Frequently Asked Questions
How does the hardware floating-point unit in TM4C1236E6PMI7R benefit motor control firmware at 80 MHz?
TM4C1236E6PMI7R's Cortex-M4F FPU executes 32-bit single-precision floating-point multiply-accumulate operations in a single clock cycle at 80 MHz, compared with 20–100 cycles required for software floating-point emulation on an M3 core. This throughput advantage allows field-oriented control loops with trigonometric transforms to complete within the 50 µs interrupt period of a 20 kHz PWM cycle, leaving sufficient cycles for communication and diagnostics.
What is the flash memory capacity of TM4C1236E6PMI7R and how does it compare within the TM4C123x family?
TM4C1236E6PMI7R integrates 128 KB of on-chip flash, which places it in the mid-tier of the TM4C123x family — below the 256 KB of TM4C1237E6PM but sufficient for typical RTOS kernels of 20–40 KB plus application code. The 64-pin LQFP package version designated by the 'PMI' suffix is pin-compatible with other TM4C123x LQFP-64 variants, enabling a firmware-only upgrade path to higher flash density without PCB respins.
Which industrial applications are best matched to TM4C1236E6PMI7R's 64-LQFP footprint and peripheral set?
The 64-LQFP 10 mm x 10 mm footprint and on-chip ADC make TM4C1236E6PMI7R well-suited for compact industrial panel meters, energy monitoring nodes, and 3-phase motor inverter controllers that require ≥4 PWM outputs and ≥8 ADC channels in a through-hole or surface-mount footprint under 15 mm x 15 mm. Its integrated DMA reduces CPU load during high-speed SPI or UART data transfers to communication modules, maintaining real-time control loop timing.
What procurement risk does TM4C1236E6PMI7R's YTEOL=0 status present for new designs?
A YTEOL (Years to End of Life) value of 0 indicates TM4C1236E6PMI7R is at or past its end-of-life date in TI's lifecycle database, meaning last-time-buy windows may have closed and new production quantities are limited or unavailable. Engineers starting new designs in 2024 or later should evaluate active-production alternatives such as TM4C1237H6PM or the newer TM4C129x family, which provide the same Cortex-M4F core with larger flash, additional peripherals, and confirmed 10+ year availability from TI.
