MSP430G2533IPW28R Key Features
- Single 16-bit RISC core for compact code and faster integer math compared with 8-bit MCUs.
- Low-voltage operation (1.8?C3.6 V) to support longer battery life in portable and wireless systems.
- Small 28-pin TSSOP footprint that reduces PCB area and enables simpler board layouts versus larger packages.
- On-chip nonvolatile memory and SRAM that enable in-system firmware updates and reliable boot behavior.
- Standard debug/programming via SBW/JTAG for easier development and production programming.
- Industry temperature rating down to -40 ??C for more reliable operation in industrial environments.
Typical Applications
- Battery-powered metering modules where ultra-low active and standby power extend service intervals and reduce maintenance needs over years of field use.
- Industrial sensor nodes that require deterministic control, simple analog sampling, and robust operation across a wide -40 ??C to +85 ??C temperature range.
- Consumer and handheld devices that demand a small board footprint plus low-voltage operation to maximize run time on single-cell supplies.
- Embedded control in HVAC or appliance systems where compact packaging, reliable nonvolatile storage, and standard debug support speed development cycles.
MSP430G2533IPW28R Advantages vs Typical Alternatives
The MSP430G2533IPW28R offers a lower power profile and a smaller package than many mid-range MCUs, making it ideal for space- and energy-constrained designs. Its 16-bit architecture delivers more computational efficiency than 8-bit parts while keeping BOM and system complexity smaller than higher-end 32-bit MCUs. Standard SBW/JTAG support and a 28-pin TSSOP option simplify development and assembly compared with custom or less-supported alternatives.
