Texas Instruments MSP430F5359IPZR

Overview

MSP430F5359IPZR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 512 KB flash, 66 KB RAM, four 16-bit timers, a 12-bit 200-ksps ADC with 16 channels (12 external + 4 internal), two 12-bit DACs, and integrated LDO regulator - deployed in battery-powered sensor nodes and portable meters requiring sub-2-µA standby current and 3-µs wake-up.

For engineers reviewing the MSP430F5359IPZR datasheet, MSP430F5359IPZR pinout, MSP430F5359IPZR application, or MSP430F5359IPZR equivalent, key selection criteria include LPM3 current (2.0 µA at 3.0 V), RTC-B module with battery backup, absence of USB and LCD peripherals, and LQFP-100 package compatibility with industrial-grade I/O count (74 pins).

Technical Context

The MSP430F5359IPZR implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL, VLO, REFO, XT1 (32-kHz crystal), and XT2 (up to 32-MHz crystal) sources, 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 - USCI_Ax for UART/IrDA/SPI and USCI_Bx for I²C/SPI - with no USB or LCD controller present.

FAQ

What is the maximum system clock frequency supported by the MSP430F5359IPZR?

The MSP430F5359IPZR supports a maximum system clock frequency of 20 MHz. This is achieved using the integrated FLL with XT2 crystal (up to 32 MHz) or external clock source. The CPUXV2 core executes instructions at this rate, enabling real-time processing of sensor data and communication protocols without performance bottlenecks in the MSP430F5359IPZR.

Does the MSP430F5359IPZR include USB or LCD peripheral support?

No, the MSP430F5359IPZR does not include USB or LCD peripheral modules. Unlike the MSP430F565x or MSP430F645x families, the MSP430F5359IPZR omits both the USB-PHY and LCD_B controllers. This makes the MSP430F5359IPZR ideal for cost- and power-sensitive applications where those peripherals are unnecessary - such as standalone sensor nodes or metering devices using external display drivers.

What are the key low-power modes and their typical current consumption for the MSP430F5359IPZR?

The MSP430F5359IPZR features five low-power modes. LPM3 draws 2.0 µA at 3.0 V with RTC and crystal active; LPM3.5 (RTC-only) consumes 1.1 µA; LPM4.5 (shutdown) draws 0.45 µA. All modes retain full RAM content. These values are measured with core LDO enabled and no external loads - confirming the MSP430F5359IPZR's suitability for decade-long battery operation in maintenance-free deployments.

How many capture/compare registers are available across the timer modules in the MSP430F5359IPZR?

The MSP430F5359IPZR includes four 16-bit timers: Timer_A0 has five capture/compare registers, while Timer_A1 and Timer_A2 each have three, and Timer_B0 has seven. This totals 18 capture/compare registers - sufficient for simultaneous PWM generation, input capture (e.g., pulse width measurement), and interval timing tasks without resource contention in the MSP430F5359IPZR.

Is the MSP430F5359IPZR pin-compatible with other devices in the MSP430F5xx family?

Yes, the MSP430F5359IPZR in LQFP-100 package shares identical pinout with MSP430F5358IPZR, MSP430F5659IPZR, and MSP430F6459IPZR. Signal mapping, power/ground locations, and debug interface pins are consistent across these 100-pin variants - enabling hardware reuse and migration paths within the same PCB footprint for the MSP430F5359IPZR.
