Texas Instruments MSP430F5633IPZ

Overview

MSP430F5633IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB flash, 16 KB + 2 KB RAM, USB 2.0 full-speed interface, dual USCI modules (UART/IrDA/SPI/I²C), 12-bit ADC with 16 channels, and four 16-bit timers - deployed in portable sensor systems and battery-powered thermostats requiring sub-2 µA LPM3 standby current.

For engineers reviewing the MSP430F5633IPZ datasheet, MSP430F5633IPZ pinout, MSP430F5633IPZ application, or MSP430F5633IPZ equivalent, key selection criteria include USB integration without external PHY, 74 I/O pins in LQFP-100, RTC with battery backup, and verified 3 µs wake-up from LPM3 for time-critical sensing duty cycles.

Technical Context

The MSP430F5633IPZ implements a CPUXV2 core with constant generators and 16-bit RISC architecture, operating up to 20 MHz via FLL-stabilized DCO or external crystals (XT1/XT2). Its unified clock system supports simultaneous ACLK, SMCLK, and MCLK domains with programmable LDO core regulation.

Peripherals are memory-mapped and synchronized through a 6-channel DMA controller. The USB module integrates PHY, PLL, 3.3-V/1.8-V power system, and eight endpoints - enabling self-contained HID or CDC device implementation without external components.

Key Specifications

Pinout & Package

LQFP-100 package (14 mm × 14 mm), thermally enhanced with exposed thermal pad; pin-compatible with other MSP430F563x IPZ variants including MSP430F5632IPZ and MSP430F5634IPZ.

FAQ

What is the maximum system clock frequency supported by the MSP430F5633IPZ?

The MSP430F5633IPZ supports up to 20 MHz system clock via its digitally controlled oscillator (DCO) with FLL stabilization, or from external high-frequency crystals up to 32 MHz on XT2. This enables deterministic real-time processing for time-critical sensor sampling and USB packet handling without overclocking risk.

Does the MSP430F5633IPZ include an integrated DAC?

No, the MSP430F5633IPZ does not include DAC channels. As confirmed in Table 6-1 (Device Comparison), DAC12_A is marked with "–" for this part number - distinguishing it from MSP430F5638IPZ and MSP430F5637IPZ which feature two 12-bit DACs. This omission reduces cost and power for purely digital-sensing applications.

What USB speed and endpoint configuration does the MSP430F5633IPZ support?

The MSP430F5633IPZ supports full-speed USB 2.0 (12 Mbps) with eight bidirectional endpoints (four IN, four OUT), integrated PHY, USB-PLL, and dual-voltage power system (3.3 V and 1.8 V). This allows implementation of standard USB device classes including CDC, HID, and MSC without external transceivers or clock sources.

How many I/O pins does the MSP430F5633IPZ provide in the LQFP-100 package?

The MSP430F5633IPZ provides 74 general-purpose I/O pins in the LQFP-100 package, as specified in the Device Comparison table and functional block diagrams. These include P1–P9 ports with configurable interrupt, drive strength, and peripheral mapping - supporting complex peripheral interfacing in space-constrained designs.

What is the typical current consumption of the MSP430F5633IPZ in LPM3 standby mode?

The MSP430F5633IPZ draws 1.8 µA at 2.2 V and 2.1 µA at 3.0 V in LPM3 mode (watchdog + crystal + full RAM retention), per Section 8.5 of the datasheet. This ultra-low quiescent current enables multi-year operation on standard CR2032 coin cells in always-on sensing applications.
