MSP430F233TPMR Key Features

• Single 16?bit RISC CPU for balanced processing and energy efficiency, enabling more arithmetic throughput than many 8?bit MCUs.
• Ultra?low power operation with multiple low?power modes to extend battery life in portable and remote systems.
• Integrated 10?bit ADC for direct sensor interfacing, reducing bill of materials by removing external converters.
• Flexible USCI serial module that supports UART, SPI and I2C, simplifying connectivity to peripherals and networks.
• Compact 20?pin TSSOP package for smaller boards and higher board density compared with larger packages.

Typical Applications

• Battery?powered sensor nodes that need low active current and long sleep intervals while performing occasional 10?bit conversions and serial telemetry.
• Handheld diagnostic and measurement tools that benefit from a 16?bit core for faster numeric handling and lower power than larger microcontrollers.
• Industrial control modules with constrained space that require PWM/timer control, ADC sampling and reliable UART or SPI links to peripheral modules.
• Consumer portable devices that demand sub?milliamp sleep current, compact 20?pin packaging and integrated analog front?end for cost?effective designs.

MSP430F233TPMR Advantages vs Typical Alternatives

The device offers a clear tradeoff between capability and power. Compared with common 8?bit MCUs, it delivers more native 16?bit arithmetic performance and a 10?bit ADC while still preserving lower standby currents than many 32?bit parts. Compared with larger MSP430 variants it reduces board area and cost with a 20?pin TSSOP package and smaller memory footprint. Use it when you need better computation than 8?bit devices, lower power than midrange 32?bit MCUs, and integrated analog plus serial peripherals in a compact form.

FAQ

What package is used?

The part is supplied in a 20?pin TSSOP package (PMR suffix). This small outline package reduces PCB area while keeping accessible GPIO and peripheral pins for compact designs.

Does it support serial protocols?

Yes. The device includes a universal serial communication interface (USCI) that supports UART, SPI and I2C modes. This lets engineers connect displays, memory and sensors without extra bridge chips.

What analog capability exists?

It integrates a 10?bit analog?to?digital converter suitable for many sensor inputs. The ADC removes the need for an external converter in many measurement and monitoring applications.

What are the power advantages?

Multiple low?power modes let the MCU sleep with minimal current draw and wake quickly for short tasks. This balance preserves battery life while maintaining adequate real?time responsiveness.

Is it suitable for battery systems?

Yes. The wide operating voltage range from 1.8 V to 3.6 V matches common single?cell and rechargeable battery chemistries, making it suitable for portable and remote monitoring systems.
