Product details
Overview
MSP430F2350TRHAT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 16KB+256B flash, 2KB RAM, dual 16-bit timers (Timer_A3 and Timer_B3), USCI_A0/USCI_B0 serial interfaces (UART/IrDA/SPI/I²C), and an analog comparator-designed for battery-powered sensor nodes and portable instrumentation requiring sub-1µs wake-up and <0.1µA off-mode current.
For engineers reviewing the MSP430F2350TRHAT datasheet, MSP430F2350TRHAT pinout, MSP430F2350TRHAT application, or MSP430F2350TRHAT equivalent, key selection criteria include its 40-pin QFN (RHA) package, -40°C to +105°C industrial temperature grade, integrated DCO with factory-calibrated 1–16 MHz frequencies, and JTAG/emulation support via dedicated TCK/TMS/TDI/TDO pins.
Technical Context
The MSP430F2350TRHAT implements a 16-bit CPU with seven addressing modes and 51-instruction set, paired with a basic clock system supporting ACLK (32 kHz crystal or internal LF oscillator), SMCLK (DCO up to 16 MHz), and MCLK (system clock). Its five low-power modes-including LPM4 with 0.1 µA consumption-enable extended operation in energy-constrained systems.
Peripheral integration includes USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C) for flexible communication, Timer_A3 and Timer_B3 each with three capture/compare registers for PWM and timing, and Comparator_A+ supporting slope ADC and battery monitoring. All 32 I/O pins are individually configurable with programmable pullup/pulldown and edge-selectable interrupts on P1/P2.

FAQ
What is the operating temperature range of the MSP430F2350TRHAT?
The MSP430F2350TRHAT is specified for industrial operation from -40°C to +105°C. This extended temperature grade is confirmed in Table 1 of the SLAS518E datasheet under the "TRHA" ordering suffix, making it suitable for deployment in harsh environments such as motor control enclosures or outdoor sensor housings where ambient temperatures exceed standard commercial limits.
Does the MSP430F2350TRHAT support in-system programming without external hardware?
Yes, the MSP430F2350TRHAT supports in-system programming via its integrated Bootstrap Loader (BSL), accessible through UART pins P1.1 (RX) and P2.2 (TX). The BSL enables flash programming using only a standard serial interface and user-defined password protection-eliminating dependency on JTAG debuggers for field firmware updates.
How many I/O pins does the MSP430F2350TRHAT provide, and what are their capabilities?
The MSP430F2350TRHAT provides 32 dedicated I/O pins across Ports P1–P4, all individually configurable as digital inputs/outputs with programmable pullup/pulldown resistors. Ports P1 and P2 support edge-selectable interrupts on all eight bits, enabling precise wake-up from low-power modes based on external signal transitions.
What clock sources are available internally on the MSP430F2350TRHAT?
The MSP430F2350TRHAT integrates an internal digitally controlled oscillator (DCO) factory-calibrated to 1, 8, 12, and 16 MHz with ±1% accuracy, plus a very-low-power internal LF oscillator for ACLK. External options include 32 kHz crystal (XIN/XOUT), HF crystal/resonator up to 16 MHz, or external digital clock source-all managed by the Basic Clock System (BCS) module.
Is the MSP430F2350TRHAT pin-compatible with other devices in the MSP430F23x0 family?
Yes, the MSP430F2350TRHAT shares identical pinout and package (40-pin QFN, RHA) with MSP430F2330TRHAT and MSP430F2370TRHAT. All three devices have the same terminal functions, electrical characteristics, and mechanical footprint-enabling hardware reuse across memory variants without PCB redesign.
