MSP430G2553IPW28R

The MSP430G2553IPW28R from Texas Instruments is a 16-bit microcontroller based on the ultra-low-power MSP430 core. It operates at frequencies up to 16 MHz and features 16KB of Flash memory and 0.5KB of SRAM. This device supports multiple communication interfaces including I2C, SPI, and UART, making it versatile for various embedded applications.

Designed for low-power consumption, the MSP430G2553IPW28R has an active mode current draw of 230 µA at 1 MHz and 2.2 V, with standby and off modes consuming significantly less power. It operates within a supply voltage range of 1.8 V to 3.6 V and has an operating temperature range of -40°C to 85°C.

The microcontroller includes an 8-channel, 10-bit SAR Analog-to-Digital Converter (ADC) and up to 24 GPIO pins. It is available in a TSSOP-28 package, suitable for surface-mount applications. The device also features five power-saving modes and ultra-fast wake-up capabilities from standby mode.

Key features include a 16-bit RISC architecture, a basic clock module with internal frequencies up to 16 MHz, and two 16-bit Timer_A modules. The Universal Serial Communication Interface (USCI) supports enhanced UART, IrDA, and synchronous SPI. An on-chip comparator is also included for analog signal comparison.
