Product details
Overview
MSP430F2370IYFFT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32KB Flash + 256B information memory, 2KB RAM, dual 16-bit timers (Timer_A3 and Timer_B3), a universal serial communication interface (USCI) supporting UART/IrDA/SPI/I²C, and an on-chip analog comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation requiring sub-µA standby current.
For engineers reviewing the MSP430F2370IYFFT datasheet, MSP430F2370IYFFT pinout, MSP430F2370IYFFT application, or MSP430F2370IYFFT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for low-power embedded design.
Technical Context
The MSP430F2370IYFFT implements a 16-bit CPU with seven addressing modes and a hardware multiplier supporting signed/unsigned 16×16 operations. Its clock system integrates a digitally controlled oscillator (DCO) calibrated to ±1% at 1/8/12/16 MHz, plus support for external 32-kHz and up-to-16-MHz crystals or resonators.
It features two independent 16-bit timers-Timer_A3 with three capture/compare registers and Timer_B3 with identical structure-plus USCI_A0 (UART/IrDA/SPI) and USCI_B0 (SPI/I²C), enabling simultaneous asynchronous and synchronous communication. The on-chip Comparator_A+ supports slope A/D conversion and battery monitoring without external components.

FAQ
What is the maximum operating frequency of the MSP430F2370IYFFT?
The MSP430F2370IYFFT supports a maximum system clock (MCLK) of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO). This frequency is confirmed in the SLAS518E datasheet Section "Basic Clock Module Configurations" and enables instruction execution at 62.5-ns cycle time. The DCO is stable across voltage and temperature, and MSP430F2370IYFFT maintains full functionality at this rate within its 1.8–3.6 V supply range.
Does the MSP430F2370IYFFT support hardware UART with auto-baudrate detection?
Yes, the MSP430F2370IYFFT's USCI_A0 module supports enhanced UART with automatic baudrate detection (LIN-compliant), as specified in the "Universal Serial Communications Interface (USCI)" section of SLAS518E. This feature allows MSP430F2370IYFFT to synchronize to incoming LIN frames without prior knowledge of bit rate - critical for automotive diagnostics and interoperable sensor networks.
How many I/O pins does the MSP430F2370IYFFT provide in the YFF package?
The MSP430F2370IYFFT in the 40-pin QFN (YFF) package provides 32 dedicated general-purpose I/O pins across Ports P1–P4, as documented in the "Device Pinout, YFF Package" diagram and Table 3 ("Terminal Functions"). All 32 pins support individually programmable direction, pullup/pulldown resistors, and edge-selectable interrupts on P1/P2 - matching the functional I/O count stated in the device description.
Is the MSP430F2370IYFFT pin-compatible with the MSP430F2350IYFFT?
Yes, the MSP430F2370IYFFT and MSP430F2350IYFFT share identical 40-pin YFF packaging, pin assignments, and electrical characteristics per Table 1 ("Available Options") and Table 3 ("Terminal Functions") in SLAS518E. Both devices are drop-in replacements in hardware design - differing only in Flash memory size (32KB vs. 16KB) and are software-binary compatible within their respective memory footprints.
What development tools are officially supported for programming the MSP430F2370IYFFT?
Texas Instruments officially supports the MSP-FET430UIF (USB JTAG), MSP-FET430PIF (parallel port), and MSP-GANG430 (production programmer) for MSP430F2370IYFFT, as listed under "Development Tool Support" in SLAS518E. These tools enable full flash programming, debugging, and security fuse configuration - and MSP430F2370IYFFT requires no external programming voltage due to its onboard serial bootloader and JTAG interface.
