0 PHY with integrated 3.3-V/1.8-V power system and USB-PLL - eliminates external transceiver and voltage regulators for self-powered or bus-powered USB devices. |
| Low-Power Modes | LPM3.5 (RTC active): 1.1 µA at 3.0 V; LPM4.5 (shutdown): 0.45 µA - extends coin-cell battery life to years in always-on monitoring applications. |
| I/O Count | 74 GPIO pins in LQFP-100 package - provides ample routing for sensor interfaces, display segments, USB D+/D−, and debug (JTAG/SBW) without multiplexing conflicts. |
| Timer Resources | Four 16-bit timers: TA0 (5 CC), TA1/TA2 (3 CC each), TB0 (7 CC) - supports complex PWM generation, input capture for motor control, and RTC alarm scheduling. |
Pinout & Package
LQFP-100 (PZ) package, 14 mm × 14 mm body size, 0.5-mm pitch, exposed thermal pad - compatible with standard reflow profiles and industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / Spy-Bi-Wire debug I/O | Single-pin JTAG-compatible debug interface; enables in-system programming and real-time debugging without dedicated TMS/TCK pins. |
| USB_DP / USB_DM | USB 2.0 full-speed differential data pair | Direct connection to USB connector; requires 1.5-kΩ pull-up on DP for device enumeration - no external transceiver needed. |
| AVCC / AVSS | Analog power supply and ground | Separate analog domain for ADC/DAC/LCD; must be decoupled independently to maintain 12-bit linearity and noise immunity. |
| XIN / XOUT | Low-frequency crystal oscillator terminals (XT1) | Supports 32.768-kHz watch crystal for RTC accuracy ±20 ppm; essential for timekeeping in LPM3.5 mode. |
| P1.x – P9.x, PJ.x | General-purpose I/O ports (74 total) | Configurable as digital I/O, peripheral function pins (e.g., USCI, Timer), or LCD segment/com drivers - mapped via PxSEL registers. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB-PHY and power system | Eliminates external USB transceiver and dual LDOs - reduces BOM count by ≥4 components and PCB area by >25 mm². |
| Dual synchronized 12-bit DACs | Enables simultaneous analog output generation (e.g., bias voltage + reference ramp) with <±1 LSB INL - critical for closed-loop sensor calibration. |
| Hardware CRC16 engine | Offloads flash integrity checking and communication packet validation from CPU - preserves low-power operation during firmware updates or wireless data transfer. |
| Memory Integrity Detection (MID) | Automatically detects bit flips in flash/RAM using ECC-like algorithm - enhances reliability in safety-aware metering and industrial control firmware. |
| Programmable LDO core regulator | Adjusts DVCC from 1.8 V to 3.6 V dynamically - allows trade-off between performance (higher clock speed) and battery life (lower leakage). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power USB-capable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5659IPZ | 512 KB flash, 64 KB + 2 KB RAM - +128 KB flash and +32 KB RAM vs. MSP430F5658IPZ | Required for larger USB device descriptors, complex USB class stacks (e.g., MSC), or extended firmware feature sets | Select when firmware image size exceeds 384 KB or RAM usage exceeds 34 KB - same pinout and peripheral set. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5658IPZ?
The MSP430F5658IPZ supports a maximum system clock frequency of 20 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization or through the high-frequency crystal oscillator (XT2) up to 32 MHz. This allows real-time execution of USB full-speed protocols, 200-ksps ADC sampling, and deterministic timer operations - all confirmed in Section 8.20 (DCO Frequency) and Section 8.17 (XT2) of the SLAS700E datasheet.
Does the MSP430F5658IPZ include an integrated USB physical layer?
Yes, the MSP430F5658IPZ integrates a full-speed USB 2.0 PHY, 3.3-V and 1.8-V USB power system, and USB-PLL - eliminating the need for external transceivers or voltage regulators. This is explicitly documented in the "Features" section and Figure 4-2 (Functional Block Diagram) of the SLAS700E datasheet, confirming native USB device functionality in the LQFP-100 package.
How many I/O pins does the MSP430F5658IPZ provide in the LQFP-100 package?
The MSP430F5658IPZ provides 74 general-purpose I/O pins in the LQFP-100 (PZ) package, as specified in Table 6-1 (Device Comparison) and confirmed across functional block diagrams (Figures 4-1 to 4-3) in the SLAS700E datasheet. These include P1–P9, PJ, and dedicated USB/XTAL/debug pins - all accessible on the 100-pin footprint.
What low-power modes are available on the MSP430F5658IPZ, and what are their typical currents?
The MSP430F5658IPZ supports five low-power modes: LPM3 (2.0 µA at 3.0 V), LPM3.5 (RTC active, 1.1 µA at 3.0 V), and LPM4.5 (shutdown, 0.45 µA at 3.0 V) - all verified in Section 8.5 of SLAS700E. These modes enable multi-year battery life in always-on sensing applications while retaining RAM retention, RTC operation, or full shutdown with fast 3-µs wake-up from LPM3.
Is the MSP430F5658IPZ pin-compatible with other members of the MSP430F565x family?
Yes, the MSP430F5658IPZ is pin-compatible with MSP430F5659IPZ in the LQFP-100 package - sharing identical pin functions, electrical characteristics, and package dimensions per Table 6-1 and Section 7.1 (Pin Diagrams) of SLAS700E. This allows drop-in replacement for flash/RAM scaling without PCB redesign.
