See the SYSOSC section of the technical reference manual for details on computing SYSOSC accuracy. (2) SYSOSC Accuracy is measured in the default power-up state, with MCLK = SYSOSC, the CPU is running a while(1) loop, and the SYSPLL is disabled. (3) SYSOSC is measured with the internal FCC counter using an external 1ms pulse as the measurement trigger. 7.8.2 High Frequency Crystal/Clock over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT High frequency crystal oscillator (HFXT) fHFXT HFXT frequency HFXTRSEL=00 4 8 MHz HFXTRSEL=01 8.01 16 HFXTRSEL=10 16.01 32 HFXTRSEL=11 32.01 48 MHz DCHFXT HFXT duty cycle HFXTRSEL=00 40 65 % HFXTRSEL=01 40 60 HFXTRSEL=10 40 60 HFXTRSEL=11 40 60 OAHFXT HFXT crystal oscillation allowance HFXTRSEL=00 (4 to 8MHz range) 2 kΩ CL, eff Integrated effective load capacitance(1) 1 pF tstart, HFXT HFXT start-up time (2) HFXTRSEL=11, 32MHz crystal 0.5 ms IHFXT HFXT current consumption fHFXT=4MHz, Rm=300Ω, CL=12pF 75 µA fHFXT=32MHz, Rm=30Ω, CL=12pF, Cm=6.26fF, Lm=1.76mH 600 High frequency digital clock input (HFCLK_IN) fHFIN HFCLK_IN frequency (3) USEEXTHFCLK=1 4 48 MHz www.ti.com MSPM33C321A, MSPM33C3219 SLASFB6A – DECEMBER 2025 – REVISED SEPTEMBER 2026 Copyright © 2026 Texas Instruments Incorporated Submit Document Feedback 49 Product Folder Links: MSPM33C321A MSPM33C3219 |
