Product details
Overview
M4FR5969SPHPT-MLS from Texas Instruments is a radiation-hardened 16-bit mixed-signal microcontroller featuring 64KB FRAM, 2KB RAM, 12-bit ADC with 16-channel analog input, AES-256 encryption coprocessor, and real-time clock with calendar function - deployed in spacecraft telemetry, sensor management, and radiation-tolerant data logging systems.
For engineers reviewing the M4FR5969SPHPT-MLS datasheet, M4FR5969SPHPT-MLS pinout, M4FR5969SPHPT-MLS application, or M4FR5969SPHPT-MLS equivalent, this page delivers verified radiation-hardened MCU specifications, HTQFP-48 package mapping, low-power mode current values (LPM3.5: 0.25 µA), FRAM endurance (1015 write cycles), and functional alternatives for space-grade embedded design.
Technical Context
The M4FR5969SPHPT-MLS implements a CPUXV2 core with 16 registers, integrated 32-bit hardware multiplier, and three-channel DMA - all operating within seven ultra-low-power modes optimized for distributed telemetry. Its FRAM memory architecture enables unified program/data/storage space with 125 ns per-word write speed and no erase-before-write requirement.
It integrates dual eUSCI modules supporting UART, IrDA, SPI, and I²C; five 16-bit timers with up to seven capture/compare registers each; and a 16-bit CRC engine. The device uses a flexible clock system with DCO (10 factory-trimmed frequencies), VLO, LFXT (32 kHz crystal), and HFXT support - all hardened against SEL (72 MeV·cm²/mg) and TID (50 krad).

Equivalent & Alternatives
The following parts are listed as comparable options for similar radiation-tolerant microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| M4FR5969SRGZT-MLS | Same die, 48-pin VQFN (7×7 mm) instead of HTQFP; no exposed thermal pad; slightly lower thermal resistance in convection-limited environments | Preferred for space-constrained PCB layouts where QFN footprint is acceptable and thermal pad routing is impractical | Select when board area is constrained and thermal dissipation via PCB copper is sufficient |
| MSP430FR5969-EP | Commercial temperature grade (−40°C to +105°C); non-radiation-hardened; no SEL/TID qualification; identical FRAM/peripheral set and pinout | Applicable for terrestrial high-reliability systems (e.g., downhole tools, avionics test equipment) where radiation tolerance is not required | Select for cost-sensitive, non-space applications requiring same architecture but without radiation assurance |
Compared with M4FR5969SPHPT-MLS, the VQFN variant offers identical functionality in a smaller footprint but reduced thermal margin, while the EP version removes radiation hardening to lower cost - making the SP-grade HTQFP optimal for mission-critical space deployments demanding SEL immunity and TID qualification.

FAQ
What is the maximum operating frequency of the M4FR5969SPHPT-MLS without FRAM wait states?
The M4FR5969SPHPT-MLS supports up to 8 MHz MCLK frequency with zero FRAM wait states (NWAITSx = 0). At higher frequencies (up to 16 MHz), one wait state is required, reducing effective throughput based on cache hit ratio. This behavior is documented in Section 4.3 of the SLASEK0A datasheet and applies identically to the M4FR5969SPHPT-MLS in HTQFP packaging.
Does the M4FR5969SPHPT-MLS support hardware AES encryption?
Yes, the M4FR5969SPHPT-MLS includes a dedicated AES-256 coprocessor with support for both 128-bit and 256-bit keys, enabling secure boot, encrypted data storage, and authenticated communication. It also provides a hardware random number seed generator for cryptographic key derivation - all confirmed in the "Code Security and Encryption" section of the SLASEK0A datasheet.
What is the radiation hardness specification for the M4FR5969SPHPT-MLS?
The M4FR5969SPHPT-MLS is radiation-hardened to SEL immunity of 72 MeV·cm²/mg at 125°C and total ionizing dose (TID) qualification of 50 krad(Si). It operates across −55°C to +105°C and features single-controlled baseline manufacturing - all verified per MIL-PRF-38535 Class V requirements and explicitly stated in the "Radiation-Hardness Assured" feature list of the SLASEK0A datasheet.
Which package type does the M4FR5969SPHPT-MLS use?
The M4FR5969SPHPT-MLS uses an HTQFP-48 package (7.0 mm × 7.0 mm, 0.5 mm pitch) with an exposed thermal pad. This is distinct from the RGZ (VQFN) variant M4FR5969SRGZT-MLS. Package dimensions and mechanical drawings are specified in Section 8 of the SLASEK0A datasheet under "Mechanical, Packaging, and Orderable Information."
Can the M4FR5969SPHPT-MLS operate with a 32-kHz crystal for real-time clock functionality?
Yes, the M4FR5969SPHPT-MLS supports a 32-kHz crystal connected to PJ.4 (LFXIN) and PJ.5 (LFXOUT) for RTC operation. The RTC_B module provides calendar, alarm, and calibration functions - confirmed in Section 1.1 ("Features") and Figure 1-1 (Functional Block Diagram) of the SLASEK0A datasheet. Crystal load capacitance is specified as 3.7 pF in footnote (3).
