Product details
Overview
MSP430F6458IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in LQFP-100 package, featuring 384 KB flash, 34 KB RAM, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, USB-free architecture, integrated LCD driver (160 segments), and seven 16-bit timers - deployed in battery-powered sensor nodes and portable meters requiring sub-2 µA LPM3 standby current.
For engineers reviewing the MSP430F6458IPZ datasheet, MSP430F6458IPZ pinout, MSP430F6458IPZ application, or MSP430F6458IPZ equivalent, key selection criteria include absence of USB PHY, presence of integrated LDO, RTC with battery backup, 74 GPIO count, and compatibility with TI's MSP430F645x family toolchain and firmware libraries.
Technical Context
The MSP430F6458IPZ implements a CPUXV2 16-bit RISC core 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), enabling precise timing control across five low-power modes.
Power management includes a fully integrated programmable LDO, supply voltage supervisor (SVS), brownout reset (BOR), and dynamic core voltage regulation. Peripheral interconnect uses six-channel DMA and three USCIs - two UART/IrDA/SPI-capable (USCI_A) and one I²C/SPI-capable (USCI_B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | CPUXV2 16-bit RISC with 32-bit hardware multiplier - enables efficient fixed-point math for sensor fusion and motor control loops. |
| Flash / RAM | 384 KB flash + 34 KB RAM - sufficient for complex real-time firmware with bootloader, calibration tables, and data logging buffers. |
| ADC Performance | 12-bit, 200 ksps, 16-channel autoscan (12 external + 4 internal) - supports simultaneous multi-sensor acquisition without CPU overhead. |
| Low-Power Modes | LPM3: 2.0 µA at 3.0 V; LPM3.5 (RTC active): 1.1 µA; LPM4.5: 0.45 µA - enables >10-year battery life in metering applications. |
| Timer Resources | Four 16-bit timers: TA0 (5 CC), TA1/TA2 (3 CC each), TB0 (7 CC) - supports PWM generation, input capture, quadrature decoding, and RTC calendar functions. |
| LCD Driver | Integrated LCD_B controller driving up to 160 segments with contrast control - eliminates external display driver IC in handheld instruments. |
| I/O Count | 74 GPIO pins with configurable drive strength, Schmitt-trigger inputs, and interrupt capability on all ports - supports dense peripheral interfacing and keypad scanning. |
Pinout & Package
LQFP-100 (14 mm × 14 mm) package with exposed thermal pad; 100-pin square grid, 0.5 mm pitch, RoHS-compliant lead finish.
| 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. |
| P1.x–P9.x, PJ.x | General-purpose I/O with peripheral multiplexing | 74 total GPIOs distributed across 10 ports; each supports interrupt-on-change, pull-up/down, and peripheral function mapping (e.g., USCI, ADC, timer). |
| XT1IN/XT1OUT | Low-frequency crystal oscillator terminals | Supports 32.768 kHz watch crystal for RTC accuracy ±20 ppm; essential for timekeeping in thermostats and energy meters. |
| XT2IN/XT2OUT | High-frequency crystal oscillator terminals | Accepts crystals up to 32 MHz for system clock scaling; enables high-speed USB-free communication or fast ADC sampling. |
| DVCC/DVSS, AVCC/AVSS | Digital/analog power and ground rails | Separate analog/digital supplies reduce noise coupling; AVCC must be ≥ DVCC for ADC reference stability and linearity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LDO regulator | Programmable core voltage (1.3–3.0 V) reduces external BOM count and improves PSRR for analog peripherals. |
| Real-time clock with battery backup | RTC_B module retains time/date during main power loss using VBAT; supports alarm interrupts and calendar mode. |
| Hardware CRC16 engine | Offloads checksum computation from CPU - accelerates firmware validation and secure boot integrity checks. |
| Memory Integrity Detection (MID) | Dedicated hardware monitors flash/RAM for bit flips; triggers NMI on corruption - critical for safety-aware metering firmware. |
| USB-free architecture | Omits USB PHY and transceiver - lowers cost, power, and EMI in non-USB applications like industrial sensors and HVAC controllers. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6459IPZ | 512 KB flash, 66 KB RAM, same peripherals and pinout - higher memory capacity for larger firmware or data buffers. | Suitable where extended firmware features (e.g., OTA updates, advanced diagnostics) require more flash/RAM. | Select when future-proofing against firmware growth or adding cryptographic libraries. |
| MSP430F5358IPZ | No integrated LCD driver, no USB, identical LDO and RTC; 384 KB flash, 34 KB RAM, same LQFP-100 package. | Better suited for non-display applications (e.g., sensor transmitters, remote I/O) where LCD_B is unused. | Choose to reduce cost and simplify layout when display functionality is unnecessary. |
Compared with MSP430F6458IPZ, the MSP430F6459IPZ offers scalable memory headroom without changing PCB layout, while the MSP430F5358IPZ removes LCD_B to lower system cost and power in headless sensor nodes - both retain identical low-power operation and peripheral set except display support.

FAQ
What is the maximum system clock frequency supported by the MSP430F6458IPZ?
The MSP430F6458IPZ supports a maximum system clock (MCLK) frequency of 20 MHz, achieved using the FLL with XT2 crystal up to 32 MHz or internal DCO calibration. This allows deterministic real-time response for time-critical tasks such as motor commutation or high-speed ADC sampling without violating timing margins.
Does the MSP430F6458IPZ include a USB interface?
No, the MSP430F6458IPZ does not include a USB interface or USB PHY. It belongs to the MSP430F645x subfamily, which omits USB functionality to reduce cost and power consumption - unlike the MSP430F665x series that integrates full-speed USB 2.0.
How many analog input channels does the 12-bit ADC on the MSP430F6458IPZ support?
The MSP430F6458IPZ features the ADC12_A module with 16 total input channels: 12 external analog inputs (A0–A11) and 4 internal sources (temperature sensor, VREF generator, supply voltage, and VMID). All channels are accessible via autoscan mode for unattended multi-channel acquisition.
What is the standby current consumption of the MSP430F6458IPZ in LPM3 mode?
In LPM3 mode (watchdog + crystal RTC active, full RAM retention), the MSP430F6458IPZ consumes 2.0 µA at 3.0 V (typical), as specified in the SLAS700E datasheet Section 8.5. This ultra-low quiescent current enables decade-long operation on coin-cell batteries in maintenance-free sensor deployments.
Is the MSP430F6458IPZ pin-compatible with other devices in the MSP430F645x family?
Yes, the MSP430F6458IPZ is pin-compatible with the MSP430F6459IPZ in the LQFP-100 package - sharing identical pin functions, electrical characteristics, and footprint. This allows direct replacement for memory-scaling upgrades without PCB redesign.
