MSP430G2432IN20 Technical Specifications

MSP430G2432IN20 Key Features

• One core capability: a 16?bit CPU that delivers compact code density and faster integer math versus many 8?bit controllers.
• Integrated 10?bit ADC and analog front?end for direct sensor interfacing, which reduces BOM by eliminating external ADCs.
• Ultra?low?power architecture with five low?power modes, enabling longer battery life in intermittent or always?on applications.
• Universal serial interface (USI) supports UART, SPI, and I2C, improving board integration compared to controllers requiring separate UART/SPI hardware.

Typical Applications

• Battery?powered sensor nodes and data loggers that require milliwatt or microwatt standby, precise 10?bit conversions, and long runtime between charges.
• Industrial controls where a small DIP?20 footprint, industrial temperature range, and integrated timers simplify retrofit and legacy board designs.
• Human?machine interfaces with pushbuttons and LEDs, where multiple digital I/O lines and low active power reduce total system cost and heat.
• Serially controlled peripherals and standalone protocol bridges that need a compact MCU with USI for SPI/I2C/UART and deterministic timer control.

MSP430G2432IN20 Advantages vs Typical Alternatives

The device offers lower standby current and higher code density than many 8?bit MCUs, making it more energy efficient in idle?heavy designs. With a 16?bit core and a built?in 10?bit ADC, it combines tighter numeric range and native data width for simpler firmware than 8?bit parts plus external ADCs. The integrated USI and two 16?bit timers reduce external components versus discrete solutions. In short, it trades slightly higher per?unit MCU complexity for fewer external parts, smaller board area, and better power efficiency.
