Hardware Features
2.2.1
MSP430G2553 MCU
The MSP430G2553 is a member of the MSP430 family of ultra-low-power MCUs. MSP430 MCUs features
different sets of peripherals targeted for various applications. The MCU architecture, combined with five
low-power modes, is optimized to achieve extended battery life in portable measurement applications.
Device features include:
•
1.8-V to 3.6-V operation
•
16-bit RISC architecture up to 16-MHz system clock
•
16KB of flash memory and 512 bytes of SRAM
•
8-channel 10-bit ADC
•
8-channel comparator
•
Two 16-bit timers with three capture/compare registers (Timer_A)
•
24 GPIOs
•
One universal serial communication interface (USCI_A) supports UART, IrDA, and SPI
•
One USCI (USCI_B) supports SPI and I

2.2.2
eZ-FET Onboard Debug Probe With EnergyTrace Technology
To keep development easy and cost effective, TI's LaunchPad Development Kits integrate an onboard
debug probe, which eliminates the need for expensive programmers. The MSP-EXP430G2ET has the eZ-
FET debug probe (see
), which is a simple and low-cost debugger that supports all MSP430
MCUs.
