Product details
Overview
MSP430FR5957IDA from Texas Instruments is an ultra-low-power 16-bit FRAM microcontroller with 32KB nonvolatile memory, 1KB RAM, 12-bit ADC (14 external channels), RTC with calendar/alarm, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets energy-harvested sensor nodes and wearable electronics.
For engineers reviewing the MSP430FR5957IDA datasheet, MSP430FR5957IDA pinout, MSP430FR5957IDA application, or MSP430FR5957IDA equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (0.25 µA typical), HFXT support for high-precision timing, and TSSOP-38 package compatibility with space-constrained PCB layouts.
Technical Context
The MSP430FR5957IDA integrates a 16-bit CPUXV2 core with a flexible clock system including DCO (10 factory-trimmed frequencies), HFXT (high-frequency crystal oscillator), and VLO (low-power internal source). Its real-time clock (RTC_B) requires HFXT operation and supports calendar mode with alarm interrupts.
Peripherals include five 16-bit timers (TA0–TA3, TB0), 3-channel DMA, 16-channel analog comparator, AES256 encryption coprocessor, and capacitive touch I/O on all pins without external components - enabling low-power human-interface sensing in battery-operated devices.

FAQ
What is the maximum operating frequency of the MSP430FR5957IDA?
The MSP430FR5957IDA supports a maximum system clock frequency of 16 MHz using its integrated digitally controlled oscillator (DCO) or external HFXT crystal. This enables real-time signal processing and responsive peripheral handling while maintaining ultra-low-power operation across all active and low-power modes.
Does the MSP430FR5957IDA include hardware encryption capabilities?
Yes, the MSP430FR5957IDA integrates a dedicated AES256 security coprocessor with support for both encryption and decryption, plus a random number seed generator. This enables secure firmware updates, encrypted data storage in FRAM, and cryptographic authentication without burdening the main CPU - essential for certified IoT and industrial applications.
How many analog input channels does the MSP430FR5957IDA ADC support?
The MSP430FR5957IDA features a 12-bit ADC12_B module supporting up to 14 external analog input channels (A0–A15, excluding A6 and A7) and 2 internal sources. Channel mapping is confirmed in Table 4-1 of the SLAS704G datasheet, with inputs routed through P1.x, P3.x, and P4.x pins depending on package variant.
Is the MSP430FR5957IDA pin-compatible with other devices in the MSP430FR59xx family?
Yes, the MSP430FR5957IDA in the 38-pin TSSOP (DA) package shares identical pinout and signal mapping with MSP430FR5958IDA and MSP430FR5959IDA. This allows direct substitution within the same footprint for memory-scaling design iterations without PCB redesign or layout changes.
What crystal oscillator options does the MSP430FR5957IDA support?
The MSP430FR5957IDA supports HFXT (high-frequency crystal oscillator) for frequencies between 4 MHz and 24 MHz, enabling precise system timing and RTC calibration. It does not support LFXT (32-kHz crystal) - that option is reserved for MSP430FR594x variants. HFXT operation is mandatory for RTC_B functionality in this device.
