Product details
Overview
MSP430F6459IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 512 KB flash, 66 KB RAM, four 16-bit timers, three USCI modules (UART/IrDA/SPI/I²C), 12-bit ADC with 16 channels, dual 12-bit DACs, RTC, LCD driver for 160 segments, and integrated LDO - deployed in battery-powered sensor systems and portable meters.
For engineers reviewing the MSP430F6459IPZ datasheet, MSP430F6459IPZ pinout, MSP430F6459IPZ application, or MSP430F6459IPZ equivalent, key selection criteria include LDO integration, absence of USB PHY, 74 GPIO count, LQFP-100 packaging, and verified low-power operation down to 1.8 V with 2.0 µA LPM3 current.
Technical Context
The MSP430F6459IPZ implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system includes FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz crystal), and XT2 (up to 32 MHz crystal).
Power management integrates a programmable LDO, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes - enabling 3 µs wake-up from LPM3 and 0.45 µA shutdown (LPM4.5) at 3.0 V. Peripheral set excludes USB but includes full-featured USCI_A/B modules and LCD_B controller with contrast control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with 32-bit hardware multiplier - enables efficient signal processing and real-time control without external math acceleration. |
| Flash / RAM | 512 KB flash + 66 KB RAM - supports complex firmware with large data buffers for sensor fusion or display rendering. |
| Supply Voltage | 1.8 V to 3.6 V - compatible with single-cell Li-ion, alkaline, or coin-cell power sources without external regulators. |
| LPM3 Current | 2.0 µA at 3.0 V - ensures multi-year battery life in always-on monitoring applications with RTC and RAM retention. |
| ADC Resolution | 12-bit, 200 ksps, 16-channel autoscan - captures high-fidelity analog sensor data (12 external + 4 internal) with minimal CPU overhead. |
| I/O Count | 74 GPIO pins - provides ample routing flexibility for multi-sensor interfaces, keypad, LCD, and communication buses. |
| LCD Support | Integrated LCD_B driver for up to 160 segments with programmable contrast - eliminates external display controllers in portable instrumentation. |
| Timers | Four 16-bit timers (TA0/TA1/TA2/TB0) with 3–7 capture/compare registers - supports precise PWM generation, input capture, and time-stamped event logging. |
Pinout & Package
LQFP-100 package (14 mm × 14 mm), thermally enhanced with exposed thermal pad; 100-pin grid, 0.5 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the maximum operating frequency of the MSP430F6459IPZ?
The MSP430F6459IPZ supports a system clock (MCLK) up to 20 MHz, enabled by its integrated FLL and XT2 oscillator supporting crystals up to 32 MHz. At 8 MHz, active-mode current is specified at 295 µA/MHz (typical) with flash execution - confirming stable operation within this range under recommended conditions.
Does the MSP430F6459IPZ include a USB interface?
No, the MSP430F6459IPZ does not include a USB interface. Unlike the MSP430F665x series, the F645x family omits the USB-PHY, USB-PLL, and associated power circuitry. This is confirmed in the Device Comparison table and functional block diagrams - making it suitable for applications where USB is unnecessary and board space/power budget must be optimized.
What package type and pin count does the MSP430F6459IPZ use?
The MSP430F6459IPZ uses a 100-pin LQFP (PZ) package with 14 mm × 14 mm body size and 0.5 mm pitch. This is explicitly documented in the Device Information table and supported by mechanical drawings in Section 11 of the datasheet - providing 74 GPIOs plus power, ground, reset, and oscillator connections.
How much RAM and flash memory does the MSP430F6459IPZ have?
The MSP430F6459IPZ integrates 512 KB of on-chip flash memory and 66 KB of RAM. This is verified in Table 6-1 (Device Comparison) and aligns with the functional block diagram showing "512KB / 384KB Flash" and "64KB / 32KB RAM +2KB RAM". The 66 KB RAM includes both main and auxiliary memory blocks for data buffering and stack allocation.
What low-power modes are supported by the MSP430F6459IPZ?
The MSP430F6459IPZ supports five low-power modes (LPM0–LPM4), including LPM3 (2.0 µA at 3.0 V, RTC + RAM active), LPM3.5 (1.1 µA, RTC + crystal only), and LPM4.5 (0.45 µA, full shutdown). Wake-up from LPM3 occurs in 3 µs (typical), enabled by the DCO's fast stabilization - all values are measured and specified in Section 8.5 of the datasheet.
