  • (MCU_OSC0 Switching Characteristics - Crystal Mode): Added ANI package option to the tableGo
  • (GPMC): Widened range of output load capacitance. Specified separate ranges for 133MHz Synchronous Mode and All other modes.Go
  • (GPMC and NOR Flash Timing Requirements — Synchronous Mode): Simplified MODE column to include only div_by_1_mode and not_div_by_1_mode. Changed column headers from GPMC_FCLK = 100MHz/133MHz to 32-bit data bus (up to 100MHz)/16-bit data bus (up to 133MHz). Simplified several parameter descriptions. Updated pin names to match Pin Attributes table. Updated the table notes. Go
  • (GPMC and NOR Flash Switching Characteristics – Synchronous Mode): Removed the MODE column. Combined the GPMC_FCLK=100MHz and GPMC_FCLK=133MHz columns. Reduced F2 and F3 clk-csn maximum output delays. Changed the timing variable in parameters F3 and F11 to "D". Removed 2 of the F7 rows. Removed the "J" timing variable from the F15 and F17 parameters. Added byte enables for 32-bit data bus to F6, F7, F17, F19. Simplified several parameter descriptions. Updated pin names to match Pin Attributes table. Updated the table notes.Go
  • (GPMC and NOR Flash Timing Requirements – Asynchronous Mode): Removed the MODE column and the table note that described register configuration for div_by_1_mode. Added the correct table note for parameter FA21 Go
  • (GPMC and NOR Flash Switching Characteristics – Asynchronous Mode): Removed the MODE column and redundant rows. Also removed the table note that described register configuration for div_by_1_mode. Moved links to table notes directly next to each letter. Go
  • (GPMC and NAND Flash Timing Requirements – Asynchronous Mode): Removed the MODE column and the table note that described register configuration for div_by_1_mode.Go
  • (GPMC and NAND Flash Switching Characteristics – Asynchronous Mode): Removed the MODE column and the table note that described register configuration for div_by_1_mode. Added table notes and associated reference links for timing variables A, B, C, D, E, F, G, H, I, K, L, and M.Go
  • (MCSPI Switching Characteristics – Peripheral Mode): Updated values for parameters SS6 and SS7Go
  • (Device Naming Convention): Updated Package Designator row (added ANI package option)Go

Changes from June 3, 2026 to June 12, 2026 (from Revision I (JUNE 2026) to Revision J (JUNE 2026))

  • (Speed Grade Maximum Frequency): Added a VDD_CORE column, indicating that both 0.75 V and 0.85 V core voltages are supported across all Speed Grade optionsGo
  • (Thermal Resistance Characteristics): Updated ANI package characteristics valuesGo
