Texas Instruments MSP430F5359IPZ

Overview

MSP430F5359IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in LQFP-100 package, featuring 512 KB flash, 66 KB RAM, four 16-bit timers, three USCI modules (UART/IrDA/SPI/I²C), 12-bit ADC with 16 channels, two 12-bit DACs, RTC with battery backup, and integrated LDO. It targets battery-powered sensor nodes and portable metering systems requiring sub-2 µA standby current and 3 µs wake-up.

For engineers reviewing the MSP430F5359IPZ datasheet, MSP430F5359IPZ pinout, MSP430F5359IPZ application, or MSP430F5359IPZ equivalent, key selection criteria include LQFP-100 pin count, absence of USB and LCD peripherals, 1.8–3.6 V operation, 20-MHz max system clock, and compatibility with MSP430F5xx family toolchains and firmware libraries.

Technical Context

The MSP430F5359IPZ implements the CPUXV2 core with 16-bit RISC architecture, constant generators, and unified clock system including FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management integrates an on-chip LDO with programmable core voltage, supply supervision, brownout reset, and five low-power modes (LPM0–LPM4.5).

Peripherals are memory-mapped and synchronized via a 6-channel DMA controller. The device supports full JTAG and Spy-Bi-Wire debugging, onboard serial programming without external voltage, and hardware multiplier for 32-bit operations. All I/O pins feature Schmitt-trigger inputs and configurable drive strength.

FAQ

Does MSP430F5359IPZ support USB functionality?

No, MSP430F5359IPZ does not include a USB module. Unlike the MSP430F565x or MSP430F665x series, this device omits the integrated USB-PHY, USB-PLL, and endpoint buffers. Its USCI modules support UART, IrDA, SPI, and I²C only. For USB-capable alternatives in the same family, consider MSP430F5659IPZ or MSP430F6659IPZ.

What is the maximum operating frequency of MSP430F5359IPZ?

The MSP430F5359IPZ supports a maximum system clock frequency of 20 MHz, achieved using the FLL with XT2 (high-frequency crystal) or internal DCO. This is confirmed in the device's functional block diagram and Section 8.20 (DCO Frequency) of the SLAS700E datasheet, where fDCO,max = 20 MHz under recommended operating conditions.

Is MSP430F5359IPZ pin-compatible with other devices in the F535x series?

Yes, MSP430F5359IPZ is pin-compatible with MSP430F5358IPZ in the LQFP-100 package. Both share identical pin functions, electrical characteristics, and memory map layout. Differences are limited to flash (512 KB vs. 384 KB) and RAM (66 KB vs. 34 KB), making them drop-in replacements where firmware fits within the smaller memory footprint.

Does MSP430F5359IPZ include an LCD controller?

No, MSP430F5359IPZ does not integrate an LCD driver. The LCD_B module present in MSP430F645x and MSP430F665x devices is omitted from the F535x series. This distinguishes MSP430F5359IPZ from MSP430F6459IPZ, which supports up to 160 segments. Software-based segment control is possible but requires external drivers or GPIO toggling.

What debug interfaces are supported by MSP430F5359IPZ?

MSP430F5359IPZ supports both 4-wire JTAG and 2-wire Spy-Bi-Wire (SBW) interfaces via the RST/NMI/SBWTDIO and TEST/SBWTCK pins. SBW is enabled by default and requires only two pins for full debugging, flash programming, and real-time register inspection-ideal for space-constrained PCB layouts.
